I have the 1.4 and 1.7 original version and a 1.7 RS - not a 1.4 RS.

The focus rings on the originals are plastic, a bit too thin for straightforward MF with a screw in hood. The RS focusing ring is far from perfect, but it is a bit better than the original with a screw in hood. Without the extra hood I find that the original is fine for MF.

The built-in hood has a very poor reputation, but it's not that bad on the RS. It's the same hood with one extra feature - it locks out. As the original slips in on a whim this is a huge improvement.

The RS is well built, it may not give the same level of confidence that the original 1985 lenses provide, but it seems to me to be virtually the same lens with a different focusing ring, a different rubber insert on the barrel and restyled 'AF 50' paint job. While I have had an original apart (word of advice, don't disassemble the helical unless you really have to) I have not been into an RS, so this is very much a surface view opinion.

My RS also has more accurate focus than my orginal 1.7, which requires a little micro-adjustment. I doubt that this is anything to do with the model, just sample variation.

Final word - if you are considering a Minolta 1.4 you should be aware that the Sony 1.4 has further features (ADI and AF-D) as well as a bayonet hood. Whether that makes it worth the extra cash is your decision.

I guess that would depend on the screw in hood? I have a rubber screw in hood on my 50/1.4 and it does not interfere.

Can't argue with that.
