sony a7iii astrophotography settings

The compressed images appear identical to the uncompressed files for noise and star content. Compact size and lighter weight, yet offering all the image quality of a full-frame DSLR. Camera Settings 2 > Live View Display > Setting Effect ON. The ones taken with LENR on show fewer hot pixels. MF Assist: On – a great feature that automatically zooms in when you move the focus ring in manual focus mode. Whether you are pursuing DSLR telescope astrophotography or simple using an astrophotography tripod , there are certain tricks and techniques you must follow. To me, the star eater effect on the Sony A7III is a non-issue. MILKY WAY and PLANETS With the Sony A7III and Laowa 15mm lens at f/2 for a stack of 4 exposures for the ground to smooth noise and one exposure for the sky, all 30 seconds at ISO 3200. When shooting deep-sky objects, particularly red nebulas, we like a camera to have a less aggressive infrared cutoff filter, to pick up as much of the deep red Hydrogen-Alpha emission line as possible. That includes simple intervalometers like the Vello, the Syrp Genie Mini panning unit, and the Dynamic Perception and Rhino sliders, to name devices I use. This feature is little known and utilized, and only Canon full-frame cameras offer it. This lens balances nicely when paired with the Sony A7III and has a sturdy feel. This allows the Live View image to reflect the camera settings in use, better simulating the actual exposure, even without Bright Monitoring on. STAR EATER DEEP-SKY #1 – Tracked deep-sky images through a telescope using 4-minute exposures show the Sony A7III recording an equal number of faint stars as the Canon 6D MkII. Seeing is believing and I am confident that when the word gets around of how TRULY amazing this Gmaster 24mm f1.4 is, it will be called the holy grail of lenses for astrophotography. You can take full advantage of wide-angle lenses, great for auroras. This isn’t a huge detriment, as anyone who really wants to go after deep nebulosity must use a “filter-modified” camera anyway. But … when well exposed, such as in tracked deep-sky images, the 6D MkII performs well. they turn off during exposures), lit buttons would be very handy at night.Â. Why would that be? My current gear list; Nikon D5300. 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. 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? At 24 fps videos are full-frame with no cropping. Image quality was just fine. The Sony showed some slight edge-of-frame shadowing from the mask in front of the sensor, as well as a weak purple amp glow. An example is the Laowa 15mm f/2 I used for some of the testing. Good luck and fingers crossed for clear skies! Give me a Canon full-frame any day for prime-focus deep-sky shooting.Â, It’s just a pity the 6D MkII has only a 3-frame buffer when using LENR. So beware! An issue that, to me, has a more serious effect on star quality is the propensity of the Sony, and to some extent the Nikon, to render tiny stars as brightly colored points, unrealistically so. This might be a contributing factor. https://www.youtube.com/watch?v=en4eeK33UoE This should help you! I rate the Sony excellent for nightscape imaging and for real-time aurora videos. As with Sony’s other popular Alpha 7 and 9 series cameras, the new Alpha 7III is a full-frame mirrorless camera, a class of camera Canon and Nikon have yet to offer, though models are rumoured or promised. Is Sony a7III good for beginners? I would assume not, but not having an a7s (either Mark I or II) to test I can’t say for sure. This might be useful for long shoots, though likely as not that same USB port will be needed for an intervalometer or motion control device. But this is a tough call. Here are some other Sony A7III features I found of value for astrophotography, and for operating the camera at night. UNCOMPRESSED vs. COMPRESSED at -4EV – The same scene but now underexposed by 4 stops and boosted by +4 EV later shows greater differences. Sony A7 III, A7R III, A9 Metering Settings. With a full frame sensor and ISO 409600, is it the best low light camera out there? ISO Invariance  When used with the Genie Mini (below) the Sony fired at only every other pulse if it was in Single shot mode, an oddity of Sony’s firmware. This is a blow-up of the lower corner of the frame, as indicated. One question though, I set Memory 1 to your landscape settings and Memory 2 to Action. Sony α7R III, Sony 16-35mm f/2.8 G Master lens. Camera Settings 1 / Exposure1 (page 9/14) Metering is a function that allow your camera to measure the correct exposure based on the amount of light that is coming through the lens. These are all uncompressed 14-bit Raw files. Its red sensitivity is not bad, but its lack of a light frame buffer results a less productive imaging cycle when using LENR on deep-sky shooting. SONY FIELD ILLUMINATION #2 – Another example taken in twilight to accentuate frame illumination shows the same shadow vignetting and the slight magenta amp glow at the left. New comments cannot be posted and votes cannot be cast. the lens cap on!) CAMERA TRIO – The Sony A7III, Nikon D750, and Canon 6D Mark II. These were then boosted in Adobe Camera Raw by 2 and 4 stops in Exposure Value (EV) to compensate. 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. The Sony would perform better for noise under dark sky conditions, at high ISOs, rather than the moonlit scene above. Thus my Good rating for nightscapes but Fair rating for time-lapses. Tokina 11-16mm f2.8 ATX PRO DX II. The Sony A7 III RAW bit depth is 14-bit when taking pictures in single shooting mode, and this is also valid for the A7R IV, A7 II and A9 series. For the price, the Sony a7III is one of the best values on the market. Stars are visible to the same limiting magnitude and close double stars are just as well resolved across all exposures. I haven’t seen amp glows in cameras (at least in the DSLRs I’ve used) for a number of years, so seeing it in the new Sony A7III was another surprise. I was using the wired Vello intervalometer. In the menu options that appear you can now scroll to one called Bright Monitoring. You can see her work on Flickr, Behance and her Facebook page. Going to be very hard to get good astro at f4. Really Canon? STAR EATER DEEP-SKY #2 – Another example with 4-minute exposures again demonstrates no problems recording faint stars. 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). This is all with Raws developed with Adobe Camera Raw. Hey Guys, I just got my Sony A7III with the 24-105mm G lens. An alternative would be an LCD screen that was touch sensitive. SONY WITH THE SYRP GENIE MINI – The Sony A7III worked well with the Syrp Genie Mini motion controller with the right shutter cable but only when placed in Continuous mode. The Star Eater is gone. The Sony A7III offers a choice of shooting Uncompressed or Compressed Raw files. In the meantime, Sony commands the full-frame mirrorless market. UNCOMPRESSED vs. COMPRESSED DEEP-SKY – A real-world deep-sky example shows the same comparison. Overall Recommendations The 500/focal length rule for exposition time is also usually working to avoid star trails, but it can wield different results depending on how far from the Polar star you are actually aiming. Noise at typical astrophoto ISO speeds – 800 to 6400 – were about equal to the four-year-old Nikon D750.Â, That was a bit surprising. This is with the EVF and rear LCD Display OFF, and the camera in Airplane mode to turn off wireless functions to further conserve battery power. How tough would it be to add it, Sony? I used the Metabones Canon-to-Sony adapter when attaching the Sony to my telescopes using my existing Canon telescope adapters. This was true whether I was shooting compressed or uncompressed Raws, with or without Long Exposure Noise Reduction. SONY WITH AND WITHOUT LENR – These are 4-minute exposures of dark frames (i.e. great astro photography source for what you are looking for, *not specific to your camera, just astro in general. Here are 7 astrophotography tips that have helped me capture hundreds of images of the night sky including stars, the Milky Way, Galaxies, Nebulae and more. This emphasizes just how good the Nikon D750 is.Â, Nevertheless, noise performance of the Sony A7III was still excellent, with both the Sony and Nikon handily outperforming the Canon 6D MkII, with its slightly smaller pixels, by about a stop in noise levels.Â, NOTE: I performed all Raw developing with Adobe Camera Raw v10.3. However, I emphasize that the noise increase from using LENR with the Sony was visible only when severely boosting underexposed images in processing. So points to Sony here. 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). In Single drive mode, stars and noise soften ever so slightly at 4 seconds and higher. Thanks for reading! The 2008-vintage 5D MkII had a 5-frame buffer! You can see the Milky Way! Indeed, at slower ISOs and longer exposures, more stars are visible. Page 2 of 2 - Sony a7III Settings for Astrophotography - posted in DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging: 3 (Custom) Note: … This is where the Sony’s Backside Illuminated sensor with presumably higher quantum efficiency in gathering photons might be providing the advantage. NOISE AT ISO 3200 – At ISO 3200, a common nightscape ISO speed, all three cameras performed well in this moonlit scene. The Sony A7III is a superb camera for still and time-lapse nightscape shooting, and excellent for real-time aurora videos. Not a very good lens for astro tbh. Sony for wedding photography Here’s my opinion. Released five years after the original A7, the Sony A7III marks the third generation of Sony’s ‘entry’ level full-frame mirrorless camera series. When using a slow shutter speed with ND filter for waterfalls on a Sony mirrorless camera, like the Sony A7riii or A7iii, don’t forget these settings: Use a tripod; ND filter attached to lens, between a 6 stop and a 10 stop filter. Instead, I saw a slight shadowing at the top and bottom edges but just at the corners. The images shown here were shot at lower ISOs to underexposure the dark scene by 2 to 4 stops or EV. When shooting in continuous mode, the bit depth drops to 12-bit. Also the A7iii can handle higher ISO. Turning this ON superimposes a shimmering effect on parts of an image judged in focus. The Canon is free of any such issue – stars are naturally colored whether LENR dark frames are applied or not. Note the size difference. No luminance noise reduction was applied to these images in processing. Since publishing the first results a number of people commented with suggestions for further testing, to check claims that: For the additional tests, I shot all images within a 3-hour span on the night of June 5/6, using the Sony A7III, Nikon D750, and Canon 6D MkII, with the respective lenses: the Laowa 15mm lens at f/2, the Sigma 14mm Art at f/2, and the Rokinon 14mm SP at f/2.5. in-camera dark frame subtraction) off and on. This is from a thin metal mask in front of the sensor. This Sony lens review intends to look for what can be classed at the best lens for Sony A7iii astrophotography. While the Sony has a Bulb setting there is no Bulb Timer as there is with the Canon. LENR also added a background level of fine noise. It controls the Sony through the camera’s Multi USB port. Therefore, I am looking for another lens and come across the Sony … Dark Frames  Again, here I show only the Sony and Nikon, the two “ISO invariant” cameras. ADAPTING TO A TELESCOPE – The MetaBones adapter, as will other brands, adds the correct lens flange to sensor distance for telescope field flatteners to work best. In Continuous mode, I think the effect is still there but maybe a little less. I feel that in the A7III the Star Eater has been largely vanquished. But the Nikon did show more image artifacts in the “odd-numbered” ISOs of 640 and 500. I love it! This is good news, as astrophotography requires fast, high-quality lenses, and the Sony allows more choices. This makes it so easy to frame nightscapes and deep-sky fields. 20-sec., f/2.8, ISO 10,000 Shoot RAW I always shoot astro in RAW as there really isn’t any good reason to shoot them in JPEG considering you will always need to do some post processing for the best final images. The camera itself can be used in a number of different settings such as dusk and dawn, and … Here’s another area where the new Sony A7III really shines. Based around an updated 24.2-megapixel back-illuminated full-frame sensor, the A7 III punches well above its weight with a rich feature including a 693 phase-detect autofocus system, 10 frames per second, internal 4k video, and silent operation. Excellent! The Canon shows a darker sky as its images were taken a few minutes later. Nevertheless, for the demands of nightscape and deep-sky shooting and processing, I suggest shooting Uncompressed Raws. The compressed image shows more noise and discoloration, and the images taken with LENR on, while eliminating hot pixels, show more random luminance noise. It’ll be ok at 3200. STAR TRAILS and AURORA With the Laowa 15mm lens and Sony A7III, for 155 exposures, all 20 seconds at f/2.8 and at ISO 800, and taken as part of a 360-frame time-lapse. Here I compare all three cameras for this effect in two-minute tracked exposures taken with Long Exposure Noise Reduction (i.e. All cameras show an equal number of stars recorded. ISO INVARIANCE COMPARISON – Here I shot all three cameras at ISO 6400 for a correct exposure for the scene, and also at ISO 1600 and ISO 400, for images 2 and 4 stops underexposed respectively. While the 6D MkII has HD video, it is incapable of any low-light video work. Coupled with a fast f/1.4 to f/2 lens, the slow shutter speed allows real-time aurora shooting at “only” ISO 6400 to 12,800, for quite acceptable levels of noise. These have had exposure and contrast increased to exaggerate the differences. His work has been commissioned by Adobe, Microsoft, Nike, Samsung, Dell, AVS, Starbucks, Viber, and WeWork. The Nikon can do so after LENR is applied. See http://docs.view.tl/#camera-specific-notesÂ, With the Alpine Laboratories Radian2, exposure ramping is not possible with a Sony, only basic shutter triggering. I list it as just “good” for time-lapse work only because it will not be fully compatible with some motion controllers and rampers. As such, I would have expected a more uniformly illuminated sensor. The Canon 5D series also has this.Â, The dark frame kicks in and locks up the camera only after the series of “light frames” are taken. You can find out more about John on his website and follow his adventures on YouTube. NOISE AT ISO 6400 – At ISO 6400, the Canon begins to show excessive noise, about a stop worse than the Nikon and Sony. Again, the differences are in images vastly underexposed. Sony A7III Software. Posting to instagram). LUNAR CLOSE-UPS COMPARED – This trio compares closeups of the Moon taken with and without electronic front curtain shutter. NIKON WITH AND WITHOUT LENR – Dark frames taken with the Nikon D750 under the same circumstances and processed the same show none of the residual hot pixels and added background noise when LENR is employed. It may be more serious on other Sony alphas. The Sony begins to show more noise and now a magenta discoloration in the +3 and +4 EV images, similar to, but not as badly as does the ISO-variant Canon 6D MkII. Assign it to one of the hardware Custom C buttons. (See my test at https://amazingsky.net/2017/09/07/testing-the-canon-6d-mkii-for-deep-sky/), And its light-frame buffer is great for minimizing shooting time for a series of deep-sky images with in-camera LENR dark frames, which I find are the best for minimizing thermal noise. Surprise! Yet, just as many stars are recorded and are resolved, and at the lower ISOs/longer exposures more stars are visible because faint stars are not lost in the noise. In new models, Sony now offers the option of a final “My Menu” page which you can populate with often-used functions from the other 35 pages of menu commands! Turning on LENR did eliminate most hot pixels in long exposures, but not all. Well, almost. I did put all the high ISO images through the classic noise reduction program Noise Ninja to measure total Luminance and Chrominance noise, and included the Canon 6D MkII’s images. Very noticeable star trails so images really arent good for anything other than small posts like instagram. Which means higher iso. The design lends itself to video shooting, with many mirrorless cameras offering 4K as standard, while often in DSLRs only high-end models do. No luminance noise reduction was applied to these images. I hope you found these latest tests of interest. Fair enough. The Nikon had the Sigma 14mm Art lens; the Canon and Sony used the same Rokinon 14mm SP lens. High-Quality lenses, great for auroras select an area for auto focus or zooming up an image in playback f/1.8.
