HI everyone!

 

New to the Forum I take my opportunity to solve my "Problem":

 

My rig is the nauticam-housing for the Canon 550D and the "insect eye port" C60M130 for the Canon 60mm macrolens.

 

Now I like to use this port with the Canon 100mm macro USM (non L, non-IS).

 

So the question is:

 

which portextension (length) do I need for this Combo and the same question when I like to use the 100mm with the kenko 1,4 teleplus 300 DGX - convertor?

 

The port-Charts at the nauticam-hp do not show this Combo, but I'm sure they will work - just with which port-extensions???

 

I hope sombody can help...

 

Best regards, Tom

50mm will be a touch long, but will accommodate the combo.

Hi Ryan,

 

I tryed the 40mm plus 20 mm and this is quite a little bit too short, because the insect-port inside isn't that long as it looks like....

 

Any advice is appreciated for my two "problems".... Did anyone try these two combos??

 

Greets, Tom

Hi Tom, I just double checked, and the #18721 insect eye port I have definitely works with the 50mm extension, with room to spare (I actually put the combo together).

 

Are you sure this is the lens you are trying?

There is an older Canon 100 that isn't USM, and isn't internally focusing, and is longer.

Hi Ryan,

 

confusion solved !

 

The lens is the same you mentioned; 50mm are perfect!!! And the TK is 20mm so for this Combo 70mm are enough.

 

Thanks for your Input!! :dancing:
