I was able to attend the event last Saturday. Although there were many products to explore, my curiosity on the new Sigma lenses allowed me to cue in to get a feel for the Sigma 135mm f1.8 prime lens. Unfortunately, it won't be available until this March, so like most cameras, we were not able to use our SD card or CF card to get a test on lens sharpness. Without knowing the specs, I am assuming that it is much lighter than my Sigma 85mm f1.4, but that is just my estimate since most f1.8 lenses are much lighter. Focusing was a little bit sluggish but maybe that's because of the low light condition and that Cannon camera (kidding).
Just sharing since I haven't posted in decades.
Sigma 24-70mm f2.8 - it looks similar to the Nikon 24-120mm f2.8
