Questions have come up during my tests and in talks with other photographers.
What increment should be used? The Canon R5 comes set at increment 3. That’s a good starting point and what I used on my first tests.
I changed to increment 7 for the purple passionflower blooms. I like 7 now.
How many photos are needed for a good photo stack? Obviously, that depends on how deep the subject is. I used 10 on the long-tailed skipper and 10 on the red passionflower bloom. The skipper is much smaller than the flower.
In my tests, 10 photos seems to be a sweet spot. The Canon R5 takes less than a second to fire off the series of images. Push the shutter button one time and the camera does the rest.
I used Photoshop’s focus stacking and tried 3, 5, or 1o images. The stacks with 10 images were smoother and better aligned.
Where should the focus point be at the start of the stack? Focus should be on the closest point to the camera. That’s a lesson learned.
On the long-tailed skipper, I focused on the wing closest to the camera. In earlier tests, I focused on the head and the wing closest to the camera wasn’t sharp.
On the red passionflower, I focused on the flower in one photo. In the second photo, I focused on the buds in front of the bloom. Notice the difference?
All photos were taken with the Canon R5, 100-500mm lens, 1.4x extender, f/11, ISO 400.
Questions? What’s been your experience with the R5’s focus bracketing? Does your mirrorless camera have focus bracketing or stacking? Experience?
I finally got a chance to sit on the beach and play with the Canon R5’s autofocus. At heart, I’m a bird photographer. How would this new camera function on fast moving birds? My DSLR is a Canon 1Dx. I hoped the new mirrorless had autofocus equal to or better than that camera.
Can the autofocus on the Canon R5 separate one bird flying from a flock of birds? I took 14 frames of this black skimmer flying into a group of birds roosting on the beach. Below you can see the first seven frames plus bloopers.
The R5 fires 14 frames a second so the above is only 1/2-second of shooting. What happens next?
Settings on the above: Aperture Priority, ISO 640, Shutter speed 2000, f/10, spot meter, Servo, Large Zone AF Horizontal, AF-2, 100-500mm lens at 500mm with 1.4x teleconverter.
Conclusion — the Canon R5’s autofocus system is equal to – if not better – than the Canon D1x’s system.
What’s been your experience with the R5? I’d love to hear your thoughts.
I headed out with the Canon R5 in hand attached to the new 100-500mm lens and 1.4x extender. This would be my first time to try action photography with the R5 and first outing for the 100-500mm.
I decided to work with hummingbirds. These little gems are a challenge for any action photographer. Right now, we’re in the middle of hummingbird migration on the Upper Texas Coast so I knew there would be plenty of subject.
Kleb Woods Nature Park in Tomball, Texas, has 15+ hummingbird feeders this time of year and usually attracts lots of hummers. I wasn’t disappointed. From 12:30 to 2:30 pm on a warm Saturday afternoon I shot 1326 photos. After basic editing in Adobe, I had 494 keepers. I was super happy with 110 of my photos. Not bad for two hours of work.
Overall, I was very pleased with the R5 and 100-500mm lens.
In one feeding series, I shot 49 images as a ruby-throated hummingbird flew in and out to the feeder. The ruby-throat flew in, took a drink from the feeder, hovered, took another drink, hovered, took a drink, hovered , drank, hovered, drank, hovered, drank. Six sips of nectar with hovering in-between. I kept 39 photos out of that session. 39 out of 49, or 80%, is not a bad success rate with hummingbirds.
In another series, I took 90 photos as a hummer visited the feeder. That group had 23 shots that were worth keeping because they were sharp and in focus. That 25.5% or a quarter keepers.
Within about an hour, I figured out settings with the new camera and got into the groove of photographing hummingbirds in flight. I’ve photographed hummingbirds like this hundreds of times, but this was the first time I let the camera take the lead.
I set the R5’s auto-focus and then I let it do the work.
I found the greatest success with (1) Servo, (2) Subject to Detect: Animals, (3) Servo AF 2, (4) Large Zone Horizontal AF. Yes, this last one is a big change for me. (I’ve always been a single-point autofocus person.)
An hour into the shoot, I fired off 22 shots of a male ruby-throated hummingbird during one feeding session. That series lasted less than a minute and I threw away two. Keeper ratio 22 out of 24.
An auto-focus system should be able to do a pretty good job when there are only two objects in a frame: feeder and hummingbird. What happens when the hummingbird is at a bush with foliage in every direction?
I stepped over to a hamelia bush to continue testing the Canon R5’s autofocus capabilities. When a hummingbird flew down to a flower, I took 36 shots and kept 6. That’s only 16% keepers but several of those were tossed in the trash because the bird had its back to the camera.
When a hummer came in to feed on the hamelia and there was a clean background, my keeper rate was 100%. The Canon R5 kept the bird in focus the entire time it visited the flower — and I kept the camera on the bird.
What happened when there were several items in the frame?
In one series of photos, I had a feeder with three hummers hovering around the feeder. The Canon R5 kept focus on the hummer in the center of the frame. It’s autofocus system didn’t get distracted by the hummer on the right edge of the frame or the one on the left.
Through the viewfinder of the R5, we see tiny blue dots flashing on the subject to let us know that the camera’s found the subject and is in focus. These dots are similar to the red dots we see on the Canon 5D Mark IV or the D1X. Nice confirmations to let us know the camera is doing its job.
Thanks to the nice folks at Olympus and Hunt’s Photo & Video I got to test the Olympus OM-D E-M1 Mark II and a 300mm lens with a 1.4x extender. My regular camera is a Canon 1DX with the Canon 300mm f/4 and a 1.4x extender.
So what would happen if I shot the cameras side-by-side?
I went to my friend Lee Hoy‘s house in Ft. Davis Texas. Lee had some hummingbird feeders that were pretty active thanks to fall migration. Hummingbirds were buzzing the feeders like crazy.
My test was to set both cameras on the most fancy fast focusing settings. Lee knows Olympus so he double-checked all my setting on that camera. I know Canon so had everything set on that camera.
Both cameras were set to f/7.1, aperture priority, at ISO 500, continuous auto-focus, and rapid release.
I picked-up one camera and fired. Then I put it down and picked-up the next camera. This went on for a little over an hour. Canon then Olympus then Canon then Olympus until I was exhausted.
In the end, I took 267 photos with the Olympus and 159 with the Canon. The Olympus has a higher frames-per-second rate so there will be more photos to edit. More opportunities to capture the precise moment of action, too. That’s the plan anyway.
Both cameras held and maintained focus on the hummingbirds. I was pleased to see that the Olympus kept-up with the Canon. Both cameras also failed to focus on a hummingbird about the same rate usually thanks to operator error.
Winner? Not one over the other. They Olympus OM-D E-M1 Mark II held in there against the Canon 1D X Mark II. That should be good news for any bird photographers looking to buy the Olympus system.
