I'm sorry to tell you, but your pics illustrate what we mean by "busy/nervous bokeh"--especially the second pic (with the smiling guys having beer); just look at the left side of the second pic: bokeh is anything but creamy/smooth there.
Got an example of what you consider "creamy"?

Just interested to know, not being facetious...

Plenty of examples in the Samyang thread, but this page has a few good ones:

I have not used the 85/1.4, but I sure like the DA70 for mid-aperture landscapes.

The following image is similar in composition to my one. To be honest, I bet if that was set to f2.8 the bokeh wouldn't be that much different.

Maybe it's just me, but I can't say the sample pics make we want to go out and buy the Samayang/Rokinon 85mm over my DA70mm

I can't say how DA 70 compares to Samyang 85 at f2.8; I only have the latter. Still, lenses differ with respect to bokeh even when used at the same aperture. Optical construction, focal length also count.
This photo was taken at f1.8. I've just checked.

Here is a sample of the Samayang 85mm @f2.8 (from the thread you linked)

Samyang 85/1.4 @ 2.8 | Flickr - Photo Sharing!

EDIT: Apologies if I come accorss as argumentative, all I'm attempting to illustrate is that comparing a lens at different apparetures is a bit unfair. Personally I think the DA70mm wide open still has rather smooth bokeh, although I can bet if it was capable of f1.8 it would be just as good as the Samayang/Rokinon

Yes, and bokeh is pretty smooth in this case, too. But the distance btw. subject and background and how much 'crowded' the background is are other factors on which the quality of the bokeh depends.\

Anyway, bokeh is largely a matter of taste. If you're satisfied with the results you're getting with the DA 70mm, stick to it. The DA 70mm has quite a few advantages over the Samyang 85mm: tiny, extremely light, AF (and fast AF!)... I think of them as being lenses with different purposes. The Samyang isn't a street/travel/action lens.

Yes, very true. I'm more than happy with the DA70mm. Since I've purchased this lens my photography has improved dramatically, as have the results.

They are definitely different. If the Samyang 85 were AF it'd be near perfect in my book. Because it's not I own the 70 Ltd too. As for Bokeh, to each their own. The 85's is amazing, when you get it right. The 70s isn't bad, but its not as smooth.

DA70 has quite fast AF, however not very accurate (or can be K-5 problem). Not entirely CA free. Definitely not a macro lens, neither samyang is. And bokeh is not smooth, not really interesting (interesting is what I call Helios 40-2 swirly bokeh) and guys.. 2.4 is amlost 2.8 which is not that fast and can be found in good quality zoom lens.. I still do not have a samyang in my palm but somehow I know it will be a great feel to take pictures with it.

Was just about to sell my Rokinon 85mm to get the DA 70, thinking it was the better deal. Just killed that auction and am keeping the 85mm after reading this thread (in the nick of time too!)

Don't get me wrong, the 70 is a nice lens and the AF is great - but the 85/1.4 is a steal of a lens that in the right circumstances really produces some stellar photos.

Well, I have all three (77), and I can't bear to part with any of them. But only the 77 does 3d.

I am not a catch in focus expert, but wouldnt it suffer from the same AF big focus "points" problem? I just worry that people may get frustrated with this lens thinking it's soft when all that happened is that the CIF caught the ear instead of the eye.
That is why I am a huge proponent of the S-type focusing screen.

Yes; this is what caused me to sell my copy.

It was a fine and very capable lens, but you need to be patient and able to take the necessary time to get the best from it. It helps if your subjects are relatively static. Most of what I shot with it were portraits of my young kids and the near impossibility of getting them to remain in position long enough to nail focus meant I hardly ever got the shot I wanted.

I've also got a DA70, which is great for candid shots and travel, but bokeh is not its strong point. I changed my Samyang for a K 85/1.8, which has a nicer feel to the focus movement, excellent bokeh, better colours and f/1.8 is plenty fast enough for me, I don't really miss f/1.4.
