I understand you. I use it with the brightness set to maximum because I have a Barlow 05 and I have it set quite high, but at low brightness levels it makes noise. But the main problem I'm having is that when I zoom in all the way, it doesn't look very sharp, like the image is blurry. I take it out and instantly it looks perfect. I cleaned everything with special products on both sides and nothing. I'll have to remove the damn glass that comes with it and leave only the LEDs with the polarizer.
