This is a _fantastic_ blog for camera/lens nerds. Highly recommend, very happy to see Roger Cicala get some love here. It's like my nerd-planets aligning, HN and Lens Rentals. If you read through the Lens Rentals archive, you'll find the absolute best (bar none) public discussion of lens build quality, imaging optics, and generally user-friendly discussion of very technical-but-practical optics issues. And it gets technical enough that there's no fluff. Also, you'll also get the kind of war stories you only get when you see thousands of copies of lenses, abused in ways your imagination thankfully can't grasp. Required reading if you're an optics nerd. Or if optics is one flavor of your nerd (for me, it is). I've used their service in the past, though only briefly (I think I've given Roger less than $1k total). I come for the blog and MTF charts, mostly.
