You know, I've always been a big fan of Micro four thirds, but even more so after last night. We have two dogs, one of them being our now 5 month old Cocker Spaniel pup - Daisy. Last night I dusted off my Fuji X-H1 with two of Fuji's best lenses - the 16-55 F2.8 and the 50-140 F2.8. I was actually very disappointed. I wasn't using flash (deliberately) and so it was via LED kitchen lights (so at night, still pretty dim). The dogs were on their bed so not really moving round much, but both are black (Daisy has white markings on her nose and throat, but Charlie is pure black).
With both lenses, the Fuji hunted back and forth, when it did achieve focus, despite saying it was in focus, a few times on image review a number of the images were clearly out of focus. Also I was shooting at ISO6400 with shutter speeds as low at 1/20 -1/80 sec, and the noise on the image didn't look very nice at all.
I then went upstairs and got my EM1.2 and the 40-150 F2.8 and low and behold, under the same lighting, the Olympus just snapped into focus each time (and it was clear on image review they were actually in focus). Also, despite shooting under the same conditions (ISO5000-6400) the images actually looked better on the back of the LCD, which was confirmed when I got them into Photoshop. Whilst certainly no where near full frame clean, a bit of PP and they cleaned up quite nicely. Don't get me wrong the Fuji system has other strengths, but with the X-H1 in particular, low light focusing isn't one of them. God only knows how good the new EM1X must be under the same conditions ?
Just a snap really but you get the idea.
