Need help with the Canon R7.... Is it a skill issue, or the camera
Canon R7
RF 100-500 L IS USM
I’m really struggling with the Canon R7 when it comes to tracking birds in low light, and honestly, even in general. The camera seems to hunt for focus constantly, even when the bird is right in front of the camera or filling a huge portion of the frame.
For example, today I had a bird filling around 80% of my frame, and the camera still completely refused to focus on it. Instead, it kept trying to focus on the rocks behind the bird and would scan back and forth rather than locking onto the bird.
I genuinely don’t understand how it can miss the subject when it takes up that much of the frame.
My main issues
- If a bird isn’t in direct sunlight, the camera has a really hard time tracking it and achieving eye focus.
- BIF (birds in flight) has been an even bigger problem. I’ve had a literal 0% success rate with BIF. The camera just doesn’t seem to lock onto the bird quickly enough, and by the time it does, the moment is already gone.
- I use Tv (shutter priority) mode because I’m usually out walking or hiking and need to be able to quickly take photos when an opportunity comes up. I don’t always have time to switch to M mode and change all my settings. A lot of the birds and animals I photograph are also very skittish, so being able to react quickly is important, and Tv mode works much better for that.
- The other problem is that Tv mode sometimes seems to expose completely incorrectly. It can be wayyyy overexposed, with white feathers being completely blown out, or it can be extremely dark, to the point where I can barely see anything. It feels like it hardly ever gets the exposure right.
- And, as mentioned above, the tracking just seems really poor. Even when the subject is large in the frame, the camera can still ignore it and focus on the background instead.
My general settings
- AF Operation: Servo AF
- Subject detection: Animals / Eye Detection
- AF Case: Case 2 (Continue to track subjects, ignoring possible obstacles)
- Lens: RF 100-500mm L IS USM
- AF range: I switch between 3m–∞ and Full when appropriate
- Image Stabilisation: First IS option
- AF: On
- Metreing Centre Weighted or Evaluate
I’ve also tried both shutter-button AF and back-button focus.
Back-button focus actually seems worse for me. It seems to hunt for much longer before locking onto the subject compared with using the shutter button.
I sometimes turn eye detection off because I’ve heard that it can help AF tracking by preventing the camera from constantly searching for the eye.
However, when I turn it off, I’ve noticed that sometimes the camera seems to refuse to track the bird properly at all.
I honestly don’t know what I’m doing wrong. I can go on an entire hike and come home without a single usable photo.
The biggest issue seems to be when the subject isn’t directly lit by the sun. If the bird is in good, direct sunlight, the camera generally does much better.
As soon as the bird is in shade or the light is lower, the AF seems to struggle massively.
Is the R7 genuinely just this bad at tracking birds in low light and with BIF, or is there something I’m missing with my settings or technique?
I’d really appreciate advice from other R7 users, particularly anyone using the 100-500L for birds and wildlife.
