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 300mm
Input 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.
