Pros: Fast auto-focus, Superior build quality, Super-sharp images, very verstaile telephoto range, built-in teleconverter
Cons: on the heavy side
Best lens I've ever used for aviation photography. All of the versatility needed to capture images in any setting, and the built-in converter loses almost nothing I can detect in terms of image quality or focusing speed. Extremely sharp, extremely versatile, and built ruggedly for travel to rugged places.

Pros: Superior build quality, Super-sharp images
Cons: expensive, heavy
This is the finest lens I have ever owned! It is lightning fast and crisp and the 1.4 extemder transition works brilliantly. It is heavy so I recommend a GITZO 2541 travellers tripod with the lightweight Acratech Ballhead. It is such a gem that I carry it in a Think Tank Glass Limo backpack!
The uses are nature and sport photography but I have used handheld for neighborhood shooting!
I cannot wait for winter shooting with my 1DX - Churchill, Canada and California Birdlife.

I took delivery of the new EF 200-400mm f/4L IS USM Extender 1.4X three days ago. First impressions out of the box were exactly as I expected. From the workmanship of the lens to the case and accessories, the quality is Canon’s finest. Having worked with the 600mm, the size and weight were as expected. Though I have taken a couple dozen handheld shots resulting in tack sharp images, you will need to use this lens with a tripod or monopod.
I am using the 5D Mark III body. From 200-400 the image quality is extraordinary. Even flipping the 1.4x into position and noticeable degradation is extremely minimal. I am impressed with the quickness of the autofocus and have been using the stabilizer in the on position while tripod mounted with excellent results. I find the various control switches to be easy to reach and operate, even without looking. The 1.4 lever is positioned in a natural location for my finger and has a wonderful feel. I can easily flip the lever while tracking an eagle in flight without missing a beat.
The lens produces a beautiful bokeh, as does the 600mm. Far more pleasing to my eye than the 100-400mm does. My reason for purchasing this lens was the versatility is gives me while shooting birds and wildlife. My one and only disappointment would be that the lens does not autofocus with an additional 1.4x extender attached if the internal 1.4x lever is engaged. The only saving grace is it does autofocus with the internal lever in the off position and once focused, you can flip the lever and it remains in focus. As I don’t intend to add an extender often, this is not of huge concern, but people should be aware of that.
My view on the cost of the lens is without complaint. It is a major investment, but when you look for a tool to do a job, cost is secondary. When you pay less you typically end up with a tool that does not meet your expectations and with that, you’ve wasted your money. The cost to manufacture this lens has to be amazingly high. Thus the cost is passed on in the selling price. If you are fortunate enough to be able to afford one, my opinion is you will find it to be an extraordinary tool to add to your gear.
