I own a Canon SL1 and I've been a big fan of all the STM lenses, and ordered this new 50mm immediately. Long story short, I would get this lens without hesitation if you do not already own a 50mm but if you do own the previous generation of this lens, you may not be all that impressed because the picture quality that 50mm f/1.8 II provided was already great.This lens is excellent in value for just above $100 and the new STM technology definitely makes focus noise quieter, but not as silent as 18-55mm, 55-250mm lenses. Pictures come out sharp and the new version has metal mount that makes the entire lens feel much more premium with a little more weight than the previous version. The 5-blade improved to 7-blades inside the lens and has a more pleasant coating on the lens which is supposed to make light flares nicer. I think it's a little odd that the filter size went from 52mm to 49mm, but no biggie. So it's built well and focuses faster and better, but it'll still have a bit of downside that all STM lenses have: you can't adjust the focus without having the camera on because of "focus-by-wire", but you're able to override the auto focus by pressing down on shutter a step and focusing on your own. Although I think this lens can get away without having a hood, you can now hook one up same way as most other Canon lenses on the front groove. Oh, it also has a closer focusing distance too now so you can get closer to the objects.To sum it all up, this lens is fun to use and the wide aperture is nice and handy. This new iteration enhances autofocus, build quality has improved enough to no longer carry the plastic nifty fifty title. I'm going to update the review as I continue to use it, but I can tell you I'm happy with it!

Works great with my Canon M50 and lets me use standard canon 50mm lenses. The only thing to keep in mind is that with this adapter, a 50mm lens is equivalent to a 85mm lens on a DSLR. The product's quality is amazing!

Using this lens on an old 5D Classic and the focus is spot on 95% of the time even at f1.8. the lens is adequately sharp and is leaps and bounds better than the old 50mm 1.8 II in terms of build and focusing. I even like this lens better than the 50mm 1.4 due to the focus accuracy of this lens. this is the best $125 you can spend if you are a Canon shooter and everyone should own one. Hats off to Canon for keeping the pricing where they did. this lens is easily a bargain at twice the price.

Like many others, this was one of the first lenses I purchased as an upgrade to my Canon 18-55mm kit lens. While the fixed 50mm focal length can feel restricting at first, I've found, overtime, that this prime lens is more often than not my go to. I own a Canon 24mm pancake lens as well, and while I appreciate the wider field of view it provides when shooting landscapes/cityscapes, I find that the 24mm is often too wide, making it very difficult to establish any sense of a primary subject. I find the 50mm to be just right for the majority of my shots. I shoot a lot of long exposure night time cityscapes and find that this lens performs exceptionally in low light conditions.Image quality is excellent as far as I can tell. Autofocus is certainly not lightning fast, but it does the job. Build quality feels rather plastic-y (which is why I gave it 4 stars instead of 5), but for the price I don't mind at all. Overall, I really do love my nifty-fifty and understand exactly why it is considered a staple lens for many photographers.

If your looking for a 50mm f/1.8 lens for a canon camera this is the one! 10/10 would buy again

BACKGROUND:Let me start by saying I'm a hobbyist photographer and I've been shooting with a Canon Rebel T1i (500D) for the past 10 years. I was heavily budget-constrained, so I rocked my OG Canon 50mm 1.8 (non-STM) version since 2010. For $150 at the time, it was a fast lens that was affordable to most novice DSLR photographers like myself.After recently getting back into my hobby after a couple years of being tied up with other stuff, I noticed my 50mm was producing softer images than I remember. It had never been dropped or otherwise abused, but it just seemed to be not performing the way I expected. The autofocus was reasonably quick, but very loud and lacking in smoothness and accuracy.BUILD QUALITY:Now that I had a little more money saved up, I decided to purchase the updated STM version of this lens and this is a MASSIVE leap from the old version. The build quality and finish, while still being mostly plastic, feels way more robust. The cheap shiny finish of the old version was gone in favor of a beefier, textured plastic. Also, the lens mount itself is now made of aluminum which fits very firmly against the camera body.PERFORMANCE:After testing it out I can say BOY is this thing tack sharp. With my old lens, I had to shoot at F/2.8 if I wanted anything with usable sharpness. This lens is producing razor sharp images wide-open and the autofocus is extremely quiet, smooth and accurate. It is still audible but you really have to listen for it. As far as speed goes, it doesn't seem much quicker than the old 50mm, but is way more accurate and reliable. The quiet STM focusing makes this usable for video, whereas the old version simply wasn'tJust keep in mind the manual focus still uses an internal motor to move the lens elements. With the camera turned off, turning the focus ring doesn't do anything. Also, on an older camera body like my T1i, turning off the camera wouldn't retract the lens barrel. Now that I've upgraded to a Canon 90D, I noticed turning off the camera will auto-retract the lens barrel all the way, making it suitable to store in a bag without damaging the lens.SUMMARY:If you're getting into DSLR photography and have a reasonably modern Canon DSLR body, this lens is a must-have. For $125 at the time of this review, it's even cheaper than the old lens (especially accounting for inflation), while out-performing it in nearly every metric. Prime lenses are the kings of affordable speed and sharpness, and this lens is right up there with the very best primes you can buy for under $500. If you aren't jumping on the mirrorless camera bandwagon, this is an excellent lens for both full-frame and crop sensor Canon DSLRs.

Exactly what I needed to use the Canon EF 50mm lens with my Canon EOS M50!

What more can you say about the Canon 50mm 1.8? It's perfect!
