Carl Zeiss Planar T* 50mm f/1.4 C/Y - Best Overall
The Carl Zeiss Planar T 50mm f/1.4 in C/Y mount is the most-celebrated normal lens of the 1980s era. Six-element double-Gauss design with Zeiss T multi-coating, all-metal barrel, beautifully damped manual focus throw, and a distinctive rendering that combines microcontrast with smooth, character-rich bokeh. Adapted to modern mirrorless, the focus peaking makes manual operation precise.
The trade-off is purple fringing at f/1.4 against high-contrast edges (common to fast vintage glass) and the price has climbed steadily since 2020 as vintage Zeiss became collectible. For portrait, environmental, and low-light work where the Zeiss "look" matters more than autofocus speed, this is the iconic pick. Around $300-500 used in Excellent condition.
Zeiss Distagon T* 28mm f/2.8 - Best Wide Angle
Find at KEH Camera | Adorama Used
The Zeiss Distagon T* 28mm f/2.8 in C/Y is a retrofocus wide-angle with low distortion (under 2 percent barrel), excellent corner sharpness from f/4, and the Zeiss color signature that makes blue skies look saturated without correction. Compact for a Zeiss wide, all-metal construction, click-stop aperture ring.
The trade-off is f/2.8 maximum aperture is slower than modern autofocus 28mm options, and the front element is small so good filter availability requires 55mm filters. For landscape, environmental portrait, and architectural work where wide-angle rendering matters more than speed, the Distagon 28 is the value pick of the Zeiss C/Y line. Around $250-400.
Zeiss Sonnar T* 85mm f/2.8 - Best Portrait
The Zeiss Sonnar T 85mm f/2.8 is a compact short-telephoto with the Sonnar design's characteristic rendering: warm tones, gentle highlight rolloff, and bokeh that is creamy without being harsh. Excellent for portrait work where you want flattering compression without harsh out-of-focus areas. T multi-coated, all-metal.
The trade-off is f/2.8 is slower than the Planar 85mm f/1.4 (which is the more-famous portrait Zeiss but costs $1,200+), so low-light portrait work needs a tripod or higher ISO. For most portrait situations in daylight, the Sonnar 85 f/2.8 delivers the Zeiss look at half the price of the Planar version. Around $400-650.
Yashica ML 50mm f/2 - Best Budget Normal
Find at KEH Camera | Adorama Used
The Yashica ML 50mm f/2 is the budget alternative to the Planar on the same mount. Six-element design (some claim a Zeiss-inspired layout), single-coated rather than T* multi-coated, with softer overall contrast that some prefer for a vintage cinematic look. All-metal construction, smooth focus, click aperture.
The trade-off is lower contrast and more flare under backlight versus the T* Zeiss. The render is genuinely different - not just cheaper. Many cinematographers and Super 8 enthusiasts prefer the ML's softer character for video. For under $120, it is the most affordable way into the C/Y system. Around $50-120 depending on copy.
Tominon 50mm f/1.7 - Best Independent Brand
The Tominon 50mm f/1.7 in C/Y mount is a Tomioka Optical product (the company that made many Cosina and third-party SLR lenses in the era). Six elements, fast f/1.7 aperture, all-metal barrel, and a rendering that splits the difference between Zeiss and Yashica - more contrast than ML, less microcontrast than Planar.
The trade-off is uneven copy-to-copy quality because Tominon production varied; buy from a grader (KEH, B&H Used) rather than uncategorized sources. For shooters wanting f/1.7 speed at under $150, the Tominon is the underrated pick. Around $80-150.
How to choose
Decide between Zeiss rendering or vintage softness. Zeiss T* lenses have higher microcontrast and cleaner color; Yashica ML and Tominon have softer overall contrast that some prefer for video and portrait. Both are valid; the cost difference is significant.
Buy from a grader, not eBay general. KEH, B&H Used, Adorama Used grade lenses with documented standards and accept returns. Vintage Zeiss commonly has issues (haze, balsam separation, oily blades) that a $30 grading saves you from.
Match adapter to body. Sony E, Fujifilm X, Canon RF, and Nikon Z all have C/Y adapters from K&F Concept, Fotodiox, and Urth in the $20-60 range. Cheaper adapters work fine because there are no electronics involved.
Start with one normal lens, then expand. The 50mm Planar or Yashica ML 50/2 is the right first lens because the focal length is forgiving for manual focus and the rendering is most distinctively Zeiss-or-vintage. Add wides and telephotos after deciding you like the system.

Frequently Asked Questions
What does Contax/Yashica mount mean?
Contax/Yashica (C/Y) is a lens mount shared by Contax and Yashica SLR cameras from 1975 to 2005. Zeiss-branded lenses on this mount were made for Contax bodies; Yashica ML and DSB lenses used the same mount as a more affordable alternative. The mount is now adapted to mirrorless cameras (Sony E, Fujifilm X, Canon RF, Nikon Z) with simple manual adapters costing $20 to $60. Adapters are passive (no electronics, manual focus only).
Are Contax/Yashica lenses the same as Contax G or Contax N?
No. Contax/Yashica (C/Y) is the SLR mount discussed here. Contax G is a rangefinder mount used on G1 and G2 cameras with autofocus. Contax N is the autofocus mount used on N1 and NX cameras from 2000-2005. The three mounts are not interchangeable. Adapters and lens characteristics vary significantly between them; this article covers only C/Y SLR mount glass.
Will these lenses autofocus on modern cameras?
No. All Contax/Yashica mount lenses are manual focus only on any modern camera. Mirrorless cameras with focus peaking and magnification make manual focus practical and even enjoyable for portrait, landscape, and street work. For action or wildlife, native autofocus glass is the better choice; for the rendering character that defines vintage Zeiss, manual is fine and arguably part of the experience.
Where do you buy vintage Contax/Yashica glass safely?
KEH Camera, B&H Used, Adorama Used, and MPB grade their used vintage glass on documented scales (Excellent, Bargain, etc.) with return policies of 14-180 days. eBay is cheaper but riskier - check seller feedback above 99 percent and require return policy. Avoid Facebook Marketplace for vintage lenses unless you can inspect in person; haze, fungus, and balsam separation are common and not always disclosed by amateur sellers.
Are Zeiss T* coatings still worth the premium?
Yes for most users. The T* multi-coating reduces flare, increases contrast, and improves color saturation compared to single-coated equivalents. Side-by-side, Zeiss T* lenses show measurably less veiling flare against backlit subjects. Yashica ML lenses are single-coated and have slightly lower contrast straight out of camera, which some shooters actually prefer for a softer vintage look. The right answer depends on whether you want the cleaner Zeiss look or the dreamier Yashica rendering.
