Canon RF 10-20mm f/4L IS STM Review

[David - Sydney]

It really is an excellent lens, and while I initially held off on buying it, it's as good as my EF 11-24/4L in a far more portable package.

Do you miss the ability to use filters in the r mount adapter?

Not really. I now have the Kolari magnetic ND filters that drop into the body, and those work quite well.

My favourite ever lens. Same size as my other 2 f4L lenses, but a lot lighter, and just superb.

No complaints here, I like mine for its IQ and portability.
Do not love the hood design...
My biggest gripe with it it's not a fault of the lens per se: as a photographer, I find that it's difficult for me to use it successfully at 10mm. Not a matter of quality, just a matter of finding a composition that works at 10mm. I find myself using it much more at 20mm.

It seems that composition does become far more difficult at uwa.
