We’ve done a pretty good introduction to the field curvatures of 24mm, 35mm, 50mm, and 85mm prime lenses. We made a little bit of comparison with bargain primes and zoom lenses at 35mm. This post is going to assume you are familiar with those previous posts. (Yes, I know the reality is most people read […]

We introduced evaluating field curvature with 35mm f/1.4 lenses, then looked at how those differ from slower 35mm primes and zooms at the same focal lengths. Then we got into some practical stuff, showing how field curvature gives you useful information for 50mm lenses. Today we’re going to look at 24mm and 85mm prime lenses for a couple of […]

Just so you know, my original title was “Lens Disassembly is a Complicated Profession. Don’t You Agree?” The editor said nobody would know what the post was about. But I promise, you’ll see by the end of this; lens disassembly is a complicated profession. We were interested in this disassembly, and by interested, I mean both […]

In my last post, we looked at how the field curvature of some really excellent 35mm f/1.4 primes affected what happens when we stop down the lens. The takeaway message is that as you stop down, things change a bit differently with the different lenses, but by f/5.6 they were similar. Still slightly different, but […]

Someone remarked the other day that sometimes our equipment gets used in the recording of the various “Find the Ghost” or Check-Out-This-Haunted house TV shows. Someone else became concerned that if our gear was exposed like this, maybe some of it came back haunted or contaminated by malevolent spirits. Aaron and I, since we develop all the […]
