The Sigma 50-500mm f4.5-6.3 DG OS HSM lens is an upgrade to Sigma's popular 50-500mm ultra-telephoto zoom, and now includes an Optical Stabilizer which offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible - a particularly useful addition on a lens of this size. The Sigma 50-500mm OS lens incorporates HSM (Hyper Sonic Motor), to ensure quick and quiet auto-focus, as well as full-time manual focus capability. Four SLD (Special Low Dispersion) glass elements provide excellent correction of colour aberration, while the Super Multi-Layer Coating reduces flare and ghost and ensures high image quality throughout the entire zoom range. The addition of the optional 1.4x EX DG or 2x EX DG APO Tele Converters produce a 70-700mm F6.3-8 or a 100-1000mm F9-12.6 MF zoom lens respectively. The filter size of this lens is 95mm, but the lens is supplied with a step down ring enabling digital cameras with an APS-C size image sensor to use an 86mm filter.

Comments about Sigma 50-500mm f4.5-6.3 DG OS HSM - Pentax Fit:

I bought this lens as an upgrade to a non-OS 150-500mm (also a good lens) and have not been disappointed.
I use it mainly for wildlife on my regular walks, either on a sling at my side or in a large Lowepro holster case. Zoom range is excellent and focus is fast and silent. The Lens OS is so good I now use it in preference to the in-camera SR system, although it does drain batteries a lot quicker so make sure you have fully charged spares if you are going to be taking a lot of photos.
Image quality is also great, a slight drop-off at 500mm but not too much. It's a heavy lens to lug around for long periods but not as much of course as a 500mm prime lens would be. A bit of practice is perhaps needed for handheld use to find the best / steadiest hold, but once mastered I stopped lugging a tripod about, again though the OS helps a lot.

Bottom Line Yes, I would recommend this to a friend
