Pros: Small, light, quite affordable, decent bokeh quality for an ultra wide lens, good reproduction ratio, nice and sharp in the middle and most of the frame, works well against bright light and Sun

Cons: Soft edges, ridiculously small filter size, lens hood sold separately

Opinion: Well, for the price, this lens is a must-have. And it's rather unique, RF system only. I really enjoyed using it for close-ups, walkaround, landscapes, food, pets, cars, even portraits. It seems to be wider than 16mm when shot in RAW without lens corrections ON and the edge details look better when not stretched out by the lens geometry correction. Therefore it is better to keep the corrections OFF in many situations. Highly recommended!

Pros: Lightweight, compact and discreetly sharp in the center

Cons: Soft edges, lens hood

Opinion: Just bought for a trip I'll do in Portugal, put on Canon Rp it behaves quite well, it distorts a bit at the edges despite the correction in the camera. However on Rp it seems to have a compact in your hands, very fun to use, for the lens hood I tried that of the 50mm stm practically identical mount but you can see it in the corners.

Pros: Price, weight, size, image quality

Cons: Lens hood to be purchased separately

Opinion: Taken without too many pretensions, it actually turned out to be an excellent purchase. Although it is not the focal length I use the most, the low price (paid 230 euros used) has made it the ideal candidate to enter the RF world without breaking the bank too much. On the field test, as mentioned, here is the pleasant surprise: paired with R6 it is a combo of great quality and at the same time very agile and compact to carry around. Even in areas that are not exactly of choice for a 16mm such as sports and live music, it is very useful for panoramas, overall views but also "creative" photos. If before I was undecided, having to redo the fixed lens park, whether to opt for these non-L RF or take the old EF L series to use with adapter, this "taste" of 16mm convinced me to take (little by little) its 28mm, 35mm, 50mm and 85mm brothers as well. The only flaw I found is the lack of the lens hood, but you can fix it by buying a third-party one. In conclusion: absolutely recommended.

Pros: Lightweight and cheap, fast af.

Cons: Very pronounced distortion, very low image quality at the edges

Opinion: Bought to experiment with the focal length, I can compare it to the first ef 16 35 2.8 and I can say that qualitatively it is very far from it. In post production the distortion is well fixed but perhaps further cropping is needed to obtain a realistic image. The sharpness in the center of the image is good but pushing towards the edges is gradually pulped. Goal sold.

Pros: Lightweight, good sharpness in the center from 2.8, nice colors, well made, cheap for the focal length and quiet.

Cons: Lens hood to be purchased separately.

Opinion: Quite skeptical at the time of purchase, mounted on R6, it has the same dimensions as the RF 50mm f/1.8 stm, so it creates a particularly compact whole. After taking a few test shots already on the screen of the car they didn't look bad at all, then downloaded the shots on the PC, on the monitor my skepticism was dispelled. For what it offers and for the price paid, the results are more than noteworthy. Some may say that it is the result of the on-camera correction of distortions and aberrations, but given the results and how they are achieved I have nothing to object, also because I hardly shoot in raw with ML. Purchased for light outings, it does not make me regret having left the ef/rf adapter and the Canon EF 16-35 F/4 L IS at home, certainly more performing and versatile but much heavier and bulkier. I vote a nice full 9 deserves it all.
