All my gear is listed on my signature right now. I plan on getting a 430exII very soon. I really enjoy my 50mm 1.8 a lot more than my 15-85 because of the DOF. However, I find the 50mm to be a bit long IMO on my 1.6 crop. I am now considering the Sigma 30mm 1.4. If I do get the Sigma, should I keep my 15-85 still? I have a feeling that I will barely use the 15-85 once I get a 30mm. I really enjoy how the primes are so fast and can produce nice bokeh. I'll be heading to college in the fall and would prefer not having gear I might not use. What you guys think?
