Mount Compatibility
22 pos · 58 neu · 12 neg
“Now, let's mount the lens onto my APS-C camera, a Canon EOS R7 with its very demanding 32 megapixel sensor.” — Christopher Frost
Price & Value
50 pos · 16 neu · 27 neg

Distortion
6 pos · 5 neu · 8 neg
“Well, Canon is maybe the worst offender amongst modern lens makers when it comes to leaving things like distortion and vignette uncorrected.” — Dustin Abbott
Vignetting
16 pos · 5 neu · 10 neg
“And finally I'm sure you're asking about vignetting which is something photographers hate on their photos and it simply means that at the widest apertures of course the lenses tend to make corners darker.” — Jan Rybář
Chromatic Aberration
2 pos · 10 neu · 18 neg
“Now, one of the things you might find with a nonL lens from Canon is that you might get a lot more purple fringing and green fringing around the edges of images.” — Jared Polin
Coma

Bokeh
30 pos · 7 neu · 5 neg
“So, as you may well know, this lens got a lot of complaints about it bokeh at release.” — James Reader
Color Rendition
7 pos · 2 neu · 2 neg
Filter Thread
8 pos · 10 neu · 2 neg
“This 45 mm has a 67 mm filter thread and a fixed barrel design, which means it doesn't uh extend outside of the lens just like the 28 mm f2.8, date, which can be a little annoying.” — GlennVanderbeke
Dimensions
19 pos · 10 neu · 3 neg
“The front is a 67 mm diameter which is impressively small considering this is an F 1.2 lens.” — ProAV
