Dear POTN members:
I seek your advice
My case is pretty easy, though it keeps me in a weird mood as I can't make the decision(
As for now, my gear consists of the 5Dmk2, 24-70, 16-35, 135 and 85 - all L-series.
the 5Dmk2 was an upgrade from a 40D, the 7D wasn't available yet, so I didn't see any other options.
I occasionally borrow a 70-200 2.8 IS and a 500mm prime from my father.
I am being troubled by two things: first, I am not quite satisfied with the burst of 5Dmk2 - it feels a bit slow for me(it's 3.9fps vs 6.5 on 40D). That troubles me quite a bit, as most of my photograph is devoted to mu son, and this 2-year old fella is just like me - won't stay in the same place for 5 seconds. So here comes the problem - the amount of photos that I keep is twice less than that from the period when I used the 40D. When looking through the archives, I clearly see that the speed was an important factor - When I bought the 5Dmk2 I didn't think it will pose a problem, but it turns out I was wrong.
Second, is that, when using the cropped 40D I never needed a telephoto zoom lens - 24-70 and the 85 prime were sufficient enough. Now, as the new 70-200 came out, I think it might be a good investment to get one of those, as I have a lot of experience with the 1st version and it's an amazing lens, in my understanding.
The bottom line, as I see it: two paths:
a) Downgrade the 5Dmk2 to a 7D, as it's twice as fast, and get a new 70-200. That's within my abilities and is easily doable.
b) Stay with the same lens, but upgrade the 5Dmk2 to a 1Dmk4.
It's pretty much the same when it comes to calculating the cost for the 1st and 2nd choices. I'm struggling which path to take, as, on the one hand, I know that 70-200 is a great lens, but, on the other hand, the mk4 is a great body. The budget for photography is set for this year, so there won't be any significant additions until the next February or so..
There is, of course, another way, like to get a slightly used 1Dmk3 and the 1st version of 70-200 2.8 IS,or wait a while and get the 2nd, but somehow I don't feel like going this path.
And, of course, there is another one: keep the body and get the lens, but I don't think I'm going to achieve my goals this way.
I would greatly appreciate all advice and suggestions..
