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...

Long considered the focal-length sweet spot for macro work, the 60mm focal length of the new Tamron 60mm f/2 lens ($569 MSRP) converts out to 96mm for Canon and 90mm for Nikon APS-C D-SLRs.

Because of the increasing number of D-SLRs with full-frame sensors, Tamron is upgrading several of their multi-platform lenses to the Digitally Integrated standard. The most recent model, the 70-200mm f/2.8 Di, is optimized for D-SLRs regardless of the sensor size but also provides outstanding results with 35mm SLRs. This zoom has benefited from several improvements, including closer focusing...

For the first time, Tamron has incorporated an Ultrasonic Silent Drive, or USD, with full-time manual override in this zoom lens, making it a competitive technology with Nikon’s Silent Wave Motor, Canon’s Ultrasonic Motor (USM), and Sony’s Super Sonic wave Motor.

The 90mm f/2.2 Leitz Thambar is one of those few lenses that is always prefixed "legendary." Designed primarily for portraiture, it was introduced in 1935 in Leica screw fitting, 39mmx26 tpi. It seems to have been discontinued during World War II, although there are scattered reports of...

If photography is your pastime, you can afford to indulge in toys. If it is your occupation you tend to be more selective about what you spend your money on; toys are an extravagance--you couldn't afford 'em when you were struggling, and you don't need 'em now that you have a client base which likes your style.

But what if a toy is also...

Like modern automobile engines, most digital cameras equipped with interchangeable lenses seem to have most of their power or torque at the high end of the focal length scale. In digital SLRs with smaller than full-frame sensors, your 300mm might be a...

With the recent addition of the 150mm f/2.8 autofocus lens, the line-up of telephoto or long focus optics for the Pentax 645N camera is nearly complete. When the 645N was first introduced, Pentax promised that they would issue a...

If a picture is really brilliant, you don't have to worry about grain or sharpness or anything else: to quote Mike Gristwood, late of Ilford, "How much good would it do you to know the technical details of any one of Henri Cartier-Bresson's pictures?"

By the same token, if a picture is really bad, no amount of technical brilliance is going...

As soon as I opened the box I was in hyper-drive. There before me was one very impressive piece of optical gear. Made by Sigma, this new telephoto lens includes useful focal lengths from the ever-popular 300mm to a mind-boggling 800mm. For photographers...

There are plenty of other good (but significantly slower) 21mm and 24/25mm lenses on the market, almost all cheaper, smaller, lighter, and exhibiting less distortion than the two under discussion here.

After last year's exhaustive study of all things Russian, I thought I was done with Kiev equipment. While I had given up on most things Ukrainian as everyday shooters, I did still have a fine Kiev 60 body and a handful of Kiev lenses...

As soon as I heard about it, I wanted to try the f/2 28mm Zeiss ZF lens; ZF, for those unfamiliar with the current Zeiss line-up, is their superb line of Nikon F compatible manual focus lenses, as distinct from ZM (Leica M compatible) and ZV (classic Hasselblad compatible).

All of the ZF series are also available in ZK (Pentax K bayonet compatible) and a few, though apparently not...
