Wanting to stay with a Canon, I looked at their mirrorless range, thinking I could have the best of both worlds: interchangeable lenses but something smaller than my often-cumbersome 5DII. But reviews weren't always great, and none of their products stood out for me. I looked at Olympus, Sony, and Leica (wishful thinking), before coming across the Fuji X range. My ideal choice would have been the X-T2, but finances and reviews led me to the X-T20. And I'm really happy with it.
The thing I really love about this camera is the retro look and feel of it. Unlike my 5DII, where I have to take the camera away from my face each time I want to adjust the settings as I shoot, the controls on the X-T20 are placed (intuitively) at my fingertips, so I can easily adjust the key settings without over-thinking what I'm doing. It reminds me very much of my old film cameras. And I'm loving it!
