Default Sigma 150-500 Test for Wingman

I picked up a used Sigma 150-500 OS last week for the extra reach over my Canon 100-400L. Decided to compare them using a tripod and a cable shutter release. Here is the full image taken with a Canon 5D MkII

Here are the 2 lenses at 150mm and at 400mm on the Canon 5D MkII. Note that the smudges on the clock face (upper left) are actually on the clock itself.

The Canon 100-400 clearly has more light-gathering capability with a max f5.6 vs. 6.3 for the Sigma.

I then used my 7D body to shoot at 500mm on the Sigma. Here is the full image. Note that the 7D is a 1.6 crop, so the shot is an 800mm equivalent.

And, in keeping with the gallery theme, here is a trio on bikes taken with the Sigma 150-500 at 370mm on a 7D (592mm equivalent).

Walter, based on images 3 & 4, I'd say sharpness looks pretty good especially at full zoom. I find that the lens is not as forgiving as my Nikkor 70-200 f2.8 for my aviation photography, perhaps becuase of the slower focusing as well as the lower speed of the lens opening which forces the camera to use slower shutter speeds.

Hope you have fun with it!

Walter,

I have thought of getting a Bigma with a Pentax mount. I was never too sure how good the Sigma would be, compared to a high standard lens such as a Canon L or a Pentax DA 300.

Going by your pictures though, the Sigma seems to be a very good performer.

Other than the better light gathering ability of your Canon lens (faster F stop) how else would you assess the quality of your recently purchased Sigma ?

Hey, Les.
It's too early to give you an informed view as I've only had the lens a few days, and limited use due to the holidays. It does seem, though, that I've got to learn how best to use it, especially for action shots. The OS (image stabilization) seems to work quite well with hand-held shots, perhaps better even that the 100-400L. But I'm not getting the percentage of keepers I would want. Rather than blame the lens -- which my simple tests (above) seem to show pretty good on-tripod performance -- I've got to work on my technique. Plus, in the "field" I've been using the 7D which I also picked up (used) a few days ago. I'm sure the combination of new (to me) lens and body will have a learning curve.

Walter

PS, I had a Bigma about 6 years ago and wasn't happy with it. Of course, it doesn't have OS and with its weight I found that I had relatively few keepers. That led me to the 100-400L IS.
