why would EX1 be better than RED Epic ?

Vitaliy
I'd like to ask this thread gets deleted and forget I ever asked.

Vitaliy
I missed for some reason the last part of your post.

QUOTE
About your 50mm test.
You are comparing different things.
Full frame image projected on ground glass and shot on good small sensor camera.
And center crop.
-------------------------------
I think there must be some misunderstanding here as the EX1 with the letus and the Pentax 50mm lens shows a much better resolved picture than the GH2 with JUST the pentax 50mm lens. AND the SAME pentax lens is being used with the EX1 and with the GH2.

MY TEST
The two frame grabs I supplied are both shot with an EX1.
1)One frame grab shows the EX1 alone so the comparison is to the EX1 lens
2)The other frame grab shows the EX1 with a Letus adapter with the pentax 50mm lens. This means the EX1 with letus has a lot of glass in front of it and an expected drop in resolution because of it..

Neither frame grab shows the GH2.

The tests I've done with the GH2 show the SAME 50mm lens on the GH2 using an adapter. I did wonder if the adapter may be out a bit but then looking at a monitor the resolution is much higher than being recorded.

I think I'm going to have to assume the GH2 resolves about 650 lines until I can get tests done myself.

Vitaliy Yes I think your right! Problem is those charts are so expensive although undoubtably an investment. Maybe I will.

Thanks Vitaliy I'll keep watching to see if the hacks change things.

RRRRR

The testing I have done is with a single lens A Pentax F1.4 50mm used with the Letus on an EX1 and used with the GH2 Now the lighting was different and the GH2 was used indoors with a single dedo. I have already said this. Okay its clear there are no line resolution tests for this camera so unless someone has these I wont respond to any more posts as its clear everything is based on experience hear say and emotional feeling.

RRRR What 16mm frame grab? One was an EX1 only and another was an EX1 with a Letus.

Derek No I am not a troll I recently bought a GH2 A zacuto monitor to go with it My intention was to use it to make a film All I want to know is the cameras resolution which after doing tests have discovered compared to an EX Or an EX1 with a letus adpater the GH2 image is softer and therefore would like to try and find out what the line resolution is for a GH2

You know every pro camera out there have these tests actually asking if there are any seems to some to be some sort of criminal offence punishable by name calling and derision. My goodness is it so scary to know what the damn camera resolves.

@brianluce seconded.

I've used gh1 footage on large projections and although I had issues with some of the noise (macro-blocking in certain areas of the spectrum), resolution was definately not an issue. I saw details which I didn't see while editing when watching the projection up close.

Note: it was a full HD projector, 10 metre wide projection. (DIY setup - the projection could have been much better with more time and care) Also, the lens setup used for that particular work didn't work in favor of resolution, which means that the image was a lot softer than what can be achieved.

The GH2 has a lot cleaner image, better resolution, and better noise rendition - especially in gop1 footage. I'm very confident it would look gorgeous on the big screen.

If you really are concerned with resolution, try out the GH2 with optics that is known to work well with it and full frame cine lenses that you can get hold of.. There are notable differences between different lenses on different systems. Even between the GH1 and the GH2 some lenses do not work as well on the gh1 s on the gh2 and vice versa (although this is of course subjective to a large extent) so I suggest you do not assume that one single lens will give you the cream of the gh2 because it has produced good results on other systems, or is reknowned as a good lens, full stop.

When looking at the screen grabs above, I find the 16mm footage looking better - because of the fringing on the ex1 (producing dv-like results), even though the grabs seem to contain more detail. But that is just me. Add sharpness in post to gh2 footage if you want a similar look.

I suggest getting a bunch of lenses that you can try out on both setups - then you will have a much better idea of which camera produces the results that you want. No resolution test alone will give you that info, and it's especially wortwhile if you are planning a £100k project. Maybe even renting a camera would be wortwhile for your project? If you don't try it out then you will never know, but IMO it would then be quite rash to use the gh2 just because it is cheap or the ex1 because you have used it before.

I'm not saying that you should splash all the cash on trials, but surely it would be more wortwhile to do screen-tests with different setups and different lenses than check at resolution tests alone.

That's what I would do.

There have been some other tips but check also out the real-world Arri, f3 and gh2 comparison topic if you need more arguments (as to why the gh2 might be worth an effort)..

Oh, and by the way - if you are planning on shooting a lot outdoors, then the gh2 is propably the best cam I've used for shooting landscapes / nature scenery on video.

There have been tests, check for the GH2 versus AF100 posts -- there was a stir when it outresolved the AF100 -- Berry Green almost had a breakdown. Generally there are complaints about the GH2 -- for example under some circumstances you can still get aliasing, banding pops up under some circumstances, 8 bit limitations, lack of great wide angle solutions, weak audio and others. But generally, resolution has been one of the strengths. I mean, look at this forum, engineers and shooters are obsessive compulsive about squeezing every little last drop of image quality from the GH2 and yet you won't find much concern for resolution -- presumable because everyone is pleased with it -- contrast that to a Canon forum where resolution *is* an issue.

Brian the problem is without proper testing no one knows! Have you got links to those reports?

danyyel its not much use looking at web compressed videos really. Thats why I've posted some frame grabs.

On a lot of sites you have people paid by manufacturers to skew results IE Often highly respected Gurus in the pay of a manufacturer or selling lots of gear while sneering at anyone who dares say anything that doesn't make their brand the greatest in the universe and a lot of rubbish is talked about cameras and what they can do. There is a reason that an Alexa can command such big money and why film shoots have expensive gear and its not because they are pixel peepers or measurebaters These put downs are often used by those with a mission that either makes them money or because they support a product like a football team. I've seen so called nuetral forums do this. I am none of those and I dont see any reason why GH2 owners should be afraid of the truth. If the truth can help make better films lets get it out there. I'm not here to rubbish any camera I want to know what the tools can or can't do.

After doing more tests this morning in case I got it wrong I can say the GH2 is definately softer compared to an EX1 or an EX1 with a letus adapter. I'm wondering if this is the same resolution as a panasonic af101 Although the GH2 has a bigger usable sensor so maybe its slightly better. That would then be maybe 630 lines which is below even 720p and perhaps unsuited to big screen projection. Has anyone seen GH2 footage projected? I am fumbling in the dark with this as no one has done proper testing and overlooked what is obviously the best DSLR and probable mid range camera out there. Maybe to many vested interests are at stake.

Those frame grabs I posted using an EX1 have the sharpening turned off. There is no sharpening although there is colour correction.

@mark2929 there is still a way to go with HDMI capture out of this cam... lets hope that the new firmware that has just been released by Panasonic has some hidden gems that allow VK to understand more about this topic!

@mpgxsvcd

I listed sharp primes :-)
One ones that are sharp wide open :-)
