Looks big and heavy but it stops at big! Believe it or not, this lense really is not as heavy as it looks. Granted I shoot with a 70-200 f2.8 and 85mm f1.2 often and I am used to heavy lenses, but this is my first large lens and I am surprised to see how easy it is to hand hold this lens. Since it is already dark outside, I have been playing with the lens indoor and quite impressed with the focus speed. Even when the focus setting is set to full range, it doesn't hunt for long and provides creamy bokeh almost instantly.
IS is very quiet (I tried but can't hear it yet), I am able to snap pictures at 1/15th hand hold with indoor lighting!
Lens comes with nice case that is a decent size for travel.
Going to give it a full review in few days. So far so good!
UPDATE 1 after about two weeks of playing with the lens:
Focus is extremely fast and quite. It takes time getting used to shooting at 400mm. Make sure you have a need for 400mm or you will find yourself annoyed that there are not much day-to-day need for a lens of this caliber. If you do find yourself needing a 400mm, you have found the one!
It is light weight, solid construction just like all other canon L series but even a notch higher. It feels extremely durable. Picture quality is just amazing even wide open. I haven't quite seen a difference when stepping the lens down to 5.6 or more. The amazing distance and sharp focus of this lens, makes subjects pop out with no effort. IS is very very effective with multiple modes. So far I have not tapped too much into the two new fancy modes but the normal IS has helped me take pictures of any situation I have tried so far.
When using with a canon 2x Mark III extender and Canon 5D Mark II, I lost autofocus even with middle point. I will try to update to latest firmware to see if it supports F8. Manual focus at 800mm is a fun exercise and will take a ton of practice but you have a telescope in your hands that you can handhold!
Be advised when taking photos of items far away (more than a mile), you are condensing a ton of particles and junk, at first you may be disappointed at the quality of the pictures only to find out after a windy/rainy day with super clean air that lens proves to be very sharp.
Color saturation is excellent, I give it a 10 out 10. My 70-200 gets a 9.5/10 and my Canon 85mm f1.2 gets a 9/10 on colors.
Bokeh is creamy with nice circles of light as opposed to polygon. Try a green background and you will be amazed with how the subject stands out and how colors come to life. (Birds are perfect for this - See https://www.flickr.com/photos/bigmaster/16399421956/).
Since this the first review of this lens, I will continue to update it as I go...
I will enjoy this lens. Just a tad expensive but able to use a big lens even handheld since it is so light weight compared to its size.
Update: Now had this lens for almost two months and really love this lens even more than original review. I look at some photos with this lens and looking back at some taken with my old 100 - 400 Zoom and the zoom all has a little softness to them I hadn't noticed as much until I got this lens and now can see the softness of my zoom lens that this lens is so very sharp and was reason I wanted it and hoped I would get with this lens. It is very sharp and lightweight that I can shoot handheld with the right settings and come up with some really nice shots. Adding another photo of a deer taken a few days ago and it looks great with clarity and resolution that my old zoom would not have produced in equal quality. I took a few of the moon and even with a 2X extender, it came out quite sharp with no noticeable softness with the extender. I really love this lens. Also knowing this lens came from Adorama helped me with purchase as they are a quality camera store and still able to buy from Amazon.
After working my way thru approx. 300 RAW pictures
taken with my Canon 7D MK II in combination with this
lens and the Canon 100-400mm L IS MK II, Tamron 150-600mm
and the Sigma 150-600 Sport, I found out that I, in general, agree with
the findings at:
Especially the findings regarding how it works with the Canon MK III extenders.
At the indicated, not the true, focal length of 400mm, the difference in resolution between my Tamron 150-600mm, my Canon 100-400mm MK II,
my new Canon 400mm f/4 DO MK II and a borrowed Sigma 150-600mm Sport, was of no significance to my photography. (that is, birds, butterflies and dragonflies, for the latter two I use my Canon 100-400mm because of its superior min. focal distance)
Looking at the contrast the Canon lenses came out on top. Looking at the other main optical parameters, not that important to me, the Canon 400mm DO came out on top.
Best performance at 400mm for the Tamron and the Sigma and the Canon 100-400mm occurred at f/7.1 to f/8 and for the DO lens at f/5.6.
At 600mm the Sigma outclassed the Tamron, both worked best at f/8.
But the Tamron has a great weight advantage, which to me, is a greater
benefit than the loss of sharpness above 450mm.
I preferred the Canon 400mm DO at 560mm and f/7.1, and also at 800mm f/8 (with Canon extenders MK III 1.4x and 2x) to the Sigma at
600mm f/8. (cropping) And this, please note, before I added the benefit of Canons superior stabilizing , better autofocus and the big weight advantage.
I like to carry the lens (in use) in its foot with a loose strap for extra
safety. Tamron has a good foot, the Sigma not so good, to short
a distance between the foot and lens body.
Both foots on the Canon lenses are to short for a good grip,
so I replaced the original Canon DO foot with the one Canon uses on
the 400mm f/2.8 and the 200-400mm f/4. Perfect fit and grip with good balance even when using the extenders.
In the end, when on foot in nature, size, weight and handling are the main
parameters, if not the only, in my world at least, that matters.
And for that purpose I could live with the Tamron, its a very good 150-400mm lens with an extra gear.
The Sigma is a good lens superior optically and mechanically to the Tamron, but too heavy to carry around in order to take photos on the fly.
Canon 100-400 MK II is, of course, the Sigmas total antithesis when it comes to handling, not to mention autofocus and stabilizing, and it can be used with the 1.4x extender.
Canon 400 DO MK II is as easy to carry around for prolonged time as
the Canon 100-400. Its the perfect lens for birds in flight, and has
the advantage of working surprisingly well with both extenders.
Its not always, when on the fly, possible to use the Tony Northrup
extender. This excellent extender is cheap and has an outstanding
optical quality. Does this extender exist ? I hear you ask ! Of course
it does, its your feet, move closer !
But when the Tony Northrup extender is not available, the next best
thing is, as I see it, the Canon 400mm DO MK II with/without extenders.
