Just saw the digitalrev review on YouTube, the Japanse guy says the only downside is that it's not bokehlicious.
I thought the 50mm gave quite a beter bokeh than a 35mm. Can anyone show comparison pics with for example 50L, is this one's so much smoother or is the Japanese guy nitpicking?

Japan and Hong Kong are different places, bro.

Yep whatever, but this was not my question :)
Anyone finds a comparison between 50 1.4 Art & 50L?

Wtf. The 50L is smoother than the 50 Art, and the Korean whatever guy is not nit-picking.

You do know that there are whole LENS SAMPLE ARCHIVES here that you can just find yourself, right?

Yes but you can see it better with a real test with the same pics of both lenses... Maybe they where compared somewhere?

Is it only due to the f1.2 VS f1.4 or amount of glass?

Hong Kong is in China. It was a British territory until a few years ago (hence why some residents have English accents...like Kai). Many residents also speak Cantonese instead of Mandarin (Mandarin is the official "Chinese" language). I've seen some vids where Kai does poke fun of his Chinese major neighbors. Just thought I'd give a short Civics lesson on Hong Kong so that we don't have more comments of DigitalRev being "Japanese" or "Korean" :-)

You should read my sarcasm "Korean whatever" as a retort to his ignorance and previous post.

Will do. Just thought I'd give the short geography lesson for the benefit of others that might be reading and aren't in the know. I do sometimes find it surprising how many folks in the world don't try to learn much about other parts...not knowing where Hong Kong is is not the worst offense I've seen.

I'm not sure comparing one focal length against another is all that relevant for most folks. Longer focal lengths will give more background blur for any set framing and aperture, but that doesn't really speak all that much to the bokeh.

Bokeh is a function of the design of the lens, and a lot of lens features that are good for making a lens sharp and accurate in focus can be bad for bokeh. Specifically, aspherical lens elements and floating lens groups often make for hard-edge blur disks, which make for busy bokeh.

The Canon 50/1.4 and 50/1.8 are examples of fast prime lenses with an ability to really blur a background, but which also have really bad bokeh. Both are very prone to hard-edge blur disks, and the 50/1.8 makes weird pentagons when stopped down.

The Canon 50/1.2L has very good bokeh at any aperture.

The Sigma 50 ART is between these lenses, better than the 50/1.4 (which isn't saying much) but not nearly as good as the 50/1.2L.

Just found some real life comparisons here, do you find the Canon so much better in these examples ?

Here a guys says : I also find the bokeh on the Sigma much less busy/distracting and more pleasing than on the 50L, I was beginning to think it was just me
http://www.canonrumors​.com/forum/index.php?t​opic=26868.0 (external link)

The best Bokeh, is subjective and one can prefer the "dreamy" look, but I think they are very close.
Just wanted to know as some people say the 50L's bokeh is so much better.

Anyway, the Sigma is cheaper and sharper at f1.4 & f2 than the Canon and that is also an important factor.
f1.4 : http://www.the-digital-picture.com …omp=0&FLIComp=0​&APIComp=0 (external link)

I wont deny the 50A is sharper. Those bokeh comparison picks look to be reversed IMO.

Well "bokeh" is a subjective term. The Sigma is sharper, but bokeh is relational to the absence of sharpness. Since the Canon can have a larger aperture, I could see why it would be more "bokehlicious"

He has an English accent because he was born, raised and educated in England - .http://www.kaimanwong.​com/about/ (external link). Nothing at all to do with whose territory it was. Native Hong Kongers of Chinese extraction would almost without exception have had Cantonese accents, as Lok does on DRTV.

But 'bokeh' is not the same as 'how blurred' the out of focus areas are...which is merely related to the aperture diameter.

'Bokeh' is 'how pleasing or disturbing' the blur is, determined in part by the optical design and the amount of correction for spherical abberations (a highly corrected design actually can have more disturbing bokeh than a lens with less correction of spherical abberations), in part by the aperture shape, in part by the transitions of brightness within the blur disk.

So two lenses with same aperture diameter will certain have 'same degree of blurriness' but not necessarily be equivalent in how disturbing and abrupt or how pleasing the blur appears and therefore one is 'more bokehlicious'. A 500mm f/8 conventional optic will generally be far more 'bokehlicious' than the 500mm f/8 mirror optic, although both would have equal intensity of blur.
