How to Choose a Light Meter for Film Photography

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.

Product facts

  • Keks KM-Q Light Meter (Black, Top Display): The Keks KM-Q Light Meter is ultracompact with an aluminum housing and a 0.42" OLED display, designed for analog cameras without a working light meter. Its tiny size means you can always have it on your camera strap or in a pocket, making it ideal for on-the-go metering.
