Originally posted by solaris I am also wondering about the sharpness of your lens. My lens actually seems to be sharpest wide open, at 3.5.
Umm, does it close down beyond f3.5?
I have to admit that since it performs so well wide open, and the bokeh is so good, I tend to keep it on f3.5.
Quote: Georg, does your Sonnar have the red MC? I've seen some other photos of Zeiss lenses that have a very strong red reflection when you hold them up to a lightbulb. I remember seeing it on some 28 or 35mm lenses, but not sure if I've seen one on a longer focal length.
My Sonnar is red MC and it has a very distinct red reflection. My Flektogon 35/2.4 has a bluish reflection from the front element but when I tilt it, I can see a more purpleish reflection from a lens near the diaphragm.
Talking of the Flektogon, this was taken today at f5.6:

The Flektogon is very good at greens.
As to the Sonnar, well the colours generally are good. The following have been taken straight from the PEFs with just some cropping. (Plastic pegs are good for colour tests <g>). I think the railway bridge was taken with a polariser.
I cannot remember exactly (I took the photos of the pegs over a year ago), but looking at the size of the pegs I must have used an extension tube. I've only cropped slightly for better composition.
I think you'll agree that the colours are very good.
