Canon has had some really awesome lens rebates going on for a month or two, and back in December I caved and dipped into my mythical 5d mark iii savings fund to pick up some new toys. It had been a year since I had bought a new lens (I picked up a used 135L back in December 2010 as my last lens purchase), and I couldn't make it any longer.
I decided to buy TWO new lenses, the 180L macro and the MP-E 65mm 1-5x macro.
Here they are with my 100L for comparison:
And with the 1-5x fully extended:
I can't wait to take them out to Longwood and really test them out. I am going to have to get used to using my tripod for them though. I actually need to get some more quick release plates for them and a set of focusing rails for the 1-5x macro especially.
