One thing I like about the sekonic studio delux is the lumisphere faces towards me instead of away from me. Is there an updated version of this meter that takes modern batteries?
The Studio Deluxe (L398) does not need batteries of any kind. Its solar powered. The great thing is the batteries never go bad when you're out working; the bad is that it has poor low-light sensitivity. I regularly work in light too dim for it, which is why I use a Minolta Flash Meter VI. Uses AA battery, has both incident metering and one-degree spot, and works in pretty low light. Its not small though, none of the good professional quality meters are. Sekonic did make a few AA powered shirt-pocket size digital incident meters like the Digilite F but they're not made anymore.
