Canon EF 40mm f2.8 STM Initial Review Collection

It’s been a while since we’ve seen thin, compact, pancake lenses on DSLRs, only Pentax had compact primes made for the modern era it seems. While the Micro 4/3 format cameras have been getting a good number of pancake lenses ever since they were launched but Canon and Nikon have been slow to offer one.

Canon finally came up with a 40mm f/2.8 STM pancake prime recently and we haven’t been that excited with a ‘normal’ prime for quite a while since that range has always been a stranglehold for the cheap EF 50mm f/1.8 II for so long.

Not that the new EF 40mm f/2.8 STM is as cheap, but not that insane either at $199 retail (check current price and availability).

The EF 40mm f/2.8 sure has the specs and pricing to make this a very sought-after purchase after the kit lens, even the MTF figures aren’t too shabby.

Can’t start any video feature with Kai and his gang over at DigitalRev

Here’s an unboxing video from “CiscoRodarte”

And finally, an interesting video about the STM focus-by-wire motor (and see how it looks like with a 1D camera)

Reviews and Opinions

Here are three good write-ups about the lens. So far, things are favorable and for the price that Canon’s selling it for, it seems to be a very popular lens for EOS camera owners, not just for the price and image, but as thekonly true portable lens in the EF line-up.

Nifty Fifty Replacement?

I’m personally sold with this lens and 99% sure I’m getting one to replace my 6 year-old nifty fifty that’s wrapped around gaffer tape and all. At $199, it’s not expensive, and finally, I can carry a DSLR again without having a bulky lens protruding and hitting every corner it can find.
