Some great stuff!
Bob -- Terrific color and compositons, and just amazing scenery. I'm probably wrong, but I guess Norway.
morfeus -- Very dramatic portraits -- great use of that 50mm.
fefo -- More great color and compsitions.
Carsten -- Nice shots. Makes me wish I had moist gloomy conditions for green things! I suppose everyone wishes they had some exotic locale shoot.
AhamB -- Thanks for the refresher on that feature of the Canon 1DS bodies. I remember now, reading about that on another forum a few months back (maybe Dec 2010), as I was checking into the "malfunction" of my 1Ds, before I got the 1Ds2. That explains and sorts out the matter of the extension tube. I'll just avoid it, as I have the 100L Macro to get as close as I want.
And, yes, of course! You are completely right about the auto-aperture, as I found out as I continued to experiment and examine the lens, adapter and camera. . .
The saga continues. . .
The other problem was having to do with the lens acting erratic on closing down.
With the lens off the body, with or without the adapter, the aperture opened and closed to all settings just fine, and the auto-aperture lever worked fine when pushed manually.
On-camera, the lens acted up. Sometimes after mounting, it would stay completely open, as though the auto-aperture lever was engaged. Other times (following many attempts at mounting and re-mounting the lens to the body and fiddling with the adapter), the apertures would engage up to f/11, but not 16 or 22. Other times it was erratic exposure, combined with the effects above. And finally, on some tries, everything worked fine, exactly as you would expect an manual aperture lens to behave.
All those gymnastics have lead me to conclude it is likely a coupling problem caused by the adapter. Some clearance or tolerance needs opening or extending. I've sent Fotodiox an email asking all these questions in detail and asking if I should have a replacement or do a simple fix, or if moving to their Professional model might solve things.
Once it gets working on the body, it is gold. It's just that I've been doing a lot of comparisons to other lenses, so every time it comes off, it is a crap-shoot what will happen when I remount it.
On the positive side. . .
This Zeiss/Contax 80-200/4 lens is AWESOME. Yes, I'm shouting because I'm happy and excited.
I'll post a couple shots here for technical examples, but I do have an awful lot I'll want publish and explain -- somewhere.
First of all, without the examples here to show, the lens compared very well against the Canon 100L at normal distances (non-macro), and the Canon is no slouch all the way to infinity. The Canon is sharper, as you'd expect, and has less light fall-off at wider apertures than this 80-200 at f/4-5.6. I'd say that Canon lens ties with my ZE 21/2.8 at the moment for the title of "sharpest lens" in my collection.
Here are a couple close focus shots (not macro) of the 80-200 alone. All shots taken with 1Ds2, from tripod.
80mm, 1/125 @ f/11, ISO 100
200mm, 1/80 @ f/11
100% detail of the 200mm shot above
Here are two shots of a rose showing how nicely the lens handles extreme contrast of the bright white door in the background, and the resistance to flare into the shadow areas and mid-tones. Nice surrounding edges on the deep red rose. Some sharpening and slight exposure correction, but on color correcting or contrast/saturation adjustment. No defringing of colors -- notice the clean lines with the white edge areas.
80mm, 1/640 @ f/11, ISO 100
200mm, 1/800 @ f/11
Finally (for this reply, anyway!), here is an example of off-center sharpness. Focus was on the antenna.
80mm, 1/200 @ f/11, ISO 200
