Going for 85mm f1.4 or 135mm f1.8 for portraits?

I'm trying to convince myself to get a 85mm f1.4 (those manual lens from Korea, you know) for portraits, because some say it's the best fl for that purpose, and because I never had a 85 before I do, however, love 135mm, and someone offer me a used 135mm f1.8 within the price range of that 85mm new. Any suggestion?

The 135/1.8 is tougher to find but it's pretty long on APS-C. Still, you can always find a nice 85/1.4 Samyang.

I find 135mm too long for portrait work on APS-C ... have used my D FA 100 WR for it ... works if you have enough room, but it's really the limit for me ... J

Yeah, it's long, but I do portraits outdoor, that's why I love 135's

Wow, I wish.. It's just regular 135/1.8 with a 77mm filter ring, but without the '*' thingy

What I love about 135 is the compressed background. I read somewhere that 50mm, 85mm, even 100mm is almost identical in terms of background compressing.

The only 135/1.8 I can find in the database is an A* model that typically sells in rhe $1000+ range.
http://kmp.bdimitrov.de/lenses/primes/tele/A135f1.8.html
https://www.pentaxforums.com/lensreviews/SMC-Pentax-A-Star-135mm-F1.8-Lens.html

So, if it is a 135/1.8 and you can get it in descent shape for what a Samyang 85/1.4 is selling for that's a steal.

Is it the Porst 135/1.8? That's a good lens. If it's the A* jump on it, for sure.

well, The A* is the 'irregular' one, so anything else is sort of regular

Well, if I'm going to the 85mm road, I'll get the cheap Korean 85's
I'm one of those manual-focus junkie, so to speak
But again, the 135/1.8 I had in mind is Sigma made..

50, 85, and 135 are all very different focal lengths. If 135 is your favorite, I would say go for it.

Anyone have a sample shots of the same subject with both 85mm and 135mm? Thanks!

Well, if the A* is the only 135/1.8 Pentax made, I'd consider it a "regular" 135/1.8.
