I made a video to show this problem, I had to use my phone and it's not great but it shows it
the steps to reproduce this problem
1. Set the EVF to standard (60Hz 9.4 million dots)
2. Set the camera to AF-C
3. Half press the shutter button to initiate AF and AE
4. As long as the shutter is half pressed the EVF image looks coarse to the eye. If you have a target such as an MTF chart this effect will show as moiré’ or jagged lines
I provided this info to Sony. we will see what they say. I encourage all owners of A1 to call Sony and share their finding, this will put more pressure on them to fix these issues.
Possibly, but so far not 100% convinced. My observations and questions:
- Is the camera exactly perpendicular to the target? You can see changes in framing, possibly angle before after pressing the shutter button.
- Is the camera on a tripod to avoid that?
- Can you repeat that with a single focus point located at the exact same point to avoid the focus to change position? If you are not perfectly perpendicular then depending on the specific location the focus point is located, different parts of the map get a bit in/out of focus which can lead to the moire. The green dancing squares seem to indicate this.
First, I don't need to convince you of anything. this test was to confirm what the OP had seen
- yes
- yes
- the camera is perfectly parallel the iphone is not perfectly parallel to the finder. The focus was locked in the test so there is no in and out of focus.
I am not going to test again. If you have an A1 go test for yourself and you will see the resolution drop easily. if you don't have an A1 why bother?
