A crisp clear lens with really excellent optical quality. However the autofocus is a bit lost with this lens, and the screw drive is sloooooow.
Excellent results in astrophotography

Hi Folks,
Just a precision about the versions. The "Zebra" optical version has nothig to compare with the MC version. The MC version is closer to the Meyer-Optik Orestegonn 300mm than the original zebra design. This was done essentially for cost reasons because the original zebra was very difficult and expensive to manufacture.
As a consequence the chromatic performance of the later MC versions is much lower thant the older ones (zebra type). You can find some comparisons here : https://zeissikonveb.de/start/objektive/objektivtests.html
The chromatism is reduced on MC types when it is stopped down. | |
