Some may feel that this lens is a tad pricey but many forget about the needless things in their life that they can sell in order to purchase this beast. I immediately sold my vehicle because I was finally able to convince myself that I only use my vehicle a couple hours out of the day. It was sad that I even had to contemplate selling my car for this camera attachment but to somewhat justify my hesitation in selling it, I do drop off my children at school and use it as transportation to and from work every day. So, once I sold it, I realized that I had to come up with another $21,000.I tried selling my apartment, but my landlord indicated that I could not legally do that. Whatever, Jim (Because I have learned not to burn bridges from past experiences, I stopped having open houses. Plus, the lawyer and court fees would put a damper on my upcoming Amazon purchase). Where was I going to come up with this $21,000? That's when a Sigma light bulb went off in my head.I sold my two children to the Pesticide & Insecticide Testing Corporation. I feel it was a solid move on my part because they explained that my (now their's) children would always have enough to eat, exercise every day, and have a doctor present 24/7. With the money I made with this no-brainer sell and the under-the-table cash my wife was getting from working on the prestigious corner of Main Street and Almond Street, I was finally able to make the purchase of a lifetime.I even had some extra cash leftover, so I decided to buy my first digital camera. This green monster looks great on my brand new Canon Rebel XSi. Thanks Sigma!
