Is it cosine corrected?

The L-858's retractable incident Lumisphere provides standard or cosine corrected light readings.

Does it have a tripod socket?

I think so. Not really sure. I hope that it’s not a deal breaker if it doesn’t? It’s the most awesome meter I have ever owned.

does the case that comes with the meter have belt loops?

The case has one belt loop, which fastens with Velcro.

I have already purchased the sekonic speedmaster l-858d-u and i got the unit yet i’ve noticed there is no transmitter module do i have to buy it ?

Yes, there are two radio modules available. One for Phottix/Elinchrom and one for Pocket Wizard
