How about those lenses labeled "Bokeh King"? Have a look at the price tags, carefully! (You have been warned..)opps.. sorry for my english.. its like very very very good like that..
(I haven't checked whether they all can be used with Canon systems, just to give your 'addiction' to bokeh and background blur something to chew on.)

Erm .. please check again: "bokeh" describes the quality of out o focus area. It cannot be achieved, it can only be good or not

Not the best photos I've ever taken but here is one. Here's another one. Both taken with my Olympus kit lenses.
You can see that there are parts of the photo in the background that are out of focus.
What's more, Olympus is reknown for having greater depth of field than brands with bigger sensors at the same f number. What more for Canon and Canon kit lenses?

For the first photo,
Olympus ZD 40-150 f4-5.6
119mm
f5.3
1/30s
ISO100
The last 2 pieces of info are not too important here. Note that:
1. f5.3 is the smallest f number avaliable at my focal length
2. 119mm is quite a large focal length- it is equivalent to about 149mm on your Canon crop frame lens (ie. zoomed in quite a bit)
3. The background is quite a distance away.
This contributes to the bokeh you see. You do not need a fancy lens. Neither must you buy Olympus lenses to acheive shallow depth of field.

hmmm i think i start to see the picture liao.. so i just need to make the background futher away and bring my camera closer to the picture? + all the setting?
honestly speaking, you asked that for the third time already. since you got that understanding, you don't need to ask anymore. Just go try it out. :bsmilie:

TS, stop asking, go shooting!!!
Stop talking on paper and just go out and shoot. You already known enough to start. You need to see the effects with your own eyes. Try with your kit lens first. Do it right and you can get nice OOF blur as well.

Very, very much agreed. It has been said many, many times. If I'm not wrong, links to Sulhan's notes have been given twice. I've already given you proof that it can be done with a kit lens, so yes. Go out there and shoot.
Unless you need a physics explanation too... :sweat:
Which can be provided, of course
Depth of Field: http://toothwalker.org/optics/dof.html and http://toothwalker.org/optics/dofderivation.html
Bokeh: http://toothwalker.org/optics/bokeh.html
But that's rather something for a rainy Sunday and requires some decent knowledge about Physics. Not the level of some Wannabe Education Channels ..

ok today i when to havey norman to try out 550d kit 1 lens.. really kit lens can do blur effect sia.. but idk why when i zoom in all the way i cannot make the aperture higher always stuck at F5.6 but when i zoom out to 18mm i can change make higher to F3.5! woot.. snap and got a blur effect bg! haha.. is there a lens that can zoom in and still have high aperture?
finally understand what senifer meant by.. You can understand it in 1 shot, SNAP! and you understand.
and it also could be after 60shots and you still don't understand why.

That's because the kit lens has variable aperture.
f3.5 is the smallest f number you can use at 18mm, f5.6 is the smallest you can use at 55mm.
f3.5 is the smallest f number you can use at 18mm, f5.6 is the smallest you can use at 55mm.

Can... spend MUCH more money on fixed aperture lenses...
go look for the f2.8 zooms, see if you wanna spend $2k plus on those lenses...

Just another thing to note, please get your terms in order: aperture cannot be higher or lower. Aperture is not the same as f number either. That is, f 5.6 does not mean the aperture is 5.6.
Aperture refers to the opening that allows light to pass through in your lens. Since it is an opening, it can either be bigger or smaller but not higher or lower
F number is inversely related to aperture. If you have a small f number, your aperture is bigger. By the laws of physics, this translates to a shallower depth of field, and not "bokeh effect".
Please stop using the wrong terms. Not only is it factually inaccurate, it confuses people who are trying to understand what you're trying to say.

What's wrong with the 1855? Why are you so concerned with bokeh?? PHOTOGRAPHY IS MORE THAN THE BOKEH.
