The perfect zoom pair. 28-70mm f-2.8 & 80-200mm f-2.8


It wasn't long ago when single focal length lenses with fast apertures were the only choices for those wanting sharp and fast optics. Zooms were slow and their quality did not match those of fixed focal length lenses. Lucky for us, those days are over. Newer zooms are getting faster and sharper at more affordable prices. Two of the fast aperture zooms with the most widely used focal lengths are the 28-70mm f-2.8 and 80-200mm f-2.8. No matter what type of photography you do, these two zooms will definitely help you with your photography. Portrait photographers can use the 80mm to 135mm setting of their 80-200mm zooms at f-2.8 for soft background while maintaining sharp images of their main subject. The 200mm setting is excellent for fashion photographers working outdoors for the same reason.  They can shoot at a distance and still remove distracting backgrounds at f-2.8 aperture while maintaining foreground sharpness. The 28-70mm f-2.8 will benefit portrait and fashion photographers as well. Again, the f-2.8 will create soft backgrounds for wide or standard shots at closer range and provides extra speed in low light.

Landscape photographers will love the bright viewfinder of the f-2.8 aperture. Although we rarely use large apertures for landscapes, the extra f-stops are there just in case we need them, for instance, late in the afternoon or low light photography. The 28-200mm will cover majority of your landscape shots.

Indoor and outdoor sports photographers can cover basketball games to gymnastics and even some outdoor sports such as football or baseball. The 80-200mm f-2.8 provides fast shutter speeds and cropping convenience of a zoom lens. The 28-70mm f-2.8 does the same for those lucky sports photographers who can sit behind the line in basketball games or similar sports.

Wildlife photographers can also benefit from these zooms. Most birds and mammals require 300mm or longer lenses, but many larger birds and mammals can be photographed with 80-200mm zooms. Since wildlife photographers also photograph other subjects in nature, many of them have already switched to 28-70mm f-2.8 and 80-200mm f-2.8 zooms.
Why go with a pair of fast zooms when slower versions provide the same focal lengths and still produce good quality images? First of all, let me make one thing very clear. I'm not in any way saying that you should buy a pair of fast zooms if you want to take quality pictures. I have said it before and will say it again here that even slower zooms currently made by major camera and lens manufacturers are capable of producing professional quality images if used correctly. Same is also true with more expensive lenses. Without using good technique, both type of zooms will produce poor images. The main advantage of slower zooms is their size and price. Faster and more expensive zooms are usually sharper when used wide open. They also provide a brighter view due to their faster apertures. Their draw back is the price, size and weight. The decision is really up to you. Do you need the fast aperture of the more expensive zooms? How often will you use these zooms wide open? The answer should be easy. Chances are, you already have zooms covering the focal lengths mentioned here or their equivalent fixed focal length lenses. How often do you need faster apertures? If you answer only a few times, then stay with your current lenses. Otherwise, look into the faster models currently made.
Camera manufacturers versions cost more than generic models. A pair of Canon, Minolta, Nikon, and Pentax 28-70mm f-2.8 and 80-200mm f-2.8 (Canon makes 70-200mm f-2.8) will cost you well over $2000. You can purchase Sigma, Tokina, or Tamron (as of this writing, Tamron does not make 28-70mm f-2.8 zoom) for almost half the price of camera manufacturer zooms and still provide the fast apertures and maintain high quality. Teleconverters can be used with 80-200mm f-2.8, but quality depends on the lens and the converter. Teleconverters generally don't produce good quality images with zooms. With some models however, you can use teleconverters with 80-200mm f-2.8. Canon's 1.4X and 2X teleconverters for example, will fit the 70-200mm f-2.8 EOS with very good quality. Other models which cannot be fitted with matched teleconverters, can be fitted with a generic teleconverter such as Sigma, Kenko, or Tamron. I can't tell you anything about the combinations, because I haven't used any of them with teleconverters, except Tokina 80-200mm f-2.8 and 2X Kenko converter. The combination was acceptable, but I prefer my Minolta Maxxum 200mm f-2.8 and its matched 2X converter. You have to experiment for yourself.

A pair of 28-70mm f-2.8 and 80-200mm f-2.8 may not be for everyone. Those who purchase these zooms, will find them their most often used lenses. The high quality of these zooms at all apertures as well as their fast maximum aperture and focal lengths make them some of the most popular lenses today. Both zooms are also professionally built and will last you a long time.

So, what about the 17-35mm f-2.8 lenses? Aren't these a better alternative to the 28-70mm f-2.8 zooms? It all depends. For general purpose photography, 28-70mm focal lengths come in more handy. I'm talking about those millimeters between 35 and 70. If you do mostly landscape photography, then you might need the wider 24mm or even 17mm focal lengths. Otherwise, 28-70mm will be a better choice. I will discuss the 17-35mm zooms which are becoming popular in a future article.

Features:

  • Special low-dispersion glass for high image quality
  • 28 to 70 mm focal length
  • f2.8 maximum aperture
  • Inner focusing system allows add-on hoods and filters

This is the world’s smallest, large and constant aperture zoom lens and is ideal for digital SLR cameras. The power layout of the lens is specially optimized for digital SLR cameras, and Super Multi Coating gives superb color performance whilst cutting down flare and ghost.

Two SLD elements and four aspherical lenses provide the ultimate correction against distortion as well as all types of aberration, especially spherical aberration. Its advanced optical design ensures high performance throughout the entire zoom range.

The use of aspherical lenses in the construction of this lens not only corrects aberrations but also produces a very small and lightweight lens design. Its compact, yet robust, construction has an overall length of 87.2 millimeters (3.4 inches), maximum diameter of 74 millimeters (2.9 inches), filter size of 67 millimeters and weight of 510 grams (18 ounces). It has a minimum focusing distance of 33 centimeters (13 inches) at all focal lengths and a maximum magnification ratio of 1:4.4 which is very convenient for close-up photography.

The inner focus system allows the lens to be focused without rotating the front element, therefore a Petal-type hood and circular polarizing filters can easily be used.
