Canon R5 Mirrorless — Autofocus on Hummingbirds

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.

Moving Toward Mirrorless — Sensor Size

Thanks to the folks at Olympus, I get to test the Olympus OM-D E-M1 Mark II and OM-D E-M1X.

Both are called “micro four-third” sensor cameras. That means the sensor is 17.4 mm on the long side by 13.0 mm on the short side. Contrast this with a “full sensor camera” that has a sensor that is 35mm on the long side by 24mm on the short side. (Notice the sensor is the same size as a 35mm piece of film.)

The advantage of a “micro four-thirds” sensor is things appear closer.

The Canon Rebel T6i has a “cropped” sensor, or 22.3 mm by 14.9 mm, so the same object appears farther away.

The Canon 5D Mark IV is a “full frame” camera with a sensor 35mm x 24mm. Objects appear much farther away.

I took each photo above from the same place. Each camera had a 300mm lens with a 1.4x tele-extender. That means I was using a 420mm lens for each photo but the subject was more or less magnified based on the sensor size.

The Olympus “four-thirds” sensor would mean a bird would be larger in my photo. The “four-thirds” sensor would mean I might not have to crop as much since the subject would already be bigger in the photo.

Once again, thanks to Gary Farber at Hunt’s Photo & Video for making this test possible.

Stay tuned for tomorrow’s post as I continue to explore these cameras.

Canon EOS R: My Test Drive

Thanks to the folks at Hunt’s Photo & Video I got to test drive the new Canon EOS R.  This is Canon’s first entry into the full-frame mirrorless camera market.  I am highly impressed.

The camera has a great feel in the hand.  There’s plenty of room for your hand and right thumb giving a more robust feel than the Canon M-series cameras.

The swivel screen on the back of the camera is great for ground-level macro photos.

Hand-feel and ergonomics — give the camera an A+.  The electronic viewfinder is the brightest I’ve seen.  The touch screen on the back is quick and responsive.

Yet, how about the photos.  Last year, I pushed the Canon M-series camera pretty hard when I gave it a test drive so I thought I’d do the same with the EOS R.

Notice in the photos above that there’s no fringing on the leaves when the photo is enlarged to 200%.  The grain structure looks good.

Let’s try another test.

Above is a twilight photo with the Canon EOS R on a tripod.  Enlarged to 200% on the right.

Same scene but photographed with a Canon 5D Mark IV.

In low light I can’t see any difference between the photos taken with the Canon EOS R and the Canon 5D Mark IV.

A simple comparison of photos.  The photo taken with the Canon EOS R is on the left.  Canon 5D Mark IV on the right. Both are enlarged to 100%.   I can’t see any difference in quality.

I like starbursts in my photos.  How does the EOS R’s 24-105mm lens work in the starburst category?  Not bad!

Conclusions:

  • The Canon EOS R is a “real” camera on par with the Canon 5D Mark IV.
  • There does not appear to be any differences in the picture quality between the two cameras.
  • This is not a point-and-shoot or lower quality camera.
  • The Canon EOS R is going to make a lot of people rethink their mirrorless options.
  • First-time camera owners might skip the DSLR body in favor is this mirrorless.

I’m impressed with the Canon EOS R on static subjects.  How does it handle action?  Stay tuned.
