Choosing the right light meter for film photography depends on your shooting style and budget. This guide compares handheld options like the Sekonic Flashmate and Keks KM-Q to help you decide.
Quick answer
For most film photographers, a compact handheld light meter like the Sekonic L-308X-U Flashmate or the Keks KM-Q offers reliable metering without breaking the bank. Your choice depends on whether you need advanced features like cine modes or prefer an ultra-portable, budget-friendly option.
Ambient vs. flash metering
If you shoot with studio strobes or off-camera flash, you need a meter that can measure flash output. The Sekonic L-308X-U handles both ambient and flash, making it versatile for mixed lighting. The Keks KM-Q is ambient-only, so it's best for natural-light shooting or cameras with non-functional built-in meters.
Size and portability trade-offs
The Keks KM-Q is about the size of a sugar cube, fitting easily in a shirt pocket or on a keychain. The Sekonic Flashmate is pocket-sized but larger. If you prioritize minimal bulk for street photography, the KM-Q wins; if you want a more traditional meter with a swivel head, the Sekonic is more comfortable to handle.
Decision rules for choosing a light meter
- Do you need flash metering?: If you use studio strobes or speedlights, choose a meter that measures flash output, like the Sekonic L-308X-U. Ambient-only meters (Keks KM-Q) won't work for flash.
- How important is size?: For maximum portability, the Keks KM-Q is nearly weightless. If you prefer a meter you can hold and operate with one hand, the Sekonic Flashmate is still pocket-friendly but more substantial.
- Do you shoot video?: The Sekonic L-308X-U includes Cine and HD Cine modes for setting exposure in video. The Keks KM-Q has no video-specific modes.
