What's new in M43 Lens Database

Fix what you typed, photograph what you own

• Edit your custom lenses. Added a legacy or third-party lens and made a typo, or want to correct a spec? Custom lenses are now fully editable — not just add-and-delete — and your My Kit ownership and shot notes follow the lens even if you rename it.
• The lens-name field stops fighting you. Autocorrect is off when you name a lens, so "Laowa" stays "Laowa" instead of turning into "Lakes."
• Add your own photos to any lens. Tap the Photos icon on a lens card to attach your own shots — product photos, MTF charts, or pictures from your actual copy. The icon turns blue once a lens has photos, so you can see at a glance which ones you've documented. Works on every lens, owned or not.
• Lens-card buttons now sit in fixed positions so the same action is always in the same place — muscle memory instead of hunting.

Thanks to drdul on the mu-43 forum, whose feedback drove the editable-lens and autocorrect fixes — and who confirmed the update after release.

Body cap fisheye, and a search box you can close

• New lens: the Olympus 9mm f/8 Fisheye Body Cap joins the database.
• The database search field now closes properly. A clear (✕) button empties your search and dismisses the keyboard, there's a Done button above the keyboard, and scrolling the results dismisses it too — no more keyboard stuck over the lower half of the screen.

Custom lenses, photos on notes, and a bigger database

• Add your own lenses. Legacy, adapted, and third-party glass that isn't in the bundled database can now be added by hand — and it works everywhere the built-in lenses do: DOF tools, comparison, and shot notes.
• Attach a photo to a shot note. Pin a reference frame to any note so you remember exactly what you shot.
• Seven more lenses join the database (now 80), including the OM System 40-150mm f/4 PRO, the 12-50mm EZ, the 17mm pancake, and the weather-sealed 17mm and 25mm f/1.8 II primes.
• Macro/magnification figures cleaned up across the whole database — every lens now lists its true Micro Four Thirds magnification, not the doubled "35mm-equivalent" number some spec sheets headline.
• An "I/II" badge marks the few lenses whose Mark II version is optically identical, so you know one entry covers both.

Reinvigoration

• A complete visual refresh. Liquid-glass cards, gradient backgrounds, per-brand color accents, weather-resistant and stabilization badges, and lens weights at a glance.
• My Kit dashboard. See your collection's stats, a focal-coverage chart, a brand breakdown, and a heat map of which lenses you actually shoot the most.
• A visual DOF diagram drawn to scale — camera, subject, and the in-focus zone with near and far limits, updating live as you adjust.
• A richer lens database. Every lens now carries real specs — weight, size, weather sealing, and image stabilization — sourced from manufacturer data.

Lens companion

• The app leads with your lenses, not the calculator. It now opens to the lens database — the library and your collection are the point; depth-of-field is a built-in tool, not the headline.
• Everything connects. Tap any lens to load it into the DOF calculator; tap a matching lens in the DOF results to jump straight to it in the database.
• Compare two lenses side by side, each with its own focal length and aperture, sharing a focus distance.

Where it started

Before the 2.0 refresh, M43 Lens Database grew from a depth-of-field calculator into a full Micro Four Thirds companion. The foundation laid in the 1.0 era:

• The shot-notes system — document what you shot, with lens-aware settings and live DOF math, searchable across every field.
• Export and sharing — export your notes as CSV, JSON, or Markdown, and share any single note straight to Messages, Mail, Files, or AirDrop.
• The lens database and DOF calculator — the original core: Micro Four Thirds–specific depth-of-field math, lens matching, and personal ownership tracking.
• Onboarding, settings that persist, and rock-solid lens identity so your collection and notes survive every update.
