So, after lots of thought regarding a second body/backup body (my 7d, I just don't trust it anymore after using the mk3 for a few months), I'm kind of feeling like I have 4 options:
buy a second mk3 (would have to wait a bit to do that)
buy a used 1dmk4 (seeing used prices of $4000-4400, so, like mk3 would have to wait a bit)
see what this entry FF is like/can do
see what the 7d2 may bring to the table
All of these options require waiting (I have considered a 5dmk2, but I kind of want something that can hold it's own up to ISO 6400 and not look like a joke compared to what the mk3 can do. Maybe if used prices go down...).
with the way the market is though, these new canon models probably won't be available for a while (possibly the entry FF, only because they may want that on the market for Christmas season, but I don't see the 7d2 being available till sometime in 2013)...
So yeah, this has me pondering things like...a 1dmk4? The only experience I have with 1 series bodies isn't even shooting with one. I recently shot a wedding and had a second shooter with me, he was using a 7d and a 1ds3 ---and wow, as I was going through his files, I could immediately know which came from the 7d and which came from the 1ds3---at ISO 1000 the 1ds3 file was a joy to work with, colors brighter and sharper, almost better than the mk3. I'd kind of love to rent one cause I am sure that would be fun to shoot art and portraits with, but the 1ds3 definitely isn't a low light monster, so while it would be fun, its not what I need. It is an eye opener though, and knowing that the 1dmk4 used is basically the cost of an mk3 with grip...yeah, that has me thinking...
So I am wondering from all ya'll that have used both camera's, how does the 1dmk4 hold up against the 5d3? How is the 1dmk4 at higher ISO's? It's a 1.3 crop, so that is kind of interesting and unique. My guess it would be a true 2nd body as opposed to merely a backup body (IE, I'm going to try running with both camera's this saturday, but, in a pinch, will I opt to switch lenses and not risk using the 7d or will I go for the 7d? I would have less hesitation if I had an mk2 as backup. And I'm guessing that with a 1dmk4 there'd be zero hesitation, and I'd go to that without fail (I have read that it's just an amazing camera!)
So from you, the people who use it, how is the 1dmk4?
And from those who own both, how do they compare?
