Up for sale is a CLAed and PENTAX PK converted sample of the rare classic Yashica ML 24mm f/2.8 Super Wide Angle lens.
Designedesigned for Contax and Yashica film cameras during the period when Yashica was producing both their own and Zeiss-branded-lenses, this lens comes from their top-end "ML" series.
This lens originally featured a C/Y bayonet mount, which has been replaced with a genuine Pentax PK mount removed from a Pentax M series lens. As a result, it is usable on ALL Pentax K mount cameras, from the earliest K series film cameras through the latest Film DSLRs such as the KP and K1mk2. In addition, it can be mounted with an inexpensive adapter on a variety of formats, including Canon E F and Mirrorless, m4/3, Sony E (A7), Fuji, Nikon, etc.
The lens functions like an m42 in manual mode, meaning the blades stop down as the aperture ring is turned, making it easiest to use in either green button or "A" modes on Pentax DSLR.
While Disassembled, this lens was also CLAed (Clean/Lube/Adjust) with full removal of original lubricant and replacement with modern grease for increased smoothness!
CLA FAQ:
Q: What services do you perform
on the lens before sale?
With
the lens disassembled, I perform a
full CLA (Clean Lube Adjust). This entails cleaning out any internal
and external soiling, cleaning aperture blades of grease that can
slowing, re-lubing the focus helical (even seemingly fine "mint" vintage
lenses typically have grit and degraded grease in their helicals), and
adjusting all
components for tightness and accuracy. Where there is extensive dust
or internal lens soiling, I will disassemble lens cells and clean off
surfaces; however, it is my general philosophy to keep lens elements
in their factory position when at all possible to ensure optimum
performance.
Q: DUST? What do you mean DUST?
A: All
vintage lenses have dust in them. In fact, they had dust in them when
they were brand new from the factory! This is because prior to
the advent of very modern sealed designs, lenses were not put
together in a clean room environment, and the natural static charge
of the glass tends to attract dust particles. Coupled with the open
designs used in these lenses, it is virtually impossible to find any
vintage lens without some degree of dust particles visible when you
look closely through the lens. All of my CLA lenses have at minimum the
exterior internal cell surfaces wiped with a dust-free, lab-grade
optical tissue and then blown off with an air bulb prior to
reassembly and thus have a significantly below average amount of dust for a vintage
lens.
Includes original Front Cap and m42 rear cap.
