Dome 8" AND 2.8/24mm ??

Recommended Posts

Hi,

 

i'm using a 2.8/24mm CANON with an Ikelite dome 8" !

But my problem is, i've got some vignetting effect in the corners.

So what can i do ?

Maybe i need a specific extended Dome but which one ?

Thank you for your help...

 

Valery.

Hi,

 

If you're seeing the black corners of the port, then the port extension is too long. You should order a shorter "stalk" for your port from your Ikelite dealer.

thank you James for your help,

in fact my problem is not about black corner, but optical distorsion in corner !!

May be i'll try to show you a picture to understand better what is the problem.

Thank you and have a nice day...

OK, well that's not vignetting then. Vignetting is when the corners get darker.

 

The problem you describe is still usually due to using the wrong port extension though - something to look into.

 

Cheers
