The Rollei is so small that it's difficult to find in my pocket, and it's neither easy nor ergonomic in use. My Retina is quite solid and leigtweight but it no way gives the pleasure to hold as my IIIg does and then it's not easy in use. I'm privileged to afford the Leica IIIg it is such a perfect tool to work with. I am looking for an Elmar 2.8 to replace my Elmar 3.5.
good luck with you photography, MSBARNES.
