Thank you Stuart for the kind comments.
I've used an extender on the MkII. The Red Kites above were taken with a 500 f4 + 1.4.
I think that both the MkIV and MkII are fairly close in terms of ISO handling. I feel that the noise on the MKII is a bit coarse but there are some very good noise programmes to use to help with it.
New cameras are a learning experience for most people. Moving from a 1D MkIV to a 1DX at first glance doesn't seem a big deal. In reality the extra features on the 1DX need some time to learn about and to get the best out of them. So it will be for you whatever you decide to buy.
Most of my time now goes into trying to set my cameras up so that I don't miss opportunities that present themselves and having confidence in the camera is an important part of this process. Learning about the different AF cases etc and when to use them. I have that confidence in my 1DX but not quite as much in my MkII. As Bob posted above, this isnt about single point static images, its about movement and BIF etc.
Personally I would go for the MkII, but its a close decision. I do think that the AF system has a definite edge on the MKIV, but I found the MkIV very quick to lock on when I compared my 5D3 with it but the 5D3 tracked better.
As an example of relatively high ISO images this is one at ISO 2000 when I was messing around with my 1DX just after I bought it

And for something more extreme this is ISO 6400

Hiya Gaz,sod it, I wrote a load of stuff to you last night,I'm in a constant rush I couldn't have hit submit when i ran off lord I'm hopeless humble apologies sorry mate!! Buddy I remember starting with how grateful I am for the pictures and the time taken. I'll be reading back through this all a few times no doubt,trying to absorb all the details and opinions so kindly given. The pictures as well as illustrating your points are also a thing of beauty to stare at ..... your making my study into a pleasure !!
Gaz lets start with the extenders,do you ever use the 2x mark iii version. I'm side tracking a bit ,but in many ways how the cameras might preform with one is part of my evaluation. Gaz I'm under the impression that both mark iii versions ie 2x and 1.4 times were designed to preform at their optimum with the mark ii superteles. Again i'm under the impression that the image quality took a step up with the 2x mark iii whereas maybe the 1.4 didn't change so much, but sure other benefits were introduced stronger at the mount point the chip to work with the newest lenses etc.. I'm also under the impression that the extenders slow focus, this seems relative to the amount of "magnification" ,logical, if I've understood my reading correctly. So Gaz first up have you any thoughts on IQ relative to a 300 f/2.8 is. Second would you have a preference for one body over another to drive these lens extender combination. I don't shoot with an extender glued,tis all about shooting senarios,but it seems pertinent that I ponder the cameras' performance and dig for thoughts there of relative to the gear I have now , Gaz how do you feel about the 2x iii image quality?
So if one took extenders into account would that make any difference in one's choice,or maybe i'm just way of the mark and this shouldn't be part of my reasoning process ,in trying to decide on the right choice for me?
From my previous exploration I had come to the conclusion that the iso performance of the iv might be slightly better than the ii ,it is in my uneducated world part of the iv's plus points,but you feel they are very similar thanks for this.
Gaz your notes on lock time,tracking and the iv and the 5Diii:,I found a comparison betwixt the "7Dii the 5Dii and the 1Dx at the" digital picture"(interesting read I'll provide a link if anyone wants it),these cameras all use a version (not saying it's equal) of canons AFiii AIservo autufocus technologies (I think I have that correct), chuck Westafall (sp?) mentions the 5Diii to be the slowest of the 3 on initial aquisition. Could you draw out that to the iv and ii does the same thing equate if one replaced the 5D iii with the 7Dii. ,or alternatively why ,what areas do you think the 7dii has the edge focus system wise. Ha and yes this is utterly about movement !!!!
Finally,this is completely off topic but it is so important to me and was not part of my post last night
, Gaz Stoo please don't fall out because of me,if you have differing views it's cool,but my post has sparked a disagreement,that I wish wasn't happening ,guys life is too short to worry on such things .
Lads for 9 years I've been a care worker,i've done all I could to help a mate fought the fight,oh and by god some more,last year 6 day weeks, 12 days off no chrimbo . Up until 6 weeks back!! Finally(after so much hardship) I thought I was winning my mate had a Dr listening to the dumb carer(me) my mate went from dropping of the planet to a guy adoring life best health for years. I went to work not so long ago and found he had passed,I found him .
With my camera(he couldn't see like you and me) and my love of nature I and my lass opened a door into a wonderful and amazing world he had never seen ,ahh few do. I have felt for a long time that this forum is wonderful and amazing,but there is a problem,folks defend here instead of being cool with a load of mates that love the same thing.. I'm utterly bewildered by the kindness you guys have shown to me,you don't know me,you have no reason to help me,but you are trying with everything you have. The one thing I wouldn't want is to put more sadness in the world,life is utterly too short and basically I'm trying to put a perspective on that by telling you about something horrible that I own...Please there is no need for any thing sad on any thread of mine,differ on opinions cool,we are all not made the same.,if we were the world would be just what? Please have fun with me,you both take these wonderful pictures that show your personal love ,lets keep that big picture perspective on what is important. As much as this thread is about which camera is important,oh and this is monster for me,I just don't want any animosity or sadness created because I posted here.Please show your passion and love please educate me please give me a perspective on how you do it,
But let's do it with big smiley thangs huh,life really is too short and too precious to waste especially when we all have that same passion,
take care
Stu
