I have a well used but fully funtional Letus Ultimate rig with rails, adapters and follow focus for $2,800. Killer deal since I sold my EX1 and have no use for it.
Brevis!! HUH???? The sgblade, redrock, letus, handy35 all destroy the brevis. In fact, I have done side by side comparisons, and the brevis does produce a decent pic, it's nowhere near the sg, or others. Not to mention vibrating adapters cant be stopped down in where near the spinners, overall, they cant hold a candle to a spinner.
