Sigma 150-500mm f/5-6.3 AF APO DG OS

Review Date: Jul 27, 2008 Recommend? yes | Price paid: Not Indicated


I live in Nebraska so I can not get close to a 150-500mm Sigma lens. I had a friend test it against a 100-400mm Canon. I have uploaded a zip file of the full sized files for you to decide. It is 7.5 meg.

All pictures were taken with a canon Rebel XT hand held. They have been resized with Windows XP resized to original size just to compress them some. I have left the EXIF data in the photos for you to look at.

He tried to set the zoom the same on both lens's with the readings on lens, it is not perfect but close.

The files are names y-x.jpg, when the x is odd it is the canon file and when it is even it is the sigma file. When y is 1 it is wide open aperture and when it is 2 it means F8 on both the Canon and Sigma.

The Sigma and the Canon were both brand new at the dealers location. There must have been something wrong with the canon because in the outdoor pictures there is some blue fringing on the right side of the church tower. The canon I own has none of this fringing so I have to assume that the new one has some problems. He did seem to have more "keepers" with the Sigma. This may have been because of problems with the Canon lens.

I have not included any of the photos taken at 500mm with the Sigma but they are very sharp for hand held at 500mm.

Just looking at the photos I find I like the Simga color and saturation in most cases better. I think I will get one to to see how well it works for me.
