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...

When someone says "F2" that means "the aperture number is set at... 2".
If one says 1:2 in near the focal length of the lens, that means the number of "the largest aperture" of that lens.
I want to say that "YONGNUO is not a professional lens manufacturer".

Very impressive function...
I hope in a near future it will appear in normal camera...

trungthu: I think, this will be a fault strategy from Fujifilm like as with S5 Pro in the past.
- If they want to go bigger, why unchoose full frame - with reasonable price both in body and lens, and with the popular customers.
- Why they don't choose X-Trans sensor for this camera be the latest model of this line of mirrorless camera. Maybe they only want to show the possibility in camera maker in their weaker position.
- If they can produce a full frame mirrorless camera with the price about $2000 - $3000, maybe they can be a market partner to oppose to Sony in this market place.

- Canon and Fujifilm made their own sensor, not bought from Sony. X-Trans was made from Fujifilm, with differences from others.
- Canon go to full frame very early (maybe the first one). Not a special product from Sony.
- When choosing medium format market parner, this is a new, very new market to Fujifilm, when comare to Phase One, Leaf, Mamiya, Hadselblad... No one can say anything a bout that.

"It provides a minimum focus distance of 16cm/6.3in and is resistant to dust and moisture. Its design includes 8 elements in 7 groups and a rounded 7-blade aperture."
""Optics
Elements 8
Groups 8
Special elements / coatings Extra-low Dispersion glass""
I think, there's a mistake here.

On article Crossing the Bridge: Canon XC10 Review (260 comments in total)

""... Unlike the RX10 II/III and FZ1000, which are aimed at stills photographers, the XC10 does not support Raw image capture. Also, the XC10 is by far the most expensive of the three with a retail price of $2,499 (though street prices hover around $1,999)....""
I think, when Canon choose this price for this "camera", maybe he want to show the high grade of his technology, but not relates to the market place.
When almost all the producers turn the 4K to "popular" in cheaper camera, Canon in the opposite...
Maybe in nest year, the 6K will be popular, and the range of "still" and "motion" camera is disappear... I shoot in motion, and cut any frame to have a 20mp for a still...

Thanks for your reply.
But have you seen "the best quality" from this camera, or only "seen" through what the producer said?
Have you seen the MTF table of this lens on this camera?
And the "best quality" is very different from each one... relates to the their usage...

trungthu: I think with that specifications, the price should be around $2000.
If I want to have a pocket one, maybe I will choose Canon M3 with 22mm, f/2. More cheaper with the quality of image is also OK for almost popular photography need.
If I want to have a quality camera with more performances, I will choose A7R II with interchangeable lens...

I think this function is not useful (parallel control and Scheimpflug principle in tilt control).
The software do all of it in a very easy way.
So the price is not meaningful at this time.
With the professional photographers, maybe they will choose medium format back (also camera) to have more resolution.

On article RX aeternus? Sony Cyber-shot DSC-RX10 II review (271 comments in total)

"Equivalent aperture range", I think this is about the Depth Of Field only.
Not equivalent about LIGHT.
F2.8 = F2.8 (not = F7.6).

trungthu: The price is too high with a new unknown brand...

I's so sorry, I've known this brand for the first time. Even I've taking photos in professional field from 1983.
Maybe I have a narrow eye. Thanks...

On article Otus Readings: the Zeiss 85 F1.4 Otus Comparison (224 comments in total)

I imagine, if comparing in quality, why you don't use Canon 85mm f/1.2 (equal in quality and in price a little).
Use a cheap one to test to a very expensive lens from Zeiss... is it a good test?

- If this lens has only 3 elements, I think there still are many aberrations in it.
- With f/2.8 and at the focal length 100mm, the price should be under USD 500, it can be sold...
- The bokeh is very impressive, if it only relates to the mechanic of the iris steel made, why almost all of Japanese Lenses do not have like this... and the price is very unreasonable.

Very impressive. They all will bring 4K video to daily life users.
From Panasonic GH4, to LG G Pro 2... I like it.

""" The outstanding 60x Optical Zoom allows photographers to capture more intimate shots and get closer to their subject, ensuring that images taken from afar retain impressive detail and accuracy.With the option to operate the zoom at double speed, or to go directly from zero to 60x zoom,..."

We should write: ... to go directly from 1x to 60x zoom...
Not from zero.
