Contax / Yashica Yashica ML 70-210mm f4.5 Heritage

เรื่องราวของเลนส์

The lens named in this request appears to conflate two distinct Yashica products documented in the sources. There is a Yashica AF 70-210mm f/4.5 (an autofocus telephoto zoom for the Yashica AF mount, not the C/Y mount) and a Yashica ML 70-210mm f/4 (a manual-focus C/Y-mount zoom). No source documents a 'Yashica ML 70-210mm f4.5' in the Contax/Yashica mount specifically; the f/4.5 model is the AF version, while the C/Y ML zoom is the f/4. Given the requested C/Y mount, the closest documented match is the Yashica ML 70-210mm f/4, one of the rarest and most revered ML zooms. According to an owner review, it was produced only briefly (1979-1980), replacing the 80-200 f/4 for less than a year before production was abandoned in favor of the lighter, smaller and much cheaper 80-200 f/4. As far as is known only a few hundred were made, and it was the most expensive lens in the Yashica range other than the ML 1000mm f/11, making it something of a collector's grail. The owner speculates it was built at the Tomioka factory, the same facility Yashica used to build Zeiss lenses and the best ML glass, noting it feels very like the Zeiss 70-210 f/3.5 Vario-Sonnar minus the Zeiss lens's macro facility. No established nicknames or community jargon (e.g. 'Bokeh Monster') are evidenced in the sources for this lens. Its cult following stems from its extreme rarity, superb build quality, and its perceived kinship with the Tomioka-built Zeiss zooms.

สรุป: If you specifically want a C/Y-mount telephoto zoom, the documented lens is the Yashica ML 70-210mm f/4 — a rare, superbly built, Tomioka-pedigree collector's piece that owners rank among the best of the ML line, though it is heavy and extremely hard to find. If you actually mean an f/4.5 lens, note that this designation belongs to the autofocus Yashica AF 70-210mm f/4.5, which is a different, far cheaper lens for the Yashica AF mount, praised for nice wide-open bokeh and excellent sharpness in portraiture. Verify mount and aperture before buying.

รีวิวจากผู้ใช้

ข้อดี

Amazing build quality; described as feeling very like the Zeiss 70-210 f/3.5 Vario-Sonnar (mechanical quality rated 5.00)
One-touch (push-pull) zoom design with no zoom slip at all despite the massive amount of glass
You zoom out for closer focusing, integrating focus and zoom behavior
Extreme rarity and prestige as one of the rarest and best of Yashica's ML lenses
Presumed Tomioka-factory pedigree, the same source as Yashica-built Zeiss lenses
High overall optical quality rating (5.00) from owners

ข้อเสีย

Very rare and hard to find, so pricing is near impossible to establish (owner priced value at 3.00)
Heavy (1000 g) and large compared to the lighter, cheaper 80-200 f/4 that replaced it
Lacks the remarkable macro facility of its Zeiss 70-210 Vario-Sonnar cousin

เทคนิคการใช้

For the C/Y ML zoom, zoom outward to achieve closer focusing per its integrated one-touch design
Owners rate it excellent for optical quality and bokeh, making it well suited to portraiture and telephoto work; shoot wide open to exploit its rendering (the related AF 70-210 gave 'nice bokeh wide open')
Handle and store carefully — with only a few hundred made, replacements are effectively unobtainable
