Just been viewing some of the entries for the 'Holiday Time' competition and looking at the exif data.

One shows the following information which seems to be giving two conflicting values for the aperture used:

Quote:
F-Stop: f/8
Aperture Value: f/6
Anyone help me make sense of that please?

I'm not sure but I think this is a factor of a cropped sensor.

The F number doesn't change as it's the relationship between the focal length and the aperture size.

In a cropped sensor camera the F number stays the same but as the lens is effectively increased then the Aperture Value is, in effect, 1/3 larger.

But if anyone has a better idea....
