Yep, found the answer, it looks like ISO = ASA:http://en.wikipedia.org/wiki/Film_speedPentax *istDS, Minolta A2, Fuji F31fd, Ricoh R3my fotos: http://flickr.com/photos/kuuan/my movies: http://www.youtube.com/profile?user=kuuan..

How does ISO of digital cameras translate to the ASA of analog cameras?.

They are supposed to be the same..

Or asking differently:if I us a digital camera for shooting a sample at e.g. f5.6 and 1/60sec. at ISO 100, would that mean that I would get the same expossureon an analog at f5.6 and 1/60 sec. with an ASA 100 film?.

In theory, yes. However, some digital cameras use the REI method to determine ISO, and so they are a tad off. Canon DSLRs were known to be more sensitive than the rated ISO - see review of the 30D about the ISO/Sensitivity accuracy:.

Hope this helps...

Remember that a "digital camera" sensor is also an analog device...

Actually ISO (the international standard) is a combination of ASA (the American standard) and DIN (the German standard) for film (or sensor) sensitivity. For example, a box of Provia RDP III shows "ISO 100/21" meaning ASA 100 or DIN 21. Somewhere we got lazy and dropped the DIN. So for the way it's used, yes they're the same. It's a bit like having a new ISO standard for temperature replacing Celsius and Fahrenheit: "ISO 15/59" then having everyone just calling it ISO 15.Severinson.

I still find myself thinking "ASA" most of the time, hold habits are hard to die.Equipment in profile..

I take a great picture, they ask me about my expensive cameras.I cook a great meal, no one asks me about my expensive pans...
