Some UW-Photography Contests, held during a single dive, expect from the photographer to shoot different subjects: Macro, complete fish and seascape, for example. And that is only possible with a zoom lens. But which one?
Which are you using under this conditions? Which are the sharpest in your opinion?
Nikon's 18-70mm 3.5-4.5?
Nikon's 18-105mm 3.5-5.6?
Nikon's 16-85mm 3.5-5.6?
Sigma's 18-50mm 2.8?
Has anybody compared them underwater? Any experience?
Thank you very much! Any opinion will be apreciated!
