Sigma 500mm f/4.5 EX DG IF HSM APO Lens

The 500 F4.5 APO EX DG HSM lens is fully compatible with all Nikon Digital SLR cameras including the D40, D40X, D60, D3000, D3100 and D5000.

This DG lens is designed to work on 35mm SLR film cameras and digital SLR cameras with 'full frame sensors. it can also be used on the cropped sensor cameras as the image circle it casts on the sensor is larger than needed.

The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.

This ultra-telephoto lens has a fast maximum aperture, and also features a new super multi-layer coating, which optimizes the characteristics of digital SLR cameras. Two ELD glass elements in the front lens elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast.

The overall length of the lens does not change during focusing, ensuring convenient handling and ease of use.

The AF drive for Sigma SA, Canon and Nikon SLR. cameras features Sigma's ultra-quiet and high-speed Hyper Sonic Motor (HSM). It also features a drop-in 46mm filter holder in the rear part of the lens barrel, which can be rotated to facilitate the use of filters, including a polarizing filter.

HSM means this lens will autofocus on Nikon D40/D40x, Nikon D60, Nikon D3000, Nikon D3100 and the Nikon D5000 DX Cameras

By adding an APO teleconverter (optional extra), you can use this lens as a 700mmm f/6.3 MF ultra-telephoto lens with a 1.4X EX teleconverter, or as a 1000mm f/9 MF ultra-telephoto lens with a 2X teleconverter.

Super Telephoto Lens
High Power telephoto lenses from 400 mm to 800 mm (APS-C 300 mm 500 mm) and longer are very expensive, even for the slower versions, but they provide the ultimate in telephoto photography. Deep pockets are needed for most lenses in this range, particularly the faster versions, as one lens can cost more than the average person may spend on photography in their life. A super-telephoto lens can reveal far-off objects barely visible to the human eye.
A professional-quality 400 mm ƒ/2.8 lens is the ultimate dream lens of many sports and wildlife photographers, which they may save for years to acquire. A 600 mm ƒ/4 lens is even more striking, but the 16-times magnification of an 800 mm ƒ/5.6 lens can also be used for astrophotography with clear, vivid results.

Professional photographers are the primary consumers of such magnificent lenses. A majority of the images we see in publications are shot with these lenses.

Excellent lens at 2/3rds the price

By Dennie from Rapid City South Dakota on 1/16/2008

This is an excellent lens. Extremely sharp focus, fairly lightweight for an F4.5. Will not autofocus with the sigma 1.4 EX teleconverter but no big problem. About 2/3 the price of a Nikor lens. Rotating filter drawer works well with a polarizing filter. I have used this lens to photograph big game in the west and it has been a real workhorse for the $$$$$
