Congratulations!
you will love it
.

I saw on the other thread that your lens is sn 0000044. Camera Canada got mine from canon last week. Its sn 0000052. There must be more than that number produced by now?

3120000052. i thought the first numbers were a model designation but now i am curious.

the interweb says the first 2 numbers are a date code. 28= apr 2015, 31= jul 2015. the third number is the version "2"

afaik the rest is the sequential serial number. i just have a hard time believing that there are that few of these lenses being produced.

I've got #49.  Been trying to write a review of just the lens for BIF shooting, but I'm finding it difficult to separate lens performance from body performance. Most of my shots so far have been on 7D II with 1.4 x III. For BIF, the AF hit rate on this combination has been OK, but not as good as I had hoped for. At some point I will have some 5D III shots for comparison. Still shots are almost always great. I need some more experience with the lens to finish the review.

Hi candc,

thanks for the info. the 28 makes sense for my lens as I got it May.
Indeed, it is puzzling to think that so few of these lenses are made.
I have read an article that the double DO elements need to be perfectly matched and that apparently is a "manual" job.

Anyway, I love my 400 DO II and I am sure that you will be pleased as well

I have an old 7D mark 1 and for BIF with this lens it is far from perfect, some people would use other words to describe it.
Having said that, the 1DX with 400 DO II works great, even with the 1.4 extender. Using the 1DX with 2.0 III extender is not practical for BIF

My serial number is 240000047. I got it in December 2014.
I am using it on a 6D with a 1.4 III extender when I photograph wildlife.
It would seem so far that 400 DO II owners form a very small club.

2 more just for fun. these are the tamron 150-600 at f/6.3 and f/8. the tamron looks really good especially considering the cost difference. of course it is slower aperture and does not have the af performance but shows that you don't need to spend thousands on a supertele if you can live with its limitations.

yeah the quality is really good, but looking at the 600mm II photos, man that's amazing.

I finally got my cash together to get my order in for one.  I have been using the Sigma 150-600C.  It's great value, but I find I want to stop down to f8 to get any decent sharpness, and then if I crop ..... well let's just say it's a great $1000 lens for the range.

Anyway, I have a 7D and 5DIII and was hoping to use this with the 7D mostly, but I guess I'll have to see how that works out and whether I'll also end up needing to get a 7DII.  I guess if the IQ with a x2 is not that great, the f8 on the 7DII might not be all that useful.  Maybe it will be good enough for me for perched birds.

I'm not getting a 1Dx.  But if I'm spending $7k on a lens, what's another $1500 on a camera, right?
