Sigma 120-300mm Lens


I am thinking again about what to do to get in closer to my wildlife subjects.

Since I already have the Sigma 2x Teleconverter I went to their webpage to see if they had a nice zoom that would continue to operate w/AF function and have a larger aperture.

I'm also not ready to make a huge investment in a $4, $5 or $6000 dollar lens. This one comes in at $2199 excluding that (un)necessary filter.

I think I found a good lens and would like your opinion.

Thanking you now for your time & efforts on my behalf.

****************************

The Sigma 120-300mm f/2.8 EX APO DG IF HSM telephoto zoom lens provides a large constant f/2.8 maximum aperture at all focal lengths. In essence, it transforms a large-aperture 300mm f/2.8 lens into a zoom lens that allows to determine the picture composition without having to change the vantage point.


The use of Apochromatic design and SLD glass elements, an AF drive is equipped with the silent, responsive and high speed Hyper Sonic Motor, Internal Focusing, all ensure optimal quality and usability. The DG design makes it fully optimized for use with digital SLR cameras.

Note: HSM lenses, while able to manually focus with all Nikon F-mount cameras, will autofocus ONLY with the following cameras- F6, F5, F4s, F100, N90s, N90, N80, N75, N70, N65, D1 & D2-series, D50, D70, D100, D200, Pronea 6i, and Pronea S (or newer camera models). With other models, HSM or AF-S lenses must be focused manually. This is the same limitation as Nikon's own AF-S lenses.


Key Features

• DG Lens Design
The improved DG lens design corrects for various aberrations. This lens is specially coated to get the best color balance whilst cutting down on ghosting caused by reflections from the digital image sensor.

• SLD Glass and Aspherical Lenses
The use of Apochromatic design and 4 SLD (Special Low Dispersion) glass elements give full correction of chromatic aberration and provide a high level of optical performance.

• Internal Focusing and Internal Zooming
This lens incorporates an internal focusing system, which eliminates front lens rotation, allowing the use of a Perfect Hood and easy to use circular polarizing filter. Handholding is easy since focusing and zooming do not change its overall length.

• Dedicated APO Tele Converters (optional)
Compatible with the dedicated Sigma 1.4x EX and 2x EX Apo Tele Converters to convert it into an ultra tele-zoom lens. This lens can be converted to a 168-420mm f/4 AF tele-zoom lens with the 1.4x tele-converter, or as a 240-600mm f/5.6 AF ultra-telephoto zoom lens with the 2x tele-converter.

• Tripod Mount
The rotating tripod mount can be conveniently detached if required

The other question is whether I should keep the other Sigma 50-500mm lens or sell it. Mom says keep it.
