I got a 6d, and I want a lens that will replace my sigma 10-20 with the 550d, but I never really needed the 20mm end of the 10-20.
I'd usually use the 10-20 for architecture and landscape.
I was planning on buying the 17-40, but I may just get a prime lens to save money.
Or would I really enjoy the 17-40?
I'd love suggestions on prime lenses or reasons why 17-40 is the better option. Thanks.

I currently own a Rokinon 14mm with my 6D. I tried 2 17-40 and every time I was a bit disappointed by the result, with very soft corners.
In the other hand the Rokinon is not that bad on the corners and being a bit wider I usually crop a bit where the distortion might remain too heavy after lens correction. It's also very sharp. Of course it doesn't have autofocus, but for landscape I usually use infinite focus and it goes well. The only real drawback is the lack of filter thread.

after googling, samyang seems to have announced a filter holder for the 14mm lens.

it would be nice if they released an update with built in filter thread.

I have the 17-40 because of price and zoom range. I can use it as a walk around lens pretty easily with that range and obviously for an ultra wide. I do agree the corners are a bit soft even stopped down to f/8, but it doesn't bug me as much as it might others.

This is the same way I think of the 17-40. I just upgraded to 6D & 17-40 from 60D & 10-22. I happy with the move.

I get what you're saying.
When I had the 10-20, I was using it strictly as a wide angle lens, so it would make sense to get a prime wide angle lens like the 14mm.
But the 17-40mm is more than a wide angle lens. It can be a walkaround lens. And I love walkaround lenses. It makes things so much easier.
I might have to give some more thought before I decide.

I have lots of experience with the 17-40 and have used it on two previous crop cameras (Rebel xt and 40d) as well as two full frames (5d and 5d iii). Many of it's relatively minor shortcomings can be addressed in post processing. I recently moved to the 16-35 F/4 IS which does produce better images and has image stabilization, but the 17-40 is smaller and lighter and a good used version can likely be found for under $500. I'm handing my 17-40 off to my stepson (who has also inherited my 5d and a couple of other lenses) rather than selling it. I'd highly recommend a good used one as prices will be low because of the introduction of the 16-35.

I got my 17-40 refurbished, directly from Canon, with a one-year warranty, for $546 ( 15% off sale). The 16-35 IS looks better, I'm sure. It is not worth the $1,000 differential, to me anyway. I like the 17-40.

Sounds like 17-40 is the choice to go with. Thanks for sharing your experiences with it.

So are you going to try using a 1.4x with your Sigma? It would be worth the attempt to mirror what others have found, and you can still sell it afterwards, and have a 1.4x sitting around.

I found out about the trick two days after I already sold the lens. I want to break something. I really wanted the TC for more zoom too. Idk if at this point I should buy back another sigma to try it. Probably not.

If you sold it, probably not worth it then, a 17-40 on the used market is within range of the Sigma 10-20 with a TC anyways. However for those that have an APS-C Sigma 10-20 sitting around, the TC is a great option. I just leave my 1.4x on my Tokina 11-16 full-time now.

Not physically possible. It would need a rear gel slot instead.
