My last photoshoot of the Blue Angels practice convinced me that I wanted or needed a zoom telephoto lens like the 100-400mm f/4.5-5.6L IS II. It will be considerably lighter carrying a single camera with the 100-400mm lens than to carry a pair of cameras with a pair of my lenses (70-200mm f/4L IS, 300mm f/4L IS and 400mm f/5.6L). Additionally, although I can shoot at higher speeds when using my 400mm f/5.6L, I would like Image Stabilization for shooting propeller aircraft so I could shoot at lower speeds not to freeze the propellers. The Mode 3 on the 100-400L II seems like it was designed for my purposes. Finally, the 100-400L II has a shorter MFD than my 300L or 400L.
The best price I could find for that lens (from a dealer whom I know as reputable) is $2099 (all prices in U.S. Dollars) after a $100 instant rebate. I did see a couple of cheaper prices but, they were from dealers that I do not know.
When prices are significantly cheaper than B&H, Adorama, or 17th Street Photo, something is amiss. I chose Adorama (all of these vendors offer free shipping and no sales tax (which amounts to a whopping $167.92 for someone living where I do).
Adorama offers an "accessory bundle"
77mm Filter Kit (UV/CPL/ND2)
FocusShifter DSLR Follow Focus & Rack Focus
Cleaning Kit
Capleash II
Flex Lens Shade
Pro Software Package (Includes Corel PaintShop Pro X7 & Corel AfterShot Pro 2 & Nuance OmniPage 18 & FileCenter Standard 7)
Normally, I never consider that type of "bundle". However, the price of the lens WITHOUT the bundle is $2099 and the price of the lens WITH the bundle is $2099. That is a no-brainer for me. Even though the filter package is probably junk, I can sell it for a few dollars and a couple of the other items like the Flex Lens Shade and Software Package interest me. I can play with the Flex Lens Shade (Adorama supplies all of the standard Canon gear such as the Front Lens Cap E-77II, Rear Lens Cap E, ET-83D Lens Hood, LZ-1326 Protective Lens Case. and Canon 1 Year USA Warranty) and I can give the Paintshop Pro to one of my volunteers who is starting to do a decent job photographing our rescue dogs in the Los Angeles area.
The final thing that swayed me to the 100-400 (besides wanting a single lens with that focal range) is that the ET-83D lens hood has a lock and a door to access CPL filter rotation. My 300L and 400L lenses have retractable lens hoods which I do love because it is easy to access my CPL filters for rotation. The door should make it as easy to access the CPL with my new lens...
I purchased this lens using PayPal credit and will be able to sell my 300mm f/4L IS and 400mm f/5.6L lenses before I have to pay for the 100-400L II. The combined used prices of these two lens will greatly offset the price of my new lens.
I was going to rent this lens but, $76 for four days rental plus one way shipping (I think) is pretty expensive. Especially when I am sure that I want this lens....
