5D2+70-200 vs 7D+24-105

Hi guys!

Here is my big dilemma:

I usually shoot: Motorport (Rally), and Portraits. (aprox 50-50%)

And I was thinking of buying a Canon 7D + 24-105 F4 L + 50mm 1.4
I LOVED my 24-105 on my 40D.
So I know this is a great combination for both, and I was planning to buy a 7D and a 24-105 f/4 L IS plus a 50mm f1.4

Yet one of my friends suggested, I should buy a 5DMkII with a 70-200 f/2.8 L (non-IS), and I started thinking, if I would stretch my budget to the maximum, I could buy the 5D2...
You guys know how it is... And now I have a big dilemma.

With the 5D I would have with the 70-200 as a 45-125mm lens (on a crop).
That is not bad, as I use this focal lenght a lot (portraits, and sport).

The 5D lacks the AF system of the 7D, wich I was really looking for the most.
Yet the 5D is full frame = better IQ, better Bokeh, Larger picture, etc...
How good and reliable is the 5DMkII AF system (Compared to the 40D)?!


I do not usually shoot bursts, so the 8fps does not matter that much to me.
I shoot mainly rally events, where I can get close to the subjects, so I do not need a "super-telephoto" lens.
But I would lack the 24-40mm range (crop), altough I have a 28-70mm lens (hazy:cry, but I would need to change lenses in this case.
And I would lack the 50mm f/1.4, altough in 2-3 months I could get that lens.

So guys, what do you say?! Is FF really worth it, or should I forget it, and get the 7D?

Thanks.
Roland.

I don't understand your 70-200 equals 45-125 on crop. It is the other way, on 7D crop body the FOV is 112-320. On a full frame FOV is 70-200.
I have the 5Dc for landscapes and just picked up the 7D for sports...

As I suspect you'll be shooting at low'ish ISO, you won't see much if any difference really anyway. For motorsports the 7d is the way to go.

I think he means to have a FOV of 70-200 on a crop he needs a lens with the FOV with 45-125

My calculation is:
If I mount a 70-200 lens on a FF body, it would give me the same FOV as a 45-125 lens on a Crop body would give

Thank you guys, for the replies.

I have been using a 40D, with its 9 point AF system, I was OK with it, when shooting motorsport, the 5D2 has the "same" 9 point AF system as the 40D, the question is, is the 5D2 AF system reliable?! (AI-Servo mode)

Is it better or worse, then that of the 40D (50D)?

The second question:
Does FF really make such a big difference in portrait Photography?
How much difference is there?! (Bokeh, sharpness, etc.?)

Thanks in advance.

That is not correct. A crop body increases the FOV by the size of the sensor. For 7D that is 1.6. You multiple that. 70 x 1.6 = 112 and 200 x 1.6 = 320
I think the 1D series maybe 1.3 but may be mistaken on that. The 6D and 5D series are full frame so no additional factoring.

A Crop at 45mm equals 72mm on FF (45*1,6=72)
125mm Crop = 200mm FF (125*1,6=200)

Or am I really mistaken?

Also Dbersh, i see you have both 5D and 7D, if you could only have one, wich one would it be?!

You are mistaken. There is no factor on full frame. 45 on full frame is 45. A 45 on a crop sensor like 7D is 72.
I use my 5D for landscapes and portraits, my 7D I use primarily for sports for the extra reach of the crop and the 8fps. If I had to pick just one that would be tough but I guess the 7D, I could get lenses to accommodate for my landscapes, plus I have the 5D classic, if it was the ii or iii I may have a different answer, maybe someone else can chim in as well who has a newer 5D and 7D with their thoughts.

You're backwards, a Crop at 70 equals about 44 on a full frame, thus the crop. If you were looking into a 70-200 in a full frame view finder at 70mm you see at 70mm exactly. A crop body looking into the viewfinder at 70mm you see just a portion of what you saw in the full frame viewfinder. That gives the effect of 'more zoom' for a lack of better words. That 70 on the crop is actually 112mm full frame equivalent

How about neither? Both of those cameras feature old technology. Have you considered the 6D?

No, it uses a SD card, no way I am going to buy that.
(Not after using my CF cards for years without any problems, and seeing some SDHC cards that broke down.)

Also CF is much faster.

No, you are not mistaken. 70-200 on FF will be the equivalent of 45-125 on crop.

Even if IQ and AF are better?

If I had the money, then I would rather consoder a 5D3, but, the 6D is also more expensive then the 5D2. So since the 5D2 is the maximum for my budget, I did not consider the 6D.

And to be honest there is really nothing "intersting" to me in the 6D.

7D is interesting for the much improved AF system.
The 5D2 for the FF.
