>>3488456A tip for focusing on the original x100:
Set it to manual focus and use the afl/ael button for back button focus. For critical focus press the rear mode "dial" and it switches to the evf zoomed in to the size of the focus area with focus peaking. Use the focus ring then tap the dial again to return to the ovf.
It takes a bit of getting used to but when the muscle memory kicks in it's fast and reliable. Also the bbf method over rides the stupid "macro" mode setting. I hardly ever use the evf zoom thing but it's there for when you want an eye in focus not a random twig. The distance scale in the viewfinder makes it easy to see at a glance where the focus is set.
All that sounds like a faff but it really isn't in practice once you're used to it. With the x100 you need to be deliberate in your intention. Sure a dslr or mirrorless is faster but can also be pretty dumb.
I think the x100 is a great little camera, the main criticism about af is overstated. imo. The thing was designed to be a manual camera but with all the perks of a modern auto digital.
The only other minor quibbles I have about the original are:
Tiny buttons (I have big thumbs).
"Halos" from bright street lights, nothing major, just down to the rear element of the lens being so close to the sensor.
The d pad is too sensitive, when people ask for a "look" at it they've somehow switched to video mode. Talking of video, pressing the rear command dial engages a 105mm equiv digital zoom with very little loss in quality, neat.
tl;dr The x100 is the photographers point and shoot, there's a learning curve between the pointing and shooting.
