Shutter button locking

bjake · 02-04-2012, 12:01 AM

Kx seems to have gotten into a setting accidentally or I am just now finding it that the shutter won't fire unless in focus
and proper exposure.Can't find a cure in the manual.
Thanks,
Jake

If you're in AF.C, it won't fire unless focus lock is achieved. Use AF.C or manual focus if you want to bypass that.

If you're using an auto focus lens with the AF/MF switch in AF, the shutter will only fire when focus lock is achieved. If you want to have a shot deliberately out of focus for one reason or another, switch to MF.

Had just got a F50mm and was shooting a completely overcast sky to check the sensor and lens for flaws but it wouldn't fire,camera in manual mode it fires.
Thanks,

Was the AF/MF switch on the camera in AF or MF? Did the lens hunt to obtain focus? If you were in AF and shooting at the sky there was most probably not enough contrast to obtain focus lock. If you want to check for sensor dust, put the lens on f22, the AF/MF switch on the camera on MF and manual focus to infinity, and then take the shot.

Will do that when this light rain stops.Did put camera on manual focus but left in auto exposure.Did find a couple linked pixels that were dirty or bad.Camera is almost a year old and have never used the sensor cleaning function.
Thanks,
Jake
