Product description from Sigma
At launch 2005 Sigma wrote this regarding Sigma EX 50-500mm F4-6.3 DG HSM :
"Sigma’s APO 50-500mm F4-6.3 EX DG is an advanced optical design of this 10x power high-performance zoom lens that covers the standard-to-super-telephoto range. For many photographers, having an ‘all-in-one” lens is an absolute dream. Especially for nature photographers, the idea of a lens suitable for landscape photography at the short end of the zoom range, while still having enough reach for wildlife is a great option. Add to that, the ability to close focus on small objects in the field such as flowers and it’s the perfect backpackers’ lens. Four SLD (Special Low Dispersion) glass elements provide optimum color correction & sharpness throughout the entire zoom range and super Multi-Layer lens coating reduces flare and ghosting and assures high image quality throughout the entire zoom range. With no need to change lenses, there is less chance of dirt or moisture entering the camera and fouling the imaging sensor.
Designed for use with full frame digital SLR cameras. May also be used with smaller APS-c size sensors with a corresponding effective increase in focal length to about 75 to 750mm with most cameras
HSM (Hyper-Sonic Motor) ensures a quiet & high-speed auto focus
Minimum focusing distance of 10 feet with a magnification ratio of 1-5.2
Rear Focus System eliminates front lens rotation
This all-purpose lens weighs 4 pounds with an overall length of less than 9 inches"
Compatibility, autofocus and focal length
The lens is available for both Canon and Nikon cameras, but there are two different versions of this lens (one for each brand and mount) so it is important that you ask for and choose the right version when bying the lens.
This lens is constructed to fit all models of Canon and Nikon cameras, regardless of camera model or type of sensor.
The ability to use autofocus is available for all cameras.
The lens has a focal length of 50-500 mm. Depending on which camera the lens is used, the experienced and perceived focal length will be different. Please visit the list of compatible cameras below, it will provide the equivalent focal length you get on each camera.
A positive thing is that this lens has a versitale zoom range, where the difference between 'maximum zoomed out' to 'maximum zoomed in' increases the lens versatility since you as a photographer easily can compose your picture without moving yourself physically.

Lens brightness and image stabilizer
The lens brightness and aperture value is f/4-6,3.
This lens is not considered to have a good aperture value and brightness. It is something to consider before you purchase the lens. To compensate for this you might, while photographing in less favorable light conditions, be forced to either use higher ISO settings (which generates more noise in the image), slower shutter speeds (which may give some motion blur) or flash lightning. Read more at the link below what lens brightness means to you as a photographer.
One thing to consider is that the lens has a variable brightness, which means that depending on how much you are zooming the lens will have a different maximum aperture value. At 50 mm the lens brightness is f/4 and at 500 mm the brightness is f/6,3. Through the link below you can read more about what this could mean for you as a photographer.
The lens lacks image stabilization, which otherwise os good for avoiding the blur that can occur when using slow shutter speeds.

Filter and Lens Hood
The lens has a traditional filter thread on the front and its measuring 86 mm which also the filter you will use must have. If you use for example an UV filter can be a cheap insurance against scratches and dust.
Together with the lens there is a lens hood included but we have unfortunately no further information on model etc so feel free to contact us if you know more.
Tripod Mount
This lens is equipped with a tripod mount, which makes use of a tripod easier and more stable.
