Just to start this off, I bought a replacement lens foot for my copy of this lens, a LP-59N from Kirk Enterprise Solutions for when I might use it on a tripod

I have recently added a 1.4x iii extender to my kit and used it quite alot whilst on my recent trip to Mull, their didn't seem to be any noticeable slowness in the autofocus on my 7dmk2, so I am contemplating the purchase of the 2.0x iii extender with the 400 DO mk2

One thing I have noticed about using the 400mm DO mk2 prime is the getting used to not having a zoom like I did on the sigma 150-600mm C lens, so its a bit more about re-composing my shot and more use of the focus points and moving them to suit.

I have been using my 400mm DO mk2 wide open lately at f/4.0 and I have to say it is sharp, used it like this on my recent trip photographing bears with saker tours, here's a close up of a female bear Carpathian Brown Bear (F) Hungary 1 (1 of 1).jpg

....Okay, I don't have a 400mm DO but can offer you my opinion that the 2x III Extender works extremely well on Canon's version II prime telephoto L lenses < In my case the 500mm F/4L II. Here is a link to my album on Flickr to form your own opinion about the 2x III :

https://www.flickr.com/photos/114775606@N07/albums/72157685377629534

I have seen excellent results with the 2x III on Canon's 300mm F/2.8L too. Also on Canon's 600mm F/4L II.

When I was considering buying a 400mm DO I would not have done so without also buying a 2x III. In the end I went for the 500mm as I already had the 100-400mm (which doesn't take the 2x well) which works well with the 1.4x III.

I hope this helps.

Now that Canon have released both the 400mm and 600mm F/4L III which are much lighterweight, does this mean that the 600mm DO will most likely never appear?

I realise that such questions can only be speculation until Canon make any official announcements.

Robin thanks for the info and link to your photos which I will have a look at at some point, a little update is that I am going to upgrade to a 5dmk4 to benefit with the low light performance and use of higher ISO, with this in mind I will more than probably get the 2x iii to use with the full frame body.

....I have had a 7D-2 since they were released in the UK and have used the 2x III on it. Also, my first full-frame body was a 5D-4 and so I have used the 2x III on that too < Both on my 500mm lens.

I have subsequently sold my 5D-4 in part-ex for a 1DX-2 but have found that although both FF bodies offer less 'reach' than the 7D-2, the FF bodies offer slightly better image quality. The 7D-2 is far from shabby though.

Robin can you tell us how the 2x ext presumably iii,preformed AF speed wise, with the 7Dii and 5Div compared to the 1dxIi please. I'd personally value your opinion,but I also think it might help Martin,which is more important to me,given i've made my choices

Martin you need that 2Xext in your bag ,it;s a no brainer it's only hundreds of pounds rather than thousands and it adds so much to your. focal lengths. The 400 DO IS ii takes these ext's so well. Sure i'm still getting to grips with it all,the biggest issue for me is shooting at f8 in blighty in the grey, But that said these new sensors help a hell of alot. I honestly wonder whether the 1dxii might be a better choice,even if you go second hand UK stock or grey. The weightis the only negative I can really see. i'd love to have a 5div aswell for the extra pixies,but the DXii is one hell of a tool,prices are dropping and also black friday isn't so far,good deals there from Canon last year mate,might be worth waiting to see wha's on offer

All the luck bro,bear portrait is lovely...ha ha primes really make ya frame don't they,it's hard but a good disciplin to master.........you can see why I moan so much about my own failings up close,but I have to learn this,it's imperative

all the luck

....Yes, firstly it is quite important to use the version III Canon Extenders as they play very well with the version II (and now III) white L lenses.

The following information I am giving is not based on anything remotely scientific but is merely how it feels to use and the results I personally find acceptable. AF is slowed down when an Extender is mounted and that's primarily due to the maximum aperture becoming smaller and consequently (broadly speaking) the sensor reading from less light input < This of course varies slightly because of the camera body's capabilities and, as Stu suggests, the 1DX-2 currently performs the best. It is afterall Canon's flagship.

AF feels slower when in AI SERVO and tracking than in ONE SHOT. The 2x feels slightly slower than the 1.4x AF. But it also depends on light and speed of movement and doesn't always matter to the final image result.

If your Canon L lens has the option, if you switch to Stabiliser Mode 3 then IS is off while you are shooting and is only actioned when the shutter is released. This works best if you use Back Button Focus. The reason it slightly, not completely, counteracts the reduced AF tracking speed is because the IS motors aren't permanently in use and hence requiring more from the processor. Having dual processors is yet another reason why the 1DX-2 performs better than a 5D-4. I find that the 5D-4 and 7D-2 perform AF very similarly but the higher fps rate of the 7D-2 gives the impression that it nails more shots.

Some lenses take Extenders better than others. For example the 1.4x works very well on the 100-400mm F/4L II but the 2x kills AF. My 500mm F/4L II takes either well and I have been surprised how well it takes the 2x III < Check out 'THE 1,000 COLLECTION' Album on my Flickr page. The faster F/2.8L lenses (none of which I have) should perform even better.

Btw, having had a 5D-4 with more pixels than the 1DX-2 has, I haven't missed or even been aware of those extra pixels < However, I don't print my images. The image quality of the 5D-4 is more noticeably better than the 7D-2 but the 7D-2 ain't shabby.

I agree totally with Stu that if you have white prime L lenses, a 2x III Extender is definitely a very worthwhile option to have. and so is the 1.4x III.

I hope this helps. :)

Robin ,briefly ,appreciated,it was exactly your opinion in the field,your experience,I was asking after. I understand the facts on paper ...as best I can,but real world field experience is so helpful. I have only been able to speak to a few folks whom have owned all three bodies Robin. i've asked this question a few times Field experience here with our light is so useful. Plus I know you have more to offer Martin than I

Robin yes I also use the 1.4 ext iii. The 400 DOii takes the extenders very well Robin I'm honestly not sure of the weight difference what it might be between 600 DO and more normal??:rolleyes: optics 600 f 4. I'd have a 600DO in a snap shot if it handled like the 400 DO does... I don't need a 600,but ya know:D

thank you robin It's hard trying to work out what is best for each of us,we are all differnt and shoot slightly differently, this might help Martin... I think these extenders are very useful and if one has enough light the results from the latest tech is amazing. There have long been questions over the 2x and IQ but with the latest tech it's pretty good,

thank you:)

Thanks for the in depth info Robin and its much appreciated too, with this advice in mind from you and Stu in a real world use I have decided that a
2x iii as well as the 1.4x iii will be included in my kit, a friend has a 5d4 for sale which I'm going to pick up tommorow, I'll get some photos put up on here taken with my 400mm DO mk2 using both extenders on the 5d4 in the next few days.

Thanks

Well fellow toggers I have jumped into the world of the full frame photographer, got myself a 5d mkiv off a friend of mine who is going into mirrorless gear, not had a real chance to use it outdoors yet, but I did check out the layout
of the 5div, it seems its similar to the 7d2 in that respect with some extras, hopefully I can do it justice on my days off.

P.S any ideas on a backpack to carry the 5div + 400mm DO 2 and another camera body+ a 70-200mm f/2.8 lens. The bag I have is just made to carry the 400mm DO 2 with a camera body attached plus cards/batteries etc....

....They are similar in handling and controls, menus etc, in fact as all of the EOS camera bodies are. So they are easy to quickly adapt to and use. I have owned and used both the 7D-2 and 5D-4 together.

....I suggest looking at Lowepro. I have the 450AW which holds two bodies plus 500mm prime plus 100-400mm < All Canon EOS system gear.

It's also a size which is acceptable in airline cabin overhead lockers < Just!

Thanks again Robin for the info I got a lowepro Flipside 500AWII which I can get all my kit in and with slightly smaller dimensions than your backpack it should be good for taking on as hand luggage

This was a bit of a bonus as I went to an hide to try out wide angle photography at night using a wifi remote, but Tom who owns the hide/land asked if I'd like to try for the kingfishers that were coming to his newly made pond, of which it was a definite yes. Their were a pair but as is the way I didn't manage to get them together on the same perch. Settings wise it was shot at 1/2500 F/6.3 ISO 800
