I’m planning to upgrade from a Nikon D2Hs (APS-C) to a Pentax K1 (full frame) (original, used) in about 2 weeks. My first (film) SLR was K mount and I still have a couple kit lenses for it.
For newer AF lenses, I think I’ll start with a 24-70mm f/2.8 and a 100mm macro. One of my owned K lenses is a Vivitar 70-210mm f/3.5-5.6 manual focus. I think I’ll start with that for tele as these two lenses and the body consume most of my $2,500 USD budget. I’ll also want maybe 4 SD cards (the body takes two, so a working pair and a backup pair), a spare battery and a travel case.
All of the softwares should support a camera from 2016 right? If I want to play with pixel shift, will that limit my software choice?
