Coding of non-leica lens

[FBA]

Hi bros,

I have several M hexanons that I'd like to add the 6-bit code for my M9. Do you know anyone/shop that can do it and how much will it cost?

Thanks!

Another such product is:

match Technical Services - Coder Kit

You may be able to get it from Chiif Cameras.

Thanks for the input bro. Is this method reliable? I'm a bit nervous of coding the lens myself...butter fingers lah!

I was interested too but I believe the current DIY methods only form a temporary coding. It wears off after a while

I drilled the Recess for VC15mm(M mount version) myself!

Wow. Did it it work?

does coding give aperture data too?

That's a bit too advance for current L technology me think! :bsmilie:

Interesting... did you use a drill press for it?

the coding only helps you to identify the lens... in some instances, you can even identify between lenses of same focal length and max aperture, e.g. Summilux-M 50/1.4 ASPH and pre-asph.

shooting data (coded or not coded) would only include shutter speed, ISO, mode, WB, date/time, etc... no aperture reading.

I used my dentist's drill

The data does show f value at least in iPhoto, Preview & Photoshop CS5 on the Mac. It may not be the actual value but an approximate one.

this is sometimes done inferred from the recorded light value, after accounting for ISO, shutter speed and EV compensation...

Cactus is correct. I had experienced this issue and had written to Leica HQ seeking their explanation to the inaccurate reading I got from my lens and this is more or less how they replied to me. It's software generated and an estimation at best. From my experience, the software tends to indicate a smaller aperture setting than it actually was and usually with the aperture opened wide. There is no physical, electronic nor optical link between the lens aperture setting and the camera other than the amount of light let into the camera by the aperture.
