I'd appreciate a little bit of advice if possible, I've looked for a thread which I can get some details from before posting however I think due to the age of my 400D there isn't going to be anything recent relevant to what I want to ask.
As the thread title suggests I need to upgrade my Canon 400D. It has been an excellent DLSR which I have owned from new when it was released in 2006 and still performs brilliantly now however as my photography has improved over the years I'm finding that it is now holding me back in certain areas and in certain scenarios where I need for example better ISO performance, a higher megapixel count for prints, a higher fps count, more AF points and just newer technology overall in terms of equipment.
I wouldn't say I have a particular set area of interest in photography, I enjoy a wide variety of different types, it just depends where I go and what is around, it's mostly landscape, astro, animals and wildlife, automotive and portraits.
A friend of mine has recently tried to persuade me to consider the Nikon D750 however I'm trying to keep the expenditure reasonable at the moment and with the Canon lenses I currently own (I know I don't have anything particularly special currently) I think I want to stay with Canon rather than swap everything to another brand.
The cameras I'm considering so far are as follows:
1) Canon 5D Mk3
2) Canon 6D Mk2 (Providing post release reviews are positive)
3) Canon 7D Mk2
4) Canon 6D
I'd like to make the move to full frame for better overall image quality especially when cropped which I do tend to do with pretty much all of my photos, but I'm also considering staying with a APS-C due to the x1.6 advantage I get on my lenses especially on my 70-300mm.
Is there anything I've overlooked with my camera selection in terms of what I am looking to do..? Are there any other Canon camera's which might be better suited to my needs at around the same budget or less than the one's I have listed above (approximately £2000 or less.)
Anything which you can throw at me in anyway would be greatly appreciated, I really do need an upgrade now, something worthwhile with a nice step in all areas and suited mostly to the type of photography I've mentioned above.
