I have done some shot test for both lens before, separately,

I have unfinished homework in CZJ 135/3.5 review above that is to test the lens sharpness once again because I doubted its sharpness, especially compared to the Olympus.

This afternoon I got time to take couple of shots from both lens and here is the results.

I was using 5DII with Standard picture style on its default setting.
All lens at wide open aperture.

CZJ 135/3.5




Olympus 135/3.5




100% crop - focus was not in the same plane & the exposure is bit off on Oly

By the way we could also see the bokeh comparison of both lenses Smile

In terms of pure resolution, there is hardly any difference or they are hidden in slight focus point differences. Unfortunately, on the leaf crops, Oly shows stronger CA. Sonnar for me Wink

Yap Smile Finally I could remove my doubt about CZJ sharpness Smile
But still I want to try the MC versus the old silver 135/4 though ... haha Smile

From above comparison, both sharp in the center. CZJ looks sharper in the corner.
The bokeh looks not much different.
CZJ has lower CA than Oly.
But overall both are great lens Smile

The CZJ clearly shows why it is so highly regarded. No competition here.
