Quick answer The Canon EF 50mm f/1.8 STM Lens scores 9.6/10 with us. Amazon owners rate it 4.8 out of 5 across 18,525 reviews, above the 4.2 average of the 647 products we track in Cameras. It was listed at $169.00 on Amazon when we last checked in September 2026.

Product Description The wide f/1.8 aperture lets in more than 8x the amount of light compared to the standard zoom lens that is provided with your EOS. This results in sharper images with less motion blur and reduced need to use flash in dimly lit conditions so you can easily capture the atmosphere of a low light environment. The 50mm focal length allows you to fill the frame with your subject from a comfortable distance making it a great lens for portraits.

A similar perspective to the human eye and its compact size make the EF 50mm f/1.8 STM a great everyday lens to always carry with your EOS camera. The near-silent STM (Stepping Motor) technology focuses extremely quickly when shooting photos, so you can react suddenly to capture fleeting moments. Creating high quality movies is easier with STM as it delivers steady and quiet continuous focusing, so your movies are smooth, and soundtr

    A massive upgrade from the 50 1.8 - if you have one, it's time to upgrade :)

    BUILD QUALITY: Let’s first talk about the build quality of this new lens. The 50 STM has had a massive upgrade in this area, and feels absolutely fantastic. From the moment I picked up the lens, I knew that it was a complete redesign from the old model, and it sure needed it.On the rear of the lens we now have a metallic mount, something I’m so glad to see. Moving up from the plastic mount has increased it’s weight slightly, but also hugely increases the longevity of this lens. On the front we’ve now got a 49mm filter thread, which is even smaller than the old 52mm thread.And even the little t

    Why This $150 Lens Improved My Photos More Than My $800 Lens

    I originally bought the Canon EF S 17 to 55mm f2.8 for my Canon Rebel because this is what many beginners assume when getting into photography. You think the path to better photos is mostly about buying a more serious and more expensive lens. And to be fair, the 17 to 55 is objectively a very good lens. It is sharp, well built, and widely recommended.The strange thing is that using it did not dramatically change the way my photos looked. It felt like a nicer version of the same zoom lens experience I already had. You stand somewhere, twist the barrel closer or farther, take the picture, and mo

    Highly recommend

    The Canon EF 50mm f/1.8 STM is an affordable, lightweight lens that’s great for portraits and people photography. It creates sharp photos with a beautiful blurry background, performs well in low light, and pairs especially well with the Canon Rebel T7. Overall, it’s a great lens for beginners and a good upgrade from the standard kit lens.

    Possibly the best value in all of photography

    Ah, the “nifty fifty”! This is without question the best-selling lens from Canon, maybe even of all lenses. Its high price to performance ratio is the reason for this. It can be useful on both crop and full frame, and should probably be every beginners first upgrade lens, which I will discuss more in the review. As with all WOFG reviews, I will cover the pros and cons, offer advice for how to use the lens, and give some suggestions at the end.Let’s pro/con this thing!Pros1. Price – Right at the top of the list is the price, typically 125 USD, though sometimes it can be had new for as little as

    A HUGE step-up from the original EF 50mm 1.8 lens

    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

    Amazing lens! Awesome bokeh! More zoomed in than expected.

    I love this lens! It's been on my wishlist for a very long time- I could never get tired of the creamy bokeh blurriness that this lens provides! Unfortunately, I had to return my 50mm because it operated very similarly to my 85mm lens. It was much more zoomed in than I expected, and I realized it was because my Canon Rebel T7i is not a "full frame" camera or something-- so that's why it was just a little bit less zoomed in than my 85mm lens. I tried to get wide angle lenses that could fit on top of my 50mm to make it a wider image, but I just couldn't get the right size- none of the lens adapt

    Wonderfully sharp, fast focusing and petite

    HIGHLIGHTS: excellent image quality, compact form factor and affordable pricing, but with few concessions in build and AF performance.CONSTRUCTION: Slightly smaller and heavier than the prior model, EF 50 1.8 II, aka nifty-fifty, but with significantly better build quality. Improvements include metal mount, sturdier barrel and AF/MF switch, larger focus ring, grippy matte finish and stepping motor (STM). Unfortunately, it has an odd filter size, 49mm, rather than 52 or 58mm common to small Canon lenses.OPTICAL QUALITY: It's the same optical formula as the nifty-fifty, but with tweaks to lens c
