I've had this problem a few times and wondering if it something i'm doing, an issue with the camera or 'normal'?
Here is the scenario, i have a powershot s110, i use the camera and try out the same shot in various settings, ie full Auto, Tv priority, Manual and Av priority and i've noticed that if i do this when i get to Av priority it will not let me go below 5.0. It's greyed out. Doesn't matter what i do it limits the aperture i can use... which doesn't make sense to me since i've set it to Aperture priority - why can i not set it what ever i want? why can i not go below 5? BUT if i shut the camera off and turn back on, all of a sudden i can go as low as 2.0. Now having said that i haven't figured that out (or remeber to) at the moment so will move away from that spot so shot is different. Once i run into the Av issue i switch the Manual and even there it limits the aperture i can use ;(
Anyone know why this may be happening?
Thanks Scott!! That does make sense now and really does help! Greatly appreciate the response!!
Will have to run out and test it! 🙂
