Canon 40mm f/2.8 STM Lens

I think I first heard about the Canon EF 40mm f/2.8 STM lens from Marco Arment. Wherever I heard about it, I’m glad I did. Mine arrived in the post this morning, so I slipped this lightweight, ultra-small prime onto my 60D and headed out to take a few test shots.

So far, I’d say it’s a great lens. It adds virtually no weight or bulk to the camera, and it’s even more subtle than my usual small standby, the 50mm f/1.8. Focusing is smooth and quiet with the new stepper motor tech — the near-silent focus is meant to be good for shooting video.

The difference between 50mm and 40mm doesn’t sound a lot, but on a crop-sensor camera, it’s significant. I think I’m going to find myself less frustrated with the 40mm than the 50mm, where often I feel like I can’t step back quite far enough for a subject.

The manual focus feels a bit unusual — it’s a “fly-by-wire” system where turning the focus ring in manual mode actually drives the stepper motors. I’ll get used to it, I’m sure.

About the only thing I don’t like compared to the “nifty fifty” is a necessary result of the “pancake” style — the lens glass is very exposed. I’m used to being fairly casual about carrying my camera (usually on a Black Rapid R Strap.) This isn’t a problem with my “nifty fifty” and its recessed lens, or with my other go-to lens, the 17-55mm f/2.8 IS, as that always has a big lens hood on the front. The little 40mm pancake risks having its glass bumped headlong into things if I’m not a bit more careful, though.

Still, the light weight of the 40mm means that the shoulder sling may be overkill. And I notice Black Rapid are doing a Wrist Strap that will clip straight to my existing R-Strap fastener. That, though, will have to wait for my next new toy shopping spree…

    Lovely pics, and interesting review. I’m intrigued by this lens and trying to decide whether to save up for it…but I probably have no excuse, because I already have access to my husband’s extensive collection of Canon lenses.

      There’s *always* room for one more lens! :D
