The Admin post in the prior thread before locking it is the worst bullshit I've seen here. They cannot run a forum, put no work or thought into organizing the forums, and then try to claim their definition of assisted applied. Stupid beyond belief, so long and thanks for all the fish.

I thought for sure Nikon and Canon started making Interchangeable Mirrorless cameras. Maybe the people running the forum are using the Wayback Machine. This is pathetic.

I think it means that no thought was given into the new forum structure. The use of the word "Assisted" in the forum name shows that this 30 year old forum is going senile.

I've lost count of forum re-orgs over the past 20+ years, but this one is the worst. "Assisted Cameras"- Most cameras require some assistance. Film cameras need assistance loading, shooting, unloading, and developing the images. The process is different from Digital. Digital cameras require much more assistance, and type of assistance is much more complex. Likely to generate a different type of thread.

The SPD's used in the Nikons, and most cameras if not all- have a filter over the cell to block IR. It is 95% effective in blocking IR, is the same type of glass as used in digital cameras using CCD and CMOS. The alternative to SPD's with IR blocking filter is Gallium photocells, used in the Nikon FM and Konica FS-1.

When buying a camera with a corroded sensor: AVOID the M9-P and M Monochrom. The S8612 cover glass is thoroughly epoxied into place and is very difficult to remove. The M9 cover glass is held in place with epoxy on the sides, and can be removed by cutting it. This is what Jadon at Red Dot Repair stated about replacing the cover glass. The Epoxy on the M9-P and M Monochrom must be heated to soften it. This process can cause damage to the CCD.

Tomorrow Secondhand Leica M-E Typ240 Anthracite Grey Attractive Model Is Now In | eBay Ebay has sellers that are insane.

I paid $2500 for my M8 over 12 years ago, used with spare battery. It is zero-defect CCD, I use Raw Mode all the time with it. "IF" I sold it, would ask for $1500 as a sane price. The Epson R-D1.used to go for $900, somehow has gone insane.

With Liveview- a Simple adapter, this one was $25 or so. Minolta SLR mount to M-Mount. For a film camera, or an M8, M9, or M monochrom: you need an RF cam that moves with the lens- exactly the correct length. This one is made from the leg of a broken tripod, and calibrated using Copper tape. Cheap, Skyllaney would charge a few $ for a professional conversion.

Arthur- Of course Live-View would make it much easier to use a lens adapted to Leica mount. You would not have to worry about calibrating the lens to the rangefinder. Depending on the lens- this can be relatively easy. I used a late Valdai Jupiter-3 mount to convert the 1934 5cm F1.5 Sonnar to RF coupled LTM, then use a good quality LTM to M Mount adapter. I can also use it with my film cameras. The 5cm F2 Sonnar, i used a Jupiter-8 mount. The trick is to properly Shim the lens and then re-index the aperture ring. Amadeo sells Contax to Leica adapters that are RF coupled. and Skyllaney will convert lenses to RF coupled Leica mount. 50mm Jupiter 3 f/1.5 Information — Jason Howe Jason Howe hosts PDF versions of the instructions above. For newer csameras with Liveview- a Simple adapter to M-Mount (or which ever mount) is all you need. There are some great bargain lenses- like the Konica 50/1.7 and Minolta 50/1.4, and the Canon FL mount 50/1.4. For those- I ended up making an RF cam to use on the M8. It's a change from writing code.

Magnificent Seven by fiftyonepointsix, on Flickr Now I'll have to see if the M Monochrom has the bigger buffer. In all these years- never filled it up.

Sonnar_F2_1b by fiftyonepointsix, on Flickr 1934 Carl Zeiss Jena 5cm F2, wide-open on the M9. This one converted to Leica mount as shown previously. Lighting is from the Red canopy of the miniature Train we are riding in.

In the 90s, I used to have two optical engineers that worked for me. Being a computer engineer (going back 40+ years)- I'd tell them "When my work day is done, I want to use a lens that did not even involve a computer in its design". The senior optical engineer, working on a multi-Aspherical lens to match a sensor we were building softly stated, "Computers really did make this easier". As he fretted over the polynomial for the "Wiggle of the Surface" I'd also point out that the sensor was 320x200- and it did not matter much.

I had the CCD in my M9 replaced when the M10 was announced, and the M Monochrom the year before that. Leica replaced the main circuit board at the same time. Basically rebuilt the camera while they were at it. How long will either last- you never know, but the chances are good that they will go for a long time. It is the S8612 cover glass that is the source of most problems suffered by the M9. Earlier M9 problems included the CCD itself cracking, and of course electronics failures. The Back-Side Illuminated CCD with offset microlens arrays are optimal for the older lenses that I prefer. Optically, they are well matched to the older lenses. The 18MPixel sensors have fairly large pixels, meaning more efficient at collecting light coming in at an angle. Small pixel/ high-count sensors are not as efficient collecting light of lenses sitting close to the image plane. If someone wanted an M9, and could get one with the newer CCD in it- they know up-front that if the CCD blows out, they have a paperweight. This is true of most Digital products: components at end-of-life and no longer available. Whether it's the LCD screen of an M8, the CCD of an M9, or an embedded microcontroller or FPGA used in the electronics. Camera manufacturers are at the mercy of the parts vendors. One critical part out of production, or back-ordered for TWO YEARS the camera will be useless. Two Year Back Order: I just got hit by that. I had my hardware engineer design a new circuit board using different components. Something most camera manufacturers will not do. Otherwise we'd have a CMOS based sensor replacement board for the M9. That would not be hard to do, just manufacturers want to sell new cameras, not update the old ones.

Of course there have been many advances in photography since the 1930s. Autofocus lenses that are far faster, easier, and more precise than using an Optical Rangefinder built into a Leica. Prices on Film Leica bodies has shot through the roof. I bought my M3DS with 5cm F2 Rigid Summicron and 135/4.5 Hektor-M for under $1K less than 20 years ago. M3 made the Month that I was born. Yet here we all are, living a fairy tale of using Rangefinder cameras and Lenses. Obsolete Technology, obsolete for decades.
