This is the second time I have had the privilege to shoot with this lens, and every time I pick it up I get excited!! The lens comes in the same rugged hard case, as all the “L” white fixed focal length lenses. Inside the case, over and above the lens is an additional foot to support the lens's use on a monopod, two straps, one for the lens and one for the case, a lens hood and the lens caps.
When you pick up the lens you can’t help but be impressed by the build quality. One thing that will surprise you is the size and weight of the lens. The lens weighs 3620g, just lighter than the EF 400 f2.8L IS II USM (3850g), but slightly heavier than the EF 500 f4L IS II USM (3190g). But, it is on par with the AF-S VR Zoom-NIKKOR 200-400mm f/4G IF-ED lens at 3275g without a built-in extender. The EF 200-400 f4.0L IS USM 1.4x Extender diameter is 128 mm and the length without the hood 366mm, making it shorter and thinner than the EF 500 f4L IS USM lens (146mm x 383mm) but slightly longer and much slimmer than the EF 400 f4L IS II USM lens (163mm x 343mm). What is very nice about the size of the lens is that it fits easily in any carry-on case, and the days of fighting with the airlines about carry-on luggage is over!
