Price not being an issue at this time (although I prefer less than $1,000), if you were to get a fixed focal length such as 50mm, 70mm, or 105mm, which one would you get? Same with standard zoom, such as 28-70mm or some other zoom, which would you get? I'm in the market to get two new lens provided the price is right and want to get faster lens. Also, who would you buy them from? I usually get my darkroom stuff from adorama but have not brought anything over $20 from them so I'm not sure how they are for the big ticket stuff. Would ebay be worthwhile? Can you recommend a seller that is legit on there? Thanks!
