B + W Filter Company T-Pro 007M Clear MRC Nano Filter 77mm

Lens protection without image degradation

The B+W 77mm T-Pro 007M Clear MRC Nano Filter provides a colour-neutral, highly transparent shield for camera lenses. It adds no filter effect and creates no measurable light loss, so it can stay mounted permanently. The 16-layer MRC Nano coating repels dirt, water and fingerprints while keeping reflections to a minimum. Photographers who want continuous front-element protection without altering exposure settings will find this filter suited to daily use.

Replaces basic clear or UV filters that add flare

This model upgrades from uncoated or single-coated protectors by using a 16-layer multi-resistant nano coating that cuts ghosting and flare in backlit scenes. The ultra-slim Titan mount avoids vignetting on full-frame lenses down to 17 mm, a limit where thicker rings often clip the image circle. The jump is worth it when you shoot wide angles in challenging light and need the filter to stay invisible optically.

Limited by 77 mm thread and slim-mount constraints

The filter fits only lenses with a 77 mm front thread; step-up or step-down rings add thickness and can reintroduce vignetting at the wide end. The slim Titan mount leaves no front thread for stacking another filter or attaching a standard lens cap, so a push-on cap or hood must be used instead. Buyers who need to stack a polariser or ND filter, or who rely on threaded caps, should note these mechanical limits before purchasing.
