Re Sigma / Tamron Lenses.
Someone once told me one of these are assembled by being screwed together and the other glued together, is there any truth in this ? I would imagine the screwed together one to be stronger but haven't found anything to support this.
Also, currently waiting for Nikon's D7000 to come out before I decided on either that or the Canon 7D.
So would I be better getting a specific manufacturer lens or would Sigma / Tamron give as good results ? I've read a lot of reviews and it seems at times one is favored over the other only for the next month the reverse to happen. So I'm looking for peoples own experiences with these, any problems ? As opposed to starting a debate like which is better a Mac or a PC
I would rate myself as very keen amateur, it's unlikely I'd print anything greater than A3 size but I'd like the best I can afford ( about £500 quid on a lens I think ).
