Hello there, I'm new here and I would like to ask a question. I have a canon t2i and a 18-55mm lens, but i would like to experiment more with photography, so i would like to buy a lens, but wide angle lenses or macro lenses arent that cheap. Which lens adapter would you prefer me for my camera? I looked at dx.com and i found a really cheap wide angle +macro adapter.. Here's the link: 58mm 0.45X Super Wide Angle + Macro Conversion Lens - Black - Worldwide Free Shipping - DX . what do you think?
