Денис Степанцов уже писал про эту линзу (http://den-hunter.livejournal.com/215191.html ); вот еще один хвалебный опус на аглицком языке - с ссылками на хорошие фотографии!!!

We are speaking about the legendary Vivitar 90mm 2.5 Series 1 Macro 1:2 lens.  This lens was made for Vivitar by Tokina and is optically identical to the famed Tokina 90mm 2.5 (often called the "Bokina" for its exceptional bokeh).  The Vivitar version has much better build quality than the Tokina version, with a heavier, black, metal body.

The lens goes down to 1:2 magnification (half of life sized).

This Tokina-built macro lens is well-known for:

• Incredible sharpness -- one of Photodo's top ten sharpest lenses ever reviewed.  It received an overall score of 4.6 (see: http://www.photodo.com/product_486_p4.html for details, and scroll down to the bottom of http://www.photodo.com/products.html for the list of the ten sharpest lenses).
• Beautiful, creamy bokeh (rendering of out-of-focus areas). The lens has been nicknamed the "Bokina."
• Sharp not only at macro apertures, but also at f/2.5 and f/4.  With the combination of sharpness and great bokeh, it is an excellent portrait lens.
• Awesome build quality -- solid metal construction (weighs 22 ounces).  This applies only to the Vivitar version; the Tokina variant has less metal and is several ounces lighter (18 ounces).  The Vivitar version has a glossy, black, anodized metal that is not painted.

This lens is for a Nikon AI mount.  It will mount on the D40, D40x, D50, D70, D80, D200, D300, D2x, D3, etc.  As with other legendary lenses of a bygone era, it is not chipped -- so the D40, D40x, D50, D70, and D80 will not meter the lens.  Bodies like the D200, D300, D2x, and D3 can meter with the lens. I use a D80 in manual mode:  set the aperture on the lens, guess at the shutter speed for a good exposure, shoot, look at the histogram in the LCD, and adjust the shutter speed up or down, and shoot again.  The lens is manual focus (which is required for macro).

Sample Photographs

Please click on the link below for a gallery that includes actual photos taken by this exact lens that is on sale, as well as photos of the lens itself.  Hopefully my limited skills can give you an idea of how this lens lives up to its lofty reputation.  I had fun taking these sample photos, and they should demonstrate how this is a high-quality sample.  (Other sellers may show you photos they found on the Internet, taken by another sample of the same model. But below are actual photos taken with the sample that is on sale!)

Here is the lens -- the serial number begins with "37" indicating that it's built by Tokina for Vivitar.  A good list of Vivitar serial numbers can be found at:

History and Comparisons

How the lens on sale compares to other older macros is listed below.  If you are a budding macroholic who loves what older lenses can give you, I recommend searching on www.photo.net for some excellent information.  Probably the most detailed write-up on the Vivitar/Tokina 90mm 2.5 is here:

Comparisons to other macro lenses:

• A popular old macro lens on eBay is the used Tamron 90mm 2.5 Macro (manual focus and a later auto-focus version).  I do not have any hands-on experience with the Tamron to make a personal comparison.  However, my understanding from reading too many Internet forums is that while the Tamron is a very good lens for macro, the Vivitar/Tokina 90mm 2.5 is a superb lens.  The image quality of the Vivitar/Tokina 90mm 2.5 is simply better -- much sharper and with much better bokeh, plus better build quality.
  
  The Tamron's sharpness only scored a 4.2 on Photodo, while the Vivitar/Tokina 90mm 2.5 scored a 4.6. That is a huge difference in sharpness.
  
  The Tamron's bokeh can be harsh. E.g. doughnut highlights, with sharp-edged halos.
• Kiron 105mm 2.8, Lester Dine 105mm 2.8, Vivitar 105mm 2.5 Series 1, Vivitar 100mm 2.8 -- all are the same lens made by Kiron.  I have this lens too, and love it along with my Vivitar 90mm 2.5. 
  
  The primary differences are that the Kiron goes down to 1:1 without any adapter.  But down to 1:2, the Vivitar/Tokina 90mm 2.5 is even sharper than the Kirons at both macro apertures (e.g. f/8 and f/11) and is much sharper at f/2.5 and f/4 (according to tests on Photodo).  The Vivitar/Tokina 90mm 2.5 is simply sharper than the Kirons. 
  
  The Vivitar/Tokina 90mm 2.5 also has better bokeh -- smoother and creamier. The Kiron's bokeh is usually good to very good, but can sometimes be harsh. Sometimes the Kiron injects a yellowish color cast in the photo, while the Vivitar/Tokina 90mm 2.5 has lovely color rendition.
  
  The Kiron was designed as a pure macro lens, while the Vivitar/Tokina 90mm 2.5 is both a superb macro lens and a great portrait/telephoto lens.
• Vivitar 100mm 3.5 -- this is a modern lens that auto-focuses and meters and is available new for about $110.  It is made by Cosina and also sold under brand names like Promaster.  It's a decent macro lens, but it isn't in the same league as modern macro lenses costing 3 to 4 times as much.  It's nowhere near as sharp or contrast-y as the Vivitar/Tokina 90mm 2.5, scoring just a 3.2 in Photodo's tests.  The Vivitar 100mm 3.5 also has weak ergonomics and pretty bad build quality (very fragile, loose plastic).  It's a good "beginner's lens" for 1:2 macro and is priced accordingly.
• Older Nikon AI, AI-S macros -- they're just not as sharp as the Vivitar/Tokina 90mm 2.5, though their contrast is comparable.  The bokeh of the Nikon macros is not as smooth and delicate as the Vivitar/Tokina 90mm 2.5. Unfortunately, the Nikons tend to sell at premium prices, too.
