Thank you so much for your answers and quick response. I just ordered the Kenko 1.4 TC and will order the 20mm extension tube.

Which model Kenko is used with the Tokina 10-17mm? The Kenko 1.4x Teleplus Pro 300 or the newer Teleplus HD (PRO) 1.4X DGX? I can get a Pro 300 for very little money

I have looked into the posibilities today, and the strange thing is that there is almost no market for second hand 1.4x teleconverters, but there is for 1.7x teleconverters (a bit of a unique magnification factor that Nikon build in 2004.) So I am now wondering if I shouln't use the Nikon TC-17E II with a 30mm extension tube and get a 17-29mm (25.5-43.5mm FF) result but at the cost of it becoming a F6.3-7.1 lens.

That is not such a bad idea indeed. It is a little bit short indeed, but you are right that in all likelyhood you don't get any sharp pictures beyond 30mm full frame. Corner sharpness is much less of an issue on this dive as you pointed out, unless they happen to get so close they do end up filling most of the frame. I will certainly consider this option as it only means a slightly different zoom gear and an extension ring. Thanks

I want to go dive with thresher sharks at Malapascua, which is dark and the sharks stay generally at quite a distance. I read the Thresher shark at Malapascua with M43 discussion about lenses for this dive and I am now considering a Sigma 18-50mm F2.8 EX DC Macro lens for this. I am using a Hugyfot housing and have the 10-17 Tokina fisheye and the Nikon 40mm macro. Neither of these lenses are ideal for this type of dive. Other than the focal length being quite flexible, the relatively good aperture for such dark conditions, the ability to focus rather close and the rather cheap price. The main advantage of this lens for me is that it is recommended to use the 7" dome port in Hugyfots port chart, which I already own for the Tokina fisheye. Another option is the Sigma 17-70mm F2.8-4 DC C OS HSM which according to Hugyfot also fits well behind the same 7" dome port. The slightly wider FOV makes this one an option as well. However, I am skeptical about this, how can you put an 18- 50mm (or 17-70mm) lens behind a fisheye dome port and expect good results. Anybody has experiences with similar weird lens-port combinations that might give me hope this might actually work?

Thank you, sorry I missed this discussion from before. Very interesting, but indeed it looks like I need a new lens and port for this trip ideally.

Hi, I am planning to go dive in Malapascua with thresher sharks (we hope they show up of course). Now I wonder if people with experience diving there can tell me what lens I should best use for this dive and if for example strobes are any use or the distance is likely too great to be of any benefit there. At the moment I have a 40mm macro and a 10-17mm fisheye, and I fear neither is well suited for this dive. Thanks in advance for your advice.

It does seem to me that with the 64.5mm length from the technical specifications of the lens and the 2 cm extension (as measured by Nikon Service upon my request in their lab) the maximum length of the lens would be about 85mm, which would require a L90 indeed. The shortest extension is 20mm, so the L90 without extension would be shorter. Did you consider the MP 60 macro port for the 60mm lens? They are more expensive, but the conical shape and option to easily attach M67 Flip Adaptors for a wet macro lens looks attractive

I own a Nikon D500 with a Hugyfot housing. I currently use only the Tokina fisheye with it underwater, but I want to also shoot some Macro with the Nikon 40mm f2.8 DX lens. Unfortunately, Hugyfot has a bit of an incomplete port chart and this is one of the lenses missing. This lens is a bit smaller (5mm shorter and thinner) than the Canon EF-S60mm f2.8 for which they advice a FLP L70 flat port, but unlike the Canon lens, the Nikon lens extends when close focusing (by 2cm) Does anyone have experience using this lens on a Hugyfot house and can you tell me what port used. In general, what is the optimal distance between the front element of the lens and the glass of the flat port? As close as possible or is there some gain in having a bit more space?

Hi, I am considering switching from my TG6 setup to a Olympus E-PL10 system with UOI housing. I currently use a Weefine wfl 02 wet lens with 52 mm mount on the PT-059 housing. With the new housing I have 2 options: - use a dome port with either the 8mm fisheye or 7-14mm rectilinear lens (4inch or potentially 8 inch) - use a wide angle wet lens like the UWL-09Pro on the default 14-42mm lens, potentially moving to a 12-60mm later The certain advantage I see of the dome port solution is that it allows split shots. The advantage of a wet lens is the option to switch to macro if you suddenly encounter a seadragon or something during the dive. However, I do not know what is generally going to give me the better image quality underwater? Does a dome win out in terms of corner sharpness? Thanks for your help

Hi, I am a AOW diver with a passion for photography but above and below the water. My current kit for underwater photography is a TG6 with Weefine wfl 02 wet lens and single Z330 strobe. However, I am in the market for a more advanced setup with a larger sensor, without compromising on ease of travel and without breaking the bank. My eye was caught by the Olympus P-EL10 with AOI housing as it comes with vacuum system and LED strobe trigger and is almost same size as my current setup. But I have many questions about some of the key choices with regards to what to do about lenses and ports. Regards, Erik
