A camera with one lens is fairly large.
A camera with two or three lenses makes for a portable kit. In my case, I've settled on a C330 plus 65mm and 135mm lenses. In the past I've had as many as four lenses, and used to use them for weddings.
I would suggest a C330 or C220 instead though - the C33 is quite old.
If you intend to stay with a single, standard lens the Yashica is nicely compact.
