Partial shutter speeds until 1second.

Don't you get confused when camera starts to display shutter speeds in seconds before they reach 1/1=1' in length?

E.g. when with my film and P&S cameras i've used that everything under 1 sec. is a portion - 1/15, 1/8, 1/4, 1/3, 1/2.5. Everything equal or over to 1s is a round number: 1, 2, 4, 30 etc.

Why has Pentax choosen to display values under one second as decimal fractions? Eg. 0.3' 0.5'. And at which point it changes appearance. Smallest fraction i've seen i think is 1/4 but i'm not sure.

What is 0.3'? 1/3? Or 0.6" = 1/1.66666?

Is it because i use 1/3 EV values? Maybe 1/2 EV has good enough precision and i should use that mode?

.3" is exactly what the decimal implies, 3 tenths of a second. .6" is six tenths of a second. Just like .5" is 1/2 second. When it goes to decimal it is no longer a fraction of anything, it is exactly what the decimal value states.

Why they did this, well that I have no clue about. But notice when you hit the fractions like 1/30s the display shows 30 with no " after it, so you know it's 1/30s rather than 30".

I imagine it's just easier to show 1/1000 of a second as 1000 rather than .001", or 1/250s as 250 rather than .004"

But when you start dialing through the shutter speeds and you hit what would be 1/2s, how do you display, as a 2? But 1/2s is only two stops away from 2 full seconds, which is maybe why once they get past 1/4s they change to decimals?

I may be totally off base I'm just trying to come up with some logic to it.

I also hate how the slow speeds are shown. It is confusing and always makes me stop for a second to figure things out. Have lived with it on DS/K10D/K20D/and now K-7. Still can't get comfortable with it.

thanks

Aye me too, but unfortunately mines down to having to work with poor lighting conditions.

The way shutter speed is shown (1/1000 sec as 1000) is standard for all SLR cameras that I have ever used.

10 = 1/10 sec
10" = 10 sec

I don't think this is something that Pentax has invented. Even Nikon does it this way
