[turbo_pascale (Rob)]

I have the the oldest type of WO reducer... quite a chunky number.
When I first configured it, I opened up the camera, flipped up the mirror and measured to the front of the t-ring. It was pretty close to 50mm from memory (which is apparently what it is supposed to be, but I can't find any official specs), and I just assumed the discrepancy was my measurement inaccuracy.

I'll have to re-measure everything, and see if I can spot the difference, and hope that adding a spacer (rather than having to move it in!) is an option.

To be honest, I'm a bit frustrated. When I didn't have the flattener, I never had the elongated stars in the corners (well, it wasn't obvious). -- Just went back to check older images - it was there, just not as obvious because of the choice of image. If anyone else has the same reducer, please let me know how it goes for you.
