astrophotography settings a7iii

Which means higher iso. Live View Focusing and Framing And the new a7sIII rumoured to come out soon would also be interesting to test. SONY: I deducted marks from the Sony a7III for deep-sky imaging for its lack of a light frame buffer, poor red sensitivity, odd LENR performance, and purple amp glow not seen on the other cameras and that dark frames did not eliminate. You’ll see how different the stars are rendered with all those programs. I expected the new BSI-equipped Sony to better the Nikon by about a stop. But if the Sony had a built-in intervalometer…! Sensors with 4 micron pixels will have more noise than sensors with 6 micron pixels, no matter what size the sensor is. At last, we have a mirrorless camera that not only doesn’t eat stars, it also does not eat batteries! I would like to receive information about it! Thanks! Thank you very much again! the 500 rule is pretty bad for today's cameras. On the a7iii the differences between iso 400 and iso 640 pushed to be equal exposure, the 640 image is cleaner even with a shorter shutter time due to the dual gain system ‘kicking in’ at iso 640. But the dark shadows in underexposed nightscapes withstood shadow recovery better in the uncompressed files. Post was not sent - check your email addresses! The red and blue colors of those stars are wiped by the filter – just as it has been since firmware update 4.0 on the A7RII. Well pro’s use tools and programs (apps) on a camera that get the end result they want/need without hauling valuable gear to a site to capture. Hi Alan, thanks for this detailed review. Don’t believe me? This is good news, as astrophotography requires fast, high-quality lenses, and the Sony allows more choices. Only Slot 1 will work with the fastest UHS II cards that are needed for recording the highest quality 4K video. “The 2008-vintage 5D MkII had a 5-frame buffer!” With the Canon full-frames you simply fire the shutter again. I bought one and I'm truly enjoying it for night photography. I feel that in the a7III the Star Eater has been largely vanquished. For astrophotography, none of those auto functions are of any value. Exposure is set with the camera shutter speed making 30s the maximum. Older cropped-frame cameras (Canon 7D MKII) might have worse noise because they are older and use older firmware. I love it! first, the stars on your images are extended typically on 3 pixels, so they are not as dramatically reduced as stars extended on a single pixel. Maybe a bit noisy (hard to tell as I had a CLS filter), but still interesting to look at ^, [���][deleted] 1 point2 points3 points 2 years ago (1 child), 24mm you're gonna wanna keep shutter speed at around 15 seconds to not get visible trails. In Single drive mode, stars and noise soften ever so slightly at 4 seconds and higher. A7iii and 70 200 F4. You can take full advantage of wide-angle lenses, great for auroras. Due to limitations set by Sony, controlling one of their cameras with an external controller can be problematic. As such, I would have expected a more uniformly illuminated sensor. If it did then the massive foot-wide cameras used at observatories would have no noise at all! For use on telescopes, the simple adapters will be sufficient, and necessary as many telescope-to-camera adapters and field flatteners are optimized for the longer lens flange-to-sensor distance of a DSLR. But it is compatible with many external intervalometers and controllers. I can’t speak for other Sonys but in the a7III it is not so much an issue of “star eating” but “star rendering.” But Nikons have similar issues of oddly colored stars. Stars were smoothed away along with the noise in exposures longer than 3.2 seconds in some Sony cameras (longer than 30 seconds in others). The latest iteration of the menu interface is much improved on the a7III. Go figure! While these might add glows to long exposure images, if they could be designed not to do that (i.e. In Movie Mode ISO speeds go up to ISO 102,400, but are pretty noisy, if unusable at such speeds. It is not clear if Sony’s compressed Raws are 12-bit vs. 14-bit for uncompressed files. • It lacks the “light-frame” buffer offered by full-frame Canons that allows shooting several frames in quick succession even with LENR turned on. I have the A7S, A7RM2 and A7M3 and have been playing with the A7S since 2014, 2016 A7RM2 and 2018 A7M3 with Astro MW and other things. Even a supposedly ISO invariant Camera like the Sony can show noise and discoloration in underexposed images boosted later in exposure. I have a Sony A7Sii and I have not used it for a night photography or for deep sky, but I’m going to now, I’ve been away from the Hobby for a while and want to get back into the deep sky stuff. I have chosen late model full-frame cameras and a cropped frame camera each from Sony, Canon, and Nikon. Nevertheless, for the demands of nightscape and deep-sky shooting and processing, I suggest shooting Uncompressed Raws. And in tracked exposures over a minute where you’d really see the difference there is virtually no difference in sharpness, star count and limiting magnitude between the Sony and cameras not accused of eating stars. But that’s not removing stars. Change ), You are commenting using your Google account. I don’t know if Nikon is still using Sony sensors but both brands seem to be making very good cameras. Posted by 2 years ago. Thank you for a detailed review of the Sony 7III. Using other Raw converters might affect this. Why would that be? I would not recommend the a7III for deep sky. The Sony A7iii is a powerhouse but to unlock its full power you need to be able to get into the settings. Or is this just a theory of how it should behave? The Sony would perform better in an ISO Invariancy “face-off” if its ISOs were kept above 640, to keep all the images within the Sony’s upper ISO range of its dual-gain sensor design, with two ranges (100 to 400, and 640 on up). OK, let’s try that. You obviously put some time into your tests. The compact a7III body weighs a measured 750 grams, vs. 900 grams each for the Nikon D750 and Canon 6D MkII. But in my suggested test we are keeping the camera and sensor the same. Best Astrophotography Settings for A7iii (self.SonyAlpha). Thanks Steve! For most people, the a7III is going to downright rock at low-light and landscape astrophotography. Time-Lapse Smoothing  Is it iso invariant enough that it doesn’t matter, or are certain iso’s slightly better in your opinion for night sky images than the tier 2 base iso of 640? The lower weight can be helpful for use on lightweight telescopes, on small motion control devices, and for simply keeping weight and bulk down when traveling. Stars are visible to the same limiting magnitude and close double stars are just as well resolved across all exposures. Overall, I’d rank this lens number two out of the four lenses in this post. Up to now my report on the Sony a7III hasn’t shown as glowing a performance as all the YouTube reviews would have you believe. This isn’t a huge detriment, as anyone who really wants to go after deep nebulosity must use a “filter-modified” camera anyway. However, I did not consider “star eating” to be a negative factor, as the Sony showed just as many stars and as well-resolved as did the competitors, and what more could you ask for? 留99, 留7s, 留7r + Zeiss 16-35/E35/50/85/135, A7Riii | A7ii infrared mod | Minolta ���7, A7RII Batis 85 f/1.8 // A5100 50 f/1.8 // A6000 18-105 f/4, A9 | A7Riii | Sony Pro | Thanks for reading! In-Camera Image Stacking  Get an ad-free experience with special benefits, and directly support Reddit. And, as I found, the Sony might need to be placed into Continuous shooting mode to have the shutter fire with every trigger pulse from the motion controller. Sony a6000 Moon Settings – Intro. I appreciate the work and dedication. Hi Alan, Just wondering if you have done a test of the dark frame noise from the a7iii, or for any of your camera reviews. The small tree at the top of the image looked very different with the two cameras. When comparing 1600 to 1600 from my a7ii to a7iii there isn’t much in it, 3200 vs 3200 it’s maybe half a stop – 6400 maybe 2/3 of a stop. The S/N ratio is determined by the individual pixels — they don’t know how big a sensor they belong to and won’t behave differently in a cropped sensor vs a large sensor. It was not supplied to me by Sony in return for an “influential” blog post. Yes, that’s right Steve. Here are the first lenses you should buy, Brian Smith's guide to lens adaptors for E-mount cameras, Phillip Reeve's beginner's guide to manual lenses on the A7, Astrophotography tutorials & reviews at The Lonely Speck, Sony Alpha Rumors - find out what's coming next. It’s not the debayering which causes the color shift, as those stars are white in images with 3.2 s and become green at 4 s exposure time. I put this on C1. At F4, you should push the shutter speed to 20s. I put the new Sony a7III mirrorless camera through its paces for the features and functions we need to shoot the night sky. So it is great to have one available on the Sony. But with the Nikon you would be buying all new lenses I would imagine. So even if you should only do a 12 second shot for no star trails with a 12mm f/4 for a big print you can increase the ISO or just leave at 800 and brighten in post. The Sony test report is revised to explain this. Certainly not as good as the Canon rendered with Camera Raw. I just want to address, in amateur fashion, the very basic aspect: incoming photons collected by a pixel. Contrary to expectations, the Sony did not show any great loss in image quality as it crossed the ISO 640 boundary into its lower ISO range. Both the Sony and Nikon use sensor and signal path designs that are “ISO invariant.” As a result, images shot underexposed at slower ISOs, then boosted in exposure later in processing look identical to properly exposed high-ISO images. For astrophotography, none of those auto functions are of any value. In conclusion, here’s my summary recommendations for the three competitive cameras, rating them from Poor, to Fair, to Good, to Excellent. Again, here I show only the Sony and Nikon, the two “ISO invariant” cameras. It’s not strictly hardware nor just software. It���ll be ok at 3200. See, With the Alpine Laboratories Radian2, exposure ramping is not possible with a Sony, only basic shutter triggering. I find there’s more of a gap the higher of an ISO you use. Intervalometer — NOW INCLUDED! I shot images over a wide-range of exposures, from 2 seconds to 2 minutes, but show only the ones covering the 2-second to 4-second range, where the “star-eater” anti-aliasing or noise smoothing applied by Sony kicks in (above 3.2 seconds it seems). As you surmised, the a7III is the first and only Sony mirrorless I’ve used. It’s all about the Focus Peaking, which I’ll get to in the camera settings below. With DSLRs it is the raised mirror which often casts a shadow, produced a dark vignetted band along the bottom of the frame. © 2020 reddit inc. All rights reserved. Even with Canons that have a Bulb Timer for exposures >30s you can’t use it with the internal intervalometer. Yes, this can all be done later in processing, but having the camera do the stacking can often be convenient, and great for beginners, as long as they understand what those functions do, or even that they exist! When opening the same Raws in other programs (ON1 Photo RAW, Affinity Photo, DxO PhotoLab, and Raw Therapee) the results can be quite different, with stars often rendered with fringes of hot, colored pixels.

That’s why using exactly same sensor, different make and model cameras may produce diff quality images.). Full-frame and cropped-frame cameras with similar sized pixels have similar levels of noise. For astrophotography, I carry the Sony 16-35mm f/2.8 G Master, Sony 12-24mm f/4 G, the Zeiss Batis 18mm f/2.8, and now, the low light monster Sony 24mm f/1.4 G Master. I wanted to comment on one thing, after reading the entire publication, I have the question of whether the sony a7iii has to be compared with the canon 6d mark ii or with the 5d mark iv (and the same with nikon, although I don’t know the name of the model higher). If you have ever looked at the apps on Playmemories site (a selling point when I bought the A7S back in 2014 [no other camera offered and is ground breaking]). Thanks! But the Sony, being four years newer than the Nikon, is not better. In real life images, such as I have shown, it makes very little difference even in deep-sky images which are the most demanding of star quality. I show only the Sony and Nikon compared here, shot at the common range of ISOs used for nightscape shooting, 800 to 12800. Effectiveness of Long Exposure Noise Reduction (LENR), Quality of Raw files, such as sharpness of stars, Brightness of Live View for framing and focusing. Exceptions are images taken for star trail stacking and for time-lapses, images that must be taken in quick succession, with minimal time gap between frames. Hi and thanks! But the a7III should do the job for bright auroras, the ones with rapid motion worth recording with video, plus offer 24 megapixels for high-quality stills of all sky subjects. (what software subtracts such dark frames? These are from DPReview’s noise comparison test images. The Sony still showed some discoloration artifacts and added noise when boosting images by +4 EV that the Nikon did not. Use the ISO that will produce a well exposed histogram for the shutter speed and aperture dictated by the scene. Electronic Front Curtain Shutter Assign it to one of the hardware Custom C buttons. It may be more serious on other Sony alphas. Bright Monitoring does not appear in any of the in-camera menus you can scroll through, so you won’t stumble across it. To my eye, the difference is nothing like the huge wiping out of stars reported and shown at Lonely Speck. Canon and Nikon both offered factory modified cameras at one time, notably the Canon 60Da and Nikon D810a. Anyway, the a7III does look compelling. With the 6D it was 4 if it was on Raw+JPG. In models from a similar generation it will always be the ones with the larger pixels — regardless of sensor size. The Canon 5D series also has this. Summary: • It offers as low a noise level as you’ll find in a 24-megapixel full-frame camera, though its noise was not significantly lower than the competitive Sony a7III, nor even the older Nikon D750. [���]4armo 0 points1 point2 points 2 years ago (0 children). These beginner-friendly camera settings and tips should help you get your first successful image of the night sky. Full resolution examples of the “Star Eater” issue are available for download here (.zip, 8.4MB).. Change ). By default, the a7R III is set to shoot in the sRGB color space, which is the most universally used & accepted color space for the … Change ), You are commenting using your Facebook account. Most DSLRs do not offer this, but the Sony’s option of an electronic front curtain shutter and the additional Silent Shooting mode completely eliminates vibration, useful for some high-magnification shooting through telephotos and telescopes. The A7M3 continuously amazes me and your review is spot on. Do you know that for a fact from personal tests? I’ve noticed you’ve used the Rokinon 14mm SP on the a7iii in your noise test. Try it. The D750 is fabulous but the Sony is almost as good – much better for Live View – and accepts all lenses. It is possible some of the artifacts I saw are due to ACR not handling the a7III’s .ARW files as well as it should. Give me a Canon full-frame any day for prime-focus deep-sky shooting. Light Frame Buffer in LENR ; 1.2 Bracket Settings: -0+ order, which I find makes it much easier to group brackets when post-processing. While you can look through and frame using the EVF as you would with a DSLR, you are looking at an electronic image from the sensor, not an optical image from the lens. with LENR “on” with “lens cap on” to get a larger sampling of dark frames, to manually subtract in post? Jim Kasson’s testing ( provides strongly conclusive evidence that it is still present, and your first comparison shot with the Canon 6d shows small stars in the Sony that are characteristically ragged and with a dominance of green colour – exactly the features explained in Mark Shelley’s reverse engineering of Sony’s latest spatial filtering algorithm. Stars 1 or 2 pixels wide are a little too colorful! This is most noticeable – indeed usually only noticeable – when shooting deep-sky targets though telescopes. The cause is not clear. The built-in Sony SteadyShot system promises to offer about 4.5 stops of stabilization capability which should help reduce the effects of camera shak… Canon really needs to improve their sensors to keep in the game. The dark frame kicks in and locks up the camera only after the series of “light frames” are taken. I have used Sony cameras for astrophotography for years and have never noticed a star eater problem. You have ignited my fuse, thank you for that. Instead, I saw a slight shadowing at the top and bottom edges but just at the corners. Archived. Lighter Weight / Smaller Size Best Astrophotography Settings for A7iii. a7rIII vs a9 for Astrophotography: 01Ryan10 wrote: Pentax K-1. We shoot everything on manual. The settings menu is still exceptionally long and deep, but functions have been categorized into useful groups and as a … In your theory the image taken with it set to shoot full frame should be less noisy. With the 5D MKII you could take 5 lights. then, even in your case with ~3pixels wide stars, the comparison between 3.2s and 4s clearly shows a reduction of the stars “peak” brigthness, and notably less weak stars. I had originally remarked that this useful function was missing. I did notice the difference in detail between the Nikon and the Sony on the cropped in, ISO invariance test shots. An example is in a 4K video I shot on May 6, 2018 of an usual aurora known as “STEVE.”. Hi, it all depends on what you want to buy or already have for lenses. Perhaps I’ll add examples to show that, but I would invite you to take your own Raw files of tracked star images shot with a Sony, Nikon, and Canon camera and develop them with Adobe Camera Raw, Capture One, DxO, Affinity, Luminar, ON1 Photo RAW, and Raw Therapee’s various modes. Great article. Sony not performing as good as competitors? Shutter speeds can be as slow as 1/4-second, allowing real-time aurora shooting at reasonable ISO speeds. I can assure you that even the ace programmers of Raw development software who I have spoken to are puzzled by this as well. The Sony a7III uses a sensor that is “Backside Illuminated,” a feature that promises to improve low-light performance and reduce noise. I.E. Here’s the cool part: Take the same lens and adapter and mount it on the a6300 or a6500 and now you have a 25.5mm lens. I have found the use of the Digital Filter app really good to capture the Milky Way above Sky Glow. With a fast enough UHS-II Class card it can record 4K video up to 30 frames per second and at a bit rate of either 60 or 100 Mbps. Custom Key Settings: Custom Button 1 — Focus Mode. Dual Card Slots  I saw none of the extreme effects reported by others with other Sonys, where masses of faint stars disappeared or turned into multi-colored blotches. Try 24mm, f/4, 15 seconds, iso 1600. I use a Canon T5i right now as I’m new to the craft. The area of the sensor as a whole has nothing to do with if. And note that 15s shutter speed is really 16s, so with that shutter speed the interval has to be 17s, and that a 30s exposure is really 32s so the interval has to be 33s — that’s true of all cameras. I would upgrade to M3 and above. One supplier of filter-modified cameras, Spencer’s Camera, also refuses to modify Sonys, because this glow renders them poor choices for filter modification, for those wanting cameras with deeper red sensitivity. Your cameras are getting worse for astrophotography while Sony’s are getting better. An example is the Laowa 15mm f/2 I used for some of the testing. I’m not here to knock Sony, in fact I shoot with one, using an A7R for my astro work because of this issue. Sony’s A7III camera has enjoyed rave reviews since its introduction earlier in 2018. All images are equally well exposed. Cheers! • The a7III lacks any internal intervalometer or ability to add one via an app. I am very impressed! In images taken at the same time with other cameras not accused of star eating, the Sony showed just as many faint stars as the competitors. This allows the Live View image to reflect the camera settings in use, better simulating the actual exposure, even without Bright Monitoring on. But this is a tough call. Obviously, anything will be better at this stage, but I have to say, this info has made me a lot more confident in sticking with Sony as I wasn’t keen on buying into a new lens system. Thank you very much for the in-depth review. I currently have an a7RII but have been considering the a7III, in part because I had read some things that seemed to indicate that it had better low light noise properties. I’m really on the fence on whether to get this camera. Noise at typical astrophoto ISO speeds – 800 to 6400 – were about equal to the four-year-old Nikon D750. In a mirrorless, the camera remains in “live view” all the time, with the sensor always feeding a live image to either or both the rear LCD screen and electronic viewfinder (EVF).
