Ah, So thats what created the 'dreamy' effect in my latest macro shoots (3 Films). I liked it... because its macro and it's something you can't see in life with the naked human eye, it works with the dreamy effect. It's only noticable when zoomed in though.
Ah didn't realise I would be able to 'convert' a normal lens to a reasonable macro lens with a cheap additional module lens.
There's a cheap trick that you can use to get macro-esque images as well. Take any pair of cheap binoculars, remove their front lens elements and tape them together. Then take a 52mm filter (for your 28mm lens) break out all of the glass and use electrical tape to tape the two lens elements together until they will fit inside of the 52mm filter. Once finished then simply screw your new filter onto the lens and you have a macro setup. (It works significantly better if you stop down to about f/8 and use a tripod)
I have used this before to get macro shots and it worked surprisingly well. (
here is one shot that I took using a 50mm with that setup. It was only shot at f/4 so it wasn't optimally sharp and it was handheld which further lowered the sharpness, but it was pretty good I thought.)
Another way to get a cheap macro setup would be to take a wide angle lens and reverse it. Thus the front of the lens would be pointing at the camera and the rear would be pointing outwards. This works best with older lenses that have an actual aperture ring though, as you cannot stop down since the lens is not connected to the camera. (
here is an example using this setup with a Canon 17-40mm /4. I had to put the ISO to the max to get a reasonable shutter speed, so mind the noise. Although this setup allowed me to get six times life size, in other words it was six times closer than a dedicated macro lens would allow you to focus. Again not the best picture, but I don't often stray into macro photography, I'm just a gearhead

)
And the final cheap way to get a macro-esque setup would be to order extension tubes. They put distance between the lens and the camera and thus allow you to focus closer. There are two types of extension tubes, ones that have the electrical contacts and maintain the connection between the lens and the camera body, and those that don't.
Here is an example of the latter, that doesn't, it is very cheap and will allow you to get macro shots.
Here is an example of the former, which will retain the connection between the lens and camera, it is priced significantly more, so you'll have to decide if it is worth it for you.
I'd try those three in order, such as if you don't like the first, go to the second, then the third until you find the ideal setup for yourself within your budget. Hope this helps a bit
