This past week I had an equipment malfunction that put me out of commission. The electrical contacts on my new Fujinon XF100-400 f/4.5-5.6 lens were not making good contact with my Fuji X-Pro2 body. Fortunately, I was still under the 30-day return window at B&H, so I returned the lens for a replacement.
I'd also been thinking about upgrading my camera body from the X-Pro2 to the newer X-T2 (the T2 is comparable to the Pro2 in many ways, but it has slightly better continuous-tracking autofocus, a larger and brighter electronic viewfinder, and a larger grip, which makes handing large lenses a little easier). Since the lens was out of commission anyway, I took advantage of the down time to sell my X-Pro2 and order a new X-T2. I made arrangements with B&H to have it arrive the same day as the lens (which it did, thanks B&H), and I'm now fully back up to speed.
I don't know if it's my imagination, but I feel like I'm getting sharper results with this new body and lens. These two camera bodies use the same sensor, so if there is a difference, it could be that this particular lens in sharper than the last one (there can be quite a variance in sharpness from one copy of a lens to another). In any case, I'm glad to have everything working properly; I'd almost forgotten how astoundingly good the images look coming out of these little cameras and lenses.
