GH-1 vs. t2i - bring it!!

Yeah, at 2:06 I may have been at ISO 1600. It was really dark out there.

I'll let you know when I get to that candle test.

I think the banding problem shouldn't be completely blamed on "low light" though. It's been proven to be an under-exposure problem for a given ISO settings, 2.5-3 stops under I think.. It also seems *very* related to contrast too, and that's why you don't see a lot of banding in these "low light" shots in this thread, because there is a TON of contrast. Shooting a candle, IMO, would be high enough contrast that you wouldn't see the banding. Shoot a diffusely lit blank wall and you'll see it all over the place.

I can even get banding in very highly lit situations too if I do something stupid like stop-down too much to try to avoid clipping in bright areas. It's just easier to get banding in lower light because your contrast starts going down too much.

So yeah there are folks who just say "light it properly" and all that, but sometimes you just can't. sometimes you do it for effect, sometimes you do it at the spur of the moment, sometimes you want to give it a try even though you know it's wrong.

Thanks for sharing but, this is not my idea of low-light- there are many many sources of light here .

very familiar w/ this vid Martti as it was one of the very influencial vids to see just before plunging into the GH1 vortex.

You're an exception you crazy bastard:beer:

but seriously, didn't you do some noise reduction in AE? so do you recall any banding or anything like that?

what the hell's wrong w/ my cam?????

YEP! so are people using different scene settings for low-light? i.e. SMOOTH w/ more contrast, noise red. etc NATURAL, NOSTALGIC, yadda yadda

I always do noise reduction in post on digital footage and then add some film grain to get rid of the deadness of digital. I've noticed using the Remove Grain filter in After Effects with a fairly gentle setting take away most of the faint banding I see as soon as there's movement and a moving camera. I've also noticed that some people have the fixed pattern streaking a heck of a lot more visible than I so guess I got lucky with the sensor in my particular GH1. (BTW please stop referring to the FPN streaks as 'banding' - that's a whole different problem concerning the limited 4:2:0 colour space of all HDSLRs)

When claiming 5DmkII the ultimate low-light camera most people tend to overlook that to have a workable DOF for follow focusing when doing none rehearsed takes aperture needs to be at f/5.6 or even a 5.6-8 split - the latter gives the same DOF as GH1 has at 2.8 and OK, 5D is better but it's not two and a half step better. Versus 7D/550D the DOF difference to GH1 is almost a step so again it's not such a clear-cut deal as often said. Especially as soon as one moves into real work and not just opening up wide and shooting random stuff with little movement.

I found that one of the settings gives you slightly better brightness in low light. I can't remember what it is offhand though, I'll have to take a look when I get home.

I posted a link to this thread in the Canon EOS 7d forum- but people are responding there as well.


Ben, (or anyone) can you comment on this:

originally posted by N.E.S.:
"I owned a GH1, now own a T2i. Yes the T2i is better in low light. One thing I must note though is the GH1 has banding in low light and the T2i has none, which to me was an easy deciding factor on which to keep.


Overall though IMO the T2i is a better camera for video and at least x2 as an actual photo camera. The T2i uses newer technology and simply compresses less allowing for more information and better video quality when used correctly.


If you are looking for that amazing low light camera though it would be neither the T2i or Gh1 but the Canon 5D."

GH1. Street at night is available light. After I color corrected it got maybe a half a stop darker. Inside bathroom is practical light...probably a 60 watt incandescent, same with inside the guy's bedroom. The girl's bedroom was done with almost all the lights turned off, and a barndoors nearly closed 150 watt light bouncing off a wall. The party was done with the same light, and a 500 watt work lamp (which is diffuse enough to not be hugely bright.) The night street was mostly done with a nikkor 50mm f/1.4, wide open or at f/2. ISO 800. The film looked pretty darn good projected on this screen:

(thanks to whoever's flickr that is) on a projector that could fill "half" the screen (it was the middle "half.")

I haven't heard of the successor yet? NAB maybe? I'll need it in at most a month so I probably won't be able to wait. If I waited for the "next best thing" I'd wait forever.

I knew I shouldn't have wrote it that way. I should have said if your willing to wait. I understand completely. I was choosing between a GH1 or the HMC40 but because I had a chance to pick up a GH1 in July and that the HMC40 was going to cost a lot more, I couldn't wait any longer.
 
No problem... I have an HMC40 and a 150... Was going to sell the 150 and get the NX5, but I don't think it'll be a good upgrade. Then I thought about the HDSLR's and that's really the look I'm after. I used to get it from my full size DV cameras with fuji and canon glass (fully manual) so having to focus with a FF and such is no biggie. In fact, I prefer it.

I'm looking for a replacement for the 150 that has that slick bokeh.

GH1 body is $300 new if you buy right and sell kit lens.

So $800 will get you:

a) GH1 + 20mm 1.7+ $100 for hookers

b) GH1 + FD 50mm 1.2 + FD 24mm 2 + $100 for hookers

c) T2i (whatever that is)

It's your choice, I know what I went with...

No hate all love man. :D

And by "buy right" you mean from the back of a van in a shady neighborhood?

Cheapest I've seen the kit go for from a reputable dealer is around $1150 (B&H or Adorama with 3% Bing cahsback).

You could probably get around $600-650 back for the lens, but you have to pay ebay and paypal their cuts, as well as deal with the hassle of selling and shipping.

So best case, around $550 for the body . You might have to skip on those working girls.

I thought this was a thread about getting a T2i as a Bcam for the GH1...now it seems to be low light vs low light performance.

Here is a test thing I shot awhile back with a Canon F1.4 and a touch of noise reduction. In many cases, we're talking...no light. Of course, it'd be better now that I own a noctilux and tripod :D.
 
If I'm not mistaken, the T2i still doesn't do auto focus while filming, correct? I will agree that there are situations where my GH-1 lacks in low light performance, however, when shooting scenes with motion and the subject moving closer and further from the camera, it eliminates the need to pull focus and I find that usually the auto focus does a good job if you set it up correctly.
 
AF is just the 1st thing on the list of why canon dslr's are not good run and gun cameras...

The last thread like this closed... bold to start the debate up again... Again its going to boil down to your NEEDS. I am sure I would be saying canon all the way if I wanted cine/vacation camera and not all ready had event/ENG work on the reg.

For me... GH1 has more features of typical 'video' camera (AF, articulating LCD, long record times), which I find weighing higher in my book than quality, lowlight and codecs (which are all conditional).

As a B cam would be interesting to see... but I don't think it will match up easily...

Anyone working on SIDE BY SIDE yet?

...Well then Mr. MAD let us boldly go where no thread has gone before...:evil::D

You're absolutely right MadHMC150, it boils down to my needs. That's actually really helpful, b/c the GH-1 definitely satisfies a lot of my needs,
but--I am looking for better stills for night time time-lapse
I am looking for a cam that doesn't produce so much FPN or as Martti likes to put it "BANDING" (:laugh:)
I have to admit, for the price point I am attracted to the larger sensor, I know it's not a full frame like the 5D but it's like 30% larger than the GH1.
Am I being blinded by that fact? Am I putting too much emphasis on that? Another words is a larger sensor overrated or do I have legitimate reason for buying into that??

Ohh, and Martti, it's not "BANDING" it's FPN,(Fixed Pattern Noise)
Banding is attempting to perform melodies with the use of various instruments whilst under the influence of aged spirits with my closest of friends in some type of cohesive nature.:beer::beer::beer:
