[time1985]

I am looking at cheap options for macro photography.

Currently I have a Nikon D200 with an 18-200mm lens and a 50mm f/1.8 lens.

I am looking at Zeikos ZE-CU472 close up lens attachments to mount on my 18-200mm lens.

OR

Reverse mounting my 50mm lens with a BR-3 from Nikon.

- Do either of these affect the aperture?
- Would either cause a vignette on the image?
- Which is better?
- Are there any other methods or products which you can recommend?
