It's not a DSLR.
Cy Cheze: Would an ordinary spectator be allowed to bring a G5 with the 140mm lens into an Olympic venue?Might it be possible to get reliable focus by simply setting it manually for the approximate distance of the competitors?Realistically, only a few people have close-up access where narrow DOF (or tricky focus) would make quick AF crucial.
I saw several DSLRs in the audience last night. Lenses longer than 30cm are not allowed.
vtinitus: Is there really a lumix 7mm-300mm lens? I couldn't find it anywhere...
It's F4-F5.6 in exposure terms, 8-11 only in DOF. Sounds like an advantage to me.
