Weird bug with animal detection

[Ryan Smith]

I recently got the A7R5, switching from being a Nikon shooter. I just had a weird bug that I wonder if anyone has experienced. I switched it over to animal/bird detection and for some reason it wouldn't detect my dogs as an animal subject, and I had plenty of light. It had no issues previously, I have a big golden dog that is super easy to detect. It acted exactly like it does when trying to take a dog picture on human detection, it just used a standard AF point with no subject recognition. I tried switching to just animal no bird detection with no difference. I turned the camera off for a bit, and when coming back animal detection worked perfectly, I can't recreate the issue. And yes I was definitely on animal/bird detection. All my animal detection settings are on default. It really felt like a bug because I kept trying everything to get it to detect the dogs and it just wouldn't until a power cycle. Has anyone else experienced this? As long as it doesn't happen with humans it's ok with me.

That's odd.

Perhaps you need to tell your dogs to stop wearing clothes, sunglasses, and hats?

I've not seen that behaviour on mine, and I've had it since last November. The Bird/Animal detect is very good indeed.
