Hey all, I've been saving pennies.. a lot of pennies.. since I picked up the 50D and I've been considering getting my first piece of L glass. I've purchased two lenses (one I used to use on my Rebel XTi) and since then have rented a few and after using even the 50mm f/1.4 and especially after the 70-200mm f/2.8L that I wouldn't spend any more money on in-between lenses and that I would either have the L-series for that range or make due without it until I can. This brings me to the 16-35mm f/2.8L. I really enjoy wide angle lenses and believe this is the right lens for me. I've read reviews on B&H, Amazon, DPReview.com (they only have data), but I would like some first hand experience from individuals on this forum if anyone has come across this lens. I don't see it mentioned often nor do I see it much in the sig-gear-lists so I thought I'd see if I'm missing something that should make me reconsider this choice. So if you're used this lens drop a line both good and bad and any other directions I should go instead so I don't waste my pennies. Thanks for reading.
