Sounds good, many thanks mate for sharing. 4.5 and 3.7 probably not much different. for the cost savings i think i can live with it.
Btw would Canon/ Nikon give out extra stuff during comex time? Not that i plan to go during to the IT Show, but current freebies can't fight with a Nikon. E.g. Hood, Tripod(Although quality maybe not impressive), Filters etc
