In Topic: Tokina 10-17 FE + 1.4x TC in 100 mm mini-dome

03 July 2016 - 11:02 AM

Now I finally bought all the parts (Kenko 1.4x, zoom ring and 28.5mm extension ring (Aquatica #18453)) and there is something that isn't right.

When I try to set the zoom to the long end, the lens (actually the "hood" that is a part of the lens) hits the dome glass before the lens reach full length.

The 28.5mm extension ring is too short.

Has anyone else experienced something similar?

Jean?

Hi Stewart.

When you say "isn't bright enough to aim with", do you mean that the light can't be seen in the viewfinder whatsoever, or do you mean it's too weak for the camera to fucus on?

Good point there. I will make a simple prototype to test the concept before making the final version.

I have been considering doing something similar for a YS-D1, but with the addition of focus light.

 

Most people find it difficult to get the snoot-light at the right place and it often takes many iterations before the light is right at your focus point.

 

My idea is to put some of the fibers in front of the strobe’s LED light instead of in front or the flash tube. If there is some continuous light coming out from the fiber snoot, it would be much easier to aim the light. Both the YS-D1 and the z240 have excellent lights for this purpose.

 

Do you think this is feasible? I don’t have any experience in working with optical fibers like this.
