Leica Leica M9 sensor repair

Hello, I’m sure people are already tired of hearing about this particular issue but I might as well get this out there.

But first a brief background of who I am,
My name is Jadon Rosado I’m a camera technician currently working for a shop in Oregon. I’ve been repairing cameras professionally since I graduated highschool (I’m 20 now), I came across some Leica factory manuals and thought myself the ins and outs of the M system by the book. Ive since used my own cameras to experiment different methods for odd ball repairs such as re-cementing/resilvering prisms, blocking framelines and more recently repairing sensors!

Over the past 2 months I’ve been working on a method to replace the corroded s8612 glass in the Leica M9s, I posted some of my later findings in another Thread. About 24 hours after my first post it was announced that kolari vision will replace the glass for $1000 and another company came out a day later saying they’ll do it for $1500. looking into these methods they seem to be much more invasive the latter even seeming very rushed, but who’s to say I’m not going to pay $1600 for something I can do myself so I can’t compare. Anyway, I’m coming out to say that I’ll be offering the repair as well. I’ve put a lot of thought into it and spent possibly too much time testing but I wanted to be sure. This method uses a glass that is similar to the original S8612 with the exception of it having a slightly higher transmittance across the entire visual spectrum. What you as the shooter will notice is a slight increase exposure and a slight drop in contrast due to the wider range. In other words it goes from looking like Kodachrome to looking more like Portra 400. I’ll post some test shots below, I’ll keep this thread updated with when I’m ready to start bringing in repairs for those that are interested!
And I should add that my conversion will only cost $700!

edit: I forgot to mention that the last two images have a small defect in the lower left hand corner and a small magenta spot in the lower right. This is damage to the sensor itself cause by me. I used this sensor to test ways of cleaning the raw sensor prior to installing the New IR cut filter. I’ve since found that a gentile putty like rodico (used for cleaning watch dial) works best, the micro lens array on the sensor is extremely delicate and direct contact should be avoided if possible. with that being the said those two images were used simply to demonstrate the colors and the increased transmittance of the visual spectrum. the first image of the hood emblem is taken with a replacement sensor using the same glass. With that sensor I made slight changes to my method that reduced the risks of damaging the sensor.

I should also mention that I am currently repairing Leicas for a shop, I’m not just some guy messing around with his camera in his free time. I’m well aware of the work I do and the machines that I operate on. These are very expensive pieces of equipment and deserve proper care and the fine tolerances set by leica should be respected and set meticulously. I keep that in mind with all my repairs, I’ve never let a camera leave my bench even slightly out of tolerance and I plan to keep it that way. I’m only putting this out there because I’m often questioned about my repair expertise because of my age. It’s understandable. As any Leica shooter would know, they’re not cheap and it requires a certain amount of skill but you don’t need to be a 70 year old leitz veteran to fix Leicas properly either!

No I am not. For me, it's the CCD sensor or nothing when it comes to Leica, the files can not be replicated in later models or other cameras (although what I have seen from the Nikon D7000/7100 & Ricoh GR/GRII comes very close indeed). So the only way I'm going to continue to use a rangefinder is if the likes of you continue doing what you're doing. Please keep up the good work!
