I'm toying with a new lens... I had thought a fast macro that I could use for Astro, but I'm getting greedy on reading reviews etc to go for a prime astro lens, either the Canon 135 F2 or the Canon 200mm F2.8....
I've found an Australian importer who sells the 135mm for $1107... but they have the 200mm on special for $889. I'm sorely tempted.
What do you guys think of their relative merits at these prices... is 200mm going to be too restrictive on popular wider objects with the 40D sensor... eg Magellenic clouds?
Help me spend money
