Research, kept where I can point at it.

Comparisons, measurements and technical rabbit holes — written up properly so I can cite them in a video and you can check the working. Every page says when it was written and under what conditions.

What 59 lenses say about paying more

August 2026

Every full-frame 35mm prime and standard zoom on E-mount, graded and priced. Where the money goes, which cheap lenses are secretly good, and the part where the data contradicted my own shortlist.

About

This is where research goes once it outgrows a note to myself. Most of it starts as a buying decision or an argument I couldn't settle, and ends up long enough to be worth keeping.

If you got here from a video, the page you want is linked in the description. Numbers here are mine unless stated, and the conditions are always written down — if a page doesn't say how something was measured, don't trust the number.
