How do these compare in terms of durability/feel? Some people find the Bessa's to feel cheap/plastically while others do not, but it seems that the R2/R3/R4 cameras have a better feel. So I'm wondering, is the T built better than the R? I've handled none of these cameras, so I'm not sure what to expect. I have a Canon P and it feels real nice, but the focusing is a bit difficult, so I'd like to accompany it with a Bessa. Also, how do the patches compare?
