Originally posted by conradj Actually, i'm leaning towards no viewfinder. You know, a single focal length, manual focus point and shooter. As long as it has focus peaking and is fairly small, i could retire my P&S cam.
In which case, you're almost certainly looking at an APS-C body.
For APS-C, note that the field of view from your lenses will be cropped (since the sensor is cropped from size those lenses were designed for). As such, 50mm will feel more like a short-tele / portrait lens... 28 to 35mm is good for general use... for wide angle, you'll need to be looking at 24mm or wider lenses.
I mention this because most people that have accumulated a bunch of old lenses without specifically looking for wide angle models will typically have focal lengths from 28mm upwards. If that describes you, bear in mind that you won't have wide-angle capability unless you add a 24mm or wider lens, and the prices of those tend to be higher than the more common models from 28mm upwards.
