The Tamron is a focal length I'll use more often, and the size/weight/VC make it more user friendly, but the Sigma seems like a winner as well. Both are plenty sharp, have low longitudinal CA, focus quickly and accurately, and render to my liking.

Ya, I just realized the Tammy was the 85, see above edit... :rolleyes:

Thanks, William, Klaus!

Keith: AF speed is very good, and there is a focus limiter switch which helps. No complaints in that regard.

Here they are side by side. The Sigma is a big hunk of glass!

Couple soccer shots today. I have no experience shooting sports at all, but the lens seemed to do its part just fine.

reminds me of an FF version of the Olympus 75mm 1.8! If rumors are true, the Sigma 135mm 1.8 Art shares a little optical DNA with that lens as well!
True, it's been mentioned on the MU-43 often enough that that Sigma was very much involved in the making/ construction of the Oly 75.

So, @Amin Sabet , how do the 2 lenses compare?

They are both very sharp, render neutral bokeh, and focus quickly. The rendering is different - the Sigma has slightly swirly bokeh whereas the Olympus stays round with a bit of cat's eye in the corners. Also, the out of focus transition of the Sigma is very abrupt. It can look like a subject has been cut out and pasted onto a background.

Thanks, not the time to bin the 75 just yet then (I don't think I ever will).
