An Economical Way to Achieve Some Ultra-Telephoto Photography


Bower 650-1300MM F8.0 Phd Digital LensThis extreme 650-1300mm f/8-16 Manual Focus Lens from Bower is an economical way to achieve some ultra-telephoto photography, all the way up to 1300mm. This is a T-mount lens, which means that aperture is not communicated to or controlled by the camera body, and as such must be used only in aperture-priority autoexposure mode (if your camera has it) or in the manual exposure mode. There are T-mounts available for every modern DSLR system as well as for most older film cameras and even C-mount cameras.

It will work on both "full frame" digital cameras as well as the smaller-format APS-C (15 x 22mm) cameras, but has only one effective aperture at any focal length, which varies from f/8.0 at 650mm to f/16.0 at 1300mm. That's not much of a hindrance, however, as you'd likely use this lens at its relatively small maximum aperture in any case.

This lens requires bright light and a high ISO setting on the camera to get a fast shutter speed (or fast film in a film camera), and needs a sturdy tripod or monopod, but can deliver very sharp results if used properly.

WOW great pictures

By Suz from Aurora, CO on 3/22/2010

I am getting ready to go to Alaska on a Cruise and wanted something to take pictures from the Ship. I took the Bower up to the National Park in our area and shot some really great pictures of the Mountain peaks from the Park. It was just like I was there at the top of the mountain. The lens case is not long enough to keep the T mount for the Nikon attached to it with a cover on it for protection.

Great long range lens

I purchased this mainly for wildlife shots but was amazed when I used it to shoot the full moon three nights after I received it in the mail. The craters and ridges of the moon were awesome. This is definitely not a walk around lens but when you want to get close it can do it, a tripod is a must, not a cheap one, a good sturdy one.
