So far everything is working as expected. Some lucky coincidence of adapter/lens/whatever having a suitable resonance frequency (on this particular implementation of the mount), so that all the energy of vibrations goes into a mode which does not affect the quality of the photo? Even if [Silent Shooting] is set to [On], it will not be completely silent. And two readers from UK confirmed that they will get their A7rII preorder from Wex UK on July 30 already! The a7RIII takes about 1/15 second to do the scan, so we’re going backwards here, thanks to the higher pixel count of the a7RIV. May it be Excellent stuff, Jim. Any photo editing software will damage this data. While most of them only offer an “electronic first curtain shutter” the A7s(II) and and A7rII even offer a completely silent, purely electronic shutter. Although Sony said that they increased the damping of the a7RII shutter over that of the a7R (and I have no reason to disbelieve them) with a long lens like this it doesn’t make much difference. You’ll notice that there has been a gap in my nearly-daily postings, and it’s not for lack of trying. Brace yourself. Le Sony A7R II est donc le premier COI Sony à enregistrer en 4K Télé (3 840 x 2 160 px) sur carte en XAVC-S. Il intègre également le format XAVC-S pour l'enregistrement HDTV 1080. The a7RIII has a silent shutter mode. The first was just a dumb move on my part: I accidentally left IBIS on in both cameras, even though they were mounted on a tripod. This is because the side-to-side vibrations take longer to die away, and all but the first shots are affected by the shots that came before, and mostly by the shot that came immediately before. “ The shutter unit is suspended with five springs so they act as a shock absorber when the shutter is pressed. First, I’ll drag you through the protocol. Hi guys, so I just got the Sony a7rii from KEH that I posted about earlier this week. An aside: I’m curious if you notice any measurable image degradation with the variable neutral density Heliopan 77mm filter. 0" 921. That EFCS line appears too good to be true, but I double-checked the data. There are  two possible reasons, and they both probably play a part. Be among the first to get the latest Sony news in your inbox. Using a remote release and A exposure mode, I made 16 exposures about 1 second apart at each setting with the light adjusted to give me shutter speeds of. But hey, there is no sun there so let them enjoy the camera as first :) The a7RIV lines are better because, due to its finer pitch, the camera has a smaller pixel aperture. Both the Sony A7iii and Sony A9 / A9ii offer a silent / electronic shutter. When running silent, the mechanical shutter is open and the sensor does all the work. Not much difference between silent shutter and EFCS. Required fields are marked *. Other camera models . With EFCS, there’s less vibration because the camera doesn’t have to wind and release the shutter just before the exposure. Photography wins -- most of the time. Unless the motor is suspended with the shutter, any spring system isn’t going to help with that. I went over the data several times, and double checked the EXIF information to make sure the cameras were set up the way I thought they were, and reran Imatest on another horizontal edge, but I didn’t find anything untoward. Not until you get to very high attenuation. Bryn, Jim, Or is it simply muffling the transmission of the shock to the photographer’s ears? First, the second curtain itself induces vibration. I suspect it’s because the a7RII drops to 12 bit precision in silent shutter mode and the read noise picks up. How to Set Up Silent Shutter Mode on Your Sony a6500. And I don’t usually — with one exception that I can think of when I thought I had a bad copy of the CO 60/4 macro and rented another copy from Roger at LensRentals — rent or borrow equipment, because I don’t like to feel rushed when I’m testing gear. This is one in a series of posts on the Sony alpha 7 R Mark IV (aka a7RIV). This lens doesn’t appear to be as sharp as the 180/3.4. In my first run of tests, I ran into two serious issues, either one of which would have made me have to throw out all the data and start over. Sony a7R II Silent Shooting was possible because data streams off the a7R II Back-Illuminated Sensor 3.5 times faster than previous Sony sensors. How come? IBIS stiffness when not engaged? So I took some pictures using RAW, uncompressed, silent shutter mode and no flash. Setting up silent shutter on your a6500 is very simple to do. Silent Shooting is a camera feature that allows you to shoot images without the sound created by the mechanical shutter. (Leica). Third, in the testing that Mike Collette performed on the a7R, the main source of the vibration came not from the release of the shutter curtains, but by the winding of the shutter, which occurs after the shutter release is pressed in mechanical shutter mode, but (obviously) before the first curtain is released. The dark blue line is for the mechanical shutter, and the blue dots are the measured points.The mechanical shutter curve behaves pretty much as expected. Unfortunately, in many cases, the shot-to-shot scatter due to autofocus errors was at least as large as the effect I was trying to measure, making it hard to make sense of the results. Here’s the mechanical shutter data for both cameras: The heavy lines are the means of the MTF50s. What’s wrong with conventional lens screening? If you own the very laud Sony A7r than you may be really interested how much more silent the new A7rII shutter is. At low speeds, most of the vibrations have damped down during most of the time the shutter is open, so there’s not much blur. I thought you were tough. How does the GFX100 compare to the GFX50? ONLY ORIGINAL JPG or ARW files STRAIGHT from the camera will work. The effect of this countermeasure is astounding. What’s wrong with conventional lens screening? In the United States and Canada, artificial light has a frequency of 60hz. Fuji X-H1 vs. Fuji X-T3? You want the good news or the bad news first? In order to get 13 bits, I have to avoid bulb, and continuous drive, is there anything else I have to avoid? With electronic shutter, there’s the lease vibration of all because no part of the shutter assembly moves either before, durning, or after the shutter is released. In the next picture, which is the same graph except the data is from the a7RIII exposures, you’ll see a situation where that isn’t true at all. The first series of images was made with the camera in landscape orientation. Jim – on the A7RIV, does silent shooting/silent shutter reduce bit depth in single shot mode or does it remain at 14 bits? Silent shooting with the Sony A7R III is impressively, well, silent. First off, I don’t test cameras and other equipment that I have no interest in using. This tool will provide the number of shutter actuations that the camera has made up to the file in question. Even if a quantization error were introduced it would look like additional noise in the Edge Spread Function, which would show up as modulation of the results: but here the average is consistently lower. Second, on most MILC cameras these days, shutter shock is mostly academic, since EFCS is available. Granted it is used, but is that normal? When shooting still images using the [ Silent Shooting] function with low ISO sensitivity, if you point the camera at a very bright light source, high intensity areas on the monitor may be recorded in darker tones. The shock absorber also contributes to quietness of the shutter.”. That’s because the bulk of the motion imparted to a tripod mounted mirrorless camera with no added delay between winding the shutter and firing the first curtain comes from the winding action, not the motion of the first curtain. I think the main reason is that I couldn’t get far enough away from the target. Second, the vibrations from the exposure one second before the current one may not have completely died away. ... Press the MENU button → (Shooting) → Shutter/Silent → Shutter Type → Electronic Shutter. Banding with silent shutter on Sony A7riii at 1/640 Artificial light is not actually “constant” but has a frequency. That is especially true for a big lens which has a relatively low resonant frequency compared to a small one. Since you do have a GFX100, it would be interesting to see how the data plots out. With the a7RII, i used the mechanical shutter for one set of images, the electronic first-curtain shutter (EFCS)  for another, and the all-electronic — silent — shutter for a third. I put the Leica 280mm f/4 Apo-Telyt-R on both the a7R and a7RII, mounted the lens collar to an Arca Swiss C1 head on a set of RRS TVC-43 legs, set the whole thing on a vinyl tile over 6 inch concrete floor, and made some slanted edge photographs at various shutter speeds. Manual focusing wide open, then lens set to f/6.9 (halfway between f/5.6 and f/8). It’s real close, but the EFCS actually appears to be a hair better than the silent shutter. Does an audibly quiet shutter translate into less shutter shock? Fortunately, there was a workaround: turn off live view before tripping the shutter. How fast is the Sony a7RIV silent shutter? Out of concern for focus shift during 500-shot series, I put away the 135 mm f/2.8 Batis native E-mount lens, and took out a 135 mm /f2 Zeiss Apo-Sonnar F-mount lens and a Kipon F-to-E adapter. Restrictions when using the Silent Shooting mode Silent Shooting is available when the Mode dial is set to P, A, S or M. At high shutter speeds, there is little blur because the camera doesn’t have much time to move while the shutter is open.
