The knurling on the Breakthrough filters is also a cut above that on others. It's much easier to get leverage on the Breakthrough filters.

No problem using them with Fujinon gf lens hoods?

None that I've noticed.

In comparing the Breakthrough and Zeiss T* UV protective lenses, one difference in their respective transmission curves caught my eye. The Zeiss T* seems to abruptly cut off light below about 405 nm whereas the Breakthrough (depending on how the part of the curve not shown actually is) UV protective lens looks like it may transmit light down to 350 nm,

Zeiss T* Protective Lens

Breakthrough UV2 Protective Lens

or so. These are screenshots of graphs from the their respective websites . I’ll try to include them here. Don’t know if this would have a discernible effect on photos?

If it did matter, it should only matter for film. Digital cameras have a UV+IR cut filter over the sensor, meaning all the UV that the manufacturer decided needed to be blocked is already being blocked. This is why B+W sells a “clear” protective filter in addition to UV. Doesn’t make much difference either way.
