Roger Cicala knows a lot about lenses and pushed lens manufacturers to have better testing and quality, he created https://www.lensrentals.com/ https://www.lensrentals.com/ because he got sick with low quality checks of lenses:
When I started Lensrentals I had a lot of conversations with service centers that went like this. Me: "That lens you repaired still sucks". Person at service center: "No, it’s within specs". Me: "What are the specs?" Service center: "We can’t tell you". One day, after I raised hell with a factory service manager, he patted me on the head and said, “testing lenses is complicated; you don’t have the background to understand.”
Any of you who has ever seen a physician after someone says something like ‘you wouldn't understand; it’s complicated’ knows what happened next. I had no option but to spend a couple of years buying testing equipment, offering internships to really smart optical engineering students, and developing a lens testing center and methodology that was as good as anything in the industry.
He is also capable of writing about hard topics in a way that most people can understand them.

- salimmadjd 5y agoHis lens tests are excellent. The lens rentals blog is the best place to find them [0]. If you're in market for high quality lenses, lens rental blog is a great resource. I also like cameralabs' lens tests [1]. Not as scientific as lensrentals, however, it has real samples and images of charts for comparison, so you can get a sense for what the different resolution means in image resolution. It also tests things beyond resolution. Such as out of focus rendering, coma, sun stars, etc. [0] https://www.lensrentals.com/blog https://www.lensrentals.com/blog [1] https://www.cameralabs.com/camera-lens-reviews/ https://www.cameralabs.com/camera-lens-reviews/
- subhro 5y agoHe does break down technical stuff is average Joe language. But, one this that does tick me off is his lens analysis does not consider larger formats.

- salimmadjd 5y agois that because the limitation of his testing insurgents?
- subhro 5y agoProbably, or maybe because medium format and large format lens reviews does not get him enough traffic/sponsorships/street-cred.

- Andrex 5y agoThank you for the LensRentals.com link! I've been using BorrowLenses.com and been happy with them, but the more sources of equipment the better. LR has a better selection than I expected too.
