We were lucky enough to get nice seats to the New Jersey Devils vs Anaheim Ducks. We brought the NEX-5 with a Minolta MD/SR to NEX/E-mount lens adapter the Minolta 45mm f/2 MD Rokkor-X. The combination easily fits into a jacket pocket.
The 45mm f/2 on the NEX gives an equivalent FOV of 67.5mm, which allowed us to shoot the width of the ice from our seats. Here are a few shots from the night. Most of these are cropped which shows the lens' and NEX sensor capability.
