LensCoat® Sony FE 100-400 f4.5 GM OSS

I was worried about scratches on my expensive lens, but this cover fits perfectly and the material feels thick enough to handle a few bumps in the bag. The cutouts for the zoom ring are precise, so I can still adjust without any hassle.

The fit is snug enough that I don't worry about it shifting around in my bag, but it still lets me access the zoom ring easily. My lens has already survived a few rocky trail knocks without a single scratch on the barrel.

The cutouts for the focus and zoom rings line up perfectly, so it fits like a glove and doesn’t shift around at all. I’ve got a few dings on the original body hidden underneath now, and the coverage protects the finish much better than I expected on the trail.
