Pros: Compact - AF fast - blurry

Cons: Tropicalization

Opinion: If this project has not been updated or changed there are 2 reasons: the first is the fact that the lens does more than excellently its duty as it is, the second is that although it is not perfect, it represents a bright fixed at ridiculous costs (for the focal FF) usable in all excluding architecture. It may not be monstrous at the corners, but it certainly has a pleasant yield and blurry one. if I had to give a definition I'd say it's a Canon. And by that I mean that it's a lens whose photos stand out, have character and personality, are not sharp at the edges and do not even have any distortion, but the outcome is pleasant. It generates poetry and atmosphere as long as you devote time to it. Beautiful focal on aps-c

Pros: Brightness, accuracy and AF speed, sharpness already from f2.8, blurred, minimum focus distance, general yield, flare resistance, little distortion, cost

Cons: Optics a little forgotten and very underestimated, it could have become perfect if it had been F2, good but discreet flare resistance compared to other optics such as the 17-40

Opinion: Recently purchased and impressed me immediately... a lens that in my opinion can satisfy many genres, from landscapes to the street, up to portraits and ceremonial works... its speed and precision, even on machine bodies with not fast and recent focus make it suitable for "fast" and silent situations.... a blurry then gorgeous for such a wide focal, sharp already slightly at 2.8, closed at 3.2 or 3.5 already makes much more... to very closed diaphragms it retains well its resistance to flare, which really amazed me, overall then has a pasty and delicate yield, it is not an L series of course but by its standards you can work very well professionally, for less than 350 euros I highly recommend it to everyone !

Pros: Construction, sharpness from f4, to 2.8 good, very low distortion, soft color yield, vintage colors

Cons: Vignette, backlight in critical situations

Opinion: I say that I use it on 6D, I honestly found it very good, on the web the vast majority talk about it very badly, I do not understand what parameters of observation are made. Natural colors not contrasted, shadows not closed, low distortion, excellent sharpness from f4, by necessity you can safely use even at 2.8, in short for me it is a very good lens so I completely disassociate myself from the negative comments of others. The construction, although not an L-series, is dignified and robust. On the other hand, the vignette is elevated to the most open diaphragms but it is corrected in a quiet click, and the backlight but only in really critical situations, sun in the frame. I recommend it, low price especially in the used and excellent quality in general.

Pros: construction, chromatic rendering, distortion

Cons: slight loss of sharpness and vignetting at the extreme corners only with full frame

Opinion: Great focal length of 20mm, it allows a little bit of detail to frame virtually everything without distortion, this particular that I use for a long time returns a chromatic tonality in the wonderful interior, good focus with center point on both 5D old and 6D, excellent sharpness in the middle and discreet on the edges, it only smacks a slight vignetting and sharpening but only in the extreme corners with full frame.

Pros: 20 mm! Superb corner on both formats! Auto focus Usm fast and interior, color rendering, controlled distortion, light, resistance to flare, sharpness and brightness!

Cons: I have not noticed ...

Opinion: Amazing corner of FF, a real wide angle with controlled distortion that becomes a 35mm equivalent on APS-c. Excellent auto focus, construction and optical quality without compromise, all metal, with internal af, lightweight and portable, in my opinion very clear as well as light, excellent color rendering! rnL'unico against the yield seems to be poor at the edges, but on 5D old I frankly have not noticed, let alone with the crop of aps-c ... perhaps it is less suitable for sensors more recent and demanding being a project a bit dated. However, a good goal, in its own unique way to the strong identity that has both formats, if you are familiar with fixed lenses inevitable and better the old 24 in all, with quality and yield more than good, considering the price!
