It's normal, not specific to a new camera...

@PK24X36NOW
In the past, Nikon have made the Nikon 8000ED scanner (and 4000ED for small size) for 6 x 9 cm format with 4000 dpi.
So I think, when adding this function, like drawing a snake with foot...

@turbsy
I think, at the present time, the only films they still use are in 4 x 5 inch, not in
24 x 36 mm (to use the D850 to scan them).

If the price is under $ 500, maybe there's someone think about for a pocket camera...

The problem is that... no one use film anymore,
With the old films, almost have been scanned by flatbed scanner or drum scanner. So they have no chance to do it in the presence...

I think, in normal users, no problems with this phenomenon.
The information is very useful for anyone want to saying in coffee spaces...

On article CP+ 2017: Hands-on with new Voigtländer E-mount primes (117 comments in total)

While we pay money for performances, I don't know why the manufacturer doesn't have questions about that. Or he cannot do that...
I will use manual focus if I want, but I also want to have accurate AF function in the lens...
The film makers usually use manual focus but they won't use this lens.
The quality is only one of other functions that the users need.

Nukunukoo: Dear Cambo, can you also do the same for X-Mount? Much appreciated! =)

Not the quality, but the price.

On article Olympus working on 8K video for Micro Four Thirds (219 comments in total)
In reply to:

trungthu: If the dimension of the Olympus's sensor is 18 X 13,5 mm. And when they make a sensor for 8K, that means 18 mm / 8000 px = 2.25 um per pixel.
And I think with that pixel dimension, Olympus can not say anything about the detail or the dynamic range of the picture or motion picture.
The lens can not "see" that so tiny pixel... or they must use software to reproduction the detail. Not the real detail from the sensor.

I don't know you want to say about the "number" of pixels in a sensor or the "quality" of the picture using that tiny pixel pitch,,,
Someone has said about the quality of the Nokia (41Mp), maybe 7 pixels equal one pixel in a normal DSLR... (when saying about the quality of lens plus lens's resolution...)

In reply to:

trungthu: M6 is good.
But I don't know why Canon don't (or can't) go to fullframe.
While Canon user's fullframe camera wait for... with all fullframe lenses they have had...
Canon was too late to Sony...

Thanks with same feeling...

Thanks, I'm saying about mirrorless, not DSLR. I hope Canon go to fullframe on mirrorless camera, I have used Canon 5D, 5DII...
At this time, almost Canon go to 4K motion camera, so they don't care with mirrorless fullframe...

trungthu: I cannot see the color bit depth of this camera in this announcement...
They (Pentax) forgot or it only has 12 bit?
With K20D, they have said about the color bit depth of 22... ?

Thanks so much, I have just seen.

Please show me the link to know this color bit depth.
Or you say it by yourself's thinking...

trungthu: I don't know Fujifilm used the anti-aliasing filter or not. The sensor is X-Trans or not, and I think it is not.
While almost all of medium format digital back has 16 color bit depth. Fujifilm GFX 50S only has 14 bit in Raw (and I think 8 bit in TIFF). Very low level when compared to normal medium format digital back...
In this case, maybe Fujifilm goes behind Pentax in medium format...

Thanks chriswy... for this information...

In reply to:

IdM photography: Maybe such a sensor, mounted in a FF type body, would offer the possibility to choose between 3/2 and 4/3 aspect ratios with a similar resolution (but not the total 48M resolution, naturally, as it exceeds the image circle of FF lenses)

The image circle of this sensor is only 45.71mm, not exceeds any full frame lens.

In reply to:

trungthu: If Canon uses it in the first full frame mirrorless camera... I think it's very impressive information for the next year to develop the "high-end mirrorless camera" market...
I think, with this sensor dimension, almost all the L-series lens can have enough covering power to afford it...

I know that.
But Canon can make his own sensor...
