FWIW I’m mostly making a point about this because I was surprised the first time I tested a fresnel among a mix of other modifiers and found it wasn’t the most efficient (as I’d assumed it should be).

That's good feedback for sure. The Fresnel can be much more expensive and if a throw modifier works better and is cheaper, lighter and easier to use, the only reasons to use a Fresnel would be if it provides some other quality of the light beam as incentive. Might, for example, the Fresnel provide better feathering?

The main thing advantage a Fresnel spotlight has over a long throw reflector is that the Fresnel is focusable*. This is very useful.

*the exceptions to this rule are the Profoto Pro and Acute pack and head systems and all of Profoto’s reflectors; Speedotron Blackline packs with 202VF and 204VF heads , and late model Balcar systems with Zoom heads. With the Profoto Pro and Acute heads the reflector moves back and forth along the head,; with the Speedotron Blackline VF heads the locking collar on the head spins forward or back on a helical track; and Balcar moved the flash tube and modeling lighting assembly back and forth.

Very informative.   I had heard mention of softboxes with adjustable head positioning and wasn't till now sure how it was done.

Thanks for the fill.
