About 7D And GH1...

[Polanski]

I would like to buy any of this camera.
Is there any article comparing the pros and cons of each?

Thanks

Just a quick list...I'll edit it with other comments.

7D

Pros:
- Native 24p, no pulldown
- Relatively better codec
- Low light sensitivity
- Possibility for shallower DOF
Cons:
- Aliasing/moire
- Fixed LCD
- 4GB filesize limit (roughly 12 minutes)

GH1

Pros:
- Can accept pretty much any lens with proper adapter
- Record time limited only by the size of recording medium
- Flip-out rotational LCD
Cons:
- Compression/codec can create mud
- 24p requires pulldown in post

Some people like the look of the GH1 image, some prefer the Canon. My advice on everything in general - go to a camera store and try them both out. Bring an SD card and a CF card, take some footage, look at it at home or in the office, throw it around for quick CC and get a feel for things. Sure, you'll just be shooting in a store, but that should be enough to give a general feel.

Does anyone know if the resolution of the GH1 has been measured on some charts anywhere? That would be an interesting comparison.

I know this isn't what you asked for, but this article by Philip Bloom compages the 7D to the 5D:

The one comparison that I would like to see between the 7D and GH1 would be a rolling-shutter comparison. There have been none yet. You may have to wait for the 7D to become more widespread before you see a direct test between the two.

im sure its no question that the GH1 is much better in terms of rolling shutter over the 7D, we've seen some good examples and i think the GH1 comes pretty close to the RED in those terms.

The problem is that it's only really good in 60p mode, so the comparison isn't very fair.

really? hmm, thought i had seen previous tests with it in 24.. I could be mistaken.

One of the first things that I did when I got my GH1 was test the rolling shutter in every mode. I did the standard whip-pan test. In 60p mode, it was essentially imperceptible. In 24p and 30p, it looked pretty bad. So there.

I just did a test in my apartment for the rolling shutter on the GH1 in 24p mode.

This was shot with the kit lens at 14mm, with Mega O.I.S. on Mode 1.

Don't forget crop factors.

Compared to full frame stills:

7D = 1.6x crop
GH1 = 2x crop

Getting fast wide lenses on the GH1 is even more challenging than on the 7D.

Was all that nastiness in the beginning on the footage, or is that youtube?
