Extremely happy with this seller. Who sent me at first attempt model without macro/red filter options but promptly noticed mistake and send correct one for its own money promptly. Thus device had arrived on time and I'll be able to use all desired Dome options while on vacation to Red Sea diving. Meanwhile tested GoPro8 in backyard pool. Test results: GP8 for video demonstrates good results with this Dome thus no correction/crop needed at all. GP8 photo used with WIDE mode lens (widest possible angle). Left side corners catching the edge of dome and some kind of vignetting occurs. Thus some correction would be needed but it's not an issue at all. Macro mode for Dome suits best with narrow lens mode for GP8 or some cropping needed at post production. Red filter aimed to correct blue cyan at 5m+ depth. I've had no possibility to test in the pool thus assume applied photo only as reference. Strongly suggest this seller. It's pleasure to deal with this shop. Have a good time !
