Not going all primes, but enjoy and use them often. I needed something a little longer, but still fast, for indoor sports and activities... I usually use my 85 1.8 for portraits, but can't wait to see what this does there either.
Couple of quick snaps after it arrived. Both taken around 7:30, so already pretty dark. ISO 3200, f2, 1/100 (for some BG light and flash for fill). Lovely background of my garage!
