You can't really go wrong with any of both lenses, but I would buy the 17-55 if I wasn't planning on upgrading to full-frame anywhere soon.


It's a great lens, I personally think it's the best general lens on a crop-body. The IS and f2.8 combo is also really good, I don't use a tripod that often too []


And yes an additional 50mm prime is great. The 1.4 version is a step up, also take a look at the Sigma's [](Have to promote that lens guys[A]) Although personally 50mm was too long for me on a crop-body.


Good luck!
