GH1 and T2i which is the one, no flame here

My Canon 7D and Tokina 11-16 f2.8 would beg to differ. I've never had any sharpness issues at full wide with any of my Canon lenses.

But if we're discussing other variables as DOF, smoothness, glass choice and such, ISO, etc, we need to be able to tell a different story then.

This is a good assessment, Emanuel. We saw this when Richard Darge did some of the first light comparisons of the 5D to RED. Since 5D/7D/T2i are horrible as far as aliasing/moire goes, the detail goes to hell on wide shots with lots of information as far as video goes and looks crunchy/bad. Versus the RED which can resolve down to finer detail.

The GH1 exhibiting less moire aliasing etc is going to look "cleaner" and more "resolute" on the wide end, with the compression hack much more than the Canon crops.

However, that's just one part of it all. This is exactly why I want to try out the PL mount on the GH13 in addition to high speed PL lenses. This should happen within a day or so.

It will be interesting to see how the whole story works out, and I am hoping it's a good one so that I can keep the GH1 for small jobs in which I do not want to lug the RED around.

If not, then I'll continue to just shoot RED MX for everything and maybe borrow a 7D and use what glass I still have.
 
Not about lenses, I don't think, just the way the cameras make a 1080p or 720p image from the full sensor readout. Compare a video & still of the same wide shot with the same lens, shutter, f/stop, ISO, etc., and you will see the difference. Or take that still into Photoshop and downres it to 1920x1080, then compare that with the .MOV - no comparison as far as resolution and detail goes, and lack of aliasing.

What some are finding is the GH1 with new firmware seems to do a better job of outputting a crisp 1080 with some of the issues the Canons have, presumably because it's using a better downscale method.

We must remind ourselves that Resolution or Resolving Power is not the only characteristic of a lens.

RED Pro Primes resolve a tremendous amount of detail, they are still no comparison to Master Primes for look.
 
Yeah yah! I saw it. Not my personal way of shooting and not my personal choice in glass. RPP's are a bit eh to me. Got a Mattebox, rods and a full set of NDs ready to test with the ZMPs though!

i agree with you about the RPP.. pretty character-less and too perfect for me.. (but we were on lunch and the box of lenses was just sitting there.. who could resist!)
 
I'm probably buying a camera in the next few days, and it can either be a t2i/550D or a GF1

GF1 pros:
* less troublesome line skipping, aliasing, and moire (formerly I stated "no line skiping", then got corrected)
* really small: with 20mm pancake I will take it out much more often
* may eventually get 4:2:2 at 1080p under AVCHD (and I think it's already working under MJPEG)

GF1 cons:
* FPN/banding
* no manual controls for video so far
* no way I'm going to be able to pull focus on such a low-res screen
* worse under low-light
* shane hurlbut says GH1's footage looks like video, not like film

so the t2i is winning so far

The GH1 definitely line-skips, has aliasing, and has moire. All DSLRs do. The difference is that on the Canons there's also chroma aliasing and color contamination to the moire (purple/orange), whereas on the others (Panasonic, Nikon, Pentax) there isn't.

But don't think that you're getting away from aliasing -- they all do it.

Why would you be putting up a GF1 against a t2i anyway? The proper camera to compare there is the GH1.

Where did you hear this? I searched Hurlbut's blog and nothing like that popped up.

If you need outside testimonials, Robert McLachlan, ASC seems to like the GH1 plenty. And that was before the GH13.

Here's an extract of a post McLachlan made on Illya Friedman's Hot Rod Cameras page, about the GH1:
At Technicolor Vancouver I viewed the material with master colorist Gary Shaw and we both cracked up when we saw it. It’s SO good. Gary had timed 16mm and 35mm stuff I shot 20+ years ago and was amazed. The camera was sitting on the bench beside us. Phil meanwhile looked hard at the colorimetry and declared it really good. So…. on Sunday I mounted it in an unmanned ambulance going 40 mph. that we crashed into a concrete barrier and the footage is terrific. It will appear in the new FOX series Human Target in January following American Idol… so stay tuned. I can’t wait to get one of my nice Cooke S4i’s on it.

major reasons to consider a gh1 over a canon would be if you need autofocus during video recording,or the live viewfinder, or the live histogram, or the articulating lcd, or you want to get rid of the purple/green moire that the canons exhibit, or if you want to shoot 4:2:2 intraframe instead of only 4:2:0 long-gop, or if you want clean/sharp 720/60p.

lol

I love my GH1 and have not even upgraded the firmware yet. I probably will at some point once the dust settles.
 
Do it, wait until you see these!

Do it, wait until you see these!

Stay with 50/60i, go with 60, 62, 70, they are mouthwatering.
 
Seriously, you need to check out these new settings, as it stands this could be more than enough for anyone;-)
 
How are you guys getting good focused images if you can't monitor it externally? Also isn't the GH-1 screen lower resolution compared to the T2i screen?

I understand the histogram view is on the GH-1 but is it still hard to get great focused images just with that?
 
Well it's got a really good autofocus mode in video, usually I just turn that on, let it auto focus, then I turn Manual on and tweak from there. Usually letting it autofocus is good enough, it's nice and sharp I hardly ever have to tweak it.

It's also got a focus assist mode so it magnifies the image in really close so you can clearly see how focused it is or not.

The electronic viewfinder that's active in video mode is more hi-res (1,440,000 dots) and it's great for on-the-fly focusing. No need for a expensive strap-on loupe. Check "The Farmer's Flea Market" in my sig link which I shot entirely by using the EVF.

For more repeatable shots I use the focus assist magnification quite a lot, it's fast and accurate, so it's very easy to set markers on my follow focus.

This histogram is for monitoring exposure on the fly, not focus.

I asked in the comments of the post about "Turning Still Cameras Into PL Mount Movie Makers ", and he answered; I consider him the most critical and difficult-to-please of all the DSLR revolution bloggers

for me the natural comparison is GF1 vs T2i, because those are the ones with the same price; GH1 is much more expensive... unless I get a japanese body-only deal on ebay, which I consider quite a risky thing to do (lots of things that can go wrong)

(I'll modify my post about line skipping)
