In Topic: sony 6300/6500 with zeiss 16/70, anybody

I have no knowledge of the usability, reliability and durability of Meikon housings, but the cost is of course going to be a lot less than for the excellent Nauticam ones. I agree that the Sony 10-18 is a fairly affordable lens that delivers pretty good results together with a degree of flexibility, and it is what my daughter uses for much of her underwater wide-angle work when she isn't using a fisheye. In my opinion it would be a better option than the Z 16/70 for most wide angle work because of its much wider field of view and ability to focus on subjects close to the dome, but of course the OP already has the Z 16/70. Incidentally the Sony 10/18 also works well behind a 7" dome port on the Nauticam system. The 10/18 is a bit too wide for fish portraits apart from the very big or perhaps some bottom dwellers that allow you to get very close. It all comes down to what type of shots you are looking for.


Of course Ikelite also already produce a plastic interchangeable port/lens housing for the A6300 that is substantially cheaper than the Nauticam system: http://www.divephoto...kelite-housing/


When I changed from an Ikelite system to a Nauticam system a few years ago, the improvement in ergonomics and pleasure of use was quite considerable.

Hi Antonio,

The Zeiss 16/70 is a great travel lens and although a little bulkier, it is far better optically than the 16/50 PZ. My family and I have used both lenses extensively with A6000 and A6500.

The Z 16/70 works fine behind a 7" dome. We use a Zen glass dome. It doesn't require a diopter and the corners are OK with the usual caveat of the need to stop down when using a dome (at least f8 to f11 depending on your personal sharpness standards).

The 16/70 range underwater on an APS-C camera is a bit of a Jack of all trades but master of none. As a rectilinear lens, at 16mm underwater, it is not very wide but still fine for reefscapes etc. although a fisheye lens would allow you to get a lot closer and provide more dramatic perspectives. This focal length range does work well for medium to large size fish portraiture and for catching the more shy large pelagics. The greatest drawback of this lens underwater is that it doesn't focus close. Unlike say the Sigma 17/70 macro on a cropped sensor DSLR, this lens just doesn't cut it for macro or anything small, so full utilisation of the versatility of the zoom range is negated.

Although I haven't tried it, the Nauticam WWL-1 wide angle conversion lens is said to work very well in front of the kit 16/50 PZ and flat port and provides full zoom through and up to 130 degrees angle of view. The sharpness is apparently remarkably good despite the limited optical quality of the kit lens.

"I was using it without the port shades and the lens hood, because I had a zoom gear on it"



It hadn't occurred to me to put the lens hood on the lens within the domes, so I tried that out today at home. On the Nauticam system, the lens hood will not pass through the N120 housing throat so has to be mounted from the front after the camera has been installed and before mounting the dome. That works fine with adequate clearance for the Nauticam 210mm dome and 20mm port extension. However there is insufficient radial clearance for use with the Zen DP-100 dome and the recommended 30mm port extension. There will probably be adequate clearance using larger Zen domes. The Nauticam zoom gear does not prevent mounting of the lens hood. It would be interesting to find out if using a lens hood within larger domes avoids the flare that is apparently sometimes an issue using full frame without external dome shades.

Alex. I have recently taken about 560 images underwater with the Nikkor 8-15 fisheye on the DX format D500, around 230 of which contained partial or full sunbursts or dappled light. Most were taken with a 210mm Nauticam acrylic dome but a few were with a Zen DP100 dome and a few again were taken in conjunction with a Kenko 1.4x TC. Focal lengths varied through the DX applicable zoom range and there are a mixture of horizontal and vertical format shots. None of the images show any hint of the flare seen in your and Adam’s shots. Many of the sunburst shots were taken fairly shallow – a few at 3m. or slightly shallower. Probably the relevant difference is that using DX, I didn’t need to remove the dome shade but I didn’t use the lens hood.
