I am looking for a lens to cover the mid range for my 30D. My current lenses are the EF 50mm F1.4, Tamron 17-50mm F2.8 and the EF 70-200L F4.
I am looking over the next couple of months to add the EF 10-22mm F3.5, the EF 100MM F2.8 Macro and eventually a EF 400mm f/2.8L IS USM.
I would like however something to span the range between the Tamron 17-50 and the 70-200. Any suggestions. I am pleased with my Tamron at this point so I don't forsee giving it up. However I could change my mind depending on the suggestions. My current spanning method is the tried and true "Feet" method. There are times however that changing postions is not practical. Would like to stay in the no more than $800 to solve this problem. (Less with good glass would be better).
