Hi i tested my a470 and a2300 today and found something odd regarding the set values.It seems both cameras can accept an input in mm up to around 200mm and the results are oretty pecuse.However as you start to roan above 300 the output focus is always lager than whats input.for example input 225mm on an a2300 and the focus is actually about 300mmInput 280mm and the focus is 700mm, 350mm in and 1metre out. 1000mm in and 3000 out etc.The a470 seems to behave similarly.The zoom is at zero (any increase in zoom dramatically alters the results.Is this a known issue being camera dependant.Are there any threads i could be directed to. All my searches take me to sd override in script.regards
From what you say Reyalp, i'm guessing that if i manually focus onto 'an item' on my focus test range ( a plank of wood with numbered pegs at set distances with a detailed target pattern) then swap into chdk without turning the camera off first, and then view the numbers displayed in the "overide subject distance () the numbers should be the focus value ?? ( i had noticed they seemed to change but was not aware why).If this is the case i can make a matrix card to accurately set my focusing to reasonable levels (i'm thinking that this should also be possible for the other cameras without manual focus, by focusing onto the desired target with a 1/2 button press, then swapping into chdk and viewing the numbers??......All sounds too easy.
Thanks Waterwingz, it ie that easy.I will Produce a chart tomorrow.Fortunately i have 2 identical A470's so i will repeat the test and see if there is some level of repeatability.
