| Latest Review Posted | Sigma APO DG OS HSM 150-500mm F5-6.3
I've had mine, which I bought new... for about 8 months. It's sharp and has very good AF. I generally use it for photographing birds of prey in the wild and drag racing cars at the track.
I use it with my K-5, haven't tried it with my Km or K10D yet.
The only issue so far, is the physical size .
As far as the size goes it's not a huge deal.
To me, it's just a function of the amount of glass and after all...it is a 500 mm lens.
I'm an older guy and generally either sit with it...or if I do take it on a nature trek...I'm good for about 45 minutes before I tire from the weight.
I know I could use my monopod or tripod but I do like to use my lenses, hand held.
All in all I love this lens.
It's definitely a keeper. The end product the photographs are very sharp. I like the lens handle attachment...very effective in handling this sizeable piece of equipment.
I'm quite pleased that Sigma has produced this excellent 150-500 with a Pentax mount.
I just wish I had bought it sooner. |
