Maybe if I had more money than I knew what to do with, or had regular paying work in a very specialized field (like stealthy photographs of something a mile away?!?), I could see buying one of the twenty or so 1200mm Canon L series lenses in the world. B&H Photo currently has a used one for sale. I didn’t even bother checking the price, though. I know it will be more than my car cost me.
Here is a review of the lens, in case you wanted to dream about it:
*** update: Curiousity got the best of me. I looked up the price on the used 1200mm lens. I figured it would be around $25k. Nope. You want to buy that lens? Get ready to put down $120k in cash!!! Yikes!!!!!
