I was surprised Red didn't update the 50-150... Very interesting focal range.We have the RED ZOOMS as well with the 50 to 150 being the sharpest ZOOM lens we own. Then 18 to 85 is just way to big and heavy for what it does.. Impressive lens optically, but just to big. I'd expect it to be a 25 to 250 at that size..
I'd be surprised if Red came out with some T1.3 lenses with their pricing and quality approach (high quality and very low price)... I reckon it is just too dificult and T1.8 isn't too slow (for most...)
