That s what you do when at home ill and bored. 
Raw, converted to jpeg via nx2, no additional sharpening, level 2 in camera, auto wb, handheld, wide open of course. I tried to crop the same way.

Easy to tell which is which, i think, first is the Samyang. Two very different lenses, of course. I am surprised a bit, that the Samyang has a "smoother" bokeh.  |

Thanks for the comparison! Now let's see if the Samyang indeed does not sharpen up after stopping down...

Why is that surprising; the Samyang is famous for its smooth bokeh, the Helios is famous for its non-smooth bokeh. ;D |

At f/1.5
But I bet that at f/8 it's a different story...

ok, here are both, as yesterday first the Sammy then the helios, different lightning, setting as yesterday, except for wb set to direct sunlight, i adjusted the exposure on some, to adjust for brightness, from wide open to f8 in full stops:

#7
#8
#9
#10
#11
#12
now just don t ask me to compare them to the Vivitar made 85/1.8 i have  
due to resizing the differences are not that big, but in NX2 the Helios is a bit sharper, i think, if you want i can put them on my PBase gallery, there they don t get resized

the originals, same order as here, click on the first one then just click next, the Sammy ones are with the letter f followed by the fstop, the Helios ones are with the hf letters in the file name, followed by the fstop number.

+1 from me. Horses for courses. What suits one subject/setting may not suit another. Isn't this why we all have a drawer full of 50mm lenses - for different bokeh?

Helios-40 has a minimum focusing distance of 0,70m when Samyang has 1,00m.

Thanks so much for posting these comparisons. I've been going through a real dilemma of whether to save up for the 40-2 for awhile or get the Samyang now. This convinced me to go for the Samyang for the time being as useful as it's going to be, and get the 40-2 a ways down the road to go with.
Here's hoping it doesn't keep going up in price like crazy. That Helios bokeh is just out of this world gorgeous. I can hardly believe that nearly all the advancements that have been made in lenses in the past 50 years have been wasted on AF and zooms. |

Hello Abe and welcome !
What camera body do you have ?
I ask because I had a dilemna to buy my Samyang 1.4/85 : did I take it in Pentax K mount and mount it on my Canon Eos with an AF chip adapter P/k to Eos, or take it directly in Eos mount and glue an AF chip on it.
I finally chose the Eos mount and glued a chip.
Here is the topic :
http://forum.mflenses.com/samyang-85mm-focusing-question-t19774,highlight,%2Bsamyang+%2B85mm.html
I'm very happy with this solution. Focusing is ok on my 40D and 5DMkII.
Hope this helps.

Merci, Olivier, pour la bienvenue, pour l'information, et pour la question.
I actually have a 600D. Besides lens testing and rare portraits, I'm only really going to be using the cam for video, so that coupled with some absolutely breathtaking bokeh images from a Helios 40-2 on Flickr told me this place seemed entirely up my alley. I have no desire to waste money on AF lenses with crappy focusing rings when I won't' be using AF anyway!
Anyway, I saw the thread on glueing the chip, and while it seems like a possibility, I didn't read there what's wrong with just buying say, a Nikon mount, and getting an AF confirm adapter for EOS. I've heard hints somewhere that image quality would suffer, but I don't understand why. Will it make the flange distance off or something? Do you lose infinity focus? Because if not, it seems like that would be much easier and smoother, as neither my patience nor my fine motor skills are strong. I have this terrible feeling I'd get lazy and frustrated and screw it up. Additionally, I don't need AF confirm that badly, since the only thing it will do for my in movie mode is get rid of a tedious warning that asks me if I'm sure I have a lens on the camera. |

Anyway, do you mind if I ask why you went with glueing the chip rather than buying the Nikon version along with a Nikon-to-Canon AF confirm adapter? I've heard hints somewhere that image quality would suffer, but I don't understand why. Will it make the flange distance off or something? Do you lose infinity focus?

I glued it because I was afraid of losing infinity if I bought an AF confirm chip Nikon to eos adapter.
If you don't need the af confirm, it's ok with the eos mount.
Beware something :
If you use it for video, the focusing ring of the samyang is stiff. The Helios-40 focusing ring is very smooth.
Then Samyang min focus distance is 1,00m, Helios-40 0,70m.
Filter diameter : Samyang 72mm, Helios-40 67mm.
but... Samyang weight 565 grs, Helios-40 916 grs
Cheers.

Just tougher to move.
It should work well : http://vimeo.com/23910686
Just another thing about the Helios-40 : stepless aperture ring.
