Some M-Mount Field Curvatures
I haven’t posted very much lately. We’ve had some new equipment installed and we’ve been doing a LOT of testing as we develop our new database of lenses on the optical bench. As the database fills out I’ll be posting more than ever, just because a lot of this stuff is just fun. Today’s post is…
HandeVision IBELUX 40mm f/0.85
*Image credit Lensrentals.com* ## Preconceptions I try to start these articles by putting my preconceptions out there first. Every reviewer or blogger has them, they affect our opinions, and you have a right to know them. So I’m writing this introduction the day before our first copies arrive. The…
A Useful Metabones EF to Black Magic Pocket Camera Article
Way back in the old days, before everything was plug and play, you could buy a computer and accessories from one manufacturer and be certain it would all work together. The cool kids, though, would mix-and-match different pieces and end up with a better system that could do more things than any one…
Of Course We Took One Apart
## A Look Inside the Canon 16-35 f/4 IS This is a Geek Article. Many of you don’t understand the term ‘Geek’ properly, so perhaps this will help. As the graph shows, if you aren’t both intelligent and obsessed with photo gear, you won’t enjoy this article. *I’ve tried hard to find whom to credit…
Canon Wide-Angle Zoom Comparison
* Left to right: Canon 16-35 f/2.8 II, 16-35 f/4 IS, 17-40 f/4. Can you spot the one with the wrong hood?

A New Old Lens
Like a lot of photo history buffs, I’ve been quite excited about Lomography’s new iteration of the Petzval lens in 85mm focal length. For those of you who don’t know about the Petzval lens, I wrote about it a few years ago. It really has a rather a fascinating story. Since writing that article,…
Sensor Stack Thickness Part III: The Summary
Well, I have to admit this has been a fun series. I’ve learned a whole lot. That’s what makes this so fun — I get some results I don’t understand, get some help figuring out what is going on, and before I know it, I’ve learned something that explains other things I haven’t been able to understand.…
Some Holiday Lens Mutilation
A couple of weeks ago I got an email asking if we would be willing to take some lenses, remove the electronics, fix the aperture wide-open, and permanently lock them at infinity focus. It seems the person who needed this done was having trouble finding a legitimate repair shop or service center…

Geeks Go Wild: Data Processing Contest Suggestions
A couple of years ago I gave a talk on the history of lens design at the Carnegie-Mellon Robotics Institute. The faculty members were kind enough to spend the day showing me some of their research on computer-enhanced imaging. I’m a fairly bright guy with a doctorate of my own, but I don’t mind…
