I have downloaded the M8 firmware update and borrowed a coded standard (not wide) Tri Elmar (thank you Ray). I have a Heliopan IR cut filter and this morning I have taken four pictures in the following combinations. Here are the details in the order they come up in the Leica Gallery: 4. Lens detection on setting at UV / IR (this is an additional setting with the new firmware - before you just had Lens detection on or off). IR filter on lens. shutter speed 1/500 f8.0 28mm ISO 160 3. Lens detection on but not UV /IR setting. IR filter on lens 1/500 f8.0 28mm 2. Lens detection on but no IR filter on lens 1/750 f 8.0 28mm 1. Lens detection off no IR filter on lens. 1/750 f8.0 28mm All four pictures were taken at ISO 160 - shot in DNR and developed in CS2 . Details in the picture summaries. I used the 28mm setting of the Tri Elmar reasoning that corner correction (if any) would be greater with the wide angle view. Interestingly the shutter speed was 1/750 without the IR filter and it fell to 1/500 when the IR filter was put on.
