NEX 7 at 3200iso

[argieramos]

Live view do actually cause a lot of heat that it's effect is able to be seen on pictures.

So does that mean that since SLT cameras are continuously using the sensor to display the image on the EVF will inherently have noisier images? I guess that would explain a few things...

Don't SLTs have optical viewfinders?

EDIT: Seems like they don't have any optical viewfinders. Thought that the mirror reflects the light to the optical viewfinder before this, but realised its for the autofocus array. This is kind of a stupid design - you lose the optical viewfinder for a little better autofocus? No way. Heat build up on the sensor due to live view and the loss of light from the mirror are the main cause of noise.

Sony has a different approach doing their LV compare to Nikon and Canon. It is superior and faster than Canon and Nikon

Your opinions don't make any sense. The high ISO of the Nex looks really bad. It looks the same as my 60D at 5000 ISO. And the 60D is even worse than the 7D so....yeah....

Your claim means nothing if you can't back it up with proven facts. I have been putting my evidence on here and my evidence show how inferior Canon sensors are

But you aren't. The ISO doesn't look good on the NEX. Yes, you've put evidence up, but they don't prove your point.

How is that not proving my point? It proves the superiority to the Canon 7D in every category. I shouldn't expect that you will accept that. Like you said before,you're biased against Sony. You even made some false claim like a77 is using Contrast Detection AF. lol

You may not like the ISO performance of the NEX-7, but that doesn't change the fact that it is wayyyy better than any APS-C camera of Canon in the same ISO.

That's the main reason that I was turned off by SLT's. They're not very practical IMHO.

I am biased against Sony. Their first DSLRs were pitiful. And I never said that they used contrast-detection AF. I was saying that they had a little annoying sensor right by the eyepiece that would autofocus when you put your eye up to the viewfinder, and it would never lock focus because of this.

The 7D has better processor technology, better autofocus, and better FPS. The NEX is a consumer DSLR that is designed for the on-the-go consumer.

Canon 60D
24mm
f/8
ISO 6400
Noise Reduction Disabled

These images have the same quality of the NEX at ISO 3200. So I assume that the NEX has pitiful ISO 6400 quality.

This is exactly what we've been saying this entire time. And the AF isn't necessarily 'better', it's just able to use the phase detect full time... which is great if you're a videographer, not so much if you're a photographer.

 

[erotavlas]

Say what??

Live view makes the camera hot, which increases noise level.

That's the theory, but in practice the effect is marginal unless you use your live view for hours non stop.

Looks like the effect isn't marginal - even after using live view for less than an 1/2 hour

Photo Cornucopia

And I told you that feature is turned off by default settings. Did you turn that thing on then forgot how to switch back off? Common sense buddy, something like that can be disabled. Even with the "eye-start", you can always re- focus, but you didn't know how to do that. You couldn't even do lock focus which is a very easy task even for the a100. You didn't know how to operate the camera.

So you didn't say a77 using a contrast-detection AF. haha!
a77 focusing is not based on contrast but rather phase detection.
This will prove you wrong. A77 focus faster than the 7D in low light.

NEX is not a DSLR, just to let you know. As I said before, 7D is overall better camera than the NEX-3. Better ergonomics, control, OVF, etc. But the picture ImageQuality is inferior to the worst,cheapest NEX of Sony.

Canon 60D
24mm
f/8
ISO 6400
Noise Reduction Disabled

These images have the same quality of the NEX at ISO 3200. So I assume that the NEX has pitiful ISO 6400 quality.

You are only looking at the noise level which I see the difference is not that big. But the picture IQ is inferior to the NEX-3. Here is my evidence

If the result is better than Canon camera on the same level, why complain? That's what I have been saying this entire time.

Turned off? You actually considered an alpha before? You are not happy with your Canon my friend? lol. I won't blame you. Canon camera takes picture not as good as other brands

Sony Forum:
Canon trolls: Sony cameras are so noisy on high ISO, bad IQ, bad camera, and slow

Me: But Canon cameras perform worse <show evidence>

Canon trolls: (Holy $h!t, he's right. Canon cameras IQ looks crap in comparison) Well, it's not about the sensor, it's about the photographer.

Me: lol lol lol lol lol lol lol

No love for Canon?

I do agree with KenRockwell in this statement, but never trust his site, unless you know what is right and what is wrong (then why are you still reading it?), its a joke.

I'm happy, and there have been photos taken by Canons (and Nikons) on this site that are indeed better than your photos, even though you have the God camera, so as far as I can tell, you can keep taking high detailed pictures of your cats while everyone else gets on with their lives. Agreed?

At the same time there are also photos taken by Sony cameras on this site that are indeed better than Canons and Nikons. Take your photo as an example. Looks really bad. Again, photographer makes the difference. But the fact remains that the 7D and your 60D IQ is inferior to NEX-3

I am not saying your 60D is not a good camera. All I'm saying is that the Image Quality is not as good as the camera that you are bashing. That's all bro.

PS. lock-focus is a very simple task. You should have somebody to teach you how to do that. Very simple

Why isn't argue banned yet? Hes just a troll and doesn't add anything.
