If I shot this with an old Leica lens design the you might see a different effect moving from an in focus item towards out of focus. Old lenses are said to make that transition very smooth (so called creamy bokeh). A very modern lens is better corrected optically. That means that the change from in focus to out of focus can be more abrupt because it is reproducing the dot more accurately. Really, bokeh depends on a lot more than lens design. The distance from subject and your focus setting/decision, what is in the background, the aperture used , exposure decision etc etc. Other stuff also affects the shape of the out of focus points of light (other optical imperfections or aberrations). I can show you very different bokeh from the same lens. Just look at the photo again if you like. Look at the edges of the leaves and the little droplets in the out of focus parts. Taking the example of a round dot of light, neutral bokeh might show you an very even round area with fairly sharp edges, an old lens might show you much softer edges fading into the rest. An over corrected lens might show you a dot of light with a distinct ring around the edge. Most people don't like that. With a mirror lens you get donuts! With modern Leica lenses like the Summilux 50 ASPH and the APO Summicron 75 ASPH you can sometimes see the exact shape of the aperture blades like a cookie cutter. That bothers some people too. *If you want to take more interesting pictures, stand in front of more interesting stuff* -- Joe McNally Cheers Geoff http://www.pbase.com/hoppyman On 4 March 2013 13:53, <tedgrant at shaw.ca> wrote: > MONTE SAID: > >> CAUTION: >>>> >>> Contains Bokeh just for the bokeh of it.<<<<<< >> > > HI CREW. > Please explain where???????
