I use Ak2000 for my Sony A6000 with F4 18-105 lens and it works great. I went on vacation at sea, there were no problems. Although I would like to have a newer camera to take advantage of the wireless connection. Battery life is great, I didn't even charge it for a couple of days but it's not like I left it on for hours. The touch screen is also really useful. I like that the motor doesn't get in the way of the screen. The tripod that comes with the kit is also very useful as it makes the handle longer. I'd recommend putting tape on the handle, it just doesn't grip it for me lol. Not Ronin, but half price and as good as it's worth.
