Resolution

Shame no one uses this forum. How long before the plug is pulled.
Before that happens here goes.
When the first 35mm SLR's became available (60's) up until the late 80's and before the zoom lens hade reached it's current state ofdevelopment no self respecting amatuer photographer would ever dream of attaching anything other than a prime lens to his camera body.
All the magazine rewiews of new SLR's during this era were totally obsessed with lens resolution and the holy grail Line's per mm.
All the major manufacturers had a lens with at least 100 L per mm and some achieving up to 130.
I am open to correction here but is it not a fact that with a standard 10 X 8 print viewed at the normal distance it is not possible for the human eye to detect more than 15 L per mm. I do of course realise that high resolution is essential for selective enlargements and poster sized prints.
This leads me to my question having jumped to the digital age.
How many Mega Pixels do I need to equal or better this basic 15 to 20 L per mm achieved with 35mm film
I am constantly suprised with the results I can get with a basic 2MP compact but of course I accept it's limitations.
Stu.
