This lens absolutely blew me away. I have the Canon f/1.2L and used to have the f/1.4 and simply got this to see if the STM version was an improvement from the original nifty fifty. The lens now has a metal mount, which gives it an all better look and a bit more sturdiness in the hand. It is still pretty "plasticky", but you're paying $125 for it, what more do you want? Performance wise I can 100% guarantee you will see little to no difference when compared to the f/1.4, definitely not a $200 difference! The only difference is that you get not even half a stop more of light. If you're teetering on whether to get the f/1.4 or this lens. Get this lens. It may not look as pretty or aesthetically pleasing as the f/1.4, but you will get the same results, and they are stunning. I won't go as far to say it's better than 1.2L, but I don't think you'll find you need any need to upgrade, whatsoever, unless you have an occupation that calls to. Don't forget to perform micro adjustments with your lenses, this back focused so I had to adjust it to -5.Update 6/26/18: I have had this lens for 2 years now and still stand by everything I said above! Because this lens is so light I always have it in my bag and a lot of the time, on my camera. Crazy versatile and still sharp 2 years later.

Good quality glass ,for the price was perfect....use it for my 24mm 1.4 lens .

I've used this with my 35mm f/1.4 E-Mount . By far, this polarizer has not came off my lens when i took it out for travelling to Hawaii. It gave my shots more contrast, darkens the highlights to the point where I can use the image and of course, see through reflections. As a polarizer, it does what most polarizers do, I definitely would recommend this filter!Highlights:- Tiffen helps with maintaining the sharpness- Blocks reflections- Ups the contrasts in your shots and reduces highlights

Works on my Fast lens 1.4 / 2.8But not on 3.2 and 4/5/6/

I recently got into photography and purchased a camera "bundle" of the Rebel T6. The additional lenses in that bundle were apparently just a bad joke, but overall I was happy with the purchase. However, I still needed some new lenses for the shooting I want to do (concert photography/videography), so I started to research some more lenses. I was initally looking at getting the EF 50mm f/1.4, which is around $350, but decided to keep looking further, and eventually I came across both this lense, the EF 50mm f/1.8, and the EF-S 24mm f/2.8, which are both around $125. After reading several reviews I decided to go with the two cheaper lenses, and I am extremely happy I did so. While I may have been happier with the shooting of the f/1.4 to the f/1.8, I do not think it would have been an ideal lens for videography. That being said, I freaking love this lens. I've gotten to play a little bit in low light settings, though I have not been to any concerts with it yet. These are some shots from it, haven't played with them in Lightroom yet. I honestly love the way some of the photos look so much with just the lens, I probably won't even mess with editing them.Tl;dr - If you were torn on spending the extra $200 for the f/1.4; unless you're a professional, I would say save yourself the money and get this lens, it's amazing.

For only $150, you get a very high quality portrait lens (it even has a metal mount). The difference between this one and the f/1.4 does not look to be worth getting the 1.4

Very happy with this lens. There is the 1.4 model, but at twice the price or more, this one gives the effect I was looking for, and I wonder if the higher-end one would bring too much of the blur effect.

Love this lens. Will update 1.4 shortly but love this lens as a starter.
