If you don't already know why it's a good idea, then it's probably a bad idea..
What is it that you're trying to achieve? This is a very specialized converter...are you aware of how the 500D affects your lens?..
Sorry I have no idea how it affects this expensive lens?Please explain.I am thinking of gettiing this instead of a macro lens.But if it is not good I will buy a Macro lens.Thank You..
The close-up converters limit you to a narrow working distance. The 250D has a working distance of 165mm-250mm (6.5"-10") and the 500D has a working distance of 300mm-500mm (12"-20"). Within these ranges you use the focal length of the lens to determine the amount of magnification. So you zoom out for a larger field of view and zoom in for a smaller field of view. The greater the zoom on your lens, the more magnification you get. With a 200mm lens I believe you will get somewhere around a 2" field of view..
Your question will probably be better answered in the Nikon SLR Lens Talk forum. But before asking, go to Yahoo and search for:.
Site:forums.dpreview.com 500D Nikon.
Just copy the above and paste in the the search window. You'll get a lot of links to discussions in this forum on the use of Nikon lenses and the 500D. Read up, and if you still have questions then ask in Nikon SLR Lens Talk..
I am thinking of getting a Canon 500D 77mm Close Up Lens.To use with my Nikon 18-200 vr lens.Good,bad idea?Thank You.
I have no idea why Graystar is being so negative about your question, it looks pretty sensible to me..
There are three ways to take very close up shots, down to 1:1 macro and beyond..
1) Extension tubes.- Work best with prime lenses.- Lose infinity focus.- Can lose up to two stops of light..
- Difficult to use with zoom lenses - effect varies with zoom, and focusing can be strange..
- Some lenses can't use extension tubes because the plane of focus moves inside the lens!.
- Optically pretty good because there is no glass, but you are using your lens beyond it's design limits so be prepared for distortions and/or aberrations..
2) Supplementary close-up lens.- Works well with zoom lenses.- No light loss.- Working distance is very good..
- Range of working distance is very limited - 500 mm is the *maximum*; minimum depends on your lens but say 300 mm..
- Can sometimes achieve 1:1 - e.g. I get approx 0.9:1 with my Canon 70-200 f/4L plus 1.4x TC plus 500D close up lens..
- Can use the zoom to change magnification (and you will need to, as you can't move further away).- The 500D is optically excellent.- Remember that the 500D is designed for longer lenses - over 100 mm..
3) Macro lens- Most expensive solution, obviously- Yet another lens to carry - Most can't achieve the working distance of the 500D at 1:1- But in every other respect this is the best solution for general use..
- This is the only solution which will allow you to move directly from macro to infinity focus without rearranging hardware..
I have a set of Kenko extension tubes which work well with my 50/1.8, and a 500D which works equally well (for different applications) with my 70-200, with or without a TC. I used to have a Canon 100/2.8 Macro, and plan to buy another soon. So I practice what I preach ..
I must confess I'm missing something. Do you have both a Nikon and Canon camera; if not, one of the two lenses won't work that well on your camera body, which ever one you have..
Macro lens are the way to go. Most expensive and best are the Nikon and Canon macros, second best but still very very good, Tamron 90 available in different mounts, and last best for budget poor person is the Vivitar 100 (out of production) but you can pick one up cheap..
Check out the macro thread that occurs very frequently in the Canon lens forum, and follow some of the links that are offered under the original poster, these links will help you to get going...

1st: The Canon 500d is a HIGH QUALITY Close up lens that is attached to ANY BRAND lens with the proper thread and or thread adapter.
2nd: As long as the 500d Closeup lens is used within the proper recommended FL of the lens used..the results will be fine..
3rd: Yes, you ARE missing something....the Canon 500D IS NOT a Lens that attaches to the body...IT ATTACHES to the FRONT of the lens...SO ANY brand lens can used with it !! As long as you get an adapter to attach it to your lens filter threads..
