Tried yesterday getting our 18 weeks old Cocker Spaniel pup Daisy to run towards me whist I took some shots. She's lighting quick and I thought I'd use it as a test of all 3 of my cameras. All cameras in Auto ISO, Shutter priority (at 1/1000 sec).
First the Olympus OMD EM1 MK II (gripped with 2 batteries). I tried this with two lenses, my 12-40 F2.8 and 40-150 F2.8 pro. Drive mode set to 10 fps. About a 35% keeper rate. Initial acquisition was a little slow then picked up. It's the only area really where my Olympus kit sort of disappoints. AF-C is average, but everything else about the camera and lenses (for me), is superb. Happy to take any advise from M4/3 shooters if I'm doing anything wrong (or have the wrong settings) i.e. C-AF lock settings ?
Second my Fuji X-H1 with 16-55 F2.8. To be honest, I thought this was smoke the Olympus, but in my tests, it was only slightly better, maybe 40% tack sharp. Drive mode set at 10 fps. Now it could be because I'm fairly new to Fuji and haven't dialled in the proper settings yet (boost mode on, gripped X-H1 with 3 batteries, Zone AF, AF-C). I tried most of the custom settings and got the best results with Set 3 (accelerating and decelerating subjects), and set 5 (Erratically moving and accelerate subjects / decelerate subjects). Work in progress I guess. For landscapes and most other types of photography, it's a superb camera with a set of fantastic quality lenses. I know the X-T3 has a different AF module and better AF than the X-H1 (and X-T2), but in the real world, does it really smoke these two and is as good or better than the D500 ?
**edit** one thing I just remembered which might account for the X-H1 not performing as well as I thought, was that I had image stabilisation set to on. I think for these sort of shots and certainly at the shutter speeds used (1/1000), it should have been off - Think I need to perform this test again with IBIS off ?
Finally I tried her with Nikon D500 (gripped with 2 batteries) with the "kit" Nikon 16-80 2.8-4 lens. AF-C, Group AF, continuous High (at 10fps). Hit rate suddenly went up to about 85-90% tack sharp. I couldn't believe how quickly the D500 locked on then just stayed locked on like a limpet. It's the first time I've ever really put all 3 cameras up against one another. Another thing I found was that even though the X-H1 and D500 are both APS-C sensors, as it was quite a dull overcast day, my ISO's in some instances went over ISO 5000 (though not for the 3 images below), and the D500 images were by a margin the cleanest of the two. Surprisingly, the EM1 MK II, wasn't far behind at all the X-H1 in the High ISO stakes? I should also mention, one of the other things I really like about the D500's AF system, is that you don't have to mess around with lots of menus settings to "tune" the AF system. I simply set into AF-C mode, then turned the sub-command dial until it said Group AF, and shot away. That was it ?
Anyway a few images of Daisy from the shoot. She really was moving a lot quicker than the images might suggest. Love her expression on No 2. The difference in colour is that images 2 and 3 were done with the cameras auto WB and image 1 set to WB daylight (so is warmer). I could have equalised the colours in my image processing program, but the images are pretty much as it (from raw) with just minor tweaks and cropped to suit.
