I just upgraded from a T3i to the 70D. I`m really enjoying the 70D a lot. I am thinking about getting the Sigma 18-35mm 1.8 to go along with it. I`m currently using the Tamron 17-50mm 2.8. Have any of you paired these two together and if so what are your thoughts?

If you have a Tamron 17-50 f/2.8 what are you hoping to gain?

I want better low light pictures.

That Sigma is the best EF-S lens on the market.

Don't hesitate.

1 1/3 stops!
I have the Tamron 17-50 nonVC and I bought a Sigma after renting one. It is THAT good. It is the difference between ISO 3200 and ISO 1250 ;)

I had that combo before I went FF and it is killer. The 18-35 lens is heavy, so be prepared for a little adjustment period. But it is definitely worth it.

It's great but sometimes it tends to hunt in autofocus. I'm not sure if its the lens or my 70d's center point as it nails focus on any other point when using f1.8-f2.8. But when using the center af point, it seems to go crazy sometimes. I use it as my main lens and have tweaked it using the sigma dock. Pictures are sharp and the low light capability is excellent.

The lens is on back-order at the moment but I`m on a waiting list. Do you think it would be wise to go ahead and get the docking station or just wait and see if there are any issues first?

Wait to see if you have issues. You can always use the built in MFA on the 70d to see if that even fixes any issues you may have. If not, then get the dock or send the body & lens to sigma to calibrate.

I own the Sigma 17-70, and it hasn't touched my 7D since I picked up the 18-35! I am hoping to make the leap to FF in the next month or so, and I may just have to hold on to the 7D just so I don't have to sell the 18-35!
