Not really Martin, good it isn't always black and white but some lenses clearly have a better bokeh then others.

From here link

Fig. 1. Poor Bokeh.


This is a greatly magnified blur circle showing very poor bokeh. A blur circle is how an out-of-focus point of light is rendered. Note how the edge is sharply defined and even emphasized for a point that is supposed to be out-of-focus, and that the center is dim.

Fig 2. Neutral Bokeh.


This is a a technically perfect and evenly illuminated blur circle. This isn't good either for bokeh, because the edge is still well defined. Out-of-focus objects, either points of light or lines, can effectively create reasonably sharp lines in the image due to the edges of the sharp blur circle. This is the blur circle from most modern lenses designed to be "perfect."

Fig. 3. Good Bokeh.


Here is what we want. This is great for bokeh since the edge is completely undefined. This also is the result of the same spherical aberration, but in the opposite direction, of the poor example seen in Fig. 1. This is where art and engineering start to diverge, since the better looking image is the result of an imperfection. Perfect bokeh demands a Gaussian blur circle distribution, and lenses are designed for the neutral example shown in 2.) above.

Thank you Bob didn't knew those things exist, they look handy.
Wished they had a readout screen so that you can see if it went alright and things like that, just like you said.

SDHC certainly are becoming cheap but still they are for more expensive then and harddisk or USB-stick so that's why it might be an interesting option.
Certainly whit movie mode on the camera it might go quite fast with storage room.

Why did you chose to crop it while you liked the full-frame better?

I like them Amin, now get the composition right and you have it

This is as good as a comparison as it can get between the D60 and K-M I believe link
SRS also has new lens hood £27.99 link
Although you can try to make a deal with the normal DA 18-55 II lens instead of the L version

Thank you Barrie just what I was looking for, now trying to find out what the contact does

Just looked at the back of the DA*50-135 and it is the same as the TC back!

Rear of the DA*50-135



Rear of the DA 17-70



DA*55



DA*300



From which lens did you took the photo Barrie:
Also your contacts look silver while these and mine looks gold.

Here is a read link
As you can read John proves he is also human because he is not right for once
Bokeh isn't effect by the number of blades since that only defines the shape of the blur circle but not the distribution of the light in that circle and that's what bokeh is all about.

Sorry to go off-topic now but someone is selling a relative new K200D for £200 on the Classified Adverts section of this forum.
It's a camera with a bit more features then the K-M, weather sealing 9 points focusing and indicator but it's a bit bigger and has another menu structure I believe then the K-M but better match against the Nikon D60.

Someone else is also selling a lot of his lenses so if you're quick you can get a nice kit for minimum amount of money.

Maybe not your intention to buy secondhand but it is something to consider.

Was almost 4 hours sooner then you Dan

Very amazing what things they can think up too fool your mind
Makes me wander how much and how we look at a photo.

Thank you Bob,
I believe we have BBC4 on the telly here so will try to see it.
