SMC Pentax-L 43mm f1.9 Special apo No mechanical or electronic coupling:

No mechanical or electronic coupling: this is a fully manual tube

PLEASE NOTE: This teleconverter is for the Four Thirds digital SLR system

The Asahi Super-Takumar 35mm f2 is a wide-normal lens for M42 mount with a nice classic character

not  in the general sense (it's still just shy of 4kg with the integrated three-way head

and Leica went back to the black material as soon as the shall-we-say regrettable situation was resolved

SMC Pentax-L 43mm f1.9 Special apo No mechanical or electronic coupling:Yes, Pentax did make Leica thread mount lenses! That is to say, they made one specific model (this one) and only 2000 in total. But it's a great lens, with a useful normal wide focal length, a fast f1. 9 aperture, and excellent imaging. It's a Leica thread mount lens, but it's compatible with any M mount camera using the included adapter. This example has light paint and finish wear, clean glass, good function.
