7d still not working, need help please

[Lestat]

Try a controlled environment test. You can't control the environment outside especially ambient lighting. Plus the shot itself looks underexposed.

I'm sure you have a rubber ducky or some other baby toys. Try with those and use a flash if you have to. Bounced or otherwise.

Your example doesn't show the focusing issue you are talking about. It could just be the ty kit-lens!

And run this thread over POTN and I'm sure some will chime in regarding custom settings and what not!

the poopy kit lens doesnt create noise, and my point of the picture wasnt focus it was noise. and neither does underexposure at iso-100.
the camera also has white pixels and red stuck pixels, and this is the Canon Rep's camera. they dont show up under normal ligthing, it has to be low light, but they are there.

its been run over at POTN and the guys over there are understanding of the issues as they have seen them also.
I also just got off the phone with a sports pro who went thru the same issues as i am, and also 2 bodies and refuses to use another one, he also mentioned the Saracuse News and the AP guys refuse to use the camera also because of its flakey focus.

I have no doubt, as Elisha can attest to, that the 7D can be a solid camera, but my experiences are saying different along with god knows how many forums around the net saying the same thing.

the camera is flawed, canon refuses to acknowledge any issues, and when the canon rep's are faced with unhappy customers they have no problem allowing the person to get a full refund. that right there is worth a million forum posts, when a rep immediately, as the rep did with me, says give him his money back that proves that they know of the issues and there is no fix for it and they are not willing to go thru god knows how many bodies before the customer gets a good one.
Anyone in any type of business knows that when a rep instantly gives up, that is a huge telling sign that the factory knows about the problem and cant fix it.

get the t2i or if they give you a nice discount on the 5dmkII thats the one

[ripken204]

so i am going through some custom settings right now for AI Servo
C.Fn III-3

by default if you are tracking a moving object and another object appears in the picture closer to you, the camera will track that closer object.
i am assuming the AI servo tracking sensitivity plays a role here too but I find this default really really stupid. i am changing mine to stay on the object which i actually want to track...

EDIT:
and according to this
http://www.robgalbraith.com/bins/mul...=7-10048-10484
AF tends to suck if you are shooting an object coming at you (a runner) when you are shooting from even a slight angle

[ridney]

anyone tried the 1.2.1 firmware yet?

[ripken204]

oh wow just released!
i will install tomorrow and test it out!

[Cookiesowns]

Hmm, well heres my take on the 7D.

The 7D with WIDE aperture lenses just doesn't shine that much... ( sigma 50mm f/1,4 ), Have you tried using uhh whats that called, the precise af mode? Sorry forgot the name, but with my 7D it just absolutely produces life like images with my 70-200mm 4L IS, focus is dead accurate. with the 1.4? well... was a little bit disappointed.

[ripken204]

i think you may mean 'spot af'?

[Elisha]

You're judging based on problematic lenses. The Sigma 30mm and 50mm are plagued with AF and softness issues to begin with until properly calibrated!

[ripken204]

and i am still not liking ISO800 or above on this camera..

[Lestat]

hey rip make an ISO thread, i want to see some examples and i will post my similar examples with my t2i
and maybe Elisha can post his 7D ISO tests.

noise is noise and it isn't created from spot, center weighted, or other focusing or metering.
although more chromatic/color noise would happen if it is metered incorrectly, that would be a time where my statement is flawed, i agree.
ie; picture is metered with too slow of shutter speed thus causing ISO noise to be more apparent.

[ripken204]

hmm, i am not quite sure what you are meaning by too slow of a shutter speed in this case.
that would mean that the picture would be a little too over exposed...
in my cases tonight the pictures tended to be a little underexposed, according to lightroom 3 at least.
i was shooting in TV mode.
i guess i should try slightly overexposing the shots at ISO800 to see if i obtain similar results..

it is somewhat hard to see the noise while zoomed out at the whole pic, but when i zoom in to 100% it is very noticeable.

i also shot some at ISO3200, mainly b/c i had no other choice, obviously there is a great deal of noise, ive never shot that high before.
i will hopefully be able to play around and test this out some more this weekend, i finally have a weekend where i am not crazy busy with track meets.

[Lestat]

yeah my words were incorrect i meant too fast of a shutter speed causing under exposure and maybe the iso noise might show up more.

lets do an iso comparison thread, i really am interested in what you are finding bad about the 7D iso performance.

i wasnt impressed with it at all, i wont argue that but i just want to see what you are calling bad and try to mimic things on my T2i

[ripken204]

ya i guess we can do that, maybe i am just expecting too much out of it, but after looking at other ppl's images i am not impressed with ISO800+

[Lestat]

the hard part about doing camera comparisons between us is that we have no controlled subject or environment so we have to do our best to mimic each other.

something like each iso setting at a set shutter speed and f-stop of a similar subject using something like the default neutral custom style in the camera.
but post some of your shots your unhappy with so we know where you are coming from.

i actually say a video once where a guy claimed use iso settings that are multiples of 16, so iso 240, 320, 640, etc.
maybe try that and if it makes a difference.

[Mescalamba]

Aand.. do you use Canon DPP for processing those ISO 800+? Cause if not, thats why you are not impressed.

Btw. Canon doesnt have too good SNR, but! it has very good software ways to handle noise. Kinda opposite from Nikon.. but I think that I will have white beard before Nikon introduce more than 12 mpix APS-C.

[Lestat]

also dont forget to shoot raw, which i imagine you might be already.
but canon doesnt have the iso difference between raw and jpeg like nikon does, but there will still be some difference.

[Elisha]

Are you shooting people or objects at high ISO?
People aren't a good way to judge cause if you don't like how the eyes look, the whole pic fails!

[Elisha]

Camera: Canon EOS 7D
Exposure: 0.025 sec (1/40)
Aperture: f/5.0
Focal Length: 30 mm
ISO Speed: 12800
Lens: 18-55 IS



Had to use such a high ISO cause of the extreme low light but you can see why it is necessary based on exif too....
NRed of course....but this one is acceptable cause his eyes soak up all available light making that area less noisy naturally!
Spot metering saved this shot and properly exposed it!

[ripken204]

Are you shooting people or objects at high ISO?
People aren't a good way to judge cause if you don't like how the eyes look, the whole pic fails!

people, but it's the whole picture..
and i am shooting in RAW.


Here is just one example:
DNG File

and yes, this is one that is a bit underexposed.

Camera: Canon EOS 7D
Exposure: 1/640
Aperture: f/4.0
Focal Length: 200 mm
ISO Speed: 800
Lens: 70-200 f/4 IS

[Lestat]

EOS T2i
Canon 50mm F/1.4 @ f/4.0
iso6400
1/40th sec.
straight out of the camera and resized
shot with Kodachrome style

[Mescalamba]

Quite a lot of noise.. can you post RAW somewhere? I would like to try something. Ideal would be if you convert RAW to DNG via DPP, if its possible..

[ripken204]

hmm, just realized lightroom 3 has a cool noise reduction tool, and it actually helped a good bit

Camera: Canon EOS 7D
Exposure: 1/640
Aperture: f/4.0
Focal Length: 200 mm
ISO Speed: 800
Lens: 70-200 f/4 IS

BEFORE


AFTER

[Elisha]

Do you have shots of anything static?
The runners seem a little OOF.

[ripken204]

i only have 2 shots at ISO800 where they are just standing, not rly moving, same results though.
i wish i had more time to play around with my camera at these meets.. too busy working.
i do agree they seem a but out of focus, 40 degree rainy and windy weather is never a nice thing, but still..
being slightly out of focus should not account for noise.
