merg 0 Posted July 15, 2011 For optimal corner sharpness on 10-24 dx, anyone know if a diopter needed if using an 8" acrylic Nauticam Dome? Heard somewhere that +2 was best with a glass dome but wondering if anyone have experience with specifically an 8" acrylic Share this post Link to post Share on other sites
tdpriest 115 Posted July 16, 2011 An educated guess would be to start without a diopter with a big dome: the awkward Nikon 12-24mm f2.8 is quite happy behind an 8" dome without a diopter. Tim Share this post Link to post Share on other sites
