Evening all, I used to post on here quite a lot but I've lost my login credentials so sorry for a first post question. I am needing to replace my Canon 5D which has served me well over the last 5 years into Congo, Egypt and Syria in some rather extreme situations. I recently went to India to photograph tigers and found my focus to be unreliable in the centre point with a canon 300f/4. I again saw issues with my always reliable 135/2 in Nepal when photographing people. The focus seems out by 6 inches to 3ft where before it was spot on. This all coming after the camera was repaired after a fall last year. Anyway, I think it is due an upgrade. I am considering a used 5D2 (around £800), new 6D (around £1k) or a new grey import 5D3 (£1600). I have read through all of the forum posts on similar subjects and it seems that each reaches a slightly different conclusion. I work in the travel industry and regularly need to provide scenic shots of hotels, monuments, landscapes etc which to be fair my 5D can still do fine as a back up. My own interest is street portraiture, either candid or posed. I almost exclusively use the 135/2 to get a really narrow focus on the subject and blur out or distort other regions. I do like to stop the action, I regularly go to protests/riots and try and create portraits within them. I never photograph sports, though I do usually go on Safari in Africa or India once a year, though i wouldn't consider that a must, and I could probably get a used 7D or so if i wanted something for those trips later in the year. Originally I just went online to WEX to get a 5DII, but in reading reviews, the 6D offers far more modern components and doesn't seem to loose out to the 5D2 in any way (correct me if I am wrong). So considering how much i lusted after the 5D2, it seems an easy choice to get the 6D. However, looking at the Grey import price for the 5D3, it is just cheap enough to put a spanner in the works! I appreciate the risks with grey imports, but all of my lenses are either import or used and have never been an issue. I just though it would ask, now if the extra £600 is worth it? I keep fretting that the AF system on the 6D will leave me hanging, but considering what i am used to, and what the 5D2 has offered (and always had me wanting), I also think that it will be just fine for me? I also wanted to understand the cross type AF points. As I usually use f/2, will the 6D let me take advantage of this when focusing? I have never had an issue with my 5D, so I think it should be fine, i have just not really understood what I have read about the AF sensitivity. Does anyone have any experience with the 6D for street portraits? will i rue only being able to really use the centre point? Or will I be so thrilled at the upgrade from the 5D that I will just love it! Thanks for any advice, I would love to save £600 and buy from the UK, but not if everyone agrees that its not a lot of money for much more camera!
