I was wondering if anyone has already had some experience with the Zeiss ZM Biogon 21mm?

Trius said:jvr: Wow, very nice. The colour in the 2nd one is lovely. But there is a serious problem with your R-D1s as shown on the 3rd shot being rotated 90deg. Send me the camera and the Biogon 21, and I'll sort the problem for you; it may take a year or two.

jvr said:Yes, I have one and use it a lot on the RD-1s with a 21-D viewfinder from CV. Great lens. I have other lenses from Leica and CV but the Zeiss is one of my favorites on the RD-1s. The field-of-view is a bit wider on the RD-1s than a 35mm on my M3 (but that's to expect). Vignetting is very good, contrast great, wonderful detail and colour rendering, distorsion very impressive for a full-frame 21.
Would buy it again, no doubt.
Cons: a bit bulky (long) and heavy, not to mention the need for an external VF. But that comes with the territory of a 21.
Lovely image quality.
I post some attachments from a recent trip to Ireland. Epson RD-1s ERF, converted (no colour adjustment), resized and sharpened. I can mail you some "originals", they're too big to post.

"EFR" is the RAW file that the RD1's produce. They can be opened with the Epson PhotoRAW application, or with the proper plug-in with Photoshop. The files can also be opened and processed with Adobe's Lightroom (my preference).
As far as your lens/camera combo is concerned -- Do you have another lens that you could try on your RD1? That way you can determine if the camera does, or does not, have a fault. One thing I have found on my RD1s is that for critical, small aperture shots is to begin my focusing from infinity. This takes any "slop" out of the focus mechanism.
Take care,
Michael
William Hunter said:Thanks Michael, that was a helpful tip. I noticed the lens/body relationship does create "slop." This seems to be what was the issue. The lens does not register on the rangefinder at a distance less than 0.7 meters. Meaning the engineering of the Zeiss lens appears useless on this lens between 0.5 -0.7 meters. By starting at infinity, the focusing mechanism is zeroed to the body of the camera. This must have created those problems, cause I've had some clear shots now 😀
I wonder why there is that no focus zone in the lens that creates the space on the focusing ring of off alignment. That's ironic that it can be corrected as easily as starting from the opposite side of the focusing range at infinity. I'm new to digital rangefinders and they sure are finicky. My first rangefinder was the hasselblad X-pan II which spoiled me. It had such sharp focus...you could keep zooming the scans almost to poster size and still be ok with sharpness. Wish I kept it, I sold it because the Imacon scanner was $9,995. Ouch! I wasn not able to spend that...well I was, I just couldn't touch the money when I had the camera. Did you notice how everything X-pan II has completely dried up for sale? There is nothing X-pan II for sale anyplace, it's all sold out, not even second hand. To think I had the entire kit in my hands last year....🙁
Oh well, digital lets you see what you did the moment you did it...hopefully the X-pan III digital will come out! 🙂
This may be unsettling, and catch you out sometimes on close shots, but it is a normal consequence of using a lens that will focus closer than the rangefinder is able to follow.William Hunter said:I just experimented with the 0.5 - 0.7 meter focusing on my Zeiss 21mm lens. The Epson rangefinder mini window for focusing does not register any focusing changes. It does not move or tell you anything till it hits 0.7 meter. However, it is focusing and changes show in the pictures. This gets confusing because the focusing mechanism you use to check focus remains still in this short range, but the movement effects your pictures.
