Just got her rolling, will give it some time. Off the batt, and top of my head: you better like the DT, it's threaded and is your top cap for filling. I think I'll be OK with it, but probably gonna wish it was a tad longer. Came with ultem and black. Interesting AF options: comes with two 510 pins, one for bottom air only, the other can be used for bottom/side at the same time, or side only. Kinda cool. I am trying bottom only first. Not exactly sure how af works, as you can see no visable af holes. The bottom is a AF ring, and it does move and adjust AF, just no holes there I love it for looks, just not getting it. Will have to look into.
