Thanks. I'm glad to hear it because it was kind of an impulse buy.
I like it though so I am happy I bought it. |

The Tamron 28mm F2.8 is a great lens. At F5.6 the image quality is uniformly good, corner to corner, even in FF.
The Tamron is better than Pentacon 29mm F2.8 with the exception of resistance to flaring and ghosting, when the Pentacon is better.
To give an idea, the Tamron 28mm f2.8 wide open is as sharp as the Helios 44M-4 at the same opening F2.8.
The only problem I noticed in theTamron is a high sensitivity to decentering. Just change the tightness of the retaining rear of the back optical group for some decentering appears. _________________ If raindrops were perfect lenses, the rainbow did not exist. |

I would say that both lenses have the same DNA. The Tamron 02B is the successor to the CW-28. The optical diagrams are very similar (7 elements - 7 groups), but the individual lenses are different.
The CW-28 is considerably heavier. The 02B is slightly faster, F2.5 versus F2.8. The CW28 has a switch to change the diaphragm control from automatic to manual.
Tamron says that CW-28 is multicoated, but as is usual in almost all lenses, some optical surfaces are left single coated. I believe that 02B has more multicoated surfaces than the CW-28 because the 02B is a newer design.
I cannot tell about differences of performance because I only tested the CW-28. I suspect they perform very similarly.
I forgot to say in my previous post that the color rendering of the CW-28 is much cooler than the Pentacon 29mm F2.8. _________________ If raindrops were perfect lenses, the rainbow did not exist. |

Looking at both lenses.....If it means anything the rear lens on the F2.5 has a larger diameter. _________________ Canon A1, AV1, T70 & T90, EOS 300 and EOS300v, Chinon CE and CP-7M.

This is the early Adaptall I think, which seems to be the same as the later compact version of the Adaptamatic.
Quite a decent lens on APS-C.
