The Contax-Canon table lists which Contax C/Y Carl Zeiss lenses will fit Canon dSLRs such as the Canon 50D, Canon 1Ds Mark III, Canon 5D, etc. There is much more data here besides the table below. Browse the sub-menu items for database explanations, additional lens information, adapter information and additional links for more research. This information presented here is intended to help newcomers work their way up the learning curve.

Most people will only need the FF, 5D, 1.3x and 1.6 columns. Scrolling to the right provides more information about the lenses and the final column shows when the data was last updated. There is much information here aside from the table above. Be sure to check out:

2. •Specific Lenses - Additional notes for some of the more stubborn lenses.
   

3. •Adapters - General information on Contax / EOS adapters, including HappyPageHK and Leitax.

THE FF, 5D, 1.3x AND 1.6x COLUMN HEADINGS

1. •FF refers to full-frame dSLRs and includes the Canon 1Ds, 1Ds Mark II and 1Ds Mark III. Note, FF does not include the Canon 5D and Canon 5D Mark II.
   

2. •5D refers to the Canon 5D and Canon 5D Mark II. While full-frame, the Canon 5D and 5D Mark II have their own column because the 5D’s mirror clearance is different than the Canon 1Ds family. For all intents and purposes here, the Canon 5D and 5D Mark II are equal, meaning, if a Leica lens is marked as “N” or “I” for the 5D, then assume the same for the Canon 5D Mark II.
   

3. •1.3x refers to the Canon APS-H bodies with a 1.25x or 1.3x crop factor. This includes the Canon 1D family which consists of the 1D, 1D Mark II, 1D Mark IIn, 1D Mark III and 1D Mark VI.
   

4. •1.6x refers to the APS-C bodies, including the EF mount dSLRs (D30, D60 and 10D) and EF-S bodies (20D, 30D, 40D, 50D, 60D, 7D, 300D, 350D / XT, 400D / XTi, 450D / XSi, 500D / T1i and 550D / T2i).
   

WHAT DO “M”, “S” AND “I” MEAN?

1. •Y means “YES”.  “Yes” means the Contax C/Y lens will work on the respective Canon dSLR and most people have not experienced any problems.
   

2. •N means “NO”.  “NO” means there is no realistic solution for using the lens on Canon dSLRs. Fortunately there are no “flat out no’s” with the Contax lenses; with some experimentation just about every lens will work with every Canon dSLR - except the venerable Canon 5D.
   

3. •I means “iffy”. A lens earns an Iffy rating if some owners say a given lens and Canon combination work, and if other owners say it will not work. Since the answer is unclear and a simple “Yes” and “No” could be misleading, the term Iffy was added.
   

4. •? means no data available. A question mark indicates we have not received any feedback indicating the given lens and body combo does or does not work.
   

5. •Dashes (“-”) mean the data is unavailable - in essence these are missing fields.
   

LEGAL DISCLAIMERS

If you decide to mount a non-EF Canon lens to a Canon EOS camera, you are doing so at your own risk. PebblePlace.com makes no guarantees or warranties - implicit, explicit or otherwise. Use common sense - if something feels wrong --- then stop and examine the adapter, the lens, etc. There may be errors in the table. Be safe and do your own homework too. Using an Canon EOS / Contax adapter is usually trouble-free; however, there are exceptions. Until you know for sure a given lens and adapter combination works correctly with your camera, go slow and pay close attention.
