It was time to say goodbye to my kit lens (18-55 f/4.5-5.6). It's not like I was particularly attached to it, I knew I would eventually upgrade. And to be honest, I've rarely been using it. Since I got my 50mm f/1.8 last year I've been spoiled with a fast lens, and its really hard to go back to a maximum aperture of 4.5. So I was on a mission to get an everyday lens (that actually zooms) with a low f-stop.
In a perfect world I would have gotten the Canon 24-70mm f/2.8 but there was no way I was going to drop more money on a lens than my MacBook Pro. I thought about getting the Sigma 24-70mm f/2.8 which is a "bargain" compared to the Canon. I nearly made the purchase, but ironically enough I was watching Suze Orman at the time and it would have given me a guilty conscience.
So after reading lots of favorable reviews I went for the Tamron 17-50mm f/2.8 (thanks to my friend Dean for the suggestion). I bought it used and actually sold my kit lens on amazon for a pretty good price so overall, I didn't spend too much. I've yet to receive it so will post about it once I try it out.
UPDATE: love the lens, the 2.8 makes me happy. The two big cons in my opinion are that it's really heavy (significantly heavier than my kit lens despite the similar focal range) and the auto focus is so, so loud! Here is the first test shot I took with it (please no judgment on the ll bean slippers):
