Clunk, I have a some nifty DoF calculators from Thom (www.bythom.com) which work it all out for you.
If you want, let me know what focal distance is and I'll give you the start-of-focus and end-of-focus distances at a given aperture Very handy
i would recommend this:

I left the Exif data in the wasp pic.
Looking at the dofmaster chart, I entered the values and it gave me this for f/2.8.
Subject distance 6 in
Depth of field
Near limit 5.99 in
Far limit 6.01 in
Total 0.02 in
In front of subject 0.01 in (50%
Behind subject 0.01 in (50%)
Hyperfocal distance 2639.7 in
Circle of confusion 0.019 mm
And this for f/4.

Hyperfocal distance 1867.3 in
Circle of confusion 0.019 mm
I like the circle of confusion, that kind of sums it up
This is probably one of the closest shots I've ever got.
I can't remember the settings but it was with a 50mm and some extension tubes.
loving the macro's guys

Bobster .... funny what you see wondering around Dorset these days, huh. Bloody global warming.
Some great pics recently...

Dammit, stirrer
Seriously though, I could have used the fill light to improve the colours on the planes, but with the sun being above them, anything I tried seemed to wash out the other colours. I think I achieved a sense of motion in the shot, which is what I was pleased with. Only my second airshow, so plenty more practice to come
That's one of the best I've seen of the Arrows, well done.
Thanks and another
Those arrows shots are magnificent - without the sun glinting off the cockpits they could be oil paintings rather than photos!
Time to bring the standards back down with more compact P&S shots - lavender's already finishing now and the honey bees have only just found our garden.
Wow - some very nice pictures here
Love the animal ones, but best of all the lavendar and air show pics.
