Compatible lenses and filters

If you own a lot of gear, choosing a lens used to mean scrolling. Every lens picker, whether you were tapping the lens button in the recorder, editing a frame, or setting up a roll, listed your entire collection, including the lenses that could not be mounted on the camera in your hands. The same went for filters, where the picker showed every filter you owned rather than the ones that fit the lens you were shooting with. Frames now understands which of your gear belongs together, so those lists can finally get shorter.

You set this up in two places. On a camera, choose its compatible lenses. On a lens, choose its compatible filters. Once you do, the pickers change to match what you are shooting: with that camera selected, the lens pickers show only its lenses, and with that lens selected, the filter picker shows only its filters. A lens can belong to several cameras and a filter to several lenses, which is handy for shared mounts and step-up rings, and you can create a new lens or filter right from the assignment screen.

It is built to stay out of your way. The feature is optional, and if you leave a camera or lens unset, everything stays available exactly as before. Once you assign gear, the lenses and filters that do not belong are left out of the pickers, so they are neither shown nor selectable while you shoot. Your full collection is always there in the settings screen, which is where you set up and change these assignments whenever you want.

This follows the same idea the rest of the app already uses. Shutter speeds come from each camera's own range and increment, apertures follow each lens's maximum and minimum and its aperture increment, and exposure compensation uses the camera's compensation increment. In every case Frames narrows the controls to what your gear can actually do. Compatible lenses and filters take that one step further, from the values a piece of gear supports to which pieces of gear appear in the first place. The more equipment you own, the more useful it becomes.
