With digital you can use Live View, or similar, to ensure focusing accuracy.

Clearly my sentence states that you can focus with Live View with "digital". Although you clearly didn't comprehend it the first time so I'm not sure why you might comprehend it now. Have you heard of digital cameras and do you know they are different to film cameras? Where in my clipped and out of context sentence does it say that a film camera has Live View?
The entire paragraph is below.

You will get better image quality from an accurately focused image but not all focusing screens/viewfinders are equal. This is obvious to one and all but easily forgotten. Don't discount the importance of the viewfinder/focusing screen or your own ability to focus accurately.
Again, and with the benefit of the entire paragraph instead of a single sentence out of context, where does it say you have Live View with a film camera?
The "S" marking is only on the box, not the lens itself.
The term "pancake" has been applied rather liberally to several of the various Nikkor 50mm lens. The lens I'm referring to was the one originally sold in Japan and focusing down to 0.45 meters, other U.S. lens focused down to 0.6 meters. In addition the so-called "S" lens has a metal barrel and is multi-coated, U.S. versions of the 50mm f/1.8 AIS lens were single coated. Here's a current example listed on eBay (no connection to the seller): http://www.ebay.com/itm/271263179815...84.m1438.l2649 The seller clearly shows the differences in the lenses with the photographs on the listing.
Based on a reading of the development for the Nikkor AI 50mm f/2.0 lens on the Nikon website "The Thousand and One Nights", which refers to the "S" type 50mm f/1.8 lens, it's clear that the latter lens has a superior correction. Tale 2 on the page: http://imaging.nikon.com/history/nikkor/index.htm
"Compared with the previous model, the NIKKOR-S Auto and the AI Nikkor 50mm f/1.8(1980~) mentioned above, which had almost zero geometrical distortion, it is something of a pity that this lens did not have quite as good correction."
