School me on speedboosters
6 months ago

I have a new GH4 and am using a 7-14mm on it right now.  the lens is sharp, but perhaps a bit too wide (I was using a 12-24mm on my D5300 before, and it was just right.)

I am considering moving to a new lens - some thing that will give me an 18-36mm equivalent FOV.  I was looking at the sppedbooster and using the 12024mm, but I cant figure out all the info on manual settings required with it, and how to calculate what my effective FL's will be with a given lens.

Please tell me how these things work.  THanks.
