I am tempted to get one, my eyesight is probably one of the worst there is, have a lot of people thought of getting one but found they eventually manage? My D90 focuses in on the live view but it doesnt seem the quickest and a lot of the the button controls go redundant, viewfinder would be nice, but..hey I've spent a lot as it is! I can view my subject ok when I get used to it, but reading the settings is a bit of a struggle but then again I have the info screen programmed to the on/off/light button toggle, I guess I'll get used to it..or will I!?
A 2nd hand Inon 45 could be a go-er or the Nauticam, the actual Aqyuatica's priced itself way out of the market for me, the others still are but.....hey! I wanna be comfortable taking my shot!
