K7 K5 Gross Over Exposure Problem

normington4 · 2011-03-02T17:06:37+0000

I am new to the forum, and since 1981 have used an ME Super, SFX, Z1, istDS, K7 and now K5. My K5 gave a significant number of gross over exposures over 903 shots on a holiday with continuous sun. Pentax Technical had no explanation on being sent examples, so the camera was rejected as 'not of merchantable quality'. My wife then persuaded me to buy a K5 before the VAT went up, and the 20th shot of one of the blizzards gave a complete white out. When I realised what had happenedan, an identical shot several seconds later, was OK. Pentax Technical have seen these 2 shots, and again say they do not know what has happened. I can not believe that I can be only person to have been so unlucky to have had the only camera of both the K7 then the K5 production lines to have had this fault !!!! Is there anyone else out there who has had this fault ? - Billy

Thanks for drawing my attention to the AE-L lock, it's actually very easy to inadvertently brush the button with your thumb whilst holding the camera, I have had one or two incorrect exposures in the past which appeared to be random, now I know what to check for.

All very interesting,Especially as today I had some over exposures with my K20D, I finaly noticed that I must some how pressed the +/- EV Compensation button whilst turning the front dial and in doing so had set + 3 compensation. HMMMM I never had this problem with my Brownie Cresta back in the 50s.
