A good 135mm f/2 lens can be a very versatile optic for a variety of situations. This excellent video takes a look at one such lens (and a rather affordable one), the Samyang 135mm f/2 ED UMC.
Coming to you from Micael Widell, this great video takes a look at the Samyang 135mm f/2 ED UMC lens. I have always been fond of 135mm f/2 lenses, especially since I find 85mm a bit too short for a lot of portraits for my taste, and they are a great way to get a different look from more standard portrait focal lengths, plus they offer good low-light performance at a medium telephoto length, making them versatile in a variety of situations. The downside to the Samyang offering is that it is manual focus only, but if you are using it on a mirrorless camera, you can take advantage of the myriad of manual focus assistance options to use the lens more easily. Of course, if you are shooting fast action, then it might not be the right choice, but if you are looking for a sharp, contrasty lens with a wide maximum aperture, the Samyang looks like a good choice at a very affordable price. Check out the video above for Widell's full thoughts on the lens.
