Subal's DP-SUP renders the best corners of everything I've used, but it isn't perfect. It is huge, and heavy, and lens specific. I have mixed feelings about recommending it... On one hand it is the best underwater option for this fabulous lens, but it isn't what I'd call user friendly.

Sebastian,
My statement wasn't directed at you but I just found it interesting that a housing manufacturer like Subal would give a customer test shots only if asked. Here on WP and everywhere else, it's been the dealers and sometimes clients who've been publicly testing the ports for potential customers. I would think they should have it on their website for every potential customer to see. I'm just a little disappointed with manufacturers that way.

Hi Drew,

I don't know if I have understood your answer correctly. I will try to clarify my intention behind my question. Some time ago (march 2009) I asked Subal if there are any test shots available for this special dome port for the Nikon 14-24mm. Subal Europe (Mr. Rolf Sempert) answered my question and sent me a few test shots (plain pool shots, no test charts were used) along with his email. Now that I received my Subal ND700 this weekend I was wondering if anybody is using the Subal DP-SUP in the field and can provide some real world shots (eg. reef scenery). I just couldn't find any shots on the net (on Wetpixel) that were taken with the Subal DP-SUP. I just would like to see something different than just pool shots before spending a lot money for this port. As far as I remember this port was shown on Dema 2008 for the first time (?)

Dema 2008: Subal DP-SUP

So I was hoping that at least a few people already bought this expensive port and can show us some shots. :)

Surely it would make much more sense if Subal (and others) loaned an example of their solutions to us at Wetpixel - so we could shoot it in the field and share some results of how a product performs on real world subjects. Or failing that - if they are loaning kit to people to try in the field - encourage them to share the results.

It is great when manufacturers and dealers test these things - and most tests seem 100% objective. But it is even better when kit can be tested by those who are not commercially involved in the products.

I know someone who had the prototype 10" Subal port that he had it a year ago. He's since disappeared and not answered any of my emails. hmmmm... :)

I'm sure they do field test it on their own but many of them get caught with variables they themselves don't foresee. To stay on topic with Subal (but not single them out), I had the 1st gen 105 port that never fit properly on the ND2.
I can't even sell it because I'd be screwing the next person. Of course, they came out with a bigger port later when people started complaining.
I have beta-tested stuff but they usually NDA it so I can't share the results, good or bad. Then they release it with the same issues many highlighted in the beta-test only to backpedal later with a fix.
Problem is the logistics of setting up a field tester is sometimes a pain. I can understand manufacturers not wanting to have outside sources beta testing their products. It's uncontrolled but then again, if they have a good product, what do they have to be afraid of? :P

Hi Ryan,

thanks a lot for your work! Your shots are a lot better than the pool shots I have got!
I guess with a little bit of current the huge port will fly away like an umbrella in stormy weather! :)
By the way, what extension ring are you using?
Looking at Subal's recommended setup for the Nikon 14-24mm lens wasn't very helpful. :P

Hi Drew,

when I thought about buying a housing for my Nikon D700 a few month ago I did a lot of research on the net. After a few hours of surfing I visited Seacam's website for the first time. Surprisingly their hottest housing for Nikon users seemed to be one for the Nikon D200. My first thought was: this business has been shut down, they stoped making housings after finishing the housing for the Nikon D200 and now the only thing that's left is their website. :P O.K. , after doing a few more mouse clicks I found out that Seacam U.S.A. is more up to date and Seacam is still alive, but this is still interesting. :)

unfortunatly I do not have a testchard as you have Ryan...

I tried the Sea&sea fisheye dome with two extensionrings (40 + 22). At 30cm away from the subject the pictures are ok for me at aperture 5.6 or 8.

The strange thing was when I shot 60cm away from the subject the cornerunsharpness increased. It was terrible. I thougt the further away the better it would be.

Ryan, did you try this combination on your testchard? What was your opinion about this?

Has anyone an explanation why the cornersharpness increases when I go further away from my subject?

The problem with lens performance behind a dome is that it's quite easy to see if it works acceptably well but not so easy to see if it works perfectly. To this end I have five different manufacturer's housings and ports that I have collected over the years, which until recently were all used with 35mm film and the same 20mm Nikon lens. All were acceptably sharp. In that combination however, I can categorically state that the unlikely winner for edge to edge sharpness was the Sea & Sea with its large acrylic port.

Since I went digital, I have bought housings and dome ports from three different manufacturers and used them with Nikon 12-24, 10.5. 16 (FX) and 10-17 Tokina. Two were glass and one is acrylic. Again all are acceptably sharp but the winner by far is the Sea & Sea optical glass port in conjunction with the cheapo Tokina.

In fact I have just returned from Bali with the D700/16 and am off to BVI and have decided to take my D200/10-17 combination instead.

I guess that small manufacturers don't have the resources to really get things perfect and a degree of luck comes into play.

I see a lot of contributor's material that comes into the office that is very soft at the edges and blame that on the use of compact domes.

Small businesses sometimes take risks that larger businesses would not. Some years ago I queried the fact that the dome port of my Subal rotated too easily after one flood and one near flood. I checked my spare O-rings and found that I had a set of slightly differently sizes but nobody seemed to be able to say which were correct. I took them to DEMA where I showed them to Rolf of Subal and was shocked to be told that the British distributor supplied his own (blue) O-rings and that they were not of the correct gauge!

I buy my own photographic kit. Diving equipment manufacturers and diving services suppliers get even-handed treatment from me whether they choose to advertise in the publications I write for or not. All the equipment I get on loan is returned as soon as it is finished with. Did you know you can now get Diver Mag as an iPad/Android app?

I know this is an extremely sharp lens, but it is not without it's distortion issues at the wide end. Even topside these are noticeable, and particularly if the camera is tilted at all. On our Oceanics Whitetip trip I had the chance to compare images taken with the Tokina 10-17 and 1.4 TC to the 14-24 on a D3x and also the new Nikon 10-24 on a D200, and I preferred the the distortion of the Tokina at the 17 end (still wider than 14mm rectilinear) to the distortion of the 14-24 and 10-24 at their wide ends. These lenses tended to make the sharks look thinner and more stretched, and this can be quite exaggerated if the camera is tilted in relation to the subject. whereas the Tokina made the sharks look like they had a little more girth. I know opinions may vary but I preferred the look of the Tokina.
At the moment I've settled on the Tokina and my 17-35 as my WA choices underwater. It may be that a rectilinear can be too wide to give pleasing perspective underwater particularly with subjects very close.
You can see some distortion in my topside pics I posted earlier today. (Look at the ballons near the edge of the images)
