I got a Fujifilm X-Pro1 camera several years ago and I immediately fell in love with it. Its rangefinder styling and physical controls reminded me of the film cameras that I grew up with. More importantly, the X-Pro1 was fun to shoot: I felt as if I was using a finely-crafted tool instead of an impersonal electronic device. I believed the X-Pro1 actually helped me take better pictures.
The X-Pro1 is far from perfect. I am most frustrated with its lack of speed: it's slow to focus and takes forever to write RAW files to the SD card. It's a bit too small for my hands - I keep hitting the Q button by mistake. Its battery life is abysmal.
And yet, those images, when everything goes well ...
I photographed a couple of models in the streets of Georgetown, Washington DC, with the X-Pro1 and the by-now ancient 35 mm f/1.4 XF R lens. I shot JPG only, using the Pro-Neg S color profile, with sharpness and highlights turned down one or two notches. I used this lens mostly around f/2-2.8; the resulting high shutter speed meant that I could not use any flash, only available light. As expected, the images were lovely.
I also mounted an old Helios 44-3 58 mm f/2 and took some portraits. Using the X-Pro1's EVF, I had little trouble focusing. I was less happy with the images, however. Sharpness on-center was acceptable, but move a bit off-center and highlights get smeared. Not a great effect for what I wanted to do that day.
Two weeks later I had another test shoot and the historic Chapman Mill in Manassas, Virginia, and for that session I rented a Fujifilm X-T2 and the 18-55 mm f/2.8-4 R LM OIS lens. First, the X-T2 is so much faster. Focusing seems instantaneous, the controls are much better laid out, and battery life is at least 50% better than the X-Pro1. I loved using the EVF; it's almost better than an optical viewfinder, especially for my aging eyes. I hear the EVF has some very useful tools when focusing manually, which would come in handy with adapted lenses.
The 18-55 mm lens redeemed itself very well. Far from being an ordinary "kit" lens, it was sharp, focused accurately, and rendered colors beautifully. I even prefer it to the Fujifilm 16-55 mm f/2.8 lens; the 18-55 gives up the wide f/2.8 aperture and 2 mm of focal length, but its image stabilization is very effective. Ultimately, I had an easier time achieving sharp photos with the 18-55 versus the 16-55.
Bottom line: two thumbs up for the X-T2, and even the 18-55 mm zoom. It's more than enough to make me give up my Nikon DSLR setup!
