After two years of testing, renting, buying and selling just about every level of Nikon and Canon lenses and cameras, I have learned quite a bit about what works and what doesn’t. Pretty much you can’t go wrong with Canon or Nikon, and just about everything they make is top notch.

Here’s a question I get asked about 15 times a week: “How can I get the dust out of my lens?” The right answer is you don’t. All lenses have dust in them and it doesn’t affect the images at all 99% of the time. Even if you clean it all out, it will be back after you use the lens a few times.
There are occasionally times that large dust specs very near the rear element are visible in an image, though. There also is the very real issue of resale value; a dusty lens tends to bring a lower price than one without much dust. The right answer in these cases is “send it in for factory service, they’ll disassemble it and clean it.” Doing it yourself is risky.

Here’s an awesome DIY project put together by photographer and student Cormac Relf. In a recent fit of DIY-ness Relf decided to create his own homebrew lens.

Originally produced for the US military in WW2, the Kodak Aero Ektar 178mm f/2.5 is a large-format monster of a lens. Mounted in bombers, facing down at Europe, this lens was sold to the US government for the price of a family car. It found its way into military surplus after the war, and was widely used in journalism and by professional photographers.

Late last year, we shared a video in which a photographer tested the radioactivity of an old Pentax 50mm f/1.4 lens that is really popular with film photographers. But that is far from the only lens you have to worry about when it comes to radioactivity.
Camerapedia lists 54 lenses that have been reported as radioactive and that, if you use them often enough, you may want to take note of.

Remember that giant wooden Nikon 14-24mm hanging lamp we featured back in February? The designer, Spanish studio Monoculo Design, is back with another interesting piece of photography-inspired home decor — this time for Canon shooters.
The latest creation is a stool that’s designed to look just like a Canon 8-15mm fisheye zoom lens.

Wow. The rumor of a new Sigma 18-35mm f/1.8 lens we shared earlier today has just been confirmed by Sigma. The company has just officially announced the lens, which is the world’s first lens that offers a fixed f/1.8 aperture throughout its zoom range. That’s a pretty big deal.
