After hesitating for a while, I decided to make the move on a mint-looking R6.2 on eBay.
It arrived today, and in the meantime I had discovered an old thread where cracking inside an R6.2 mirror-box is described:
On opening my new camera, this is the first thing that I looked for. Sadly, the cracking was there.
The other issue that I am experiencing with the camera may or may not be related to this cracking. It is very peculiar:
- I began by using a v.1 135mm Elmarit and observed that the R6.2 (properly focused and set to selective metering onto uniformly lit, mid-reflectance surfaces) was reckoning correct exposure to be at f/11 when correct exposure (repeatedly measured by a Seconic L-758DR on spot meter and confirmed by incident readings, both by this same meter and a 308S) was two stops greater, at f/5.6.
- Then, sticking on a 100 Apo-Macro-Elmarit, readings were exactly correct!
- Confirming with a 280 f/4 Apo-Telyt, readings were also correct (actually, maybe off by no more than half a stop, or so, but within a margin of error, in any case).
- Switching to a 80 Summilux, readings off by a stop (camera asking for f/5.6, when actually f/4).
- Finally, on a v. 1 50 Summicron, off again by two stops (camera asking for f/11 for a f/5.6 subject).
My only guess is that, depending on the lens used, there is more or less internal reflection caused inside the deteriorated mirror-box, throwing off the meter. Why a 100 and a 280 would be fine, but not a 135, however, seems strange to me. A possible pattern: newer lenses seem to do better than older ones.
Anyway... what could be going on? Have other people experienced this? Should I return the camera?
Thanks for any and all advice!
