I use this meter to set light levels for stage lighting applications...I will on occasion use it for strobe photography...I have owned a number of meters over the last forty years and I very much enjoy the touch scene menus..

The meter is fast and accurate. You can do just about everything with this meter. I am mostly just using this for my strobe and flash exposures and it is spot on. My location photos are so much better for using this meter to set my strobes/flash.

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! :( )
