Comparison between a Samyang 85/1.4 and a Helios 40 85/1.5
I did this comparison out of boredness, being at home ill, in an another forum for Manual Focus lenses enthusiast, where it sparked some interest. Two very different lenses, the Samyang is well known, the Helios 40 is a russian 85/1.5 lens in M42 mount usually (i have the M39 mount), it doesn t reach infinity on a Nikon body (although it can be modifyed), which is famous for it s "swirly" bokeh (not rapresented in this comparison). I have the silver, older version, the lens is 48 years old and a real beauty. Shoot in RAW, converted in NX2, in camera sharpening level 2, no additional sharpening, wb set to direct sunlight, i adjusted the expousure on some to level the brightness. Handheld ! From wide open to f8 in full stops, first the Sammy then the Helios, then the Sammy...and so on. These are resized, for the 100% click here: http://www.pbase.com/tomasg_71/sam_hel
I assume the first is the Samyang? That definitely looks better, clarity, color and bokeh, all the way through.
.....Just from an amateur......
Yes the Samyang is the first, then third, fifth and so on, sorry but i don t know how you say this in english "every second one" maybe?
The Samyang is of course better in all those aspects, contrast, clarity...even in the "classic bokeh", but the Helios is just...
I have an old Vivitar made 85/1.8 lens, known for it s 15 blades iris, i think you are asking to see how the overall sharpness of the Samyang is? It doesn t sharpen a lot when stopped down, if this is what you think, in fact if you look at the 100% crops, i think the Helios stopped down is sharper, just a bit. But the Samyang is special for it s wide open performance and for it s smooth bokeh.
Quite an interessting comparison, thanks for taking the time! Clearly more modern designs (and coatings) exhibit more contrast and perceived "punch" suitable for the style and taste of today. The Helios is a fascinating lens however.
