Hello,
After originally reading this post I began asking myself,
"Just what didn't I personally not like about the 135mm? Or do I even really remember?" (hadn't owned one in SLR for more than 2 decades).
I do like this distance in RF (which I'm told is the absolute exteme for accurate parallax focusing), so why didn't I like the one I had in the 80's on my XG-1? These were the musings I was mulling over when a friend stated he had a Rokkor-X 135mm for sale for about 1/50th of what it sold for new - so I bought a lens that prior to this thread, I wouldn't have taken as a gift.
I have really enjoyed using it. No images back yet, so I can't comment on the quality of the glass - but for walking around in an amusement park with the kids - it's better than a 90mm. Don't have to be as close to get the same shot - much easier to get that "look" without telling them to slow down or come back to you.
I'm guessing the issue with the older 135mm had to to do with its pedigree ("Albinar" which I think was BEST's house brand) and its performance or lack thereof - or something that one of my two mentors at time said about it combined with a comment that 90-100mm was preferable (I worked in a studio doing studio work) probably had something to do with it as well.
OK, I'm not sure I'm an acolyte, but I definately see it's place in my arsenal. Thanks for the thread!
