85mm f/1.4 Manual Focus Optical Lens by Bower.
A serious portrait length designed in combination with a huge f/1.4 maximum aperture size. This 85mm lens is really nice for FX DSLR full frame or SLR film cameras and additionally works on APS-C DSLR cameras, and the only
limitations to the operation of the camera is manual focusing only. it is available in mounts for Nikon, Pentax and and electronically communicates the aperture of the lens to the camera. For Canon, and Sony/Minolta there is no communication with the camera and must be set in
'M' or 'A'.
With a 35mm focal length equivalent to~127mm and the huge f/1.4 orifice, the 85mm lens opens photographic doors you'll never obtain with an ordinary zoom. You'll be able to shoot close portraits of entertainers on darkly lit stages with only spotlit faces, and background lights turn into soft torrents of low-contrast hues. Because of the huge f/1.4 orifice, there's enough illumination to stop subjects in ther tracks. Or give it a spin in brighter situations using a fast shutter and low ISO to create great images of people in out in front of blossoming trees, with flowers in the background almost resembling paintings. It's hard nailing manual focus right on at f/1.4-2.0 It's also difficult for an auto focus system), although you'll improve with practice, and you'll soon be shooting many stand out images.

If you can get by with f/1.8 or perhaps f/2, I'd suggest the
Nikkor 85mm f/1.8 AF-D
which is available for just a a little more money than the Bower 85mm, features
autofocus and a superior mechanical quality. For pure manual focus, I prefer the classic Nikon manual focus AI-S,
85mm f/2, still the smallest Nikon 85mm and sells for less money used than the Bower lens.
It seems that a majority of independent manufacturer optical lenses come in either zoom or wide angle or extra long focal range fixed length lenses. This lens
meticulousness built in South Korea. and was truly designed for large-aperture shooters.
Although a fine performing lens with lots of contrast and great resolution down around f/5.6-f/11, it's sweet spot is around f/1.4 to 2.8, where it imparts it's highest-peak-resolution focusing point encircled by lesser contrast, resolution out-of-focus zones. Instead of just all around sharpness, for many images it is this blunt reduction in contrast and resolution that successfully draws the viewer's eye towards the subject.
