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.

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.

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..

I like to keep as few digital screens in my camera bag as possible but this light meter has been an amazing companion. The startup time is a little laggy but not enough to be annoying. I recommend it.

The L-478DR light meter is arguably the best, easiest to use meter available, but it has one limitation: It cannot measure reflected light. This viewfinder rrplaces the ambient light dome and allows you to measure reflected light. It's an absolute necessity for landscape photography.

Pros: it does meters the light, offers bulb in and bulb out, light weight and small.Cons: terrible battery life, screen kind of hard to see in bright sun, touchscreen annoying to use, touchscreen constantly gets accidentally touched by clothing when its hanging out your heck changing your selected...

The info in the catalog does not mention a case and thus are lead to believe that you might want to buy the optional case. In fact, the meter does come with a cheap case, kind of an over-sized glass case. They need to publish the fact that it comes with this cheap case.
