I am a big fan of Canon mirrorless cameras and lenses. The 135 is a beast of a lens; buy one now.

I have recently acquired this lens and decided to write this review based my thoughts after testing it and comparing the results from my RF 85MM F1.2. I have always thought that my RF 85mm F1.2 lens was one of the sharpest lenses that Canon produced even thou my 28-70 mm F2 is great as well. This lens is as good as the 85mm F1.2 and the only difference is the focal length. The picture quality is stunning, and the focus speed is quick. I am surprised that Canon is not charging more for this lens because it is that good. Without hesitation I would recommend this lens to anyone that could afford it, and you will not be disappointed.
