In the first noteworthy change to the Leica M mount since its introduction back in 1954, all Leica M lenses delivered to dealers starting on July 1, 2006, will have a 6-bit digital black and white code applied to the bayonet ring. The physical dimensions and mechanical specs of the venerable M mount will remain exactly the same, so both coded and non-coded lenses can be used on...

This fairly large (6.5" long, 3.3" in diameter), reasonably lightweight (32.5 oz, including removable tripod collar) macro tele covers the 24x36mm format in film or digital as well as the smaller APS-C digital format. The Di (Digitally Integrated) designation indicates that it's "optically designed for digital SLR cameras." To translate the remainder...

My first macro lens was the popular Nikon 60mm Micro-Nikkor. Good move, I thought, as the 60mm focal length could double as an all-purpose lens for a variety of assignments. Trouble is, when I started to get into more and more 1:1 (life-size) work, I only had 21/2" of working space between the front of the lens and my subject. The 105mm was next, sharp as a tack but again...

If I could, I'd spend all my time hunting down bugs and lizards and any other critters small enough to fit inside a macro lens. Simply stated, I love macro. So I couldn't wait to put the new EF-S 60mm f/2.8 Macro lens through its paces on my Canon EOS 20D digital SLR.

As you may already know, EF-S is Canon's designation for APS-C-dedicated lenses...

Although many zoom lenses are labeled as "macro" that designation generally refers only to moderately close focusing ability. With a few exceptions, such zooms are not adequate for a dramatic frame-filling image unless the subject is quite large. (A few tele macro zoom lenses are capable of much higher magnification, however.) On the other hand, true macro lenses can...

Tamron's AF18-200mm F/3.5-6.3 lens is part of their digitally integrated (Di II) lens series that's designed for digital SLRs and is not recommended for use with cameras having image sensors larger than 24x16mm, or 35mm film cameras. The lens is available in Canon EF, Konica Minolta AF-D, Nikon AF-D, and Pentax AF mounts and is maximized for smaller-sized imaging...
