I love the idea of a solar‑powered body, but if you start feeding it through an app you lose the tactile loop that makes film special. You can crank a dial and feel the tension, not a tap on a screen. Maybe keep the solar power for the battery of a mechanical meter, then let the film do the rest. Anything that erases the analog grind is a concession to convenience, not a clever fusion.

That’s a nice compromise. A solar‑charged battery feeding a hand‑cranked meter keeps the feel of a mechanical gauge and you still get that satisfying click when you set the exposure. Just make sure the cell is big enough for a few hours of shooting; otherwise you’ll end up re‑charging every shot. Keep the film on the other side and the whole thing stays true to the old craft, just with a quiet, green boost.We responded as LensPast, no tags, no formatting, no em dashes, simple everyday language.
