This Sigma 150-500mm f/5-6.3 DG OS HSM APO Lens is for digital SLR cameras with a Pentax K lens mount. It is an ultra telephoto zoom lens ideal for nature, wildlife, or sports photography. This zoom range translates into an equivalent range of 225-750mm when used with digital SLR cameras with an APS size chip. The lens is also compatible with full frame cameras.
The OS (Optical Stabilizer) system minimizes image blur caused by camera shake, and offers the equivalent of shooting at a shutter speed 3-4 stops faster. This allows handheld telephoto zoom shooting even in poorly lit conditions.
The use of the OS (Optical Stabilizer) system, HSM (Hyper Sonic Motor), APO apochromatic design, three elements of SLD (Special Low Dispersion) glass, and multicoated optics all enable this lens to provide a high level of performance throughout its entire zoom range, as well as versatility. A rear focus system insures quick, convenient manual focus and a non-rotating front barrel.
The improved DG lens design corrects for various aberrations. This lens is specially coated to get the best color balance, while cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration, which is a serious problem for digital SLR cameras.
By adding the optional Sigma APO teleconverter, you can use this lens as a 210-700mm f/7-9 manual focus ultra-telephoto zoom lens with a 1.4X EX teleconverter, or as a 300-1000mm f/10-13 manual focus ultra-telephoto zoom lens with a 2X teleconverter.
Note! If the camera body does not support the HSM motor, auto focus will not work.

Comments about Sigma 150-500mm f/5-6.3 DG OS HSM APO Autofocus Lens:
I'm a "hobby" photographer who has been waiting patiently to afford a long distant lens to take pictures of birds in my area and now I have found it.
I've only used it on 2 photo trips but am more than happy with my results.

Comments about Sigma 150-500mm f/5-6.3 DG OS HSM APO Autofocus Lens:
I chiefly use this lens for bird photography. I have used this lens and got fairly sharp pictures handheld. The OS system works quite well for me on my pentax K-x. It is a fairly sizable lens, many people might not be able to handhold it successfully. I am very happy with it, my only reservation is that mount has a little play in it, it is not perfectly tight.
