Sigma 150-500 OS Shots

Hello all Pentaxians

I know sometimes it is difficult to find sample shots of some lenses. A lens in point is the Sigma 150-500 OS.

I thought I would share some test shots I managed to get with the lens, and they have me surprised with the quality - not too bad.

These were shot with my Nikon D300. Very sorry! But, it should give a good example of the lens performance, at least in my case.

All are hand-held, all in bad light (very overcast), all at least 50% crops.

Perhaps others were thinking of using this lens.

ISO720, 500mm, f/8, 1/400s

(here you see strange bokeh - don't jerk the lens while OS is in mode 1 and hasn't stabilized!)
ISO800, 500mm, f/8, 1/250s

ISO800, 250mm, f/8, 1/160s

ISO720, 500mm, f/8, 1/400s

ISO450, 500mm, f/6.3, 1/250s
Overall I find it a pretty good lens for the money! I think I will keep it. Thanks for looking, and I will post EXIF information if anyone is interested.

Edit -- added EXIF. As for corner performance, I haven't tested it at all -- I center all my subjects since this is a birding/wildlife lens. Perhaps I will put up some later

Thanks for posting those cputeq. I was very disappointed with the 170-500 I tried about 5 or 6 years ago. I found it very soft. It looks like the newer optical formula is a great improvement. Now I have LBA again, darn you!

Looks good so far... EXIF please!

It's good to know if any shots are wide open and at what focal lengths. This will give us a better idea of it's performance, although I am guessing most of the crops are from the center? I'd like to check out the edge performance though...
