well i want to go to autofocus and for professional standards, high frame rate along with durability. I would like to get into freelance when i get to college so eventually i will get a DSLR until then.
I probably have 15 cameras at the moment including 3 X 370's, a X 570, a X 700. I'm still a Pentax guy as I'd started with screw munt and Pentax was most "backward compatible" ....well...they still are, the Current DSLRs are happy to use ANY ols Pentax bayonet mount and with the same adapters-screw mt. Pentax put the "anti-shake in the BODY..so it works even on an old K mount.
My "Main" body now is a Pentax ZX 5. It has a old school shutter speed dial. It has SPOT meter,,,important to me, it has a built in diopter adjust so I can shoot glasses off. It has TTL flash...I hate "calculating" a flash shot. I have a slave and a 283 Vivitar-and that works nifty with the pop up.
Has winder,has Multi-exposure (also a feature I need) has AR/SP/Prog, though mostly I do manual and aperture priority, has a add on pack so 4 rechargable AA's power it, has winder.
ZX 5's have a VERY chronic issue. Most of them, the pop up flash loses the ability to stay up on it's own. It's easy to hold up with a finger. The ZX-5N is a bit better..as I recall the main + os a DOF preview button. An "n" however will tend to cost more (
ebay).
The SF-1 is a good AF Pentax. It dies lack the spot meter. Great viewfinder,includes ediopter adjust. The PZ-1 is top of the PZ series-sweet if you can get it but the ZX-5 has most of the same good stuff + the "manual friendly " aspect.
While my ZX-5 is AF and I HAVE AF Pentax glass..I find I PREFER some of my non AF SP Tamron zooms, Pentax K Primes and my M42 macro bellows rig. I have a rare adapter that lets me put a M42 on the ZX 5 and have the auto stop down linkage...which makes the auto bellows way more handy.
What's unique is If I get a Pentax DSLR..all that still works. I have glass that can work on my old Mamiya, my K mount Chinon, My AF/k ZX5 Pentax AND the Pentax DSLR I might get someday.
Note....SOME nikons have good "backward compatibility" To some extent you can put a '78 vintage Nikkor on the higher end AF Nikons like N80,N90,N100. SOME Nikon digitals (again-probably the high end) can use most Nikon lenses.
With Canon, the EF type (ROS) lenses tend to work with Canon DSLRS while Maxxum AF lenses should work with Minolta/Sony dslrs
