My commentary on the above crops:
In general, I still prefer the rich colors my images have through the Contax 100-300 glass. It’s subjective, but to me, color and micro-contrast is the Zeiss’ strength. The Contax does not seem to improve when stopping down in any area of the frame, performing best wide-open at all focal lengths. That's surprising.
Resolution and contrast are similar but I can easily see higher resolution and micro-contrast in most Contax 1:1 crops up to 200mm. At 300mm, the advantage goes to the GM, especially at mid and corner areas. It’s not a big difference but it’s there at 1:1.
Here is what I see. Let me know if you agree with me:
@ 100mm f/4.5:
The Zeiss is noticeably better at center. At mid-field they are very similar and the Zeiss zoom takes the lead towards the corners again.
@ 100mm f/5.6:
The GM zoom improves at center but I’d still give a small lead to the Zeiss. At mid field, they remain similar and the edges go to Zeiss, although the GM improved greatly from wide-open.
@ 100mm f/8:
The Zeiss still slightly better at center but at mid-zone and edges, they are very similar now.
@ 200mm f/5.6:
Similar at center, perhaps GM very slightly better. At mid-field, the Zeiss does slightly better but at the edges, the Zeiss wins big. Note: My GM zoom is NOT decentered at 200mm. All corners look very similar.
@ 200mm f/8:
The Zeiss zoom is slightly better at center and mid-field and considerably better towards the edges.
@ 300mm f/5.6:
I can see that the Contax does very slightly better at center. At mid-field, the GM jumps ahead and at the edges, it's still better.
@ 300mm f/8:
Similar at center, mid-field and edges! I would still give the edge to the GM for mid and edges.
@ 400mm f/5.6 vs f/8 for the 100-400 GM:
There is a nice improvement everywhere in the frame for the GM going from wide-open to f/6.3 and f/8 (shown here)
