| I went to the Official Canon website to look at what I need to take better macro shots. I never heard of them but I saw these called close-up filters. Has anyone every used these things? |

i have a set that i use on my 35mm.. they are not really 'magnification' filters... what they do is allow you to focus on somemthing closer than you normally would be able to... it reduces the minimum focal range of your lens...
someone correct me if i'm wrong here...

It is like sticking a magnifying glass on the end of your camera. They are focusing lenses that mount like a filter. About the cheapest way to get closer for macro focusing and give pretty good results with some distortion around the edges.

i have one of their macro filters for my canon powershot pro90 is. it worked really well, but was hard to get hold off in the first place. there are two different ones (D250 and D500 or something like that). check which one would be appropriate for your camera. the D250 is much more widely available i believe, i needed the other one of course.
all of the macro photos in my gallery have been taken with the canon macro-lens.

BTW, Those are great shots. Thanks for the info. Might be worth the investment. A couple of more questions, please bare with me. What extension tubes? Also, are there an affordable Macro lens out there that fits the Canon? I really don't want to spend more than a few hundred dollars.

i've never used extention tubes, but i believe they go between your camera and the lens and that way help you focus closer. there are probably other people out here that could answer that question much better. :)

Hoya, Tiffen and Cokin will all do close up lenses in a number of thread sizes. They often come in sets of 3 (+1, +2 and +4 diopters) which can be stacked. I know Hoya do a double element +10 lens.
You tend to get a very shallow depth of field with them. I use a set with a 52mm thread for macro shots on my Powershot A40.

| Extension tubes do go between the camera body and the lens. They allow for closer focus but you loose any automation so you have to shoot on manual with most. Close-up filters are good for low light because they loose no light (Extension causes a little light loss depending on the length of the tube.) Tubes offer greater flexability because they can be used on any lens, filters come in set filter sizes. Magnification = extension in mm / lens focal length. (ex. 50mm tube on 50mm lens = 1x; 50mm tube on 100mm lens = 1/2x) Tubes allow you to play with many combination. I also like to reverse a lens on extension for magnification greater than 1x. |
