Alexa LF

Nice 4.5K sensor.

And from their Q&A...literally the second question on the list ahead of more important ones, lol:

Q: Is this camera Netflix compatible?

A: Since the camera has a resolution of more than 4K, it should be Netflix compatible.
 
The Arri cameras are pretty much the Gold Standard in image for Hollywood. So I doubt if this new camera will be much more than a higher resolution version of what makes them successful at this point.
I spoke with Arri this morning, hopefully I will be getting hands on one to review and write about.
 
New lens mount, LPL, and resolutions including 4448x3096, 4448x1856 and 3840x2160 so Netflix should be happy.

How do I feel? Cool! Maybe it'll make "regular" Alexa and Amira rentals cheaper. Not sure I'll be rolling 4K Arri... sure, would be fun but this will probably be out of my league for at least a while; I don't do Hollywood stuff. At least for stuff I produce. And RED, Canon, Panasonic 4K isn't so bad...
 
When they say slightly bigger than full frame 35mm, they really meant it. I wonder how many FD and EF lenses would cover the very slightly bigger sensor. Seems like there could be a lot of glass that may function with this camera. I bet a bunch of these adapted lenses would work just fine at 16:9 crop and probably at the 2.39 crop.

Can you even adapt those lenses to this camera?

Worst case scenario if you can adapt those lenses is that you crop your video in post if those lenses don't fully cover, which shouldn't be an issue considering it's already a larger non-standard resolution.
 
It might be tight, but it says it has a 44mm flange length which just happens to be the same as EF, so if an EF to LPL disk adapter can be made, then it would seem that FD with EF mount change, and EF, and Nikon adapters might be able to fit. I guess a good bit of this will be if other manufacturers start using the LPL mount for their cameras. Something to consider.

Now if the LPL mount can be removed, then it appears that a lot of different mounts could be created. Hard to say until someone has this camera in their paws and takes a good hard look at the mount. You'd probably lose any lens data, but for some people that stuff isn't a huge issue.
 
Arri keep it simple - jamming pixels into s35 area compromises that Alexa look.

But this lens mount - I wonder if it has data for auto focus.

Arri seem to be pedalling hard but canon af getting it right sometime could compromise them I guess
 
At minimum one must record all lens data to replicate camrera moves in the virtual world.

(This may happen?)

As for getting true focus at 5k on a 1080 monitor.. Well it is not possible.

Anyone not interested in af is way more stupid than Arri.

Haha Cooke-i and LDS have been capable of that for years. And guess what- the plugs are not connected on ARRI cameras- at least the ones I have seen. So no, at least not yet anyone cares about the lens data.
5k 35 size sensor is not resolving more than film, especially after olfp, debayer, a to d conversion and compression. And film focus has been dealt with for years, successfully I might add. Anyway there is such thing as punch in or pixel to pixel viewing mode on all digital cameras so the focus puller can see exactly what camera is seeing. Stupid- I don't think so and the market seems to agree. More like not being drawn into consumer gimmicks. When the AF can follow the eyeball and read the brain of the DP we can revisit this topic ;-)
 
There are quite a few sources:
4K film scan VS 2K film scan tests done long time ago, lens resolving power for film VS pixel pitch for 5K S35 sensor, "MTF " of OLFP, return of resolution after debayer, S/N ratio after different bit depth a to D conversion, compression schemes and their effect on final display resolution, etc. I would have to write a book here on this subject. Oh yeah and the fact that on certain 4K digital cameras I tested with a reticle that had 4K target on a S35 size frame I could only see into about 2.5k worth of line separation. So I know that for a fact.
The fact of the matter is that a number of pixels on a cmos sensor is just that- a number. It definitely affects the picture resolution but it by no means defines it... Arri knows that better than anyone currently, and takes full advantage of this knowledge...;-)

Apart from the fact that this segment don't demand or want AF, you're forgetting the fact that Arri also earn plenty of income form selling MF lenses and focus accessories. Why would they spend lots and lots of money developing a feature very few (if any) users are actually asking for, if they're only going to lose income because of it?

I agree. If anything, the Amira would be a much more practical camera to build-in or license intelligent contrast-based AF using Canon lenses like the CNE Servo models. Alexas live in the feature and high-end episodic world where it will be many years before anyone is excited about any kind of AF.
 
Lens wise - how long are cine lenses supposed to last and more important create a return? 10 years I guess at least - which is why a new lens mount needs to consider the deep future

The cameras less so.. they are the cheap disposable bit :)

I don't know about reading the DP's mind, but you can bet pretty soon camera AF systems will be able to successfully (and smoothly) track a person's eyeball.

That said, the Alexa LF and the Signature Lenses look fantastic. Any idea how much they'll cost? (I know, I know. If I have to ask the price...)
