To use the opportunity older lenses via an adapter has particularly appealed to me. Example, there is really good Minolta MD / MC lenses for little money needed to buy. And these glasses are really fun. You have to be created manually focus but that's what makes me beside the good image quality from the thrill of photographing. My Minolta lens Park has cost just 200. A bargain. For the 7d there for the money no usable glass ... There are adapters for many other Obkektivsysteme as Canon, Nikon, Zeiss, and several more.
The kit lens of NEX-5N is useful and quite usable as "Always top". In my small camera bag I have the kit lens always there and next door is a 50mm Minolta fixed focal length.
The NEX-5N has grown me in the few days his heart. She's just always. The 7d will now be sold.
