So there you are with your new Canon T7i and some Christmas money… so what to do?
Buy the pancake of pancakes! The Canon 40mm f/2.8!
It’s a cheap, sharp, straightforward lens!
Canon’s 40mm f/2.8 lens comes in at a whole four and a half ounces and a massive ~ 1 inch thick.
It’s cute, it’s simple, it’s super easy to carry around with you.
Dust really doesn’t seem to be a problem.
And the weakest part of the build of this lens is the focus ring. It becomes extremely loose after extended use. But still usable.
A Bokeh Example
At f/2.8 you still have a relatively sharp lens with okay bokeh.
But the bokeh only gets worse from there… You’ll reach the end of usable artsy out of focus areas at f/3.5… It’s just not pretty.
I have years of experience with the lens and I can tell you that not once have I gone “that’s a pretty background” when looking at images from this lens.
So bokeh is genuinely something not to like with this lens. But for $180 I suppose that’s okay.
Anyways, you’re better off skipping everything past f/2.8 and just go straight to f/7.1. At f/7.1 and f/9 you’ll get nice sharp photos.
The price of the Canon 40mm f/2.8 really doesn’t change much. I bought mine five years ago for $179. You can now purchase the same lens for… $179.
Pricing is also pretty constant in the used market for this lens at about $130.
Ultimately this is an okay lens at an okay price. You could do worse than spend your Christmas money on this lens. It’s basic, straightforward, and very usable.
