On article Canon announces the XC15 4K video camera (155 comments in total)
In reply to:

eno2: Another D.O.A. from Canon!

The fact that they release a successor to the XC-10 most likely means that it wasn't such a big failure as you suggest. Maybe not a success, but definitely not a failure either. If the market doesn't want a product, you simply stop producing it.

Tal Shachar: Canon 80D is 24MP APSC sensor 1,200$
new Canon 5D mark IV is 30MP FF sensor 3,500$ (3 times then 80D)
so for video shooting Full HD or 20MP still pictures it seems that i'm getting the same size of pixels and quality in both cameras.
so the advantages of this new 5d mark IV camera is only if I shoot 4K video or 30MP still pictures. So i'm just getting larger pictures and larger video size.
I'm not getting better quality (larger pixels) in new camera compare to 80D.

and yes i'm aware of the internal GPS i'm getting in the 5D mark IV and some other few features. compare to the 240$ GP-E2 external GPS I would have to buy for the Canon 80D

I know what crop means, and I certainly didn't use it in the sense of 'downsize'.

Najinsky: So top feature from the announcement headline is the ability to take selfies. At least they get points for consistency by offering it in pink.

On a more practical note, with the welcome rise to 24MP I hope they tweaked the AA filter. On the A1 I feel the AA filter was a touch too strong, meaning the choice between bayer and x-trans 1/2 was to sacrifice detail or accept some artefacts (for those bothered by such things).

With 24 MP X-Trans 3, on what I've seen so far, I feel the combination smaller sensor pixel, and more data points has led to a much better interpolation, meaning better detail and fewer artefact. I find it very impressive.

That leads me to wonder why the need to now offer a 24MP bayer camera, as it's also on a camera designed for selfies, could it be an slight admission of the existence of the 'waxy' skin effect? ;)

I'm pretty sure that a standard Bayer sensor is cheaper, which is why they use it in their least expensive camera. Entry-level models are all about cost-cutting.

Henrik Herranen: "but if your troubled"

My troubled what?

As a non-native speaker of English this kind of trivial mistake mystifies me time and time again. How does it happen? I can understand the confusion of it's/its, because it's genuinely difficult. But how can their/they're/there, you're/your/ur, here/hair/here etc ever be mistaken?

My theory is that only native English speaker can and do make these mistakes. Foreigners learn the words in a different way, and while they do mistakes based on their own language background, I'd be very surprised if a non-native English speaker would make one of these mistakes.

As a non-native speaker, one usually makes an effort to get it right, to avoid mistakes to the best of one's ability, while native speakers perhaps are more careless. Mistakes commonly occur when one is doing something that one is very familiar with, and that requires little conscious thought.

CameraLabTester: If and when the hot shoe appears on future model upgrades... then you know Canon is getting really serious for this mount.

But for now, let the throttled features begin...

.

The Sony A5100 and Panasonic GF8 also lack a hotshoe, for example, so it's not like this is a Canon thing, like you seem to suggest.

rialcnis: Canon, the company, turned me off years ago, mostly because of terrible photo printer support. People that push Canon as the best cameras often have a smugness that annoys me. Nikon too has annoyed me. In still film cameras I was 100% OM.

IT's funny how smug my late father in law, super engineer, art photographer, painter, was, about Olympus, who gifted me an OM 1 on release and brainwashed me against Canon, Nikon, etc. (I just wish OLYMPUS would do a better than Sony a7sIi low light, full frame, 4K, OMD markxxx.)

So i'm glad the rolling shutter is bad.:)

This thread gets the go-off-on-a-tangent award.

"ONLY if you reduce the resolution will the photon shot noise be any less !! If pixel size is same then how can shot noise be diff on per pixel basis ?"

Not on a per pixel basis, but on a per image basis. Remember that shot noise is a statistical fluctuation of light itself. The larger the sensor, the more light you collect, and the stronger the signal will be relative to the noise.
If two images taken with same-size sensors of different resolution are output at the same size, shot noise levels will perceptibly be the same. They don't change much with the pixel size. It's the sensor area that's important when discussing shot noise, assuming that we'll output the images at the same size.

"a cropped 30mp down to 20mp size the pics surely will be very similar or the same, no ?"

Cropping an image after the fact is not the same as taking the image with a smaller sensor to begin with.

Michel, that's true, but in this particular case I think all the expressed opinions really ARE equally valuable and valid. It's just a matter of personal preference.

In reply to:

left eye: So this dual-pixel sensor has 60MP photosites but a 30MP filter array.

In terms of noise, averaging 2 pixels will just about half visible noise.

In terms of dynamic-range the photosites are those of a 60MP sensor, so DR will not be great. I don't think averaging the result from two tiny photosites doubles DR, a blown highlight is a blown highlight.

On-chip ADC helps, but one wonders how down-scaling the 5DSR 50MP to 30MP would compare?

In many ways the 'dual-pixel' sensor of the 5D IV could be a 'single-pixel' 60MP. I'd buy the 'single-pixel' 60MP - with on-chip ADC, in an instant.

Also, it's incorrect to say that "DR is from empty (black) to full (white)". It's the range from the saturation point to the point where the signal is drowned by shadow noise (and there is always noise). That point has to be defined, and DxO for example defines it as the point where SNR is 1:1, i.e. 50% noise. The practically usable, photographic DR is never as wide as that, though.
Increasing the DR is a matter of lowering the shadow noise.

The 80D has better DR than the APS-C models that don't use Dual Pixel sensors, despite its 48 million photo sites. No reason to expect the 5D MkIV to have worse DR than the FF models that don't use Dual Pixel sensors, then.

A larger sensor will certainly give you better image quality even if the pixel size is the same, for the simple reason that the sensor collects more light. The more light you collect, the less you will notice the impact of photon shot noise, which is often the dominant form of noise.

For me, there's something very special about a printed image or a photo/art book. I can't seem to fully appreciate the aesthetic qualities of a picture on a screen. It's the same with literature, e-books just aren't for me. But I guess we're all different.

dlb41: Has the X-A3 replaced the X-M series? The X-A3 has a plastic body while the X-M is all metal.

It's my understanding that the X-M1 didn't sell that well, sitting in an awkward position inbetween the X-A and X-E series. It seems that most of those who cared about better build quality and X-Trans also wanted an EVF, while the rest was tempted by the lower price of the X-A series.

In reply to:

FantasticMrFox: With Canon falling behind compared to Nikon in AF, in additional to the well established disadvantage in image quality, what reason (except for prior investment) do photographers have left to choose Canon over Nikon?

"If a certain tool affords you more keepers, you have more portfolio-worthy shots to choose from."

Of course, and there is absolutely no evidence that the difference in real-world performance is so large, that one of the brands consistently and for everyone produces more keepers than the other.

Prior investment is a pretty important reason, though. Also, ergonomics and handling are a matter of taste, and for many surely a reason to go with Canon.

And the much discussed disadvantage in IQ and AF, isn't really noticeable in the portfolios of skilled photographers. If it was, Canon shooters would be out of business.

In reply to:

Andrei L: You know what I don't get about DPReview's scoring bars ? The compare feature. If you compare the X-E2s to the X-T1, despite sharing the same sensor (and perhaps having some minimal sensor generation differences in the JPEG profiles), X-T1 comes out as better for High ISO and IQ overall. X-E2, same thing. I own X-E2, it's the same in every possible way, except for the protruding grip, back button labeling and the S having the actually quite welcome Auto (aka Hand it over to a noob to snap some).
While I do get it that the bar raises with each passing year, I'm wondering what value is there in the comparison feature, since it's so unreliable as long as 'expectations' change with almost every season?

There is a review site, can't remember which one at the moment, that re-calibrates the scale at regular intervals, lowering old scores as new cameras get increasingly better. That's an alternative to using an open-ended scale and grade "inflation".

Triplet Perar: This is what this sorry industry has become — a donkey piñata for the outdated Japanese business model of creating 'new products'.
Endless iterations of the same gear, with minor changes and different prices, twice a year, to create artificial offer until market suffocates to death. And they wonder why camera market sales are down?
We have cheeses with longer expiry dates than cameras.

So what money should companies use to cover R&D and other expenses, then, if not the revenue from sales?

Also, the declining camera market has nothing to do with the constant iteration of new products, because that's been the norm throughout the digital era. No, the sales decline has coincided almost exactly with the rise of the smartphone as the camera of choice for the masses. We are simply seeing a return to the sales volume we had before the digital era, when it was mostly enthusiasts who bought cameras. Just as the masses embraced digital cameras because of their convenience compared to film cameras, they are now abandoning those same cameras because of the even more convenient smartphones.

In reply to:

tommmee: Understand all comments about this unecessary upgrade but confused about the scoring. Does the older e2 really outperform the upgrade?

Exactly, there are no absolute scores, only scores relative to the current competition. The X-E2 was a more competitive camera back then, than the X-E2s is today.

When you think about it, it's difficult to give absolute scores, because at any given time you have no idea how a camera will compare to future cameras. The only solutions are to have an open-ended scale, or continuously re-calibrate the scale and lower old scores as new cameras get better and better. Or, like DPR, avoid the problem altogether by only comparing cameras to their contemporary peers, with the drawback that you really can't compare scores that were given several years apart.

In reply to:

The Squire: "we're leaving Nikon 1 cameras out of the list, as we believe the series is no longer being developed" - That's the big news in this review. When was this announced?

I think it's the lack of announcements that leads DPR to that conclusion. The J5 was released over a year ago, the S2 and V3 over two years ago, and the AW1 almost three years ago. Replacements for all models are overdue.

It seems like Nikon is placing their bets on the fixed-lens DL compacts instead (that is, if they ever get a release date). After that announcement, a lot of people wondered about the future of Nikon 1, but AFAIK Nikon hasn't addressed those concerns.

In reply to:

Najinsky: As you have raised the subject, I'd be interested in any further clues you can give as the the fate of the Nikon 1 series.

With the J5, the 1" sensor performance in now ready for prime time, competive with M43 sensors in cameras like th OMD series. But the J5 body is too much P&S and unbalanced with the tele zoom. On the other hand, the V3 body, with hot shoe, optional grip and finder is pretty close to the ideal compact body, transformable from seriously compact, to seriously great controls.

The lens line up is not complete, but there is a very compact and very good wide angle prime, an excellent portrait prime and an excellent tele zoom, which is enough to have serious fun with.

If Nikon 1 is dead, I'm going to start research for a crazy project to take the innards of the J5 and transplant them into the body of V3. I don't fool myself that this would be easy or possible so don't want to start to undertake such craziness until I'm sure all hope for a Nikon 1 V3 successor is dead.

With Panasonic's touch pad AF as implemented in some of their recent models, it's possible to select an AF point with your eye to the viewfinder. You don't need to see the screen, because you see the same thing in the EVF. It works surprisingly well.
