Tiny, smooth ring; fits and works great with my Panasonic 25mm f/1.7 lens!

I bought this lens to replace my old EF 85 f/1.8 lens. I was hesitant because of some bad reviews. But it turned out to be a great upgrade. Image quality is top notch – very sharp, good contrast and great colors. I use it on my EOS R6. Images from this combo are very clean (no haze that I often experienced from the old 85 f/1.8).f/2.0 vs f/1.8 on the old lens – this really didn’t matter much to me. The performance of the old lens wide open wasn’t great. I used f/2.2 or above for most of my shooting with it. This new RF lens however produce excellent results wide open at f/2.0. The bokeh it produces is very good too.And of course, this new RF lens has IS, close focusing distance and 1:2 macro. All useful features.Before buying this, I was concerned about 2 issues – slow and noisy autofocus and geometric distortion. Neither turned out to be issues for me. Autofocus is noisy but it is fast for normal shooting (0.5m to infinity). Manual/focusing for Macro (0.35m – 0.5m) is difficult, but Macro in general is difficult if you want to do it right. Geometric distortion (very minor pincushion distortion) is harmless, especially after lens correction.I am not much into videos, so no experience there.I am a hobbyist with 25+ years of experience using SLR, DSLR and now mirrorless. I very much appreciate the smaller RF lenses Canon is producing (I use RF 85 f/2.0, RF 35 f/1.8 and RF 16 f/2.8) to go along with compact bodies such as R6. Photography is fun again!

This is a very fun lens. Huge F stop makes it very versatile and a low price

I enjoy this Canon EF 50mm f/1.8 STM Lens for portraits on a Crop, APS-C x1.6, Sensor. It's equivlent to a 80mm f/2.9 on a Canon Crop, APS-C x1.6, Sensor.

For the price and quality, it is an amazing action camera. 4K, touch, responsive and a tons of adapters and tools. For 99% of people it is a better option than expensive action cameras.

Great little lens for the price. Has a hard time in the dark, but what lens doesn't? I really just need to bite the bullet and get the f/1.4

This is actually the first prime lens I have ever owned. My current kit includes a 5DS, 70-300L, and 16-35L. This lens is the cheapest and sharpest lens I own. I do landscape photography, and prefer tack-sharp images. I bought this lens to make high-resolution panoramas from a tripod.PROS- light- inexpensive- extremely sharp when stopped down to f/5.6 or f/8CONS- cheap build (compared to other mid range Canon lenses I own)- I got a piece of sand in the focus ring. Now it feels gritty. This hasn't happened on any of my other lenses, even the ones I took on the sand dunes.- The front lens cap is awkward. most lens caps extend to the outer barrel of the lens. This one doesn't.- Odd filter size- Near useless (for me) image quality at anything less than f/4. I consider this an f/4 lens.I'm happy with this lens for what it costs. I have no complaints with the image quality when stopped down- it is excellent. Wide open, I think "artistic" is the nicest way I can describe it. From a build quality and weather/dust sealing perspective, the price shows. I'm going to pick up the 40mm STM next to compare.

About a year ago I bought the EF 70-300mm f/4-5.6 IS USM lens. At the time, it appealed much more to me than its (more than three times the price) "big brother" - the lens did well for me but left me wanting MORE! I just got this lens, EF 70-200mm f/2.8L IS USM. It is worth every penny - those of you who have used an IS lens before will know what to expect in that regard, however if you have never owned a lens with canon's "L" glass, you are in for a treat! The color and image quality are far above the cheaper canon line. And the fixed f/2.8 is a fantastic advantage to have. I do mostly indoor concert photography and this lens has been a dream come true. (i know that sounds lame... check one out and you will see what I mean.!) If the fixed f stop isn't that big of a deal to you, im sure the f/4 is probably a good lens as well....however I can definitely say that this was a smart buy!
