need help

[chasn]

My present gear is 7D, 5D2, 70-300L, 24-105L, Zeiss 18 and Zeiss 50 plus Kenko 1.4 TC.  I have about £1000 in my camera fund which is sort of earmarked to upgrade the 5D2 to a 5D3.  ( Subject of course to the 45 mp camera not becoming available in two weeks time at £2000 and waiting to see what else might just be around the corner).

But wonders of wonders I have a little old pension policy about to mature which will generate a little extra for the camera fund without my wife getting too excited about it ( say £2000) and early in the new year I might trade down my car which might also add £2000 to the fund.

So happy days! 

I am a pure hobbyist, mainly taking pics of my kid doing sports and general family and travel pics.  So the 7D and the 70-300 are non negotiable as is the Zeiss  18 but after that how best to spend my ill gotten gains?  It needs to be something special.

Thinking the 1 Dx is just too big and showy for what it adds compared with the 5D3 plus lenses?
Thinking people like the new 24-70 but given its price does it really add much for me compared to the 24-105 given how much I love the Zeiss at the wide angle?

Thinking I don't like the 100-400 at all and sold a copy a while ago.
So does it come down to a choice between the 135 and 400 5.6  or the 70-200 II IS. + 2 X TC III ?   Or if both boats come in do I go for a real super tele?

What would everyone suggest?  ( PS I am a Yorkshireman so don't need to spend all  the camera fund even if it is there.....)    Of course there those telling me I should ditch the Canon FF stuff and buy the D800 but I am not convinced.....

I bought a 5D MK III to replace my 5D MK II and thought $3500 was too much for the differenc3, considering the features I use, so I returned it and bought another 5D MK II from the Canon refurb store for $1400.
Then, Adorama popped up with a 5D MK III for $2750 and that was the right price so I bought a second one.  I also sold the 5D MK II for a $300 profit, and got a $56 ebay bucks credit.
I gather you are in the UK and can't easily buy from the USA, but I'd look for a deal on the 5D MK III.
You might also consider a 100mm L, mine really loves my 7D.
(I also tried a D800.  Nice camera, but I found it impossible to buy equivalents to some of my favorite Canon lenses and resold it).

Do upgrade your 5d II to III - I'm really happy with mine. 1Dx will be an overkill and you can use the £s towards more glass.

I'd suggest 135 since you mainly shoot family and travel etc where as i'm not sure how often you'll use the 400 5.6.

Happy shooting.
