Problem with mamiya 7 meter

[jay_chadney]

<p>I just bought a user Mamiya 7 w/ 65 lens. I had a 7II previously. This camera has a problem with the light meter. When in A or AEL, the far right arrow in the viewfinder blinks no matter what changes I make to any exposure settings. When in manual exposure mode, the meter does not indicate the correct shutter speed I need to be at.<br>

I have only found one person on the internet that posted a similar issue. He never found a solution, but determined that it had to do with his 65mm lens, as his 43 and 150 metered just fine. This doesn't make sense because the meter for the camera is in through the lens......<br>

Contacts are clean, new batteries have been tried, etc. Has anyone ever had this issue? Did you get it fixed?</p>

<p>You are wrong, the meter is not TTL. Actually it's the little window just above the lens. I have had a 43mm that showed the same problem not continuously but from time to time. It was a lens circuit starting to fail that caused it. Since this was a used lens I just returned it and got a nice offer for a new one that I still have. I suggest you do the same....</p>

Sorry for the typo. When I typed ”is in through the lens" I meant to type ”isn't through the lens”.

I do not have the luxury of trying other lenses. How can the lens affect the meter if it is not ttl?

[Giovanni Cappai]

<p>The lens passes the information of the aperture chosen to the camera. This is one of the purposes of the pins that connect the camera to the lens.</p><div></div>

<p>Could be lens, could be body. If this camera performed like this when you got it , If I were you I'd be looking to send it back for a refund and buy another rather than agonise over cause and repair costs. </p>

<p>I had a similar problem with a 150mm lens which I had serviced/repaired and it is working fine now. Most of the time I use a hand held meter and when the lens was faulty the hand held worked fine as usual. Have you tried using a hand meter?</p>

[jay_chadney]

<p>Handheld meter? yes, I have a few I use, but I kinda wanted the "speed" offered by aperture priority shooting/metering. Plus the blinking light is irksome.</p>

I found a store with a camera and lens to so some testing. It is my lens that is causing the problem. What is a cost to fix?

<p>I had a similar problem. The contacts looked clean. But I cleaned them and the camera contacts with a soft (non abrasive) eraser anyway, and it worked. Good luck.</p>

<p>I've been frustrated by this problem for years! Thank you John, your eraser trick solved it! I had no idea it was something to do with the lens contacts - after giving them a rub with a drafter's eraser, I realized just how dirty they had become. I'm unbelievably happy to have this nuisance solved. A thousand thank yous for pointing this out.</p>

<p>Having exact same problem. Will try eraser. Is there anything else with which the contacts can be cleaned?</p>

<p>Gracias!</p>
