I've had a similar issue in the past with my K20D + DA*16-50 + AF540FGZ.

There are two reasons why the camera may not trigger the shutter:-

1: The camera has not locked focus.
2: The flash has not recycled to a ready state.

In my case I was using the outfit in a park, at night with low ambient street lighting, filming parts of the Roman's and Carthaginian's fiesta in Murcia this summer.

My camera refused to fire on numerous occasions and I think the main cause of my problem was the inability of the camera to focus properly in low light.

Your Profile on talk-photography indicates that you have/use a Canon 40D.

Just buy anything. You'll soon know whether you like it or not.

You posed a question on that forum about the difference between EF & EF-S lenses. I'd suggest you do your own research and determine roughly how big an investment you might have to make.

Thanks.
