This list is awesome, but it leaves out the most expensive and largest camera lens I’ve seen, the Canon 5200mm f/14 lens, which is currently for sale on eBay…
From PC Fastlane:
- Price: $11,999.00
- Product Page
- Weight: 10 lbs
Expect to sell a few organs to afford this thing. Price at almost $12,000, the Canon EF 800mm is designed for the pros among us. It will be released in May 2008, it is meant for long-range photography like sports, wildlife, and nature. Don’t expect to use this thing without a tripod by the way. At over 10 pounds, it probably weighs more than your camera. Thankfully, Amazon has graceously included free shipping with the item.
