Due to the high resolution, your A7RIV is quite a lot more demanding than your other cameras. There are some aspects that might cause unsharp photos that your other cameras are less picky about. You should adjust your habits to get the most out of the A7RIV's high-res sensor:
- Subject motion blur (use faster shutter speed)
- Camera motion blur (use faster shutter speed or tripod)
- Lens unsharpness (use sharper lens)
- Diffraction (don't close down the ape
I bought a A7RIV a few months ago and I've gone out several times to go shoot. The first photo shoot (portraits) I had with it, the focus looked spot on in camera but wasn't in focus once I got it on the computer. I thought it might have been the lens I was renting so went out to shoot some landscape shots with one of my trusted lenses. The focus looked great in camera but off when I put it on the computer. I immediately took it back and exchanged the camera. I shot again with the newly exchange
Hi Gang, is there a guide somewhere to which of the older minolta lenses and sgma/tamron

of cheap long lenses on ebay, some are minolta some sigma etc, question is which will work ok with my A7ii dslr
I have never done any astrophotography. It is my understanding that with the a7Riiiii raw uncompressed, the only change that happens by selecting a picture profile are the gamma settings.
Therefore, which picture profile, if any, is best for astrophotography? Thanks very much for your help.
