You probably have already realized this, but if you wish to make similar use of your existing full frame 35mm film camera lenses on the digital camera, you need to choose a camera with a sensor size that is the same size as the film cameras.
To illustrate, my Olympus OM film lenses work fine on my wife's Olympus OM 4/3 camera, but the 50mm lens performs like a 100mm lens, and I have difficulty achieving anything close to the wider angle lenses without buying either a shorter lens designed for M4/3, or acquiring something like a 15mm film lens - not practical or even particular good for the application.
