Keks KM-Q Reviews

Excellent in daylight on my Hasselblad 500c/m

By Craig

I have a custom hood on my Hasselblad 500 that allow me to mount the meter on top of the hood. This meter worked fabulously in this mode using the standard waist level viewfinder. Speeds up my shooting just a bit. Even in full daylight on the edge of a beach, no issues reading the display.

Works great for its size

Popped one of these bad Larrys on my M2 and it’s been working amazingly. I love that it’s small, rechargeable, and sits right on the cold shoe. Doesn’t perform as well as a full size Sekonic meter, but for the convenience, it’s nice.
