I really like extreme lenses. Extremely wide, extremely fast, and extremely long lenses will all allow you to create unique images that stand out from the crowd. When I heard about the Sigma 8-16mm lens I wanted to get my hands on one and start shooting, so I asked my editor if I could borrow one from Sigma for testing. He wanted to know what I was going to do with it, so naturally I told him: take portraits. You might, as he did, find this a little odd—taking portraits with a wide-angle lens, and a very wide lens at that. After all, don’t photographers usually use long lenses for portraits?

Why are photographers taught to use long lenses for portraits? There are four basic tenets behind this reasoning: narrow angle of view, shallow depth of field, flattering perspective, and a comfortable working distance between you and your subject. However, flip these “rules” on their head and you’ll see why I like working with wides: wide angle of view, great potential depth of field, unique perspective, and, oddly enough, working right in your subject’s face. In short, I use the special nature of a wide lens to give my portraits a new and unique look.

Canon offers five different 70-300mm zoom lenses in its product lineup. Why so many? They obviously think this is a popular and practical focal length range and I happen to agree. I even own one of them myself—the EF 70-300mm f/4-5.6 IS USM—but the EF 70-300mm f/4-5.6L IS USM tested is the mac daddy of ’em all. Part of the reason for its high price tag ($1599) is that it’s the only one of the five lenses that is resplendent in white paint (the better for TV cameras to see), making it part of the “L” series. (See “Just For The ‘L’ Of It.”) Canon’s L lenses typically have wide apertures fixed throughout the zoom range but in this case all five lenses in this focal length range have identical f/4-5.6 apertures.

The new Canon EF 70-300mm f/4-5.6L IS USM telephoto zoom lens features two Ultra Low Dispersion (UD) elements for improved image quality and reduced chromatic aberration. It incorporates a floating focusing mechanism for sharpness from close-up (3.9 feet) to infinity plus an Image Stabilization (IS) system that Canon claims increases usability by approximately four stops. The IS system includes a function that allows it to continue to operate even when the camera or the lens, the latter being a better idea, is mounted on a tripod. There’s an optional ($189.95) Canon Tripod Mount C for mounting on a tripod or monopod but I was unable to get one for testing. The lens is dust- and water-resistant and features a Fluorine coating that resists smears and fingerprints and significantly eases lens cleaning, but that doesn’t make me suggest less vigorous lens protection. More later.

Tamron has always been a pioneer in the do-everything zoom lens category and their new AF18-270mm F/3.5-6.3 Di II VC PZD lens is no exception. Don’t be intimidated by those initials—it’s all good stuff—and I’ll get to them shortly. The 18-270mm F/3.5-6.3 is part of Tamron’s Di II family of lenses that are engineered specifically for digital SLRs with image sensors measuring 24x16mm, typically referred to as APS-C. The sensor size of the Canon EOS 50D I tested the lens with measures 22.3x14.9mm so I guess that’s close enough. The 15x zoom range of the lens provides a 35mm focal length equivalency of 28.8-432mm with the Canon EOS 50D’s 1.6x multiplication factor, but that will be slightly different for the Nikon and Sony versions that are also available. Shooting full frame? Check out Tamron’s Di lens series for 35mm film cameras or digital SLRs featuring larger (24x36mm) sensors.

One of the great things about photokina is that you find a lot of “straws in the wind”: not necessarily major introductions from major manufacturers, but intriguing indicators of which way the wind is blowing.
