Hello, attached you find a photo with reflexions (I marked them in addition). Can you tell me where this is comming from and how to avoid? Just a sun shade missing? Was the sun in the edge a problem? Is somehow light coming between relay and front unit? I photographed with Sony A1 in Nauticam Housing, Focus Unit with 67mm bayonett, Relay Lens and 130 degree front element, Strobes clear behind the front element of port. Thanks in advance

Hi - what you are seeing is lens flare - a common problem with the emwl optics. Personally I use the lens shade on my 100mm objective lens, the downside is you cannot get quite as close to the subject. Another option is to cut out as much ambient light as you can (high shutter speed / low iso). The 130 degree is a much bigger lens and the shade will be even bigger! Sad to say that what you see in your pic is a classic EMWL problem!

All the best - enjoy using the system - once you get used to it, it is a great lens set up.

Hi John, thanks a lot! For me it feels like a mirrored image in my photo of the front element of the port and not just flare. I will get a sun shade and see how it works with distance and this ugly effect...

Not a flare but rather looks like the reflection of the camera lens (inside the housing) into the front glass.

I don't know for the specific case of the EMWL but in wide angle photo, it used to happen with some dome ports (particularly the non optical glass ones) when shooting in the sun light.

You need to prevent shiny parts inside your housing to reflect sun light esp the front of your camera lens, I used to stick some non reflective black felt material around the camera lens front so it limits the light reflection. Once again I don't know whether this workaround would operate with a EMWL.

Hi Luko, thanks for your response: I had also more the feeling of a reflection but I dont know how a real reflection could be possible... I will try the sun shade first and guess this is the solution... But I post in here if I can get rid of this with a sun shade! shooting directly in the sun was by the way no problem...

As @Luko wrote I had to put some black masking tape on the front of lens. I was getting all the lens writings reflected on the dome. Just try it.

Hi Davide, thanks for your tip! I am wondering: Was it also with an EMWL or in a non wet lens and a normal port? So you covered the macro lens?! Thanks in advance

In my case it was the Lumix 12-35 in a 6" acrylic dome. But it had the same problem my buddy on a Panaleica 8-18 mm in a 230 mm glass dome.

Never a problem with macro but the emwl is a complex lens (3 parts) so who knows. The posted image feels the same...
