Depth of Field Preview

[Richard]

This preview button is somthing I really wish my D40 had and I am wondering if many photographers use this feature when DOF is important to you?

It was a little more important with film, where each exposure was more precious and you were not able to see the image right away.

I use it from time to time, but not often.

Also, typical DSLR cameras have fairly small & dim view finders compared to film SLR cameras. This makes it harder to really study the DOF in the view finder. It's just easier to shoot several photos at different apertures and sort out the best one later.

Thanks that makes sense.
