3. It has 2 (not dot) for the F/2.
4 It has the yellow tint.

IR mark left of the f/4 mark and flat rear element. The 8 element has the IR mark to the right of the f/4 mark and a curved rear element.

7 Element.
.
IR indicator mark should be between 4 and the diamond, the rear element should protrude more with less metal near the top.
Also I think I may be able to find a link that shows that the serial number is not consistent and the numbers on the AUTO/MANUAL switch may also be inconsistent with the 8 element version. The A/M vs. Auto/Manual is shown to be non-deterministic by a number of sites.

An old thread that gives more details...

Consistent with what I said the Part Number given on the A/M Switch is not the one expected on the 8 element version.

OK thank you for the answers.
I am waiting for an M42-NEX-7 adapter to start taking some pictures with it.
