I'm Roger and I am the founder of Lensrentals.com. Hailed as one of the optic nerds here, I enjoy shooting collimated light through 30X microscope objectives in my spare time. When I do take real pictures I like using something different: a Medium format, or Pentax K1, or a Sony RX1R.

When we optically tested the Sony FE 135mm f/1.8 GM we were mighty impressed. Then I threw up in my mouth a little when I read a couple of reviewers comment on the build quality. Because holding a lens gives you not the slightest idea about the build quality. So I was excited when a 135mm […]

Again, we’re not going in any particular order, other than what we have handy and what fits reasonably into a single post. Since these are among our most popular cinema lenses, we do generally have at least a 10-copy set for each. […]

We’ve completed the MTF postings for all of the photo prime lenses. Now we’re going to start with the Cinema primes. For a lot of those that also have a photo version, the optics should be identical. That’s not always the case, however. Plus, the people interested in Cinema lenses aren’t usually the ones interested […]
