In Topic: Aquatica 40D internal rotation system

Dimitris, it looks like a Canon 30D housing, when you push the plate with the rubber wheel, does it spring back? there should be a spring underneath the flat plate to create some pressure on the control of the camera, its possible that it fell, let me know at jean@aquatica.ca, we should be able to get you back in the water with the housing soon.

Jean,

 

 

Does the same config (18453 (28.5mm), and the AF port 18428) will fit the new, 

105mm F2.8 EX DG OS HSM Macro?

 

We never had the lens in for evaluation, but according to the Sigma site, it is 126.4mm versus the Nikon 105mm VR wich is 116mm, that is a 10mm difference, I would go for the 18462 just to be on the safe side


In Topic: Panasonic GH4

Regarding longer name, i'll agree with you Davide as long as its not a bunch of letter and number all together, try quickly repeating Panasonic Lumix DMC-GH4  five time in a row :-)

 

We got the GH4 a few days ago and had already being working with the GH3 for the initial design of the housing, they are quite similar camera indeed, but definitely, with 4k, access to the video features on this camera need to be taken seriously in the design.

Kadu, I just e-mailed you the procedure for the flash.

 

Oktay, this allows the camera flash to trigger in the lower position (as opposed as having to raise it fully), keeping the flash down allows for a substantial reduction in height of the housing, it is the same procedure used by Olympus.


In Topic: Deep Wreck Project - lens-port combo?

05 March 2014 - 05:12 AM

Hi Jean, thanks for your comments. I certainly would not expect Aquatica to endorse this madness, and clearly this is done entirely at my own risk!

 

However I am interested whether you agree that the 4" hemispheric glass port should have a theoretical higher pressure tolerance than the larger acrylic domes, which I believe have been known to pancake or invert at depth?

 

With the lens shade shaved, this port is optically acceptably matched with the Sigma 15mm?

 

Thanks

Harry

 

Well the 4'' does have a small radius which is in this case does work for you, on the other hand, I have yet to see an acrylic dome invert itself, be it a 6'' or an 8" !!! 

 

Such a small dome on a full frame camera will be a tough one, typically small dome are designed for shooting up close, with a cropped sensor (shorter focal length and smaller image circle) at the minimum distance with the smallest of aperture, you will be shooting a wreck at some distance on a full frame at close to, if not, full open aperture. you will be seriously out of the comfort zone of this dome design Harry.
