Looking at this also, what accesories and lenses would you like to see ?
I guess there's a short-list of lenses that are commonly recommended here and on other forums which offer good bang for buck and are likely to be popular. I'm thinking of things like:
Canon:
10-22
50 mm f/1.8
17-85 IS USM
70-300 IS USM
70-200 (f/4 or f/2.8, depending on depth of OCUKs desired range and how pricey you wish to go)
17-40 L
17-55 f/2.8
Possibly the 100mm macro?
Sigma:
10-20
17-70 DC Macro
18-50 f/2.8
70-300 APO DG
Possibly also the 50-500 and 70-200 f/2.8 HSM
I'm sure there are a few other favourites, but these cover both budget, mid-range and high end across the zoom range.
As for accessories, I'd also vouch for Optech straps, Sandisk cards, Rocket blowers and the 430EX Speedlight. I think it's hard to compete against the big auction site for filters etc. In terms of cameras, I think there's a place for both the 400D and the 30D (or whatever it gets replaced by, at some point). Bags would also be nice, but there's such a huge range and it's very much a personal choice thing I'm not sure how profitable it'd be to keep stocks.
Choices around dSLRs are so personal and use dependant it's difficult to determine what to stock and not stock to adequately cover demand........however, the suggestions in the thread do seem to give a reasonable startpoint.
