Bokeh is closely related to DOF (Depth of Field).mazeppa26 said:wads the biggest f stop (thats means up to which f) or smallest APErture necessary to haf bokeh effect?
Correct. That's why I'm saying: "Less DOF means --> higher chance of getting bokeh."darrelchia said:do note. Bokeh is NOT blurred background, or shallow depth of field and should not be used interchangeably. This is a common misconception that new photographers have.
I'll leave it to you guys to do your homework and figure out what's bokeh.

everything also bokeh

You will never get any bokeh if your image doesn't have blur portion.
If the whole frame all sharp (in focus), can you get bokeh?Snoweagle said:That's what i'm trying to say, at any aperture u still can achieve bokeh but depending on how far away is your subject from u and how much you zoom.
tsdh said:If the whole frame all sharp (in focus), can you get bokeh?
That's right. Therefore if somebody want to get bokeh in his/her photo, he/she must create a photo with some blur portion. So he/she must know how to create a blur background, or in other word; must understand what DOF is.Snoweagle said:If everything is sharp, let's say infinity focus, there won't be any bokeh at all. Usually this is achieved by taking distant objects.
tsdh said:Diaphragm blades is just half of the story. It only determines the outer shape of bokeh (whether it is pentagonal or hexagonal or round).
But the most important factor, is the lens design.
A ring-shaped bokeh will still look bad even if its shape is fully round. And a lens with that kind of bokeh, can not produce a smooth background blur with blending colors, although it is usually able to produce very sharp image.
This is one of the properties which is emphasized on a "portrait lens". (bokeh will be mostly important on portraiture and macro photography).
Based on my experience, Leica lenses have excellent bokeh. Generally, german lens designers are very particular with bokeh, thay pay attention in correcting the spherical aberration. For Nikon lenses (I'm a Nikon user, so I only know about this brand), only the three portrait lenses have praisable bokeh: 85mm, 105mm, 135mm.Snoweagle said:Yes, only these 2 fields are especially important when dealing with bokeh. For portrait lens i think the 85mm has the best bokeh, even the 50mm f/1.4 is very gd.

Nikon also produced 105/2 DC, with spherical aberration control to alter the amount of blur (they call it "Defocus Control"). This lens is purposely designed for portraiture.
Nikon has 2 AF-DC lenses. 135/2 and 105/2.tsdh said:Based on my experience, Leica lenses have excellent bokeh.
