Did my keeper rate improve? Yes. After shooting 2000+ frames of running, jumping, playing dogs and flying birds, I am happy to say that my keeper rate increased significantly. I am now averaging over 90%.
So the Fuji XH1 must have a superior focusing system, right? The focusing system on the XH1 is truly excellent. However, technically, the 7DMK2 may actually focus faster and more accurately. And I am certain that any top-of-the-line Canon, Nikon or Sony camera designed for sports photography has an even better focusing system.
The main reason I am getting more keepers with the XH1 is the fact that it has a mirrorless, electronic viewfinder. You see, when using a DSLR, I sometimes lose track of rapidly moving subjects due to the disorienting phenomena known as "viewfinder blackout" caused by the camera's mirror slapping up and down 8 or more times per second. And even when I do manage to stick to the subject, I sometimes feel a certain amount of mirror 'slap' which can contribute to losing track of the subject as I twist and turn to keep up.
With the XH1's electronic viewfinder, black-out is far less noticeable. I can actually keep my eye — and the focus points in the viewfinder — glued to a dog no matter how fast it runs. In addition, the remarkably quiet shutter mechanism on the XH1 is silky smooth, producing virtually no vibration or 'slap'.
Check out this video of a side by side comparison of the blackout seen in an electronic viewfinder and in a DSLR viewfinder, both shooting at 8 frames per second. Note how the blackout on the DSLR is longer and how the image is briefly distorted by the mirror moving out of the way. It is especially noticeable in the slow motion portion of the video and may be the reason I find viewfinder blackout in a DSLR so disorienting.
Bottom line: my new camera has a great focusing system, but it's the mirrorless viewfinder that is key to a higher keeper rate since it helps my own built-in focusing system — good old fashioned hand-eye coordination — do a better job at tracking moving objects.
Are there other things about the camera that impressed you? Yes! Not only is the electronic view finder fantastic for taking photos, but being able to review images and zoom in on them in bright sunlight is amazing! I also love the ability to map just about any camera function to just about any button or dial on the camera. A bit of arthritis in my fingers can present certain challenges with some of my other cameras, but with the Fuji, I am able to customize the interface to suit my own requirements. Perhaps best of all are the amazing jpegs I get straight out of the camera. The colours are wonderful and working with jpegs should mean less time at the computer tweaking raw files in Lightroom and Photoshop.
Any downsides? Yes. The XH1 had a voracious appetite for batteries, and that means always carrying spares. Fortunately the batteries are light and relatively inexpensive. The camera can also get fairly warm when shooting in burst mode. It is not uncomfortable, but when I photographed the Wild Dogs event, in direct sunlight, with a black camera, a black lens and temperatures in the mid 30s, it was certainly noticeable.
What about video? For now, I want to focus on still images with my XH1 and adjust my workflow and my post-processing routines. But I will definitely dig into its video capabilities in the near future. Stay tuned!
So are you switching systems? Not really. I got into the Fujifilm system a few years ago when I picked up an X100 and an XPro1. The addition of an XH1 just means that I can now sell off my biggest and heaviest pieces of Canon gear since my back, shoulders and neck have been telling me for years to lighten the load I typically carry into the field. If/when Canon introduces a pro-level mirrorless camera, I will certainly give it a close look. But for now, when I am out there chasing dogs, I will probably have a Fujifilm camera in hand.
UPDATE: I've now added a Fujifilm XT3 to my kit and it is even better in terms of auto focus speed and tracking. It is now my main body for action shots of dogs. Of course I still use my XH1, but more for video or for when I need in-body-stabilization in lower light. And yes, my Xpro 1 and X100 are still going strong. They are perfect, everyday walk-around cameras for when I am not in the field trying to keep up with speedy dogs. So the answer to the above question "are you switching systems?" is now YES. I've sold off all my canon gear and shoot exclusively with fujifilm cameras and lenses now.
