Hi, When my D50 is in AF mode, it will not trip the shutter unless it thinks its focused (af-confirmation-spot being still). Is there a way for the camera to shoot anyway other than putting it in manual focus? I see a potential to loose photos just because the camera considers them out of focus... Regards
Custom Function 2 should allow you to change the AF mode from AF-S (auto focus - single servo, which is a focus priority mode) and AF-C (auto focus - continuos servo, which is a release priority mode and most helpful with moving subjects). Note AF-C will release the shutter regardless of focus so blurry images are a possibility.
Sorry Anthony, the D70 is release priority but the D50 is focus priority in either mode. It can be overridden with a lens with A/M mode, like the 18-70, by first auto focussing and then manually focussing as you shoot. I've yet to find a situation where it helps though.
There is an override possible, of sorts. You can program the AE-L/AF-L lock button on the back to only to AF-L (in the custom functions). Then, if you hold down this button before pressing the shutter release, then it will make the camera release-priority no matter what AF mode you're in. Think of it as a "shift" key that "shifts" the camera to release-priority, yet does so "on the fly" so that you otherwise have it operate as focus-priority.
It does concern me, though, to hear that the D50 is focus-priority even in AF-C mode. If that's so, how are we supposed to track moving subjects? That will lead to a LOT of missed shots.
