Canon RF 135mm F/1.8L IS USM Reviews
One of the top 2 lenses Canon produced
By DMC Photography
Rated 5 out of 5

I purchased this lens used to save a couple hundred bulks but was not disappointed at all. I have been reluctant to buy this lens despite the great reviews. I always thought that the Canon RF 85mm F1.2 was the sharpest lens Canon produced, but after using this lens I was wrong it is just as sharp as my 85mm F1.2 with a little longer distance. My 28-70mm F2 is my best versatile lens, which is sharp as well, but I would have to give the edge to my 85mm & 135mm for sharpness because they are scary sharp
Great Indoor Sports Lens

Love this lens for indoor sports! Being an amateur photographer and grandpop, I use it for volleyball, gymnastics, and cheerleading pics all shot from the stands and the results are fantastic and sharp! Great lens! I’m waiting for Canon to release a new 200mm prime and hopefully won’t be much heavier than this piece of perfection!
