Thanks everyone for posting good examples.  I am getting a feel for it.

That's a bad advertisement for Pentax!

Your Canon bokeh trumps the Pentax bokeh! That is a brilliant bokeh effect!

Very good example

Anybody can claim "good bokeh" when the background is completely blurred and you can't see any features at all. In your case it's still obvious that the background highlights are circular, but the edges of those circles are indistinct. It is, as you say, creamy.

Re: Question: Bad Bokeh / Good Bokeh

Thanks Simon,

The idea was not to compare among  two brands, but rather to show different types of bokeh s a results oif using different technologies (FF and cropped modes)

This is when the differences between FF and APS-C become really significant.  The FF allows a better separation from the background given a narrower DOF. It's really striking when shooting wide open.

But still the Takumar 55 and Tamron 90mm also produce a pleasant bokeh iusing the k-5.

Ah I see, now I see another reason for the pandamonium for a Pentax FF!

I think I'll buy some film and try my Pentax s1a out then. I don't have macro lenses although I do have a Vivitar 28mm close focus, CZ 50mm Tessar and Helios 44-2 which I think all focus pretty close.

Do lenses focus closer on a full frame than a crop sensor?

Re: Question: Bad Bokeh / Good Bokeh

The sensor will not matter to the focus distance in the slightest. However a smaller sensor will appear to have a greater magnification due to the crop factor.

Very smooth, but what's with the purple fringing in the center of the flowers? Oh...ah...never mind.:-D

Wow, more than the bokeh what I like here is the 3d effect. Was this taken with a Zeiss ?

When your potentially looking to use the out of focus area's of the picture as a more active part of the composition I think there rendering becomes much more a matter of taste.

Yes, bokeh is more a matter of taste. And depends on the situation, on the object and how the photographer wants to express a visual message - I think

I shot this last year for example with my old Canon 35mm f/2 rather than my 100mm macro because I wanted the busier bokeh and the pentagonal bokeh balls to match the "spikiness" of the frost on the grass.

Very good example how to use the lens - and bokeh.

Bokeh OKish but still way too distracting

Hi again. I'm just curious about opinions of the bokeh in this picture. Trying to get a general feel about what other people like. Do you like it, or not? If you like it, why? And if not, why not? It was shot at f 4.5, so the straight edges  of the aperture blades are visible.  Thanks for your input.

Mark

for my taste:

- the quality of the bokeh is ok-ish at best.  As you've mentioned yourself, you see diaphragm blades and the resulting effect is really not very pleasing

- more importantly, even the out of focus white flowers, distract the eye massively from the flowers which I assume to be your subject

Bottom-line:  before you have a bokeh issue on this shot, you have a much bigger issue with colour composition (yes I know that white isn't strictly speaking a colour)

Re: Bokeh OKish but still way too distracting

Here is a test shot of some artificial flowers stuck in my gate. The reason I call it a test shot is because I acquired this M42 screw mount Vivitar 28mm f/2.8 lens as part of a dusty job lot.

It had slight fungal growth and the aperture ring didn't work. I took it apart, cleaned it and fixed the aperture ring and it looks not too bad to be honest.

Anyhow there are different types of bokeh going on in the background.

Re: Bokeh OKish but still way too distracting

Well here's a harsh example from a lens (DA*300) that IMHO has pretty good Bokeh, but I guess you can overload a background with highlights.

... and I should say the longer the lens the easier it is to create a smooth OOF.

One lens I choose for a wider fov, Zeiss Distagon 25mm f2.8

As others have mentioned the Helios M44-7 can produce wild Bokeh with a swirl to it

But this is controlled by the depth of field and proximity of subjet as it can also be buttery
