I have the panel ordered together with the above objective, just so I have all the same completely. When unpacking then I noticed that the Tamron has just has a screen with it.
One can save the purchase of this diaphragm so first.
So technically would be 5 star correct, but because at the Tamron is not there, that a diaphragm with here is, I think that it is justified to subtract a star.
Important to me is that the reader can save the output of this aperture. Sure, you can return at Amazon. However, for the purchase price minus shipping and so it is hardly worthwhile to queue at the post office in a long queue.
