Shoutout to switching to manual light checks on every job

I used to just grab my digital light meter for all camera checks, but after two cameras came back with weird exposure, I HAD to stop. Now I make myself do a full manual light test with a known good body for comparison. It adds maybe five minutes per repair, but the difference is HUGE. Just yesterday, I had a Pentax K1000 where the manual test caught a sticky shutter curtain my meter said was fine. Catching that before the client picked it up made me feel so SMART. I'm three weeks into this new routine and zero comebacks so far. It's turned into a habit I don't even think about anymore. Honestly, slowing down for that test has made my repairs way more solid. Maybe give it a shot if your meter readings ever seem off.

Exactly, those meters just read light hitting a sensor. They don't know if a shutter is moving slower because of old grease or a weak spring. The meter sees the right amount of light got through and calls it good, but the timing is all wrong. That's how you get a perfect meter reading on a shutter that's actually dragging. The physical action is half the battle with old cameras, and a light meter can't feel that. You're basically just trusting the electronics to guess about mechanics.

Honestly though, that sounds like a ton of extra work for one weird case. Digital meters are right like 99% of the time, and that five minutes per job really adds up over a week. Most of the time you're just confirming what the meter already told you, which feels like busywork. I'd only bother with a manual check if the camera had a known issue or the meter reading looked strange to begin with.

Older camera springs lose tension after decades, something digital meters never factor in. They measure light exposure but can't feel the physical drag of a worn shutter curtain. That's why skipping manual checks on vintage gear is a gamble with every roll.

Wait, your DIGITAL meter said the Pentax shutter was fine? That's actually wild to me. Those things are supposed to catch everything. It's crazy that a physical glitch like a sticky curtain just slides right past the electronics. Makes you wonder what else those meters might be missing on older gear.
