Canon Macro Lenses. What are you using?

id say off. uv filter doesnt do anything to benefit a digital image.

you're only adding a cheap piece of glass that will degrade the image quality

consider using Kenko tubes on your existing lens. It shortens the focal length... ie reduces the minimum focusing distance so you can get your camera closer to the subject. Using these will decrease your f/stops though.

If anyone is interested, I could be convinced to sell my Canon 100mm macro f/2.8 (not IS). It's $650 plus tax when new in stores... my lens is mint, would accept $550 or a trade for a fisheye (Canon 15mm f/2.8 or Tokina Canon mount 10-17mm f/3.5).

I have this macro lens but am also quite happy with the results using kenko tubes on my 50mm f/1.2L or my 70-200mm f/2.8 L w/ IS, hence the 100mm macro is redundant.
