Ok thanks so why dont oems make like a f5/0 sensor?

Higher the aperture translates to more light entering the hole of the camera, which translates to better picture quality even in low light. The shorter the focal length means the thinner the phone will get, and of course if the shorter the focal length of the lens means it would be able to capture a wider angular field of view as opposed to longer focal length. And that is why you noticed that Samsung camera focal length is short, but the magnification power is really compromised, as the advantages to longer focal length translates to higher power of magnification. So it's up to you, whether you want a longer camera but with higher amount of magnification which is the pure view, you can see the camera just pops out like a extrusion popping out of the phone, or you want a slimmer body like the S3 which I bet it would be slimmer than S2 but with a low magnification power but of course with a wider angular field of view.. Sorry for the long read, most of you will not read all.. but thanks for you time..

Focal length is the distance between the lens and the sensor.

Aperture size is the opening of the "lens hole" that lets in light.

So he's right, bigger aperture, lower focal length is better if u want lower f number.

but not always possible.

download ICS now..kinda slow..server traffic jam maybe

thanks for the explanation
where to download ???
hope G unit ICS fast release ><

intratech xda..

f/5 has a aperture to focal length ratio.

Its length / aperture size.

Not aperture/f-length.

We're looking for a smaller f-number.

so f/2 is actually very(very very) respectable already.

Are you sure?
because magnification depends on the distance of object to the lens.
And we're not really talking about magnification here, we're talking about f-number.

Ok i think i get it now thanks, so f/1 will be better than f/2?

I went to samfirmware and download the XXLPQ, but is it the official one?

No its not,I made that ROM two days ago in my sleep when I was in Hogwarts

Yes, f/1 will allow more light to hit the sensor than f/2 for the same given amount of time the lens aperture is open.
Example:

If the aperture is open for 1 second for both f/1 and f/2 lenses, assuming both are open at max aperture setting.

Picture in f/1 will be brighter than f/2.

This is useful mainly in low light conditions.

But sometimes in very bright conditions this may be a drawback as the shutter speed can only be that fast.

This sucks right? hahaha...

When you think f/1 is better than f/2.

Until you realise that when background light is so bright your picture loses all detail, then you want an f/5 lens.

LOL i love ur reference to hogwarts

hi,
direct download for ics rom is very slow.

use the torrent in this link, i read comments in xda is very fast.

Seriously, I've only been in this thread for one week, and I feel like assassinating him already...-____-!

I know, pretty much everyone here does.

Since he so rich got w,note and 2 s2, hopefully he go buy s3 and go be annoying there, and finally in months we'll have peaceful thread free of annoyance

Ok i get it now, needs to be just right, cannot too much or too little. Thanks agn
