On article What difference does it make? Sony uncompressed Raw (621 comments in total)
In reply to:

manewsom: I am suspicious about the 14 bit firmware fix. The 14 bit file should still be 1-bit per pixel and the file should be approximately the same size, not twice the size. Sounds like Sony simply gave us files with the same data repeated.

This is a mixed issue. Its not just 13 vs 14 bit, there's also the lack of compression as well.

I'm still not sure how focus adjustments are made in the lens firmware/rom data. Focus is achieved with a feedback loop via the phase detect sensor and/or contrast detect.

camera: *samples focus point(s)*
camera: Lens! Advance focus by -this- much
lens: ok, done
camera: *samples focus point(s)*
camera: err, you didn't quiet get there, shift focus by this small amount
lens: ok, done
camera: good enough
camera: *releases shutter*

Is the whole point of micro adjustments in lens firmware/rom intended to get the first focus movement to be more correct with less fine adjustments after that?

Why was this even an issue back in the day of non electronic 'dumb' geared lenses?

The lens doesn't know its in focus, only the camera does., even with the fanciest electronic lenses.

Jim Evidon: Back in the good old days of rocket research, we used to rely on a high fps rate camera called a GSAP to study rocket engine firings. It's total running time was a matter of seconds. It cost a fortune then.

Now there may be one for less than $700? What possible use can an amateur
photographer have for such a device once he has taken a picture of a hummingbird in flight or a bullet shattering a light bulb? It's a marvelous achievement in price vs. performance, but it's long term use to the average photographer will be in bragging rights only.

Someone said he'd pick one up in a heart beat. And do what with it? Do you have any idea how quickly it will fill a 32GB card at 18.500 fps @ 2560 x 2048 pixels per image? I would imagine we are talking in terms of seconds.

It has a profound scientific future and I cheer for the inventor, but aside from that who in amateur photography needs it? Who will want one is another matter.

This is what's always said before a new product comes to the consumer market.

Perfect lenses are really boring. Maybe for scientific work.

Ha. These are just using the QD(quick disconnect) system for rifles.

The GH series really needs to be able to record 422 10bit or better internally by now. Sony is behind here but still they should be able to as well.

So its been over 8 months since this article. Assuming they started work before this article was written, it doesn't take that long to add what is essentially a 'basic' feature as it doesn't require any post processing. Where is this?

'Flat' video color is a step forward but for this class of camera you really need 10-14bit linear color(raw or whatever) video.
