I got the 17-55 to compare with my 15-85 and decide which to keep. The OS on 15-85 is almost dead silent. This is the first thing that I noticed, the OS is silent and it even makes a noise after I take the picture...is it normal?
The other thing is that I have bought a sigma 30mm f/1.4 yesterday. How do I make sure it's right for focusing and there is no problem? Would you keep it even if I keep the 17-55 ? or would you rather use the 15-85 + 30mm sigma?
if I decide to keep the 17-55, would it be a good idea to buy a 55-250 f/4-5.6 used in the time of saving for a 70-200L f/4
I also got a 50mm f/1.8 as a gift but due to price, I'll keep it no matter what. I also have a canon speedlite 430ex!
