So I'll make this short and sweet. I use it for cinematography, metering on set for ambient light. This meter was just too slow, the bootup time is such a drag coming from an l-758. The touch responsiveness wasn't that great, the buttons were slow to respond/load.

Performs as advertised. The touch screen takes some getting to, little finicky. Takes all the guess work out. No regrets.

I watched a couple videos on Youtube before I purchased this meter. When I received the meter I was ready to go. It worked just as I expected it to. The meter came with a strap and a case which attaches to your belt making it easy to carry. The two AAA batteries were not included.

This product works well and is easy to use. When on location and outdoors it streamlines the set up time.

Actually have not used this much yet, but I have looked over the interface and i like how it's pretty easy to use. (Just wish it had an incident meter! :( )

When I first got into photography thousands of years ago, I bought a light meter, but had no clue how to use it. Umpteen years later and I am shooting more in a studio using flash and strobes. I love this tool for this purpose.

A great addition to the meter. Helps narrow the metering angle for tele glass.

Best light meter for film. Goes up to high ISO and is super user friendly with the touch screen. If it broke i'd buy the same one again.
