On some Sony lenses, a part of the lens corrections is still applied even when turned off in the menu, AFAIK. Also, I think FE lenses are always in-camera corrected to achieve the desired T-stop. ...

It was a known problem with the first generation A7 and - to a much lesser degree - the A7II and maybe the A7RII. It's been fixed in any of the newer cameras. But - there's always a but - you can't ...

If you look closely (or push the contrast and exposure) you can see, that there are about the same number of spots in both images. But in the crop with the FE20, they are brighter. It looks to me ...

Your shutter has a hole and is likely to fail in the near future. Another example: https://www.dpreview.com/forums/thread/4351550

Have you tried to convert the files to DNG using pixelshift2dng? https://www.fastrawviewer.com/PixelShift2DNG It might produce different output than the Sony converter. Maybe those DNGs then work ...

The softness in the first shot looks like motion blur to me. Second and third look fine. I would make sure that (1) SteadyShot is turned on (2) You are holding the camera steady, ...

This discussion is getting quite heated, but there's really no reason why. That being said, your initial examples of the test charts appear crooked to me, because the camera was not aligned ...

No, the 10.9 refers to the strength class: https://en.wikipedia.org/wiki/Screw#Mechanical_classifications With your measures, this is most likely a custom M4 machine screw with length 13.5. In that ...

You can get Sony parts from https://sony.encompass.com/ . They are the official Sony service partner. You could also try one for those "soft shutter buttons" from eBay, which are simply glued on.

Yeah, these are all "tuning fork" type micro electromechanical (MEMS) gyros. An old example: [ J. Bernstein, S. Cho, A. T. King, A. Kourepenis, P. Maciel, and M. Weinberg, "A Micromachined ...

Maybe you could user PixelShift2DNG to avoid the Sony stacking software and see if this solves the profile problem? https://www.fastrawviewer.com/PixelShift2DNG

No, luckily you don't need two accelerometers. All the modern cameras use one-chip inertial measurement units (IMU's), which incorporate an accelerometer and a gyroscope. See this, for example: htt ...

The effect changes when you zoom, so it is clearly related to the optics. The fact that it does also appear in your closet means very little, as it may seem dark to your - but that only means it ...

Canon themselves state that they use diffraction here . Maybe a non-marketing, more honest description woulb be something along the lines of "refractvice optics with some additional, diffractive ...

Well, that would point to one of the following problems: (1) Lack of color resolution in the 8 bit JPEG (vs. 14 bit RAW and 16 bit TIFF)

You're mixing up different categories of words, here. All modern consumer cameras use CMOS sensors. The other common type is CCD sensors, which are not widely used anymore in consumer electronics. ...

First of all, you have a modified camera, so comparing with it introduces new variables. Second, these do not look like the usual cRAW artifacts, which are lines of (as far as I remember) 1 pixel ...

Yes and no. A Peltier element certainly counts as "active" and I know of no camera using one. Also, Sony explicitly states that the A7SIII is cooled passively. That being said, a Peltier can cool ...

Sorry, but this is speculation and does not make sense. There is no active cooling in any full frame Sony Alpha right now, so there can't be any power consumed for cooling. In the contrary, using ...

Also see https://phillipreeve.net/blog/minolta-mc-rokkor-11-7-55mm-review/ I've got the MD 50 mm f/1.7, but haven't used the 55 myself. There are different versions of both lenses (two for the 55, ...
