>>3924570They're great anon.
I'm a bit biased about them, but I consider the OM-2 and later series as the best all around, practical cameras.
I've written many times about them, but the gist of it is
1. huge and bright viewfinders
2. great and accurate metering especially for low light and long exposures
3. great TTL off-the-film flash metering with the dedicated flash units (cheap). Basically you can use multiple flashes (connected with cables) and bounce etc. and it will give you great exposures without having to do anything manually.
4. very compact for an SLR
5. well designed all around and ergonomic, with little features here and there that will make you smile
6. all the above extends to the design of the lenses too: very compact for their performance/speed, and well made, while not overly expensive cause "dead mount" that doesn't adapt easily to dSLRs (though with mirrorless that can adapt anything, the gap has closed)
You can build a very decent system for a good price. The best value for money trifecta is 28mm f/2.8, 50mm f/1.8, 100mm f/2.8. The 24mm f/2.8 is very good too but slightly more expensive. The 35mm f/2.8 shift has tons of shift and a very clever mechanism, while not being reasonably priced (for a shift lens).
Also consider the OM-2SP (underrated), and the OM-4. They're not much more expensive (actually the OM-2SP is cheaper) and offer some extra features. (in a nut, a manual backup speed at 1/60 that works without batteries, a spot meter, and for the OM-4 a 1/2000 top speed).
If you have any questions ask away.
