Canon 8-15mm f4 Testing; UW Cozumel, Mexico
Testing the new Canon 8-15mm f4 at about 13mm f11 with Seacam 4" fisheye dome port and 25mm extension at 80fsw, Palancar Gardens, Cozumel, Mexico. Great color (Ikelite 161s). Some vignette and corners/edges soft. Probably a couple of things I can do to fix it.
