Why doesn't Sony use smaller sensor surface advantage from NEX system to build f/1.2 35mm lens,  and 85mm f/1.4?

I've been wondering about this for ages. Been getting a whole lot of defensive answers here, as if the people who visit this forum and own a sony camera also work for sony and try to discourage people from asking this kind of questions.

If it helps you out, the oss on the sel35 and the sel50 make them in some situations even better than a faster lens. But sometimes all you want is a faster lens. And it ain't there.

Another option is a faster manual lens.

Yes it would cost a lot and yes it would  perhaps be a lot bigger, but still, it would be nice to at least have the option.

Nikon today announced a 35mm 1.2 lens for their 1 series. Yes the nikon 1 has a smaller sensor, and yes that lens is going to be 900$, but still, people who want it, will be able to get it. People wondering which camera to get will hear about the 1.2 lens and go for the nikon 1. Sony just doesn't seem to care.

Go buy a Fuji X, they have a 56mm f/1.2 coming soon.

Sure, I would like to see a few modern large aperture lenses for small sensor systems, but currently I think f/1.8 is a pretty good balance for APS-C.  It keeps the lenses modestly sized and affordable, and usually don't shoot at f/1.8 anyway.

Edit:  My point is since it is a small 1" sensor, the Nikon 1 has to have f/1.2.  APS doesn't really need f/1.2, sure I would take a few nice f/1.2 primes, but then you lose size and cost so I would just buy the 1.8 primes instead.

Eric,

I honestly don't buy this, f/stop is relationship between lens external element diameter and distance to the film/sensor. By looking at tiny external lens elements of f/3.5 lenses I always wondered why makers prefer doing these small and dim lenses.

Olympus is capable even having f/2.0 zoom lenses, and Sony is not...

Person is taking photos, not camera. When photograph is bad, it's because photographer doesn't know how to choose settings optimal to "own preferences". Then blames camera for bad IQ.
This is same as blaming car about arriving to wrong destination.
