Uncompressed Raws are 47 Mb in size; Compressed Raws are 24 Mb. With its good shadow details, you have to apply less shadow recovery in post-processing, which does keep noise down. An alternative would be an LCD screen that was touch sensitive. As versatile as a mirrorless camera is for lens choice, making use of that versatility requires buying the right lens adapter(s). I put this on C1. SONY TILTING SCREEN It tilts up and down but does not flip out as with the Canon 6D MkII’s. It’ll be ok at 3200. To reduce battery drain it is possible to turn off the EVF completely – I find I never use it at night – and to turn off the LCD display when shooting, though the latter is an option you have to activate to add to the Display button’s various modes.Â, The downside is that when shooting is underway you get no reassuring indication anything is happening, except for a brief LED flash when an image is written to a card. Â. The other Live View function that works well, but also needs assigning to a C button is the Camera Settings 1 > Focus Magnifier. To the eye, the Sony and Nikon look very similar for noise levels, just as in the moonlit scene. I believe the Sony A7iii is a best camera for wedding photography now in 2019. 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. ISO Invariance  Thanks for reading! This is from a thin metal mask in front of the sensor. Stars are visible to the same limiting magnitude and close double stars are just as well resolved across all exposures. Reddit's most popular camera brand-specific subreddit! Camera Settings for Astrophotography There are certain rules that you must abide for capturing the space and the Milky way. 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. Here are some other Sony A7III features I found of value for astrophotography, and for operating the camera at night. The four C buttons can be programmed for oft-used functions, making them easy to access at night. Looks like you're using new Reddit on an old browser. 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. Due to limitations set by Sony, controlling one of their cameras with an external controller can be problematic.Â, Devices that trigger only the shutter should be fine. Again, here I show only the Sony and Nikon, the two “ISO invariant” cameras. This allows the Live View image to reflect the camera settings in use, better simulating the actual exposure, even without Bright Monitoring on. In January I embarked on a personal challenge to spend #100NightsUnderTheStars . 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. The Sony A7III offers a choice of shooting Uncompressed or Compressed Raw files. In particular, many stars look green, from the dominance of green-filtered photosites on Bayer-array sensors. I hope you found these latest tests of interest. In my testing I compared the Sony A7III to two competitive DSLRs, the Canon 6D MkII and Nikon D750. Indeed, at slower ISOs and longer exposures, more stars are visible. I know … people shoot dark frames separately for subtracting later in processing. I use a $50 Vello unit, and it works very well. Bright Monitoring does not appear in any of the in-camera menus you can scroll through, so you won’t stumble across it. ISO INVARIANCE CLOSE-UP – A closeup of the scene shows the ISO variant Canon exhibited more noise and magenta discoloration in the +4 EV boosted image. STAR EATER DEEP-SKY #2 – Another example with 4-minute exposures again demonstrates no problems recording faint stars. I shot with the Sony A7III on Single shot drive mode, on Continuous Low drive mode (with the camera controlling the shutter speed in both cases), and a set with the Sony on Bulb and the shutter speed set by an external Vello intervalometer. Lots of menu options to go through, with different functions thrown under random menus. There are many people testifying that the Sony a7III is a great choice for beginners due to its versatility and ease of use. STAR EATER SERIES at 400% – This is the same series as above but now blown up 400% to better reveal the very subtle change in pixel-level sharpness as exposure lengthened from 3.2 to 4 seconds. I expected the new BSI-equipped Sony to better the Nikon by about a stop. The ones taken with LENR on show fewer hot pixels. Sony α7R III, Sony 16-35mm f/2.8 G Master lens. Camera Settings 1 > Peaking Setting. Between 3.2s and 4s a very slight one-pixel-level softening does kick in, reducing noise and very slightly blurring stars. taken at room temperature with and without Long Exposure Noise Reduction. While these might add glows to long exposure images, if they could be designed not to do that (i.e. The A73 has the following shooting modes: Intelligent Auto: All settings are handled by the camera and it’ll even try to identify the scene from the list of 11 scenes (which we’ll go through in a bit). UNCOMPRESSED vs. COMPRESSED at -4EV – The same scene but now underexposed by 4 stops and boosted by +4 EV later shows greater differences. COMPACT CAMERA and LENS – The Sony A7III with the compact but fast Laowa Venus Optics 15mm f/2 lens. I was shooting on a Canon 70D & Sigma 18-35 f1.8 and just switched to the Sony A7R III & Sony 16-35 f2.8GM for Astrophotography but unfortunately, I don’t find the combo sensible enough. 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. Hurray! For the price, the Sony a7III is one of the best values on the market. Two other functions are useful for Live View: In all, the Sony provides superb, if well-hidden, Live View options that make accurately framing and focusing a nightscape or time-lapse scene a joy. I like its image stacking options, which can help alleviate the noise and artifacts in still images, but aren’t practical for time-lapses. But if the Sony had a built-in intervalometer…! This might be an aid, or an annoyance. The higher noise of the Canon is visually obvious, but I’d say the Sony A7III and Nikon D750 are pretty equal visually for noise, despite the numbers. Surprise! (True 4K is actually 4096 x 2160 pixels.). Sensor Illumination Uniformity Here I compare all three cameras for this effect in two-minute tracked exposures taken with Long Exposure Noise Reduction (i.e. SONY LIVE VIEW – The Sony A7III’s excellent Live View screen display. The Nikon had the Sigma 14mm Art lens; the Canon and Sony used the same Rokinon 14mm SP lens. Well, almost. So points to Sony here. Today we’re going to walk you through how I set up my Sony A7iii for video. I trust you’ll find the review of value. All with the Laowa 15mm lens and Sony A7III at ISO 3200. Turning this ON superimposes a shimmering effect on parts of an image judged in focus. The design lends itself to video shooting, with many mirrorless cameras offering 4K as standard, while often in DSLRs only high-end models do. The Star Eater is gone. The Canon is more neutral and natural. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. You can find out more about John on his website and follow his adventures on YouTube. https://www.youtube.com/watch?v=en4eeK33UoE This should help you! For elimination of hot pixels from thermal noise I prefer to use Long Exposure Noise Reduction when possible for nightscape and deep-sky images, especially on warm summer nights. All images are equally well exposed. In Movie Mode ISO speeds go up to ISO 102,400, but are pretty noisy, if unusable at such speeds. To me, the star eater effect on the Sony A7III is a non-issue. Sony for wedding photography Here’s my opinion. This feature is little known and utilized, and only Canon full-frame cameras offer it. Your cameras are getting worse for astrophotography while Sony’s are getting better.Â. 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. Those underexposed images were then boosted later in processing (in Adobe Camera Raw) by the required Exposure Value to equalize the image brightness. The Sony a7III proves itself as a great astrophotography camera and general all-rounder. All images are well-exposed, for tracked and guided 4-minute exposures. Go figure! Lenses developed natively for mirrorless models can be smaller and lighter. Introduction The Sony … Nikons don’t have this, not even the D810a, and not Sonys.Â, The Sony’s buttons are not illuminated. We shoot everything on manual. In most shooting situations, I found using LENR provided the overriding positive benefit of reducing hot pixels. The Sony A7iii is a powerhouse but to unlock its full power you need to be able to get into the settings. 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. Now, let’s dive into some of the software settings and capabilities of the Sony A7III as quick as we can. Now it’s time to get deep into those camera menus and show you how I setup my camera to shoot surf and ocean images. Keep in mind, these are vastly underexposed images. In Continuous mode, I think the effect is still there but maybe a little less. 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. Therefore, I am looking for another lens and come across the Sony … Noise This movie tutorial covers the camera settings I use for capturing shallow depth of field portraits using an 85mm prime lens or Pro Zoom. Hey Guys, I just got my Sony A7III with the 24-105mm G lens. All cameras show an equal number of stars recorded. An example is in a 4K video I shot on May 6, 2018 of an usual aurora known as “STEVE.”. Fair enough. The Nikon seems to discolor stars only when LENR is applied. You can see the Milky Way! In shots on Bulb controlled by the External Timer, maybe the stars at 4 seconds are a little sharper still. LENR also added a background level of fine noise. New comments cannot be posted and votes cannot be cast. Aperture priority mode, selecting aperture based on desired depth of field. UNCOMPRESSED vs. COMPRESSED – Here I compare any image degradation from using compressed vs. uncompressed Raws, and from employing Long Exposure Noise Reduction. 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. Sony doesn’t have an “a” model mirrorless. Conclusion and Verdict. 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). I just got my Sony A7III with the 24-105mm G lens. April 12, 2020. great astro photography source for what you are looking for, *not specific to your camera, just astro in general. INTERVALOMETER – For time-lapses, the Sony must be used with an external intervalometer like this Vello unit. The 2008-vintage 5D MkII had a 5-frame buffer! This is excellent performance on par with the DSLRs I use. Even if you could get a mirrorless camera to focus without a lens adapter to add the extra spacing, the image quality across the field might be compromised on many telescopes.
