We covered a lot of questions submitted by our little community today including items on audio to video sync, managing reverse with reflection filters, recording live music, battery life of the Zoom F8, the Zoom F4, wind covers/blimps, and several others.
One reflection filter I have experience with is the sE Electronics Reflexion Filter Pro. I'm not in a position to say this is the ultimate reflection filter to manage reverberant rooms, but it works pretty decently.
We discussed the Rycote Cyclone wind cover for recording outdoors. This is the medium model which fits most short shotgun mics like the RODE NTG2 - 4, Sennheiser MKH416, Schoeps CMIT5U and most other 28cm long shotgun mics.
A more budget friendly option which costs less than half the price is the RODE Blimp. It is a bit heavier, needs a furry cover in lighter wind than the cyclone, and takes a little longer to open but gets the job done nicely.
