Advertisement Posted January 24, 2014 Posted January 24, 2014 Hi bephoto, Take a look here Is there anybody out there... with a Hologon 16 and Leica M 240?. I'm sure you'll find what you were looking for!
wlaidlaw Posted January 24, 2014 Share #2 Posted January 24, 2014 Is there anybody out there... with a Hologon 16 and Leica M 240? does it work or still has the color cast problem? Don’t you mean a Hologon 15mm, which is the one for Leica. The Hologon 16 was made for Contax G. Of course you can get these converted by Dirk Rösler at Japan Exposures and this is easier than most as no need to RF couple. I had one for my Contax G and to be frank, it is more trouble than it is worth (especially considering how much money I got for it when I sold it). You really have to use a radially graduated ND filter to counter the extreme vignetting and it’s very slow at f8. If you have to have a 15mm lens, I would say that the Voigtlander 15/f4.5 Super Wide Heliar is a better and much cheaper alternative, although I have found you have to set up a correction profile to cure red edges on the M240 (it’s fine on the M9). The proper solution for a 15mm lens is either one of the R lenses, Elmar or Elmarit or the Zeiss Distagon ZM, which is an RF coupled but retrofocal lens. There is not a lot of different between the price of the Distagon and Elmar but the Elmarit is rarer and more expensive. Wilson Link to post Share on other sites More sharing options...
thighslapper Posted January 24, 2014 Share #3 Posted January 24, 2014 The voigtlander 12/5.6 also works very well and if coded as 21/2.8 has very acceptable vignetting and no peripheral colour cast in all but a very small percentage of images and I've yet to find one where it was noticeable enough to process out ... The Voigts are not that expensive and excellent for the money .... RF coupled and in M mount...... Daft to get anything else unless you only have peanuts to spend ......

Leicaiste Posted January 25, 2014 Share #4 Posted January 25, 2014 Is there anybody out there... with a Hologon 16 and Leica M 240? does it work or still has the color cast problem? I tried the Hologon 15mm + graduated filter on the M240 (coded as a 16mm WATE). Yes. There was a colour cast problem. Welcome, dear visitor!

The Voigts are not that expensive and excellent for the money .... RF coupled and in M mount...... Daft to get anything else unless you only have peanuts to spend ...... There is obviously quite a bit of sample variation either from lens to lens or body to body. I have my CV 15/4.5 coded as a 21/2.8 and it has quite noticeable red edge, visible in just about every image. I became so bored with picking out every image taken with it and applying a correction profile layer plus I don’t think resolution is good enough for the M240, that I have bought an SEM 18 to use instead. I would imagine that the 12mm lens would cause even worse red edges than the CV15 but there may be an odd quirk working here. Wilson Link to post Share on other sites More sharing options...

Wilson The CV 12 behaves quite differently than the CV 15, and has much less vignetting and no noticeable magenta edge when coded as a 21 pre-ASPH. These two CV lenses are definitely not the same.

thighslapper Posted January 25, 2014 Share #8 Posted January 25, 2014 you've got Steve instead of Stephen works surprisingly well .... sharp, moderately contrasty and very neutral colour-wise ..... a delight to use with the M+EVF. produces some nice images but the effect can be a bit over-pwering unless used sparingly ..... santa brought me one for xmas ...

wlaidlaw Posted January 25, 2014 Share #9 Posted January 25, 2014 You are getting slightly pink LH corners with your CV12 but it is nothing like as bad as the CV 15. I wonder why that is? If you look at the lens diagrams, the 12 and 15 are both basically heavily modified Gauss Doublets and apart from the two extra corrective elements to allow for the greater curvatures in the front and rear groups of the 12mm, quite similar in design. It is not as if the 12 was a retrofocal design, like Zeiss and Leica use for their 15 and 18 mm RF lenses. Wilson Link to post Share on other sites More sharing options...
brill64 Posted January 25, 2014 Share #10 Posted January 25, 2014 ...to answer your original question, there are not that many m-240 owners out there with a Hologon. If there were, it would be tucked away neatly in a dust-free, humidity controlled glass cabinet & forgotten about as this is now a collectors item & an expensive one at that!. A very cool looking & unusual lens that starts at f8. For practical use, it's better suited to a film M. Link to post Share on other sites More sharing options...
01af Posted January 25, 2014 Share #11 Posted January 25, 2014 I tried the Hologon 15 mm + graduated filter on the M (Typ 240), coded as a 16 mm WATE. A code for 16 mm WATE doesn't exist in the first place—it's always 21 mm WATE. And this basically is the worst code among all wide-angle M lenses. Better use the code for the Elmarit-M 21 mm.

StephenPatterson Posted January 25, 2014 Share #12 Posted January 25, 2014 Stephen - Do you have the CV 12 and if so, what do you make of it on the M? Rick As Steve pointed out with his excellent examples there is a huge difference between the CV12 & CV15 on the M240 when coded as a 21/2.8 Pre-ASPH (11134). While the CV15 will still gives magenta edge it is almost entirely corrected with the CV12, making this lens imminently useable without the need for Cornerfix or a flat field correction.

plewislambert Posted January 31, 2014 Share #16 Posted January 31, 2014 "The CV 12 behaves quite differently than the CV 15," This applies also to the 12mm on the M9, where it performs well and so I sold my CV 15mm. I still carry a 17mm Tokina, which works well at f5.6 or f8, no colour fringing. Philip:) Link to post Share on other sites More sharing options...
helged Posted February 3, 2014 Share #17 Posted February 3, 2014 A very cool looking & unusual lens that starts ...and ends... at f8. For practical use, it's better suited to a film M. or M Monochrom... I have a version that is coded as Elmarit-M f2.8/21mm. The (mis)colouring, with and without the 4-stop central filter is illustrated below, taken with a M240. Please focus on the main patterns; it's limited daylight in Norway at this time of the day/year, so I simply used some available, not-too-even artificial light on a whitish wall. And yes, Cornerfix removes most of the colouring and fall-off. It's an intricate lens for digital colour captures, but works well for b&w. And it's so small that it almost approaches the territory of MS Super Triplet Perar 28 and 35 mm... Welcome, dear visitor!
