I had a Bigma and wanted to see if a switch to the Bigmos was a good choice or not.
I decided to do my own tests as when I got the Bigmos there were no tests between these two. I don't know if there are any extensive tests on them yet either.
My test is only of the quality of the images in relation to sharpness using AF.
I also tested the OS feature vs none on the Bigma. There is text on the site to explain the photos and tests.
I had heard before buying my Bigmos, that the AF was very slow. The tests I've done do not show that, it's at least as fast as the Bigma.
I have not done any post processing to any of my photos. They are directly converted from RAW (NEF) to JPG. They are in ProPhoto RGB color space so a color managed browser is preferred, or you can download them and use color managed viewer.
I'm not giving any personal thoughts on the results of the tests, other than those about the AF and OS.
It's up to each and everyone to do their own conclusions.
I hope my work helps someone.
Here is the test:

All photos are available for download at original size at the site.
Will remove my test as there is no interest in it.
Perhaps the reason why there seems to be no interest is that when you follow that link you have to SIGNUP for Flickr. I sure don't want to have to join something just to look at pictures. I think you should consider using a different method to post your pictures. I did want to look at them till I encountered that.
