Electronics tend to be quite robust when used as designed but there are some mechanical systems that will inevitably wear out in the fullness of time. The failure could involve just one component or several. Sometimes Memory cards which aren't designed to deliver high sustained data rates can cause problems.
Originally posted by CarlJF How many shutter activations does the camera have? It might just be worned after years of use in continuous shooting...
28,865 as of tonight.
Even though I keep the camera in continuous high, I'm not always blasting away
At most I fire off 6-7 shots at a time when birds fly through the shot but otherwise it's always just a single shot.
Originally posted by WorksAsIntended If the camera shutter is gone, the results look complelty different from this.
I think the best guess so far is the aperture indeed.
You can check this by shooting a scenario with bokeh and see if the bokeh changes on those shots.
The problem is it's very intermittent. The majority of shots are just fine but it randomly over-exposes a shot here and there, but I'll do what I can to keep an eye on things like that.
Originally posted by ismaelg Hello,
A few years ago, I had a similar situation but the frames were getting darker instead of overexposed. I sent the lens (F50-f1.7) to Eric for servicing. It was not able to cope with the frame rate of my K5-II. After servicing, it's been working flawlessly for about 3 years now. Not sure if that may be relevant to your case.
Thanks,
Thanks for the comment, I just might have to do that but at this point I don't want to put any more money into this camera.
Originally posted by Crooski You can test the lens by opening and closing the diaphragm release manually
If it goes fast and smoothly then the lens is OK
If the diaphragm blades are slow and sticky, then the lens is wrong
I understand what you're talking about. Using the little lever on the inside of the lens everything operates smoothly and quietly, but maybe this is an early sign of the diaphragm problems/failure?
