I also would advise against this purchase. You should look at the used market and get something that can be repaired, serviced and upgraded. 

In Topic: help ASAP...missing retainer clip on button in housing

Thanks Bill...tried it.  Would not pull a vacuum, so I thought not putting it in the water was the better choice for tomorrow. Hopefully I can find a retainer clip on the island somewhere tomorrow.  




Hi Pam

i agree, no vacuum = no diving with housing = no flooding = disappointed photographer 


much better than flooded camera

Hi Pam 


Are there any spare parts on board??? Ikelite users probably use the same C Clip?? if not you might get buy with placing a proper fitting washer on the shaft and then twisting some fine wire in the grove where the C clip is supposed to be. I hope you have the rubber / vinyl cap also. this may work. 


Also if you don't need the button or another button remove the button, remove the spring reinsert the button and either use the wire or tape solution you suggested. 


A vacuum system would also help but it may pull the button in and activate that function on the camera. 


best of luck, I am sure you will have spare C clips on the next trip.

If you conserved the sensor plane distance to target rather than distance from front of dome would you get the same difference in coverage? If so you may have made a breakthrough. Many of us use wide ports rather than hemispheres with fisheye lenses and may have been getting more subject magnification without knowing it.


The distance from the sensor to the subject did not change as the housing was mounted on a tripod with a quick disconnect. The tripod was never removed from the pool and did not move during the session so the distance from the sensor to the subject remained constant.  The subject / target was suspended in front of the tripod. The reference distance from the front of the dome to the subject of 18" is just a reference distance.


If you research the subject you will find that it is known that a full hemispherical dome will provide a wider coverage than a smaller section of a larger dome. Yes if you have a wide angle lens fish-eye or rectilinear and you are not using a full hemispherical dome you are not getting the maximum view.

Below are two pictures taken with the ikelite housing and the Tokina 10-17 lens set at 10mm. The first picture is taken with the ikelite dome and the second one is taken prototype precision dome. Both pictures were taken from the same location, withe the camera mounted on a tripod with 18" between the front of the dome and the same subject. I have full size images but I loaded these into the editor and re-sized them only. I hope to be able to get some pictures with both domes at 12mm soon. 



How would the coverage compare if the test photos were taken underwater? Would it change much from a surface test?

The pictures were taken underwater. The domes would not effect the picture in the air except for the vignetting. If you will notice the ikelite has a smaller field of view than the prototype dome. You can tell this by the distance between the white Velcro strips on the background as well as the apparent size of the background.
