This is good news because the sensor technology has area to improve more. I expect the technology will be adopted to other models.

I was surprised that Goto was a leader of Df but mentioned that he was not satisfied with the Df in the article. Many Df users or customers waiting New Df will be disappointed.
I am D750 user now however I will not buy any Nikon body if Goto's attitude is entire Nikon's sense. Who want to buy any products which Chief engineer of the model is not proud ?

In reply to:

theongu: This article is incorrect about bit-depth math.

The count of all the possible values is the denominator. Any value represented by those bits are the numerators. In an 8-bit number, there are 256 possible combinations. The possible values are 0/256, 1/256, .... 255/256.

It is true that 1/2 of the range of values represent the brightest stop; and the next 1/4 of represents the next brightest; and so on. It is NOT true that additional bits only enhance the shadows. Additional bits in the file refine the gradation throughout the range (within the sensor's limits).

For example:
An 8-bit value 00000011 and a 9-bit value 000000110 represent the same intensity in their respective number space (3/256 = 6/512). Now a 9-bit value 000000111 is a little brighter (7/512). This is in the range of "shadows".

This is also true for "highlights". An 8-bit value 11000011 is the same as this 9-bit value 110000110 (195/256 = 390/512). A 9-bit value of 110000111 is a little brighter (391/512).

Hi theongu, thanks for this explanation. I use D750 with 14 bit raw in general because I feel gradation from light to mid to dark is very smooth, which resulted comfortable three-dimensional image. I do not mind far highlight or dark part out of DR because it is not important for my shot in the scene. I will continue to use 14 bit raw.

SmilerGrogan: Doubleposted

I like to see more reports/reputations that this strobe will not damage camera body electronically before I make decision to buy.

YorkM: It is nice excuse that delay of supply is caused by more orders than planned. However, I reluctant to hear the same excuse many times. It is no more good marketing method to limit supply to keep price. Canon is too much confident not to lose customers to other brand.
For Nikon D5, they should be shame not to supply by the anniversary time. I cannot understand the delay because its special edition but base D5 is there.

badi, Thanks again for deep insight. I did not imagine that kit is a special package.

badi, thanks for your explanation. Then, it is not an issue of 6D II body but limited supply of 24-70/4 lense. Canon should be very happy to get newly entering FF customers more than replacing ones. If there are replacing FF customers from other brand, 6D II will take very good share in the FF class.

I am familiar with the size and weight of DSLR, therefore, I do not require the mirrorless if the merit is size and weight, but sacrificing the use of current DSLR mount lenses.
If Nikon or Canon makes full size mirorless, the change of mount is unavoidable to achieve the best balance of body and lenses with competitive EVF and continuous AF performance as well as reasonable lens line-up.
If this is realized, I will switch to the full size mirorrless completely, but it may take more years. And the winner will be the manufacturer who can include additional value yield by mirrorless technology.

On article Looking back: Canon's eye-controlled focus (223 comments in total)

I had EOS 5 and 7 with eye focus. It was an ideal function to select AF points with keeping same angle even for moving subject. The weak point was if you do not see the finder strait, the sensing tended to pick wrong point.
Nowadays the AF points are more than 100 and covers 80% of finder, I think the Eye focus is suitable function more than ever. The new technology may help the accuracy of eye selection. If it is realized again, I will buy the camera.

On article Ask the staff: electronic or optical viewfinder? (890 comments in total)

For full size, OVF is good enough. Then, for APS-C or M4/3, I need EVF for larger finder image because I am getting old and feels tough to see small finder.

Regret that no exif data were available. I wanted to know f and speed and iso.

I have a big question for Panasonic and Olympus new lenses. Especially for Lumix, it is more focused to movie than still, which is OK but why Panasonic is fading out the Power Zoom Lenses. It is not only for new lenses but also firm up for Dual IS.
I believe Power Zoom is very important to take smoother video. There may be techinical difficulties to have Power Zoom and Dual IS but I hope they will find a way soon for video shooters.

On article DPReview Asks: What was your first camera? (766 comments in total)

My first camera was Canon FTb+FD 50mm f1.8 in 1970 whose price was about USD500 (current rate conversion) that time. It was my high school age and my parent bought it for me. Later, I purchased FD135mm f2.5 costed USD300.
I had used it for 15 years without any troubles, thanks to its simple construction. I still keep it for my memory. I had traveled with it from North to South in Japan because I am a railway photographer.

Especially for Mirrorless, Canon added EOS-M just filling line-up without putting the best effort adopting Canon's High Tech even though Canon was late comer in this field.
Other Mirrorless brands have been introducing various new technologies which should enjoy the mirrorless character and overcoming the weakness to DSLR rapidly.
The new EOS-M5 looks it is catching up the competitors, however, competitors are moving forward, while I have no idea of next EF-M.
Canon had to more serious to introduce their mirrorless and same thing is happening to Nikon 1 series.
If the lenses of APS-C mirrorless are compatible with DSLR, customer willing to have DSLR and Mirrorless in one brand, however, it is not realistic from technical point of view. As a result, I have a Nikon DSLR and a Panasonic Mirrorless because I needed to buy different body and lens anyway, for serious use and casual use.

On article Modern Mirrorless: Canon EOS M5 Review (1648 comments in total)

For M5, especially for video shooting, Canon should prepare the lenses with Power Zoom, for smoother scene zooming . I hope M5 body is ready for the power zoom function.
Canon shuold extend EF-M lenses line-up incliding power zoom lenses.

I am reluctant to see such extreme lab tests. I do not think there are many chances to push 3 or 5 EV afterwards because the camera's auto exposure including auto ISO function is very smart now.
I want to see real scene photo comparison at low ISO with proper exposure.

Apart from the cost and image quality discussion, if I use this product, I will have to convert the film output to digital as soon as possible because it is very difficult to store film in a good condition for long period.
Its digitalization will be also convenient to put sound and share with other peoples,
How about a projector for the film ? I donot know it still exists.

Even this is a proto type, I donot think this concept is a good idea.

I bring a Nikon D750 for still and a Lumix G6 for video to shoot a Steam Locomotive. I hold D750 in hands and put G6 on a tripod.
If 8K video and 33mp still are available at same time and its AF tracking speed is very fast, I would buy one.
I guess Sony may be thinking same way as Panasonic and Canon or Nikon will stay still focused cameras.

In reply to:

PaulinAussie: This is probably due to Canon's sensor performing badly. So many shooters are leaving Canon.

See the sensor rating below:

http://www.dxomark.com/Cameras/Ratings

I agree and that's why I have changed from Canon (5D) to Nikon (D750) with all lenses, which was a very tough decision.
And I am satisfied with the results now.

The M9 owner was lucky because it is a range finder, otherwise the mirror related parts might be damaged. Also, the owner put case on it without caring how it is inconvenient to see the picture and setting by rear display, or the case may have a rear screen see through function.

You will know the damages on electrical parts soon.
