Question about Canon EF-S 17-85MM F/4-5.6 IS USM Lens
I just purchased the 17-85IS lens and when mounted on the camera, it will only let me snap the shutter when the lens is in manual mode. Any suggestions.
This is because the camera will not expose a picture until the auto focus is locked. If you are shooting in dimly lit conditions, the AF might have a hard time obtaining a lock. Using the flash as auto focus assistance many time helps in this condition.
Another reason might be that you try to focus on even surfaces with low contrast. The auto focus work by sensing contrast. Even surfaces, such as a white wall or the sky, have very little contrast, therefore the auto focus will not be able to obtain a lock. The solution here is to point the AF sensor at something with more contrast, such as an eye, a pole, or basicly anything that have edges/lines.
I hope this help you!
