Pros: Weight, size, sharpness

Cons: For what it costs no one

Opinion: I bought this lens almost for fun, to complement the various zooms that already included this focal length. I was positively impressed by the sharpness of the images and the speed of the autofocus, also considering the price range (especially in the used one) and use (amateur / advanced amateur, but not L series). In addition, the dimensions also make the R6 a light and inconspicuous car even for street riding in the city. Super recommended!

Pros: Dimensions

Cons: Nothing

Opinion: If I spend less than 300 euros for a 28mm/2.8 I don't expect the moon but this is a good lens and the only one (at the moment) that transforms an R6 or (even better) an RP into a compact but still FF. The focus is in line with the STM system and the sharpness is good even at full aperture and excellent when closing down a little. On the road with an RF 16mm/2.8 and RF 50mm/1.8 it's a treat.

Pros: Size, Speed, Brightness all

Cons: maybe the parasol is missing...

Opinion: I mounted the 28th on my brand new R6II and for a whole week of travel to London (without work commitments) I never took it off... I didn't really feel the need for anything else. Very fast, he does his job and he does it very well. The super small size makes it really good even for street music.

Pros: Excellent optical quality; lightness; extreme compactness; Control Ring

Cons: There is no weather sealing, but from this level it is normal.

Opinion: I've owned it for some time now and so I think I can express my opinion. I am really satisfied with this perspective from all points of view. You buy it first of all for its lightness and compactness: mounted on the Canon R, it fits in the pocket of your jacket. This being so inconspicuous makes it interesting in situations where you don't have to be very intrusive, such as in the street. The optical quality is very high in terms of resolution up to the corners, already at TA and constant up to f/8. Distortion and vignetting are present but it is known that this generation of lenses was created to be corrected via software which in this case corrects very well. See the review of Optical Limits. The presence of the programmable ring nut is also very interesting despite the compact size of the whole. The final grade, considering the sense of such a compact lens in the RF optics park, is a nice 10.

Pros: Tiny, fast and crisp

Cons: few, perhaps the lack of stabilization

Opinion: It is a more than honest lens in all its characteristics but its strength is undoubtedly the very small footprint. Little more than a cork.. I mainly took it as a "backup" lens to have in my bag in case the all-rounder zoom broke when I'm away for work, and luckily I never had to use it. So I loved it for light outputs on the RF (almost pocket-sized pair) and video on the R6, I would say excellent, it never disappoints. Maybe a bit expensive as much as I paid for it (more than 400 as soon as it came out).
