Oceanics are dangerous! There was a recent fatality in the Red Sea.

Nice shots Marcus! Is that the new Nikon 10-24? Have you shot other wide rectilinear zooms with the same set-up (e.g. the Nikon or Tokina 12-24, the Sigma 10-20 etc.) and if so, what are you're impressions with the 10-24 compared to the others regarding sharpness?

cheers

Christian


Hi Christian
Yes that's the new Nikon 10-24. I like it. I don't think edge sharpness is an issue. Lighting, composition, camera settings and how you approach marine life (i.e. your own skills) make much more of a difference. I've used the 12-24 and the 10.5 also. The 12-24 in my opinion has been superceded by the 10-24 because it lets you get that much closer. The 10-24 focusses slightly closer also (about 25 cm I think) and is exactly the same size, except it's not internal focussing so the length changes slightly with different focal lengths. It also has slight less distortion than a fisheye like the 10.5 which you can use for different effects. So for me it's replaced my 12-24.

Thanks Marcus. I did not realize you had the 10-24, I would have liked to look at it. Glad to see it worked well underwater. Did you use it with a diopter? How close did it focus? I think your shots do show some 'thinning' of the shark close up. Probably a matter of preference, as to how one wants to depict the animal, or how someone sees them being best represented.


Hi Jeff. No I didn't use a diopter. It focusses closer than the 12-24 in air; 24cm vs 30cm. Yeah there is some barrel distortion but less than for the 10.5. Nothing that can't be corrected by software. Personally I think that the advantages of reducing the water column far outweigh the distortion.

Jeff, thanks for bringing up the subject of lens choices. I split my time between the 10.5mm and 10-24mm and haven't really paid attention to the differences yet. I just bought the 10-24 before the trip and hadn't used it much yet. Looking back at the images I posted and therefore liked, I was surprised that 5 out of the 6 were taken with the 10-24mm (at 10mm). Only the 5th image was taken with the 10.5mm. Thus I'm pleasantly surprised at the quality of the 10-24mm DX lens.

Thanks Alex, that's what the Oceanics are most of the time..in your face! Or the back of your head if you're not looking. And thanks for giving the game away! I didn't realize you were in it twice. Yes, that's a composite shot. I didn't have a good over and under in the same shot so I merged two photos together as I showed you on the boat.
