I know â¦ people shoot dark frames separately for subtracting later in processing. Instead, you have to go to the Camera Settings 2 page, then select Still ImageâCustom Key. What’s up guys, Sagi here and welcome to another Tech Gear Talk. 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. The resulting values and graph show the Sony actually measuredÂ worseÂ for noise than the Nikon at each high ISO speed, 3200 to 12800, though with both performing much better than the Canon. But to develop all the images from Sony, Nikon, and Canon equally for comparisons, ACR is the best choice.Â. Dark frame subtraction using Long Exposure Noise Reduction removed most â but not all â hot pixels from thermal noise.Â, Live View Focusing and Framing I use a $50 Vello unit, and it works very well. You do get the benefit of reduced hot pixels in shadows, especially on a warm night like this was. With the Metering Mode setting, you specify which area of the frame the camera should work on. Most DSLRs do not offer this, but the Sonyâs 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. Best Standard Prime Lenses for Sony a7 III Sony Zeiss FE 35mm f/1.4 Distagon T* ($1,598): Fast, sharp, and loaded with the latest technology, the FE 35mm f/1.4 ZA offers outstanding optical performance in a versatile 35mm focal length. STAR EATER DEEP-SKY #2 –Â Another example with 4-minute exposures again demonstrates no problems recording faint stars. Sony advises that when using LENR Raw images are recorded with only 12-bit depth, not 14-bit. In Single drive mode, stars and noise soften ever so slightly at 4 seconds and higher. I was using the wired Vello intervalometer. SONY LIVE VIEW –Â The Sony A7IIIâs excellent Live View screen display. The Star Eater is gone. A built-in intervalometer is not essential, since in time-lapse shooting we often use external controllers anyway. SONY FIELD ILLUMINATION #2 –Â Another example taken in twilight to accentuate frame illumination shows the same shadow vignetting and the slight magenta amp glow at the left. In Movie Mode ISO speeds go up to ISO 102,400, but are pretty noisy, if unusable at such speeds. The Sony exhibited good â though not great â âISO invariantâ performance. I am very impressed! He fell in love with photography in 2013 when he got a camera as a birthday present. Aperture priority mode, selecting aperture based on desired depth of field. 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. Coupled with a fast f/1.4 to f/2 lens, the slow shutter speed allows real-time aurora shooting at âonlyâ ISO 6400 to 12,800, for quite acceptable levels of noise. Turn on LENR and it is possible to shoot three (with the 6D MkII) or four (with the 6D) Raw images in quick succession even with LENR turned on. To me, the star eater effect on the Sony A7III is a non-issue. This is really pixel peeping at 400%. It did not. This article was also published here and shared with permission. SONY REAL-WORLD LENR COMPARISON –Â A real-world example with the Sony, with a properly exposed nightscape, shows that the ill effects of using LENR donât show up under normal processing. SENSOR CLOSE-UP showing intruding mask edges. My Sony A7 III Camera Settings for Portrait Photography Most of the portraits you see on this site were shot with a Sony A7 III camera. The Sony doesnât do quite as well as the Canon 6D MkII. These were then boosted in Adobe Camera Raw by 2 and 4 stops in Exposure Value (EV) to compensate. Turning on LENR did eliminate most hot pixels in long exposures, but not all. The Canon is free of any such issue â stars are naturally colored whether LENR dark frames are applied or not. Again, the Sony records just as many stars as the Nikon. I think itâs a great camera for both astrophoto stills and video. 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. Today we’re going to walk you through how I set up my Sony A7iii for video. As versatile as a mirrorless camera is for lens choice, making use of that versatility requires buying the right lens adapter(s). I did not see any significant âstar eatingâ in any long exposures even up to the 4 minutes I used for some deep-sky shots. COMPACT CAMERA and LENS –Â The Sony A7III with the compact but fast Laowa Venus Optics 15mm f/2 lens. Give me a Canon full-frame any day for prime-focus deep-sky shooting.Â, Itâs just a pity the 6D MkII has only a 3-frame buffer when using LENR. The disadvantage is that full-time live view draws more power, with mirrorless cameras notorious for being battery hungry. While it does have a 1 frame-per-second movie mode in its âSlow-and Quickâ functions, thatâs not sufficient for night time-lapses, plus S&Q mode only works with HD movies, not 4K. WITH METABONES CANON ADAPTER –Â The MetaBones Canon EF-to-Sony E mount adapter transfers lens data and allows auto focus to function. In new models, Sony now offers the option of a final âMy Menuâ page which you can populate with often-used functions from the other 35 pages of menu commands! 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. An alternative would be an LCD screen that was touch sensitive. Bright Monitoring does not appear in any of the in-camera menus you can scroll through, so you wonât stumble across it.
