That photo shows what nonsense these DOF Calcs are
Look how much you have between 3M and INF
How do you set 20M or 40M on that scale when the total
movement you have is about 6mm ?

Most of the calcs are based on the smallest dots that someone
can see on a 10"x8" B&W print..... but no two people see the same
and nobody has a 10"x8" B&W Monitor these days

It's also been revised at least 3 times and I don't think they
used the latest revision on the lens scales.

With a 28mm or 35mm lens just set it at INF and use f/8
everything from about 2M to INF will be in focus no need
to bother focusing at all and I'm referring
to sharp as sharp enough for pixel peeping not on a
10x8 print.

It's always dangerous using a camera without a strap

That's cheating the engines are all switched off and the
propellers aren't turning

Or is it just that Nikon and their photographers know
nothing about aircraft photography

(In their defence it does say Still Images )

It's like that Main Ford Dealer near me.... they only
sell cars ...... NO PETROL!!!

You've bored me enough already

Nikon had a very popular camera that was made to use like
that.... F3HP The entire viewfinder could be seen from 25mm
away. Useful for spectacle wearers which is probably why they
sold well.

Beginners Luck!!!

Do any shops near you give cash back on empty
beer bottles? I could send you some....

The Yongnuo RF-602 Radio Triggers won't work with
Pentax cameras at 1/180th. They are OK, but not quite
100% at 1/100th. They leave a black band across the
bottom of each shot.

I've gone back to Wein IR triggers partly because they
are very fast and I can trigger the flashes for a meter
reading using the Pentax IR remote or a high power IR
remote such as the Seculine.

Some good example photos here.....
