So am I correct in assuming that about 2000 or so of the shots that require 256 blended shots, max out the expected life expectancy of the sensor in the A7rll ?

' max out the expected life expectancy of the sensor' ?
News to me a sensor has a lifespan. I suppose everything does.
I would have thought more of the shutter eh?
Please tell me more. I've got some really aging bodies, a G1X comes to mind...it is well
over 500,000 clicks and no evidence at all the sensor is showing any signs of slowing down.

Hi Fred, happy new year. Off the topic, I saw that you sold your Canon T&S 17mm and 24mm which you used on your A7R to create some really impressive images. Just curious if you replaced them with other lenses for your Sony bodies? I am thinking of tipping my toe in the T&S water for architecture shots.
Decided to download the Smoothing app and give it a test try for the sake of comparison. The test image is nothing special, just a pond in front of my house. Not as windy as yesterday, but still some water movement. I used a Canon EF 24-70/2.8L set at 50mm focal length. Base exposure info was 1/60 at f/11, ISO 100. I chose this lens simply because my Singh-Ray variable ND has the same filter size so I wouldn't need to use any step rings with a smaller lens. First image is at base exposure; second image is using the smoothing app at 8 stops (256 images); final is using the Singh-Ray VND set to 8 stops. All in all, the results with the app and VND seem to be on par, although it looks like I didn't quite dial-in the full 8 stops with the filter as evidenced by the ripples in the water at the far side of the pond. The obvious advantage to the VND is one shot and you're done, with minimal wear and tear on your shutter. The only thing I can't figure is that even though my file type is set to RAW, the combined image through the app is importing into LR as a JPEG. Why?
There's no RAW only output.
The app can output RAW+Jpeg though.

Thanks...found the RAW+jpeg option further into the menus. That's a typical fault of an engineer...don't read the instructions...just jump into it and see what happens.
Looks interesting but I'm not that keen on the excessive shutter actuations required for a single image. If used sparingly I guess it's ok, but if you are heavy into long exposures, I'd rather go the ND route.

Yep, that's my line of thinking too. The exposure with the VND took all of two seconds, while the smoothing app needed 4-5 minutes for the 256 exposures. In a pinch, I'd use the app but in general I'll stick with the filter. As long as you're using a high quality filter, color cast issues shouldn't be a problem. I've been using the VND for several years, as well as a Lee big stopper (10-stops of ND) without any obvious issues. The app is interesting, though.
I think the best solution, in terms of shooting time, freedom from color cast, and reduced wear/tear on the shutter (for those whom its a concern) would be a blend between using the app (or just PS), and a 3 stop ND; at least for the typical 3-4 minute type of long exposure I like doing.
Stacking/blending 30 or so 2-3 second exposures avoids the color cast issues I run into with my 9 and 10 stop ND's, I don't need to stop down quite as much either so less issues with diffraction, and I don't need to take several hundred hundreds which would be required without a filter at all.
If you've got an internal timer on your camera, you can set it to do this pretty easily, and while you'd still have to do it in post instead of the app, it does allow a new technique for those who don't have a compatible Sony model.
I have a 3 stop and a 10 stop ND filter from Hoya. The 3 stop shows no color cast. The 10 stop has a distinct cyan cast, which creates difficulties with shots that contain blue sky and/or water. Not a good thing, and Hoya is one of the best.
I like the idea of using the three stop filter and doing a 32 shot blend. That's an 8 stop equivalency without the color cast.
By the time the shutter dies, your camera will most likely be obsolete anyways...Even if you want to replace the shutter, the cost will be about $250. I would not worry about it.
Today I went to the coast and shot with the A7RII and Rx1R II. I was using both ND filters and the sky app. On the RX1R--- the files were only saved as jpg. My non sky app images were saved as both-- that is what i had it set to. Not sure why the difference between the two cameras
?
