In Topic: NEX Macro Option?

My eye are also not very well so I have to use mask with correction glasses and magnifying loupe on the camera screen and in manual focusing it is possible to use additional digital magnification to adjust focus.

I think that kit lenses 16-50mm, 18-55mm or just 50mm with macro wet diopters are better than 30mm macro lens.

 

I do not like to use autofocus during taking macro so for me there is no reason to change my old camera  :)

If the air which You closed under the dome will be dry then there is no reason to get any fog at any condition.

The RX100 was my previous camera. Sorry I have to time to update the informations and pictures on the website.

I was very happy with that camera and housing made by Acquapazza, so when I switched for Sony then I bought again Acquapaaza housing.

The longest port which I have is dedicated for Sony 100mm macro A mount lens with LE-EA1 adapter. 

 

I just read this article,

http://www.uwphotogr...raphy-dome-port

and because BlueWaterPhoto pointed out that limited range of macro lenses are the weakest feature of NEX system then I will try to adopt some of on-land macro tricks for underwater photography. 

 

This is my setup with short macro port dedicated for 30mm lens the same size is for 16-50mm lens and 50mm.

In Topic: uwl-h100 dome fog

02 April 2015 - 11:21 PM

I've had the problem with the dome on the uwl-h100 fogging up when getting in the water before, usually just waiting a bit with the lens in the water would sort it out as the glass cooled.

Today I had the problem that the inner wet lens was fogging up, which took much longer to cool down as it is not exposed directly to water.

Any idea how I can prevent this from happening? I'm assembling the lens in a well air conditioned room...

I had similar problem. I got the fog on the internal surface of the dome or front lens under the dome glass. I was trying different techniques including mounting the dome in a special environmental chamber :) 

At the end I did this in the car, so first I setup max heating with internal flow of air .... after some time, when temperature became uncomfortable I switched air-condition to max cooling .... when it became cold then the air should be dry, so I attached the dome on the lens.

After that there was no more fog inside the dome even when I did diving in cold water.
