Hi All 
lurking for a while but my first post on this forum
I want to try macro shooting without buying a macro lens (yet!). So that means an accessory for my existing kit.
currently I use a crop body (Canon 450d) and I have three lenses:
18-55mm IS kit
24-105L IS f/4
70-200L IS f/2.8
EFII Extender x2
currently I get the best macro results with the kit lens (closest minimum focus distance)
but what should I buy to give me better macro with my the kit I already have?
- Extension tubes (Canon/Kenko)
- Canon 500D Close Up Lens
My current understanding is that extension tubes would work better with the kit lens and the 500D would be better for the 70-200.
But what would be better for the 24-105?
or which would be my best bet all round - extension tubes or 500D?
appreciate any advise
