Consistent Bokeh?

Do all lenses from a particular vendor with the same aperture and regardless of the focal length, say Canon 2.8 lenses, produce the same level of bokeh? My experience with this issue is not conclusive.
Thanks for your input.

Under exact condition they should if all your camera settings are the same and the light and other variables do change. I found out is hard to get the results out side. Inside you can control the conditions more.

First of all, "bokeh" does not mean "out of focus." It refers to the QUALITY of the out of focus area.
What you are asking is if different lenses/focal length with the same aperture produce a smilier look to the OOF area. The answer is "sorta." If the subject is the SAME SIZE ON THE SENSOR, then yes, different focal lengths with the same aperture do produce essentially the same look. That bokeh stuff, however can vary a LOT. Because the quality of the OOF area is affected by the glass, the number of blades in the aperture, and to some smaller degree by the focal length. What WILL change is perspective as you move to keep the subject the same size at varying focal lengths.

Not in my experience - a lot of it depends on the lens construction. For example those lenses with fewer aperture blades (cheaper?) produce bokeh that is not as pleasing, at least to to my eyes.

Same lens, same camera same setting exact same light = same capture.
While you are able to get the first three again and again the last one is a bitch, even in studio.
Good luck with that.
As to what bokeh is... (a recurring theme)

There are some nice russian m42 lenses usually with preset apertures and have many blades with a circular aperture through their range, although some are not that cheap these days either.

Helios 44-2 58mm f/2 maybe? Would that be one of those? Quite inexpensive, 8 blades. Works just fine on my Zenit E!

Is that just a knee jerk reflex reaction? Although my 8 blade FL 55mm f/1.2 still seems to do OK....

Do ALL lenses from a particular vendor produce the similar level of Bokeh under similar conditions (setting, exposure value, etc)? In a word, no. ALL vendors produce lenses with varying characteristics for different markets and to fill different price/market nitches. So...not all "XFHYD"-brand lenses will produce indentical image results. THAT was the question you asked, JayHT, and THIS is your answer.

nice, I have one, fairly unique with swirly bokeh :) You know for a few dollars you can be using it on your canon with focus confirmation.

Yes, thank you. And I may one day. For now I still like it on my Zenit E. My first serious camera. And I do have my Canon FL 55mm f/1.2 on my DSLR camera with focus confirmation - Ed Mika conversion.

No. Even the same lens will display different bokeh quality with different distances and apertures. And not all fast lenses provide great bokeh, and not all slow lenses produce awful bokeh.
However, Leica lenses use good bokeh as an important characteristic particularly the older M screw mount lenses.

Here is an overview on lenses that have good bokeh that one photographer put together:

The Leica M mount is a bayonet.
