I presume the mating is not universal but unique to each camera. Will be mating to 20-60, 30 Wide, and 45 power. I need to start from no knowledge as to the best non-commercial cameras and their capability. Any help will be appreciated.
If you have the swaro modular stuff, as in, the STX or ATX for your 65, you can buy a DSLR of your liking, and get a swaro TLS APO of the correct mm and the adapter for whichever camera body you get.
I run a cheap canon T3i presently, on an STX with 95mm objective.
Here's a short clip of some video I shot of a prairie dog at about 125yds away.
