Amazing lens, incredible sharpness

Perhaps you read where I asked, "Aside from DOF and noise, why would anyone care about the aperture?" Well?

OK, look, you're obviously very excited about the fact that you've worked out three things most people already knew and took for granted:

1. Larger sensors have less noise
2. The hole on the front of a FF camera needs to be bigger than on m43
3. The hole on the front of a m43 camera doesn't need to be as big as FF

Wow! 0 for 3! That's impressive. OK, here we go:

1. Larger sensors do not have less noise (except at base ISO when they can use a longer shutter speed than smaller sensors before oversaturating) -- lenses with larger apertures (entrance pupils) put more light on the sensor for a given shutter speed, resulting in less noise for a given sensor efficiency.
2. The hole (aperture -- entrance pupil) of the lens does not "have to be bigger than on m43" than on FF, but it generally is for lenses of a given AOV, and that wider aperture is what results in FF having less noise (and a more shallow DOF).
3. If the hole (aperture -- entrance pupil) of a m43 lens were as wide as the aperture on a FF lens of the same AOV, then the m43 camera would produce photos with the same DOF and same noise for a given shutter speed.

In a nutshell that's it. It's not a secret, you've not discovered Atlantis or found the cure for cancer.

Yep, you're absolutely right -- it's not a secret, and it's not like it takes an Einstein to understand it. Except you didn't know it, and *actively* resist understanding how things actually work.

I understand that when you work something out for yourself it's all very exciting, I can still recall the time I realised the PS3 remote was bluetooth and I didn't have to point it at the PS3 to get it to work. Very cool! Though 23 minutes later the wife got bored of me running to the kitchen, the toilet, outside pressing pressing the buttons and shouting to her to see if it's paused or resumed and took the remote from me until I'd calmed down.

Unfortunately we can't do that with you, all we can do is ask that you stop jumping onto peoples threads and basically spamming them with your "discovery". You've been doing for going on two years, maybe you could start doing it on another forum? Perhaps the Nikon 1 forum? They've an even smaller sensor!

I love self-harming posts like yours. Please, keep them coming!
