Lens Reviews

There are two types of fisheye: circular and diagonal. The Rokinon 8mm f/3.5 Aspherical Fisheye Lens is of the diagonal type, delivering a rectangular image with cropped-sensor lenses. The lens I worked with is designed for the Nikon DX (APS-C/cropped) sensor. The APS-C version provides a 180-degree field of view. Other versions are available for other “cropped-sensor” interchangeable-lens cameras, including Micro Four Thirds. My tests were conducted using the Nikon D300.

There are a number of new lenses, including those for “full-frame,” Micro Four Thirds, and “mirrorless” compact system cameras debuting this year, listed in alphabetical order. Here’s a sampler, with a sprinkling of filters thrown in for good measure. We’ve shown prices when available at press time—if not, check the websites of the companies for updates.

Every year the Technical Image Press Association (TIPA), a worldwide association of photo and imaging magazine editors, meets to pick the Best of Class in a wide range of photo categories. As the sole US member of the association, Shutterbug joins editors from Europe, Asia, and Africa in the nominating, judging, and selection process. One of the most exciting aspects of photography today is the constant advancement of technology and design, and this year’s Top Products reflect that spirit and those accomplishments, including new categories of Video D-SLR and Mobile App. Editor George Schaub joins all fellow TIPA members in congratulating those selected to receive the prestigious TIPA award.

There are three main elements in depth of field—focal length, aperture, and distance to subject—and depth of field is a very important part of a 2D photograph. It’s how we judge scale (or are fooled by it), how we note the importance of certain subjects within the frame, and how we define content and context in the scene. With these three controls, and using various points of view, it seems we have infinite variations to choose from, and that’s part of the creative play of photography. Now you can add a fourth element to the mix—tilts that range from mild to extreme and that create “slices” of sharpness within the frame. The tool that helps us create that effect is the latest optic from Lensbaby, which they dub the Edge 80.

There are two general classifications of lenses that define how you use them in the field—zooms and single focal length, the former being a variable focal length lens that has many convenient advantages, and the latter being a single focal length that, in the group we’re covering here, is what’s known as a “fast” lens. Fast doesn’t mean that it focuses quicker than its zoom cousins, though it might—it usually means that it offers a wide maximum aperture, anywhere from f/1.2 to f/2.8, and that aperture stays put, unlike some zooms where the aperture varies by going narrower as you zoom into longer focal lengths. And to help refine the group we’re covering here we’re also topping out the focal length at 50mm, which makes these lenses prime for street and low-light photography, candid and photojournalism work.

The 85mm VR Micro Nikkor ($529.95, MSRP) benefits from next-generation VR II technology and is stated to deliver usable results at up to four steps below the optimum shutter speed. Keep in mind that we’re dealing with a DX-dedicated lens for an APS-C sensor camera (like my D300). So the optimum shutter speed when shooting handheld and without VR on translates into 1/(Lens Focal Length x Sensor Factor), or 1⁄85mm x 1.5, or 1⁄125 sec (rounded off). (Because this is a DX lens and this is Nikon, the multiplication factor is 1.5, so the effective focal length is approximately 128mm.)

Having shot with numerous Lensbaby products over the past years I’ve almost grown accustomed to their ingenious approach to image-making tools and the equally ingenious way in which they approach product design. I do have to admit that one area in which I took less advantage than I might have was in aperture control and how that affected depth of field in my Lensbaby shots, more from laziness or simply forgetting about changing the aperture inserts as I got involved in the shoot. (For those who have not shot with Lensbaby optics you lift in and drop out, via supplied magnetic wand, the various aperture rings corresponding to the diameter of the desired aperture for the optic in use.) Now, this impediment to getting the most from the optics (admittedly, again, my own) is removed with their latest product, the Sweet 35 Optic.
