[Contax] Aperture issue with a Contax body

<p>Hi,<br>

I just purchased a beautiful MT167.<br>

I own already an AX and another MT167.<br>

I own as well two 50mm f1.4, one 135mm f2.8 and one 28mm f2.8, all from Zeiss.<br>

The issue I have with the latest MT167 is that f number is shown different on the screen than it should be, difference is more or less 1/2 diaph.<br>

For example the ring is set to f16 and the screen shows f19; at the opposite side it shows f1.7 when the ring is set to f1.4.<br>

This happens on 3 of 4 lenses.<br>

None of the other bodies has this problem.<br>

I think about a small body gap somewhere.<br>

Anyway, does it change something on the shot condition, or is it just cosmetic on the screen?</p>

<p>If the body is reading the lens incorrectly the camera will not be computing the exposure correctly.</p>

<p>In the Contax line, the interface from lens to camera body is a simple mechanical interface. Your MT167 seems to be out of adjustment and requires some very basic service.</p>

I am interested to know how to do it.</p>

<p>Playing with free play between lens and body solves the issue, but it doesn't stay like this a long time.<br>

I need a long term solution.</p>
