pictures underwater? there is a smugmug link in the post I sent you. with underwater examples.
I did not take it into the ocean as I was not interested in using the lens long term.

yes, just like nikon ff lens on aps c. same crop factor. i.e the 35 2.8 would be 52.5mm and 55mm would be 82.5mm
So if Sony does indeed come out with a 100ish-mm macro for FE, as rumors suggest, then it would be similar to shooting a Nikon 105mm on a D7000.
The NEX series would then have 30, 50 and 100mm macro options and the FE line would just have 100mm. (or the others in crop mode).

if you are snorkeling (primarily) with occasional dives. I would really consider NOT buying that housing for your canon. Instead buy a compact (used you can get cheaper) with a wide angle lens.
Remember the number one rule for underwater photography. Get Close. A wide angle lens will let you get close to your subjects and get it all in the image. You can also shoot WA more easily with available light. Something you cannot do easily, if at all, with Macro or "normal" focal lengths
I think if you look for a wide angle compact system, you will have a lot of fun and will get more images that you will be happy with.
Although your canon has better quality than a compact, it will not take great photos with a normal lens (even at 18mm behind a flat port) with a lot of distance between you and the subject. Also, you can get spectacular photos with a compact, they are very capable today.
also a compact camera will be easier to snorkel/dive with if you aren't used to it.
A quick search in the classifieds showed this guys is selling something that would suit you very well (no affiliation)

In my opinion, i would highly consider something like this.

since you have the raw, I would say avoid the channel mixer. Multiple ways to skin the cat. I did this quickly in Lightroom 5
Exposure +1.29
Temp: 20787
Tint: +150
Highlights -100,
Shadows +100,
Whites +24
Blacks -60
Clarity +17
Saturation - to taste - strong agrument to leave it a little "blue" given that is what we see underwater and what the viewer might expect it to look like.
Reds: +81
Greens: -73
Aqua: -39
Blues: -9
noise reduction
Luminance: +50
Color: +25
Sharpening +50
Masking: 90
and the spot healing brush on the diver and fish (Photoshop would have done a better job)

The acrylic on the dome is in great condition; the aluminum has minor cosmetic blemishes. Comes with neoprene dome cover and O-ring. The Lens and Fisheye adapter are in very similar condition. Minor wear on body but glass in great shape. This combination gives 15mm equiv. on a APSC NEX 3-7 or a3000-6000.
This is a complete and very nice wide angle combination for the NEX system

Sorry to resurrect this, but I REALLY want the z240 type 4 manual. I have questions which are not answered by the reefphoto article.
Thanks, Doug

good point Steve! strobes behind the port works wonders.
I also found this talk on youtube that Alex Mustard did on Backscatter. worth having a view. he discusses why it occurs and how to combat it.

There are a ton of resources/comments/articles on wetpixel and online to help minimize it. I suggest a search on the beginners forums. There is also a great book by Martin Edge called The Underwater Photographer, which deals extensively with wide angle issues. Many experienced underwater photographers consider it their bible.
I'm no expert and am still stymied by backscatter fairly regularly given the amount of particulate in the water in Miami. However, these are steps i've used to minimize the impact.
1) Get Closer. old cliche, yes, but really does work.
2) Play with your lighting positions. two examples
a) Angle your strobes slightly away from the subject so you are lighting with the edges of the light cone. This seems counter-intuitive b/c you are not pointing the lights at the subject, but it works.
b) move your strobes a little further out from your camera. I often get hot spots b/c my strobes are too close.
Check your lcd often and adapt your angle/lighting as needed. Sadly there is no one thing that prevents it. What works in one situation might not work in others.
hope that helps you get started.

lots of people discuss using it with a tripod. another option that has gained popularity is the fibersnoot

Ah I see. so these insurance comanies are more geared towards personal health insurance vs gear insurance, though they do have the option of insuring gear as well. That makes more sense.
I might have to reconfirm this, but when i buy travel health insurance, I'm pretty sure it covers getting bent. I'm in canada, and Canada has universal healthcare, so I think that would cover it as well, though I'd likely have to pay for it myself first.
I would get travel insurance when I lived in the UK. My advice is to check the fine print, some permit diving to your certification and others limit you to 30ft/10m. Also you will need to check the amount they will pay out in case of an accident. But these are easy to spot once you know what you are looking for.

No pictoral answers as yet, would love to see all 3 compared tho NEX16mm P+FE and NEX 8mm FE and MFT 8mm FE.
The port length would still concern me with the 8mm, I reckon the pancake and FE converter and Rokinon are around the same length but as the Rokinon is 8mm I would have assumed vignetting
