1D Mk III vs 7D please i need advice !!

[dimidragos]

Im already 5D Mk II owner but i want second camera body. I have opportunity to buy one 1D III use by amateur, in god condition, with only 20 000 exposure with around 1600 eu (2400 usd). I just ask if you think that 7D is a better choice if we think also that in Europe where i live is same money or maybe more expensive. Thanks for your advice!!

It depends what you want it for. The 7D will give you a shade more reach on long lenses and a little less wide on wide lenses. The 7D will give you more ability to crop or print very large because of it's higher pixel count and will fire flashes remotely. The 1DIII is more weatherproof with a longer expected life. The 1D has built in vertical grip. The 1D has slightly faster frames per second.

Personally, owning a 1D Mk III and having played with a 7D for a while, I would choose the 1D every time but that's purely because it suits what I shoot and the way I shoot it.

They are both stunning cameras with slightly different abilities, choose the one that best fits what you'll do with it.

The 1D3 is a significantly better camera, so the decision comes to what you need the second body for and how important the difference in price is to you.

I think a 1D3 and 5D make an excellent pair, each with different strengths.

i Have a 1dmk3 and have the 7d on order i want it for birds mostly on the ground ,it will give far more than a shade of reach in fact it will almost double focal lenth for reach .
1DMK3 500f4isL 1.3crop = Field of view 650mm 10mp on subject
7D 500f4isL 1.6crop = field of view 800mm 18mp on subject so if you now crop the 18mp down to 10mp your field of view would be more like 1500mm aprox .

i keep getting you and that other guy GbRandy mixed up. i was expecting a 1dm3 trashing post heh heh.. no offense to GbRandy who has had some bad luck

anyway

Glad to see someone from my neck of the woods.

I wouldn't include pixel count in a focal length calculation as you then run into problems with resolving ability of the lens as well as depth of field change and noise from cropping the image. In ideal situations you may be able to crop an 18MP image down to 10MP and have an image that's close to the IQ of the 10MP equivalent but mostly, you won't.

I own both 1D mark III and 5d mark II. I used to own 40d and 50d and recently tested 7d. I thought one day dat combination of 50d and 5d mark II could replace my 1D mark III. Boy was i wrong.

At that price you definitely should opt for the 1D mark III. Quality of the individual pixels and high iso performance is just phenomenal. Although on paper resolution power of 7d should be better compared to 1D mark III, in reality it wasn't the case.

yes but i will with my lenses

IQ wise, the difference isn't that dramatic. The MKIII is a touch better in hightower ISO.10fps vs 8fps isn't a big difference.

However the MKIII has much better build, bigger buffer, and the faster AF system.

If you need to shoot at ISO 1600 in raw and expecting noise free image, go 1dmarkIII.....


Well, once again, my Kinglet shots recently at ISO 1600, on a 1markIII and 500L.

Enjoy... Now, let's see some 7D bird shots.... Maybe at iso 1600? In Raw

Only if you have magic lenses. You'll certainly lose a pleasing looking narrow DOF with lots of cropping at very long focal lengths. Not so bad if you just take record shots but without lots of PP, you won't get anything that's artistically attractive.

[nicksan]

...and once again, The MKIII does not produce noise free images at ISO1600. As for bird shots, why don't you look around? There are plenty, and a lot of BIF ones too, not just perched ones.

Really, I am not sure if you are conveniently overlooking these...

Well i know what your saying of cause but its not my plan to have to crop to much when i get the 7d .
But i do think that overall haveing more MPs and the 1.6 crop will give that bit more pulling power over the same lens on the mk3.
i use 500f4isL 300f 2.8isL 70/200 f2.8isL 24/105isL 85f1.8 and 50f 1.4 so i dont think i need worrie to much, it might strech my sigma 150/500 hsm os a little though.

Thanks to every body. My main reason for this second body is of course the crop factor to multiplay the lens focal. In same time i want to keep same image quality and low noise at high ISO. I`m not so satisfait about build quality and weather seal in 5D and i want one upgrade in this direction. I think my option will be 1DMk III....but i still wait other conclusion ...
