Timothy, Billingshurst

Score 10.0/10
Good points:
Small light weight carry it all the time. Build is second to none as you'd expect from canon. Image quality is good on a 100-400mm L lens , but don't expect top quality at full 960mm hand held. Use a tripod/monopole and things improve.
Bad points:
None.
