...and I'm wondering if I should just wait to make a decision. Here's my current situation. I used a big chunk of my "startup" money (money to buy equipment at my university job) on a 70-200 2.8L IS, which should be here soon. I have a T1i, the 18-55 kit lens (which I find a bit soft, flimsy, and imprecise in low light), the 430EX II, and the EF 50/1.8.
Since just before x-mas, I've *had* the Tamron 28-75. I generally liked the IQ on that; but the build quality left a lot to be desired. It just felt "loose" and would wiggle a bit. Plus, I was missing the wide end a little and found myself shooting at the extremes of the lens -- 28mm and 70-75mm. So I sent it back to Amazon. As I mentioned above, I'm not really happy with the kit lens (aside for being a backup) and I'm looking for something at the wide (though not ultra-wide) end ... mostly for candids in close quarters (e.g., at the bar) and some general walk-about type stuff (architectural shots, street scenes, etc.). I know there are a million threads on this, but I still couldn't figure it out based on my circumstances; so here are my choices:
I know, I know. Just bear with me here....
I'm not really worried about the 40-50 range. If I want to shoot at 50, I'll put on my Nifty or I'll just move my body. A big part of me knows that I should probably choose the Tamron given that I was generally happy with the IQ its slightly bigger brother offered; but I'm worried about its build ... and I can't stop going back to the BEAUTIFUL pictures in the 17-40 images thread. On the other hand, I recognize that a lot of those pictures were shot on FF cameras; even those shot on crops, though, are just stunning. Plus, the accurate, quick, and quiet AF of the 17-40 would be mighty nice.
Given that I've been taking my flash with me just about everywhere, am I going to miss the open end of the Tammy if I were to go with the Canon? Am I going to find myself SOL in museums or at weddings where flash is less of an option? Let me try to break down what I'm attempting to weigh:
- wider aperture
- wider focal range (by 10mm)
- longer warranty
- only okay buld quality
- loud AF that can hunt
- better color and contrast
- fast, quiet, and accurate AF
- great build quality
- FF compatibility (many years down the road)
- only f/4
The ideal lens for me would probably be the 16-35 or 24-70; but both of those are out of my price range. Truthfully, the 17-40L is pushing it; but I can make it work. I guess what it comes down to is this: Do the AF and IQ strengths of the Canon outweigh the faster aperture of the Tamron?
Help me, POTN ... you're my only hope.
