"Canon EOS 40/2.8 STM (Sep 2015, 9/10) – One of the most underrated lenses in the Canon lineup. Barely larger than a body cap, and capable of great results by f4 even on the 5DSR. Has a lovely rendering style and plenty of pop. Not much at all to complain about at this size and price."

"I landed up buying a 24-70/4 IS L, 40/2.8 STM and 70-300L, and carrying these in addition to the manual focus lenses and a Nikon body for backup.
The 40 STM was the surprise of the bunch, and very enjoyable to shoot with because of size and image quality. It made a great aerial lens, actually – the right focal length for a natural perspective, not so long that you run into shutter speed problems, and not something that would be so physically large as to be affected by wind buffeting. It’s also a steal at $149."
