These are the type of reactions I get whenever I mention the word Bokeh, even to seasoned photographers!
So what is this bokeh, then?
Well, it’s kinda like a new-age techie word that’s been added to the English language.
In the main, bokeh is that part of a photo that is out of focus. So, if we take a shot of, let’s say, a flower, and use an aperture something like f2, then the flower will be in perfect focus, but the background will be blurred…in this case, an excellent situation, as too much background information would detract the eye of the person viewing the photo from the main subject, the flower.
But bokeh alos depends on the lens you are using…some newish lenses may not have much bokeh, whereas older lenses may have much more.
The best way to judge if an accessory lens has good bokeh, is to look at the aperture blades inside…..modern lenses usually have 6 or 8 blades, but older lenses for classic film cameras may have 12, 14 or more blades.
An example of these classic lenses are the old Prinz Galaxy lenses and the Pentacon 135mm f2.8 versions. Both these lenses, and others like them, will give you beautiful bokeh…if you want it, that is!
