My light meter is around my neck 100% of the time that I’m shooting. Literally, 100%. It’s a Sekonic L-508. It’s less than $300 when you buy it used on eBay. (Notice the trend of buying gear on eBay? I rarely buy gear brand new, opting for used whenever possible.)
The Sekonic L-508 is affordable compared to the newer models, it has spot-metering capabilities, and the ambient bulb is retractable. (This matters. You’ll find out why in a bit.) If you can’t swing the $300, you can purchase the Sekonic L-358. The L-358 doesn’t have a spot meter, which you’ll need for shooting black and white film. Worth saving up that extra $75, for sure.
