Cutting Ikelite 6" Dome Shade...

[kbrembo]

I just recieved my Tokina 10-17.5mm FE

The edges of the Ikelite 6"dome shade is in the picture from 10-13/14mm

Any one cut the shade and how much?

Cheers

Sounds like a lot of work. Why not just take the shade of altogether?

Hi Keith:

Can you send a link to an example? I am thinking that you need a shorter extension ring. I have the same lens on a D70s with a Subal housing, and it is fantastic. The only problem is that the field is so wide it is easy to pick up shades, corners of ports, and parts of cages on shark dives if the extension ring is not the proper length.

Good luck!

Has anyone done this 6" dome shade modification on the Ikelite for a Tokina 10-17 ? can you give a description (how much did you need to take off/where). A picture would be fantastic.

Thanks for any help,

I shoot a nikon D-50 in an Ike housing with a 10-17 Tokina and remove the sunshade on the port.It is just three screws that need to be removed on the port sunshade.Why cut it down when you can just remove and replace?

Just wondering... I just picked up a Tokina 10-17 too but I am using the 8" dome port (not the 6") . Does anyone know if the 10-17 is going to pick up the dome shade on the 8" port?
I am using an Ikelite housing with the recommended extension ring for the Tokina 10-17.
Thanks

Keith,

Yes on Nikon dSLR cameras with the 1.5X sensor crop you will see the shade corners of the Ikelite 6" port until as you state. When your Tokina 10-17mm is zoomed to about 13mm it will disappear. With Canon dSLR cameras (as I shoot and have a 1.6X crop) it disappears at about 11mm.

Best advice for possible solutions are:

* Live with it and crop in post processing.

* Zoom to 13mm which is still pretty darned wide as the Tokina 10-17mm is a Fisheye and doesn't follow the exact 1.5X times focal length rule. (Actually appears a bit wider than a rectilinear lens at all focal lengths.)

* Take the shade off.

A fellow Canon shooter cut his shade up and even with the extra crop of 1.6X he needed to really scallop out the circles before any vignetting was gone. When I use a 6" dome I just zoom in a bit and live with it. In fact, with the 6" port I think the Tokina 10-17mm Fisheye lens is SHARPER at 12-13mm at the widest due to the smaller dome compared to an 8" port.

Another Ikelite Nikon customer of mine simply took his 6" dome shade off.

Anyone using the 8" dome with recommended extension and a Tokina 10-17mm Fisheye lens will not see shade vignetting.

Hope this helps!
