Originally posted by OzzRod I hope you're right, but you might find this old thread useful. It contains lots of contradictions but the favoured identifier seems to be having the red IR marker located between the red diamond and the f4 marker.
I stand corrected. This is most likely the 7-element version by serial number (barely!); by the location of the IR marker; and by the part number printed on the back side of the stop-down switch. The latest known 8-element has a serial number of 1650141, according to
this page.
It does, however, have a protruding rear element at infinity focus, which is supposed to be a sign of the 8-element, as well as A/M markings near the stop-down switch, rather than AUTO/MANUAL...but I think this is just wishful thinking on my part. Thoughts, anyone, from someone more experienced than me on this? I can post pictures if anyone is interested.
Ah well - still a worthy lens, and I paid about market price ($60 USD). I'll call that a win.
Still going to be my August lens.
