Nice pictures Brian, Peg, and BillT. I especially like the Colt.
No camera stores locally or nearby anymore. Had one here for decades, but it closed before the net took off.
I would suggest getting a couple of smaller memory cards rather than one large 128GB. All the eggs in the same basket thing.
I just bought a Pentax DSLR with crop sized sensor and haven't even used it yet or finished reading the owners manual. I was torn between that and an Olympus micro 4/3 camera. In the early 80's I bought an Olympus OM-1 SLR and three prime Zuiko lenses, and later a Zuiko telephoto zoom lens, used.
Had to do a lot of brushing up on the digital stuff, and have lots more to go. What I liked about both the Pentax and Olympus cameras I was looking at was that both had Image Stabilization (IS) built into the camera body instead of the lenses. Additionally both had some weather resistance built in and weather resistant lenses are available. Both had an operating range down to 14° F whereas many digital cameras are only rated down to 32° F. Weather resistance (WR) and colder operating temperatures may not be a factor for you in AZ, but dust might be. In Michigan the WR and lower operating temperature makes sense to me.
On of the reasons I wet with the Pentax over Olympus is that the Pentax is a SLR with an optical throug the lens viewfinder as well as a screen. Some cameras do not.
Additionally virtually all older Pentax K-mount legacy lenses will work on the DSLR Pentax cameras. They won't work in a fully automatic mode, but will work in manual mode. I think the only way the legacy OM Zuiko lenses will work on the current Oly camera are in manual mode with an adapter that Olympus no longer makes, but third party and aftermarket adapters are available for OM series Zuiko lenses to Micro 4/3 and OM to Pentax K-mount.
I may still get an Olympus micro 4/3 camera also.
Brian, what are your thoughts on the different sensor sizes, FF, crop, 4/3, etc. and using legacy lenses with adapters?
