Decoding Lens Jargon ;)

When I search adorama for sigma 70-300 APO (after visiting Rodneys Flickr photos ), the first 3 used lenses that come up don't say what camera they mount to.

Is it there in the code somewhere??

Digital cameras, all other cameras and everything photographic from Adorama Camera

Sigma 70-300 4/5.6 Apo Mac Af-d W/box
Sigma 70-300 4/5.6 Apo Dg Mac F/nk-afd
Sigma 70-300 4/5.6 Apo Dg Mac F/nk W/bx

I guess the last two are Nikon F-mount lenses. (F/nk)

These are all for Nikon mount: AF-D is a Nikon feature that allows the lens to transmit the focus distance to the camera for flash and metering purposes. "F/nk" is simply Adorama's abbreviation of "For Nikon." Instead of using a search function, simply go to lenses and select the filter to show only Pentax mount, if you want lenses for Pentax camera.

The Sigma abbreviations are explained on the Sigma Web site. "APO" stand for "apochromatic" and indicates that the lens is designed to correct the tendency of telephoto lenses to focus different colors at different points. "DG" indicates that the lens has anti-reflective coatings designed to be compatible with digital SLR sensors.
