After much deliberation I recently bought a Sigma 18-125 OS. I was upgrading from my 18-55 IS and was debating between the 18-125 and a used 17-50 non VR. I ended up choosing the 18-125 because of its range and OS (which would hopefully give me similar low light capabilities to the 17-50 as long as my subject wasn't moving). If I had gone with the 17-50 I would still have nothing in the telephoto range and would probably have to buy a 55-250 to go with it, so I figured I was saving some money too. I currently have a 50mm 1.8 and I am planning to also get a 85mm 1.8 soon and a 30mm 1.4 when I can afford it. This way I have a set of primes they will do much better in low light than the 2.8 on the 17-50 and I also have a good travel zoom. Does this seem like a good plan to you guys? I can still return the 18-125, but I recently went to Spain and enjoyed shooting with it (although I did wish it was faster sometimes...). Am I being stupid keeping the slow and less sharp 18-125? What do you think of 30mm 1.4, 50mm 1.8, 85mm 1.8, and the Sigma 18-125 as a kit?

Do you own the 18-55 IS kit lens? If so, it and the 55-250mm IS make a very nice combination. A lens like the 18-125 (or 15-85) can be very convenient though I suspect you may still find the need for an even longer telephoto lens at some point and in some situations.

Another good reason for owning the 17-50mm f2.8 is the ability to control background blurring letting you seperate your subject from the background. Primes can do this even better but there's a lot to be said for having this ability in a sharp standard zoom. Not that I'm trying to say you made the right or wrong choice - everyone is different.

The Canon 85mm f1.8 is VERY nice. If you like the 50mm f1.8 I think you'll LOVE the 85mm.

Happy shooting!

On the 18-125mm, do you mean slow because of the f/3.8 or slow because of the AF speed? I find that it focuses just as fast as any lens I've used... but if it's the former, then you're probably right- you'll want something that performs better in low light.

Stay with the Sigma as a general walk around lens when light is abundant... then when indoor switch it out for the primes... nothing better than fast glass indoors... I never found 2.8 to be fast enough indoors... that is why the 30mm f/1.4 and the 85mm would be perfect....

I've always found f2.8 fast enough for indoors, I guess that's why I like the 17-50

What's your budget and what's your shooting style ? I'd say keep the 17-50 and get an 85mm 1.8. Then look into a 30mm prime. If you like wide get a Tokina 11-16 and for telephoto a 70-200mm L.
