Canon bokeh vs. Zeiss bokeh

shortpballer · Oct 22, 2009

Here is a picture I took with a canon mount zeiss 50 1.4

And a picture with the Canon 85 1.2L

I was surprised at the COMPLETE difference in the looks of the bokeh. Both are very pleasing. The zeiss seems to give a more film bokeh, while the canon seems to give a really creamy bokeh.

Thanks for the pictures; I personally like the 85mm 1.2L better.

Personally, I am more concerned with the fact that you are drinking Natural Ice.

welll DUH there's going to be a difference, You shot with a 50mm and an 85! not to mention the 85 is faster!

Failure IMO. This is like comparing a ford F-150 to a bmw, DUH the BMW is faster and smoother, it's a car, not a truck!

Well first off, this isn't the most accurate test. Simply the difference in aperture (1.2 vs 1.4) is going to have a profound affect on bokeh.

Second, the focal length has a big influence as well.

First of all if you guys would look closely there is a HUGE difference, and it is due to the design of the lenses. The zeiss produces more choppy, film-like bokeh.

And by the way they were both taken at 1.4 for comparison purposes

i think i like the second one better.

what does "film bokeh" mean?

I would say it applies to the aperture blades, In film days lenses had less aperture blades, the bokeh comes out more choppy. With the 85 1.2 it is circular, so the bokeh will look very creamy.

Thats what I would assume... lol! someone correct me if I'm wrong.
I just wanted to show you guys the difference as I was amazed

I think it will make more sense if you compare a 50mm lens to a 50mm lens.

well couldn't exactly do that, as I do not have a canon 50 at this moment.

The Cosina-made "Zeiss" lenses are not known for their creamy "bokeh," regardless of the different focal lengths used here. But yeah... this isn't the most accurate "test."

No surprises,really. There is no such thing as "film bokeh". The Zeiss brand of lenses has long been known to produce bokeh that is,well, often jarring. In recent years, and I mean very recent years, the term bokeh has come into vogue, and is widely misused. The term was first brought to the attention of the English-speaking world by Mike Johnston, a little over 12 years ago now.

To many people bokeh means "out of focus specular highlights", which is only one aspect of bokeh; DScience loves making photos that have small, point sources of light in the background, but that is only the portion of bokeh known as the "specular highlight rendition". OOF specualr highlights are fun to shoot, and a lens that renders OOF specular highlights with a nice shape is fun to own and shoot. But specular highlight rendering is only one aspect of bokeh.

To many people, bokeh means "an out of focus background". That is not what bokeh is. To many people, the more out of focus the background is, the more they think they have achieved "bokeh". Again, it's not a quantity thing--it's about the quality, the character, and the characteristics of the out of focus areas that a lens creates that makes up bokeh.

Last night I was putting together a list of articles on bokeh from some sources that are accurate, and reasoned. Here it is.

Here is an example of a person with a very shallow understanding of bokeh, and who has developed a bunch of bokeh "textures", thinking that bokeh refers exclusively to out of focus specular highlights or out of focus lights.

Balderdash.

One, the number of blades has very, very, very little to do with the quality of bokeh. Two, the shape of the aperture has only a little to do with the quality of bokeh, Three, "in film days" lenses had easily as many and very often more blades than modern lenses.

Check out this link that was posted in another bokeh thread here recently:
http://www.rickdenney.com/bokeh_test.htm

The biggest factors affecting the quality of bokeh lie in the optical design. The 50mm f/1.4 shows what I consider very poor bokeh. Small round highlights (there's one on the right side of the image) show a bright ring. This is cause by slight overcorrection of spherical aberration. The 85mm f/1.2 isn't fantastic, but is much better. It seems to show evidence of a very slight bright ring causing the blur to have too much of an edge (look at the edge of the white roof in the center; it doesn't feather out completely but stops suddenly).
