Hi all

I am thinking to buy a hologon 16mm for my leica M9.

is CornerFix working for hologon color shifting problem on m9?

 

or any other software can fix hologon color shifting problem?

 

I know vc 15mm works. just love hologon more. i don;t mind use software to correct it.

 

anyone got hologon on M9,? please help to take CornerFix profile blank white image (send to my email er.li.mi@gmail.com ). so i can work on a fixing algorithm, I am software engineer.

Eric, welcome to the forum!

 

I have neither Hologon 16 nor M9, but I'm a firm believer in CornerFix.

 

It'll work with any camera you want to throw at it. And if you want to super-massage your files, Sandy has given it enough bells & whistles to satisfy. :)

Are you referring to the Zeiss/for Leica 15mm Hologon? That is a rare collector's piece. Also, the lens protrudes so far into the camera that light must strike the sensor at a very flat angle. It is doubtful that there will even be a meaningful image to correct. Also, the meter cell will be blocked, so no in-camera metering.

the new 16 hologon, converted to leica m.

I don't mind the meter, as i am doing mainly architecture, which i have enough time to get the right exposure

 

the only thing i am worry about is that color shifting. if it is too heavy and complex, it may not able to be corrected by CornerFix

yes, you are right. G 16mm hologon. which can be convert to Leica M

 

Hi Eric,

Are you currently the high bidder on my auction for that lens :D? How coincidence if you are. Yes, it can be converted into a Leica-M mount and since it is a manual focus lens, it is simpler to do than the other Contax G lenses and it is an ultra wide angle lens that will give you plenty of depth of field, you can zone focus it without the need of RF coupling. I have seen images of this lens on M9 and they look impressive but I don't want to be biased. So, feel free to "google" it and look at them yourself.

Let me add something to the images I saw. There is a high degree of vignetting and as such, the color shift was not apparent. I don't know what to tell you in that respect. I am not sure whether the shooter used the "anti-vignetting" filter or not, but judging from the amount, I would say probably he did not. The advantage of the Hologon is that the distortion is kept at minimum, which is a desired characteristic for an architectural lens. I am sure you are aware of that. Again, I am not trying to convince you to buy the lens, BTW. It is entirely your call, of course.

 

I did talk to Don Goldberg of DAG when I bought an M8 regarding the conversion. Don is a well respected Leica repair specialist here in the US. Yes, he offers that service and he quoted me between $300-400. But that was a few years back and I am not sure about the current status to be honest. At that time, I had the chance to buy a WATE through the special program from Leica when the M8 was recalled and I decided not to do the conversion.

yes, it is me. nice to see you here. G2 is almost the same price as conversion but I do need both digital and film, in that case, I have to convert it to leica M mount.

 

focus is never a issue with ultra wide. I was using hassy SWC. never have problem with focusing. so i am not worry about that.

 

hologon works better on M8. as most edge has been croped off. but on M9, vignetting is so heavy that i can't avoid it. I have to use that filter all the time. and you are right, without the filter, image is too dark to see the color shifting at the corner. that is why it looks ok.

 

I am sure Leica engineer can fix the color shifting issue with firmware upgrade. the only question is that are they going to work on it for less than 350~500 hologon 8/15 user? so I am not waiting for their them. I prefer just use CornerFix if it works.

 

 

So i need a help from someone has a converted hologon and M9, send me a profile image, so i can test with CornerFix. even CornerFix is not working. I am software engineer and I can work out myself.

 

 

help !!!!! please. anyone know who have a converted hologon and M9

Here is a quick shot with a 15mm Heliar-M. I used Capture One to get out the color cast which wasn't too bad on this shot. Shooting the white LCC plate isn't that tough takes less time than opening a 35mm cassette when you have to develop film! I was close to getting the 18mm Leica, but I think this will do it for me. What surprised me is how well the clarity and sharpness holds up in the corners. A lens bargain with snappy results.

I believe Corner Fix can handle any wide angle distortion, though it does not increase the lens' edge to edge resolving ability

I have both the CV Heliar & CZ Distagon & Corner Fix handles their files flawlessly

be certain to carefully follow the directions, particularly on how to expose for your profile images

I went to the extreme of shooting separate profiles at different capture ISO settings, though I don't think this necessary :mad:

both Lightroom & Capture 1 can fix these problems as well & I use them much more often primarily for workflow reasons, but my experience with Corner Fix suggests that it works at least as well

coding these lenses as the 16 mm WATE helps enormously and every effort should be made to set the camera appropriately

If your Hologon behaves as well as my Distagon, you will be delighted

good luck & let us see some examples when you get them properly Corner Fixed

:)
