One of the favorite lenses among news photographers, a 70-200mm f/2.8 or 80-200mm f/2.8 zoom also appeals to many serious photo enthusiasts. Although large and heavy, lenses of this type offer several benefits. Their very wide maximum aperture allows for faster shutter speeds than the more typical f/4.5-5.6 zooms, great for low-light or action photography at lower ISOs (film or...

While searching for a new portrait lens I saw Sigma's APO MACRO 150mm f/2.8 on their website. But wait, you say, this is a macro lens, not a portrait lens! Here's my thinking: Any portrait photographer out there worth his light meter will gladly extol the virtues of a long, fast lens for portraiture. The reasons are simple--limited angle of view to get rid of...

If you ever want a unique point of view try a "fisheye" lens. Like looking through a door peephole (which in fact is a "fisheye" type) this order of lens sacrifices linear correction in favor of a very wide angle of view. Originally made for creating "full sky" images when pointed straight up, they had long ago been adopted by photographers for...

The news last week that Canon’s rare, 1200mm super telephoto lens was on sale again reminded us of another giant piece of glass that generated tons of buzz when it was introduced in 2008: the Sigma 200-500mm F2.8 APO EX DG.

There's one lens that's part of my 35mm/digital SLR system that I have used longest, continuously now for about 40 years. It is a homemade single-element soft-focus lens inspired by the Rodenstock Imagon lens for large format cameras. There are more images in my library of photographs made with this lens than any other. But why in this modern, high-tech world of...

If, like many Shutterbug readers, you have a film SLR camera plus several interchangeable lenses, you might be wondering if you can use those lenses with your new D-SLR camera of the same, or even different, brand.

You read a lot today about extreme sports. Extreme kayakers paddle previously unexplored rivers with class VI (considered impassable) rapids, extreme mountain bikers make 70mph descents of world class downhill ski courses, and even the relatively sedate...

If you go way back you remember the first telephoto zoom lenses as heavy, ungainly things that were often more trouble than they were worth. Travel a bit ahead in time and check out the wide-to-tele zooms, and you get the same thing, with...

The best-selling zoom lens in history, Tamron's 28-200mm debuted in 1992. Since then, it has been redesigned and upgraded in 1996, in 1999, and again in 2001. This most recent (fourth-generation) model benefits from significant downsizing...

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.

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 70-200mm focal length has been the standard tele-zoom choice for many years, offering near normal to a good tele range that suits many practical purposes. Yet, quite a few stock-in-trade 70-200mm lenses had been slow or lost significant aperture as soon as you left the shortest zoom setting, making them a real challenge for handheld, low-light, or even max focal length shooting. Certainly, improvements in sensors and processors in terms of the high ISO/image quality ratio have helped. If you’re too slow on shutter speed with a variable aperture zoom you can always jack up the sensitivity. But that’s not always a great choice and it seems to force you to compromise image quality just to make up for the lens losing “speed” just when you need it most.
