  1. Leepix, Do you mean you have camera and housing already that you want to use? Alex
  2. Hi Nick. I’d be a little wary of the G7X if I were you, it does not behave like most other compacts so needs some consideration. If you are thinking of going wide angle, the G7X is particular in that its lens is shorter when at its widest. The result of this is that if you screw a wide angle lens to the front of the standard port, you are left with a large air gap between the camera lens and the port glass with a result that the corners of the image become very soft and out of focus with heavy vignetting around the borders of the image. The alternative is to zoom in which then means you lose much of the benefit of the wide angle lens. Nauticam have overcome this issue by offering interchangeable ports for this camera, a shorter port for wide angle and a longer port for macro. When you have the short port installed, you cannot zoom in beyond about 40mm as the lens extends and hits the glass. This does mean that you lose flexibility that you would normally expect with a compact camera but you do end up with good image quality for both wide angle and macro. As far as I’m aware, other manufacturers do not offer a similar solution. We have sent a setup to a French magazine, Chercheurs d’Eau, who are currently running tests with the Nauticam, Isotta, Recsea and Ikelite housings for G7X with a variety of wide angle lenses so this will be worth watching. If you are looking for flexibility to change from wide to macro underwater, I’d still personally think the Sony RX100 Mk2 is the winning choice for underwater. This camera though does not perform well underwater for white balancing and the flash recycle time tends to be longer than the Canon.
  3. I have a Nauticam Rx100ii here in front of me now and I cannot find a control that I don\t have access to from outside the housing.
  4. No, the brackets have been redesigned to enable you to use T-plates on the handle tops, and keep the brackets.
  5. Nauticam now have a version of the handle plates which is compatible with the T-plate mount.
  6. Nauticam also has a 140mm glass minidome for the mirrorless mount.
  7. Peter Rowlands from UWP Magazine uses a GX7 with the 14-42 PZ lens, the 35mm flat port and wide wet lenses for his video. I think you’d have a problem with IQ if you use a 45mm port, that 10mm of empty space on the inside of the port will not be favourable for your image quality.
  8. Hello, Where are you based? You are welcome to come and have a look at one and I can talk you through if you are near us in Bournemouth. Alex
  9. I love the bait fish schools, but then I’m partial to that kind of thing! Glad you made it home, sounds ‘epic’.
  10. You will need the Sea and Sea to either Sea and Sea or INON fibre optic cables. The Nauticam to .... are for the DSLR housing range, the Sea and Sea to ... are for the compact and mirrorless ranges.
  11. I was very pleased with the D750 in Raja Ampat last week, small and compact, excellent image quality. Giving up my D7100 now.
  12. Thanks Alex, much credit to your good self for the teachings and putting us in the right locations last week.
  13. Hello all, I’ve just come back from an Alex Mustard workshop in Raja Ampat where I was predominately using a 140mm minidome on the D750. I was using it with the Sigma 15mm and sometimes with the 1.4x Kenko teleconvertor. I have to say that it has changed the way I think about FX underwater as I love the practicality of minidomes but did not want to compromise on quality. I am very pleased with the corner sharpness of the 140mm even up to F7.1 with the Sigma 15mm. Here are some images taken with the minidome. 1. D750, Sigma 15mm, F9, 1/60, ISO 500, 140mm minidome 2. D750, Sigma 15mm, F11, 1/60, ISO 500, 140mm minidome 3. On peut s’approcher très proche au subjet avec le minidome D750, Sigma 15mm, F11, 1/125, ISO 320, 140mm minidome 4.

Nemo school, D750, Sigma 15mm, 11, 1/80, ISO 320, 140mm minidome I hope you enjoy seeing them even half as much as I did taking them.
  14. I found this thread http://www.dpreview.com/forums/post/53070031 Still looking for answers for you Alex
  15. OK, so your 12-50 lens will focus fine throughout the range in the 4” semi-dome port? Interesting, we’ve had issues here with that.
  16. Alex Mustard is currently in Egypt doing a review of the D750 camera and Nauticam housing. His conclusions will be interesting regarding this camera underwater
  17. This anemonefish shot is the 12-50 with a wet wide angle fisheye lens, not very good in the corners. http://www.scubatravel.com/photography/reviews/EM5flatportwetlens.html The 12-50mm lens will fit in the 4 inch semidome port from Nauticam (for the 9-18mm lens) but seems not to be able to focus between about 35-50mm. It will give you more field of view than the flat port you currently have but can only be used at the wide end of the lens.
  18. Used on about 30-40 dives each, very good condition, two scratches on EM10 rear window but nothing serious. Cameras also available if needed. UK/France based NA-EM1- £1100 NA-EM10 - £750 Both will come with a year warranty.
