IMO, don't need to go all fancy and expensive.
The Pentax K1000 was the poor students learning model from 1976-1997.
Very spartan, no creature comforts, but the needed controls to learn a camera was there.
I can shoot one, of course and do it for the engagement that I like, but often I am lazy too and opt to use some other camera with AF and metering, spot meter, auto film winder.
So you need to think what you baseline is.
and you budget.
Think about format and camera type.
35mm film, 645, 6x6, 67?
If you want to get maximum quality for film, go 6x6 or 67 (but you really need to do more research).
If you don't need the highest quality, 135 format is the easiest entry to film.
Cost is commensurate with film size.
Do ask and read around in the film section on CS (lots of knowledgeable ppl there)
RF/SLR, the eternal struggle....
Depends on individual.
Try both out in a shop or attend a film user meetup and the folks are usually more than happy to let you try.
I can't appreciate the RF method of use/focus, some guys are the other way round.
No right no wrong, just what we can get used to and preference.
I suggest a reputable online seller on ebay or a reputable forum user on CS (CS usually got good deals and you get to try the camera)
Film costs varies too much to mention here (BnW? Slide? Exotic film? all cost different).
Check out this link :
Think it over if film is the way you really want it.
Not because its different and cool.
No chimping (or rather each shot cost $); Limited post processing (hard to do and sort of blending; translation into digital?, etc.
I say this not because I dislike film but you better think over what you are getting into.
Need to be clear why you want to do it.
I suggest starting simple.
AF SLR with metering.
Need to have the typical modes of course (Shutter/Aperuture piority, M ) (others are bouns)
Center weighted metering will do fine (if there is spot metering, its great (consider it a bonus)
Plenty of such mid level or even higher end SLRs at under $200, look around.
It does not need to be a fancy highest end model if the price is too much.
Don't be over excited and jump in without proper search at prices and what the camera has.
