Sigma DP1 vs Canon 1Dmk3

I know this sounds a little ludicrous, but, I have this both and have been considering testing them out against each other because I think 10mp is a fair comparison to the DP1 and also I am so thoroughly impressed by the image quality of the DP1.

Anyways, I saw that someone on Pbase beat me to it. The following is not my Pbase site and I hope the gentleman whose it is does not mind, but, I'm positng the link anyways. http://www.pbase.com/hughden/dp1comp

I may be able to do something more rigorous than this this weekend, but, I'm fairly busy.

Re: Sigma DP1 vs Canon 1Dmk3

now that is mean, overexposing the poor Canon...

Looking forward to another comparison. Would be cool if you could make a little raw pack available!

Dp1 seems to have a better dynamic range. (or is it lower contrast, underexposure and changing light?) In the pic. n. 3 it almost looks like there was a polarizer on sigma.

Unfair ...

The 24-105L is no match for the DP1´s lens.

Re: Unfair ...

Personally I think when used on a full frame camera, the L lens wipes the floor with the DP1 lens at every focal length except 28mm...

Re: Sigma DP1 vs Canon 1Dmk3

Wow. The DP1 can compete with the best of them in the IQ category. I still cannot believe when i see it beating the output from a DSLR on a regular basis. This is turning out to be one heck of a camera. I could not be happier with my purchase of the DP1.

test-procedure

do not even think about using a canon-zoomlens.
go up to a high-building and set the lenses to infinity.

then rotate the cameras in the way one could see the same parts in all important zones. center, center-up, center-down , center-left, center-right, corners

if comparing against film. think about that film is not flat when coming out of the cartridge. would be better using contax rts IIIcontax 645 vaccum or pentax 67 with vaccum, hasselblad 70mm, pentax 645 70mm(amazing lenses). use only the best scanners.

Re: test-procedure

Thats one way to do it.

My way would be: Use each camera like you would usually do. If you usually shoot with a zoom, use a zoom. If you usually shoot with vacuum scanners do it. Cameras are usually used under less than ideal conditions so both tests are equally (non-)telling and equally entertaining!

Re: i have the same problems....

In defense of Dmiller, I think he was being sarcastic....In defense of the Canon lens, it is a zoom.

Re: i have the same problems....

...and in defense of me, I don't have a prime Canon lens of an appropriate size, so I had to use a zoom!

As I say on my Pbase site, it is not a very scientific test, but the fact that the DP1 can hold it's own against the 1D, albeit with a zoom lens, says I lot to me about this amazing little camera.

I am looking forward to someone testing the DP1 against a 1D with a prime; I bet it will still do well.

Wow, in that case, I am delighted.
I don´t remember Dmillier joking before.

More of that please!

Most certainly.
Thanks for the comparison anyway.

You are quiet right as usual...it also wipes the floor with DP1's or most of my Sigma lenses with fantastic CA too...even at f11...that is most surprising to me, since it is coming from such legendary L line and all.

It is a thankless task...I had always though that this model of 1D is more for sport/wild life shooting with gazillions frames per second, which will leaves DP1 in the dust in that departments...The prime with equiv. FOV would be nice...thank you for the test.

Re: i have the same problems....

Hugh, no need to defend yourself, I'm happy you beat me to it. I hope you don't mind my linking to your pbase sight, if so please accept my apologies.

It's really unfair to be looking at this comparison from a lens standpoint...the 24-105 is a 4.4x zoom, its being compared at one of its extreme focal lengths where its reportedly at its worst. The sigma is an F4 lens designed specifically for this camera and its sensor. When looking at this comparison its probably best to analyze the contrast ,color and such qualities....not the extreme corners on a zoom lens.

I have the 24L mounted on my 1d3, and if time permits, I will hopefully do a quick comparison between the two cameras this afternoon. They will be hand-held (sorry, I don't have the time or desire to break out the tripod) and they will be shot with similar settings and then with the canon stopped down to equal the dof of the DP1. I may also do some over/under exposure shots and see how well each can be manipulated...of course, this will all take time I may not have, but I'll do my best

Re: i have the same problems....

No problem with your linking to my page Evan. I did the comparison for my own interest and to convince my wife I had made a good choice!

The 1D is a stunning camera, especially for sports photography which is what I mainly use it for; but the DP1 is going to be a great companion to carry everywhere.

Looking forward to the results of your more comparative test when you have the time.
Cheers
Hugh

Re: Sigma DP1 vs Canon 1Dmk3

If you look at the third comparison the red floweres in the hedge have all been lost in the canon.
That is a bayer issue of the highest order.
