Guest leicawanabe Posted July 22, 2007 Share #1 Posted July 22, 2007 Advertisement (gone after registration) I just got an email from Ken Hansen who says he has a few Zeiss 16mm hologons which have been converted to M mount with 6 bit code. This should be an interesting thing to play with. Anyway, for those of you who know Ken, you know how to reach him. Link to post Share on other sites More sharing options...

thomi Posted July 22, 2007 Share #2 Posted July 22, 2007 I am interested. How can I reach Ken? Link to post Share on other sites More sharing options...
gwelland Posted July 22, 2007 Share #3 Posted July 22, 2007 Ah yes, a wonderful lens that used to take lots of pictures including my fingers & feet on my Contax G2! It was one of the lenses I regretted selling when I moved out of that film outfit. How much is he asking for the lens with M mount? Link to post Share on other sites More sharing options...
khun_k Posted July 23, 2007 Share #4 Posted July 23, 2007 I have the Hologn modified to M mount already but wonder the cost for 6-bit coding and what EXIF will be showing and what the digital correction will be? Link to post Share on other sites More sharing options...
lars_bergquist Posted July 23, 2007 Share #5 Posted July 23, 2007 I have the Hologn modified to M mount already but wonder the cost for 6-bit coding and what EXIF will be showing and what the digital correction will be? First, the only possible coding so far would be the one for the WATE, pop-up menu and all. Second, the Hologon would be the equivalent of a 20mm lens on the full format, just as the CV 15mm is. Third, I doubt that correct light metering will be possible as the long rear protrusion will mask the sensors. Fourth, when the CV15 was introduced, tests claimed that it was in fact superior to the Hologon even at the 'gon's only f-stop, f:8. It is definitely superior at 5.6 ... Fifth, can you put an IR-cut filter on it? Still, it would be a good conversation piece. The old man from the Age of the Super-Angulon Link to post Share on other sites More sharing options...
audiophileguy Posted August 1, 2007 Share #6 Posted August 1, 2007 Hello all: This post got my attention, as I still own a Zeiss Hologon M mount which I have very much enjoyed using with my M6 / M7 Bodies. I am now almost exclusively using (and loving) my M8, and have not attempted to mount the Hologon because of the severe-sounding warnings in the M8 owners manual about lenses which protrude too far into the body. My question is simple: Who has tried the Hologon on the M8, and what have you discovered about potential damage, problems with metering, and/or any other issues of concern. Thanks in advance for any thoughts on this..... Link to post Share on other sites More sharing options...
Etruscello Posted August 26, 2007 Share #7 Posted August 26, 2007 Advertisement (gone after registration) I had DAG code my 16mm Hologon. (Don Goldberg had done the original conversion from G to M.) He does brilliant work! I asked DAG to paint in the WATE code. I find, when the WATE menu comes up on the M8, that it is best to set the focal length to 21mm, not 16mm, for the fullest correction for cyan corners. (One WATE owner tells him he has to set his menu to 18mm for the 16mm lens position. Apparently, the M8 frimware is still overcorrecting for the WATE -- too much red in the corners.) There is no danger to the shutter with the Hologon's protruding rear lens element. For some exposure situations, you may have to set the shutter manually, as the protruding element does cover the light meter partially. No regrets on the coding. This is a superb lens. My favorite use of it is with B&W and true IR (with dark IR filter). For this purpose, I set lens detection on the M8 to "On" -- not to cyan correction. Tom P.

AGeoJO Posted August 26, 2007 Share #9 Posted August 26, 2007 I contacted Don from DAG last year after I got my M8 since I have one of those from my Contax G days and I knew that he could converted that to an M mount. Due to a lot of uncertainties at that time, including my doubt that I would keep my M8 , I didn't pursue that issue further. About 4-5 months ago somebody mentioned this lens and people raved about it again. But I already bought a CV 15 in the meantime and I am waiting for the 30% WATE..... I remembered this lens being great but not the best of the G lineup. Link to post Share on other sites More sharing options...
brill64 Posted August 26, 2007 Share #10 Posted August 26, 2007 :eek: I would really be very interested to see some examples of your use of this lens with the IR filter I had DAG code my 16mm Hologon.

Stevez4 Posted August 26, 2007 Share #12 Posted August 26, 2007 Having shot with the CV15 and the Hologon I think I can assure you that they are not in the same ballbark. And if you do the same I think you will agree. It's more than about tech charts, Lars. And to be fair the Hologon has a learning curve that the CV lacks.

Etruscello Posted August 28, 2007 Share #13 Posted August 28, 2007 Examples of use of the Hologon 16 with dark IR filter were requested. I've had the filter for it only a short time, so at this time I can share only a test shot from my back yard -- that's the first image. I used split-toning in CS3 for the dual toning effect. I add an IR image from my recent trip to Ireland. I was unable to use the Hologon because it was away being coded by DAG. The second picture, of the Druid Dolmen stone formation in Blarney ( and that's no blarney) was taken with my coded CV15 and Dark IR filter (again with CS3 split toning) for an appropriately eerie look.

Etruscello Posted August 28, 2007 Share #14 Posted August 28, 2007 Sorry -- in my last response I posted the wrong illustration. The 2nd image was meant to be CV15 IR with CS3 split toning, instead I posted the image with its IR cast before B&W conversion and toning. The split toning version is below.
