View Full Version : HELP! Bad bokeh - I need some!

I'm writing an article (not Oly or Four Thirds specific) about the effects aperture settings can have on your pictures. Bokeh (de-focussed backgrounds) is in there and I thought I should show an example of bad bokeh. So I got an EC-20 converter and the much maligned 17.5-45 kit zoom and tried to create some bad bokeh. Even with this lens combination, it was actually quite difficult.

So I was wondering if we should see some examples of really bad bokeh that we've taken? :)

This is what I came up with:

I have definitely seen worse! :D

I'd love to help, but you simply don't get bad bokeh with Oly lenses...!

I do feel my beloved 50-200 non SWD coupled with the ec14 is capable of producing some strange backgrounds in situations like this.

This is just about wide open with this combination.

Hope this is the sort of thing your looking for.

Is this any help?

Zuiko 50mm f1.8 on Telplus macro converter, actually being used on an OM2

Or this?

Same lens but on a Tamron 2x teleconverter and extension tubes on my old E520

Ian,
Here are two images with strange bokeh I took with my E-600 and a modified Konica Hexanon 50mm f1.7 wide open.

John, that's cheating! Of course you will find bad bokeh on a Canon forum. Shame on you! *laugh

This is something that has occured with the 70-300 lens on occasions such as this (but it could be just shaky even with IS1).

'Bad' bokeh, not sure if as with all technics is subjective, but you may want to check these.

If you use a circular polarizer with an ultra fast film lens, all kinds of swirls and aberations appear in the bokeh. May also want to check out the shaped stuff, by shooting through vignette masks.

The ugliest Bokeh I have had


Oly-510 with 50-200 SWD and EC20 at ISO 400 minimum of Noise reduction
shooting distance probably in the order of 80 meter.

These are all difficult to judge, I think. Especially Flemmings last ones, where I would say the effect in is more that there is (for the lens...) just as great a distance between him and the bird as there is between the bird and the background, so effect looks more like a depth of field issue, noise and lack of detail, than bad bokeh.

Whether bokeh is good, bad or acceptable is so subjective. I often stop down when shooting birds, because I want a better depth of field on the actual bird, to get more of it sharp. Of course, I et less blurry backgrounds than I would had I used a wide open aperture. But if I don't I get only the focus plane sharp, and my taste is to get as much of the bird sharp and detailed as possible.

In Alan's monochrome of the rose twig, the lines of the background are perfect to accentuate the shape of the thorns, I love it! :D I'd say it's a perfect, matching bokeh. *chr

In this one (E5 and Zuiko 300 2.8 at f/4.0 1/1000, +0.3 EV, distance to subject 5 m), background twigs are identifiable as twigs, but I dont find them distracting, they just help place the tree sparrow in its environment. Others might find the background not blurry enough.
