I actually do not own a macro lens!
May people dont believe me when they see all my insect close-ups but it is true.
I use a simple macro converter (image below). I got it for a gradutation gift but I checked online and you can get one for your DSLR or copact DSLR through eBay from $50-$200!
The majority of my insect and flower pictures were taken with this converter and it works perfectly! The only issue it that it sometimes created a blurred edge as it is literally a magnifying glass. I'm hoping to invet into a macro lens very soon, they cost aroung $500 for one. :L
