Lens Reviews

There’s something about a fixed focal length lens that brings the photographer out in me. It forces me to move in and back from compositions without resorting to a zoom. Yes, there are times when a zoom is most appreciated—especially the fast constant aperture zooms now available—but a prime puts me in a mindset that a zoom has yet to match.

The difference between a “constant” aperture zoom and other standard zooms is that when you increase the focal length on the standard zoom the maximum aperture narrows. This might make the difference between being able to hand hold or not when zooming in, and may indeed force the use of higher ISOs. Known as “fast” lenses, constant aperture zooms are pricier and bulkier than their variable-aperture counterparts. And to sweeten the pot, we’ve seen more and more fast lenses with built-in image stabilization, which gets you even more low light and steady shot capability.

The Sigma 85mm f/1.4 EX DG HSM lens (average price: $969 on various Internet sites) is designed for full-frame cameras; with an APS-C multiply by your usual factor. At about 25 oz, I’d describe the lens as substantial, but not hefty. One of the reasons for the weight is the build—11 elements in eight groups, including the use of SLD glass, Sigma speak for Special Low Dispersion. The big chunk of glass on the end requires a 77mm filter. As to handling, Sigma has gone from their black “crinkle” finish to a smooth black rubberized finish that feels great to the touch. It’s plastic, not metal, but based on my experience with previous Sigma lenses, I’ve found them to be built to professional standards and can take a lot of abuse.

Out of all the telephoto focal lengths, the 400mm is my favorite, so I looked forward to Canon’s updated 400mm f/2.8L. At about $11,499 list price (slightly less on searched street prices) it’s for those who absolutely need a fast, fixed focal length lens in their still and/or video work, and that’s work that pays well.

The new super wide angle Distagon T* f/2.8 15mm lens for Canon and Nikon mounts is neither lightweight nor inexpensive (1.6 lb for Nikon, 1.8 lb for Canon mount, $2950) but what you get from this manual focus lens is exceptional image quality and facility that is perhaps unmatched by any other lens in its focal length class. With a 95mm filter thread and integral and fully compatible lens shade, the lens offers an extraordinary 110-degree angle of view that is pleasure to work with on a wide variety of subjects. The fast f/2.8 aperture is matched on the narrow end by a minimum aperture of f/22, which at 15mm means there’s potential for extraordinary depth of field effects using the 10-inch closest focusing range. While decidedly not a portrait lens, the 15mm is ideal for landscape, street photography and creative advertising work, as well as architectural and urban photography, as I discovered in mybrief time working with it.

Every lens maker offers standard types of lenses: wide angle, normal, and telephoto zooms plus several primes in popular focal lengths. Although highly useful, these lenses alone do not represent the breadth of offerings available. Hidden away within the lineups of many lens makers are specialty models which, even if they aren’t suitable for one’s purposes at any given time, are fascinating not only for their unique qualities but also because they might someday be the perfect tool for a specific shooting situation.

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.
