YASHICA ML 28mm f2.8 Contax/Yashica C/Y mount Made in Japan

In good working condition for the age.

Scratch and fungus free optics (minimal dust). 

Smooth (vintage smooth) focus and aperture.

Very good, used cosmetic state.

The lens comes with:

Back and front random caps.

Unedited samples shot on Canon 600D, hand held at ISO 100/200/400, use of hood highly recommended.

One of those lenses in no need for any additional recommendations, beautifully constructed, reliable companion anytime, anywhere.

Yashica's ML lenses were manufactured at the same time as the Carl Zeiss AE T* lenses under the licence. 

The Zeiss glass was made at the Tomioka Kogaku plant, bought by Yashica in 1968 but I don't have any information to what extend Tomioka was involved in production of ML design, possibly optical elements/coating only, unfortunately the exact details will forever be a mystery. 

ML stands for “multi-layered” coating and the series was designed to fill the gap between Yashica's own consumer-grade DSB lens line and the state-of-the-art Zeiss T*.

The ML series was produced until 1985 and earned over the years a reputation for high quality.

The above copy is very reliable and easy to handle despite being quite heavy. 

I was impressed by the quality of ML coating, which I am somehow sure was inspired partially by the almighty Zeiss T* formula at least on the “not totally secret” level. 

The colour rendering is nicely balanced with adequate amount of contrast and good optical accurateness. 

Relatively fast focusing indicates good potential for street photography or similar quick changing environments.

Not shy of close ups too.

Please mind, the above short review is subjective (I like to read online reviews too, but nothing is more accurate and unbiased than own test shots), based on my few year experience with vintage prime lenses and relate only to this particular lens, as quality may vary, tested on 18MP Canon 600D camera plus my personal skills as a photographer, the test samples are large JPEG (probably compressed by eBay automated system), you have a two weeks return option to try it yourself.

I do have a habit to test and look for any faults so they're exaggerated in the listing for you to avoid unnecessary disappointments, any relevant questions are also welcome.
