Just got my Gossen digipro f light meter here's my question:
When metering with Aperture priority of course this will give me the shutter speed pair., now when I press & release the M button... the aperture value stays [ which is normal ] but the 3rd digit keeps -on changing...what is this small number next to the bigger number f - stop value.?
for example:
in AV priority mode I set the aperture to: f:2.01
then you press M button, the aperture value changes to: f:2.06
what are these smaller 1 & 6 digits?
I've read the manual it doesn't say anything about it.

its f1.4 plus 2/10ths to the next whole stop. it is a highly accurate meter. the same on the sekonic meters
sjms,
I don't get it bro... yours the f-stop is clocking 1.4 then you have 5. How do I enter this value in my camera? should I just put in f:1.4 & ignore the 5.
or shall I do this: 1.4 + .5 = f: 1.9? which rounds of to f/2.0?
and f2.0 will the one entered on the camera.? not 1.4?

no its halfway between 1.4 and 2.0 . remember you are now shooting your camera in manual including iso. you have the option to control you aperture up to , depending on your setup, between whole, 1/2 and 1/3 stops

bro pls be patient with me here...based on the picture you posted the f value is 1.4 and then small number 5.
what camera are you using?
in what mode are you trying to shoot your camera in?
(P)rogram nikon and the rest (P) on canon
(S)hutter preferred nikon and the rest (Tv) on canon
(A)perture preferred nikon and the rest (Av) on canon
(M)anual nikon and the rest (M) on canon
the difference between the 1.4 to 2.0 to 3.5 and on has been divided into 10 reading segments between each value. this gives a more accurate reading that may or not be usable depending on you camera and lens. if i were averaging using the small number 1-3 go to the lower whole f stop 3-6 shoot an both the lower and higher value 7-9 and the next higher value shoot there at that value. if shooting raw you have the ability to adjust in post for taste.

either f1.4 or the next higher stop you have. you do not have the ability to use that smaller reading other then to ballpark in whether you are going to go higher or lower with your available f stops. in the case of my particular reading in my room i would shoot at1/30th/s f1.4 and then at 2.0 and look at the differences on my computer.
are you shooting raw or jpg?
the advantage of shooting raw is the ability to adjust for differences in the image within a range. essentially, to an extent reshoot the image again in the computer.
also remember that you are metering incedent light. that is the light hitting the object you are shooting where a camera reads reflected light off the object.
you will not be using this in Av mode M is where you use an external meter.
in Av mode you you control the aperture but the camera will control the shutter. so any Aperture value you change will then cause the cameras computer to recalculate the shutter speed.
Notes: f/stop = sqrt(2)^(stop number + fraction) If you set your flash meter to read in tenth stops, it may read for example: f/8 plus 7/10 stop. This is NOT f/8.7. It is 7/10 of the way to f/11 - about f/10.
which you initially stated.
So in short this Gossen & Sekonic when they say 1.4 with small number "2" which is 1.4 plus 2/10th of a stop = f/1.52 actual aperture

Exactly. Also if you have a lens that has an aperture ring you can turn the aperture ring about 1/5 of the space to the next stop f2 if you're in manual mode.
The Digipro F manual actually does refer to this. Go to page 12 and under 3.2.5 Aperture Priority mode go down to the fourth bullet. The second sentence reads: "Automatic adaptation of the aperture in 1/10 stops to the measured shutter speed."
It's rather cryptic, but essentially what's happening is this very accurate meter is reading out that at a straight f1.4 you're very slightly overexposed at 1/60s and it gives you the correction value of 2/10 of a stop above that. You've worked out what that means for your digital camera but maybe it's time for Gossen to do those calculations for all f stops and make that an option for display in the meter.
I realized that I have to approximate the nearest f-stop on my camera based on the readings. the analog scale of this Gossen digipro goes full stop and half stops.
Yes you're correct. It's a great meter and perfect for me as I shoot high latitude film and my lenses have half and full stops. But they really do need to modernize it.
