Zeiss 85/2.8 vs. Zeiss 85/1.4

Hi Rick,
I've never tried the 2.8 but for reasons I won't bore you with I currently have two German-made 1.4 AEs in my possession. Optically there is very little to choose between the two ex&les, both of which are fairly well-used (I picked up the more expensive of the two for 300 GBP).
Both of them are extremely sharp beyond f/4, and give very good bokeh. However, I was shocked by the performance up to f/2, as both lenses are soft to say the least. A Canon 85/1.8 EF is appreciably sharper at f/2, for ex&le. I can post cropped test shots at f/8 and f/1.4 if you want to see what I'm on about, but all this is in accordance with the MTF results on photodo.com (which I didn't make the effort to fully understand before setting out to buy).
However, I've got no regrets about the 1.4 because if you stop it down a little it is definitely one of the world's sharpest lenses. Even at wide apertures it is still valuable, because the soft-focus effect it produces can be used to good effect, but don't expect sharpness at those apertures or you'll be disappointed.

Right, here goes. Here is a low-res JPEG of the whole frame, plus some centre-frame detail at 100% in a TIFF file. These shots were taken on Pan F+ and scanned at 2700ppi on a Nikon LS-30. No sharpening has been applied, the scans were done in RGB and then converted to greyscale just by changing the image type in PS7. At this distance at f/1.4 the DoF is very shallow, so I have chosen a detail that extends a short way along the lens axis, to guarantee that some part of it will be in the plane of sharpest focus. The stitching on the strap should give a pretty clear idea about the fine resolving power of this lens at both apertures.

Here are two more detail areas, of the canvas of the right-hand shoe, so you can get a rough idea of edge sharpness.

Finally, here is a portrait taken at full aperture. Unfortunately this board's restrictions on image size mean that you can only get a rough feel for the soft focus effect provided by this lens wide-open, but it's better than nothing:

(Under IE6 at least, when you download the TIF files in the two messages above they will be saved by default as .UNK files for some reason. Simply rename them back to .TIF and they should open fine.)

This thread is a rather timely one as I too have been considering the 85mm focal length. As much as I would like to get the 85/1.4 my budget does not stretch to it. Knowing that I like the results from my Rollei 35SE I have been considering the 85/2.8 Sonnar. The only problem is that I can not find a used one. My question is why is this lense so hard to find used? I keep on scanning keh.com and nothing comes up.
