DA* 300 Question

Can anyone who owns the DA*300 give me the width of the opening at the flange and the depth from the flange mating surface to the rear (interior) element? I need to know if the opening is >33mm and the depth >17mm, but don't have my own lens handy to measure (I'm out of the country at the moment).

Thanks for the help.

Here are pics of the flange of a DA*300mm. I am not sure exactly where to measure what you want. If you can somehow copy and mark the pics to indicate what you need measured i will be delighted to help you.

The opening is about 35.5mm. The distance from the flange mating surface to the rear element is less than 10mm. I cannot get an exact measurement because I do not want to touch the rear element (of course).
