i got an autofocus lens to make my life on the job easier, the nikon 35mm f/2D.
I'd say like, 10-20% of the time the autofocus noticeably failed, but for the rest of the time it's really made my workflow easier. I can actually shoot at wide apertures and have people in focus! No more guessing my focus in the darkness and no more tight apertures resulting in high ISOs!

In hindsight, I realized I should be shooting with autofocus on shutter disabled and just use the AF button and take over the focus with manual at the soonest sign that the AF was crapping out. This is the theme of my rave assignments, it's 5 hours of grinding photos, I learn a lot fast both during and after the shoot.

Luckily, a few of the times AF failed me turned out to be fun shots, like this one.

Not settled yet on a consistent editing theme for em all so this one is edited pretty neutrally.
