Canon have replied that the 8-15 is not compatible with their extenders.

I only have cropped sensor bodies - a 7d and an 'old' 40d. The advantage is that the 8-15 is a superior lens to the Tokina, and I don't want to have to carry the Tokina when I've got the Canon, I might even sell it.

Thanks to Ryan for his reply here, and by email offering to upgrade my dome for free. Excellent service.

I've had another go at this and found that actually, the lens WILL work with a Kenko behind it, given decent light on the focus object. The remaining issue is gearing.

As I am shooting on a 7d, I think it will be fine in the DP-100 I bought for the Tokina.

Thanks to all repliers.

I wonder if the different design for the DP100 is for full frame sensor cameras? I've contacted Zen and will report back.

The issue with using extenders is finding gearing rings that let you change the focal length. I use a DP100 with a 20mm Nauticam extension ring when using the Kenko, and Nauti's specially designed gearing ring for that set up.

I tried the 8-15mm lens with a 25mm tube just for fun - no focussed images possible. Likewise a Canon 25mm tube doesn't get anywhere near the 2x II extender because of the cylinder as described above.

It's like Lego for grown-ups!!
