I probably cant justify it as just a nice little prime, even though it is, but it seems to me it would make a great pano lens, so long as your past the vignetting, parallax issues should be minimal too?
Should be good for pano purposes. Personally for me, I really like using alt. MF lenses for panos with their hard infinity stop (useful during night). Zeiss 50 1.7 and Takumar 50 1.4 are good candidates for even cheaper than the 40STM
I've done some stitching with it, its pretty good. (excellent for its price actually) Better/sharper than any of the Canon 50's I've tried, or the 45mm tse. But does not have the wow look of the 35L or 24L.
Only bad thing I can say about it, is it can be more tricky to manually nail the focus using live view, due to the tiny crappy focus ring. But it gets the job done.
That is gorgeous. I'm getting mine this week off Adorama soon. Will be my walk around lens on the street. Very discreet and light weight Will pair nicely with 5D2.
Here are a couple I did a few days ago, testing my lens after it got back from Canon. Mine was out of whack, and required three trips to Canon to get sorted out. Now it seems quite stellar.
