Great lens (wedding photographer's perspective)
9
Hi there!
Here's my experience of the RF 35mm 1.8 STM Macro compared to the EF 35mm 2.0 USM. I've used both for a few weeks on an Canon R6 body and am keeping the RF lens. This is not an super in-depth review, but rather my real-life experience as a professional wedding photographer (7 years and counting) with a style that is all about capturing spontaneous moments.
Image quality
Absolutely fine and visible better than the EF version, especially away from the centre. I'm not a huge pixel-peeper, but feel the RF 35mm 1.8 is a bit sharper in the corners and when used wide open. (Just for fun I did a brick-wall comparison to confirm). I have no hesitations to use it wide open when shooting a wedding, even when I compose a subject in the corner of the frame.
Focus speed
Was a little worried about this one, but after using it for a while now it's been completely fine for me and I feel it's plenty fast. Yes, the USM motor of of the EF 35mm 2.0 might be a tad faster in theory (and probably is), but in real-life scenario I found it hard to find a noticable difference at "normal" distances (i.e. when photographing people). Only when switching focus from super-close to far away do you notice a little speed-difference between the STM & USM motors, but I can't think of a scenario where this would be a problem for me. Even my little kid running around at the playground didn't pose any problems and focus & tracking were spot-on.
STM noise
This was mentioned in other reviews and I was hoping this wouldn't be that bad...and it isn't. The STM motor is not as silent as the USM version, and when you pay attention to the focus motor in a silent room it's slightly audible. But again, in reality no problem whatsoever, and I doubt anyone besides the one holding the camera would hear the lens focussing (and that's in a silent room!)
Other thoughts
I wish a hood was included (it's not) and had weather sealing, but then again I'm not one to stand out in the rain to take pictures and have only once encountered a scenario where I was happy to have weather sealed lenses during 7 years of wedding photography, so it's more a thing in my head than a real practical problem. Lastly, it just looks nicer on and R6 body than an adapted EF lens
