On Interview: Canon's Chuck Westfall on the new XC10 article (352 comments in total)
In reply to:

FiveForm: On the face of it, it would appear that Canon had at least some aspects of the Sony RX10 in mind when building this camera - fixed lens, video/still hybrid design, high initial price tag...

But even Sony's "High Initial Price Tag" is half of Canon's. And with a significantly faster constant aperture lens.

I keep wondering when Sony is going to release the RX10.4K. Given it's the same sensor as the AX100, you know they can anytime they choose to.

gskolenda: This XC10 is a complete planned rip-off or Canon is just stupid!

I will take the Samsung NX1 and there 16-50 lens over this XC10 All Day Long!
Even though the NX1+Lens package cost $400 more!

The NX1 still ends up being cheaper. Those Cfast 2.0 cards are crazy expensive. Buy three 128 GB CFast cards and you've spent as much on them as the camera. And the file sizes on the NX1 are far less so they require less storage for shooting, editing, and backup.

Actually, I went to Adobe's website and a couple of hours after I wrote my above previous comment found where to buy the standalone product.

It is now installed on my desktop & laptop.

I am assuming from Lightroom 5 to Lightroom 6. So far Lightroom 6 appears to be available ONLY as part of CreativeCloud. Unlike Lightroom 5, 6 appears to have no standalone version on Adobes website.

As a Panasonic GH4 owner I am less interested in higher pixel count and more interested in improved low light sensitivity and dynamic range combined with lower noise.

Aur: "The other thing is heat. Because the sensor is always on, it generates heat. So with current technology we believe the time is not right for us to make a large sensor mirrorless camera. "

I wonder what this means for the longevity of a full frame mirrorless. They hint they ran into heat problems obviously, I know a Sony mirrorless can actually physically shut down in a hot climate when you've been shooting for a long time, especially with video, and Nikon has some patents to try to cool down the sensor. The camera will simply shut down to try to protect the sensor from the heat.

It isn't so much the longevity of the sensor that is at issue but the fact that image sensor noise increases with temperature. The temperature at which the image sensor can return a high quality result is a lot less than the temperature that will cause damage.

wildkat2: Good interview from a tough subject. And good on you for asking pointy questions about the AF speed. Pentax needs to hear that we expect more. Pentax is not quite as secretive as Apple used to be but they come from the same school of thought.

I disagree with you about the "bulkiness" of the K-01. Paired with the DA40XS it is a joy for traveling and only slightly bigger than your typical super zoom. I think its unfortunate that most people looked at the yellow version, said ugh and decided it was "bulky." I wish Pentax would make a "K-02" that fixes things like lack of WR, slow processor, etc. Now about that 15-450…….

I also have a K-01. A substantially reduced flange-back distance would not actually reduce the size of the camera that much. The need for a decently sized grip and battery is in fact the limiting factor. When I put my Pentax K-01 and Panasonic GH4 next to each other, it is the GH4 that is the larger.

Leandros S: I feel the landing page summary glosses over the fact that for Vaio, being spun out looks like the beginning of the end as product support and sales were abandoned for all markets except Japan.

I would be sure that Sony, like IBM before them, is finding the margins of the PC business to thin to be worth their time.

noiseky: I mean, what particular camera was used for each winning entry? Hope the photographers can also share the settings. Secret perhaps in producing these kinds of captures?

Download picture, open, look at picture properties, all is revealed.

In reply to:

AbrasiveReducer: I love Ricoh's better stuff and certainly nothing wrong with Takumar lenses. But what is the compelling reason people would pay these prices, plus buy a new body to go with their new lenses, and sell their Nikon/Canon/Sony at a loss? Unless its someone who can afford FF but won't buy one unless it's a Pentax, I guess.

Someone who has already invested in the Pentax system and is upgrading from a crop sensor body to FF. The FF camera is backward compatible with the DA lenses AND handles FF lenses properly as well. So they are not selling their Nikon/Canon/Sony cameras or lenses period, much less at a loss.

mediasorcerer: that nx1 is HUGE for a mirrorless, when samsung gets the quality of ther lenses up to fuji/ oly/sony zeiss standards then it may help there sales, but the nx1 was a poorly thought out mirrorless camera as its way too big/ its a dinosaur and way too expensive, the lenses are huge too, defeats the purpose of milc.

no firmware can change these facts/nor marketing spin, thats why its a flop of a camera.

for the money, your way better off with ff canikony or equiv.

Yeah, you'll appreciate that small mirrorless camera size which provides a poor grip whenever you hang some heavy glass on the front of the camera....NOT.

The point of a mirrorless camera may be small camera size. It may be that it makes it easier to make a camera that does either still images or video equally well. And the two do not have to always happen at the same time.

LukeDuciel: I am looking (eagerly) forward to A7s mark II.

I would expect 12 - 18 months between release of the original A7S and the Mark II. That's just the way product development and release typically go. But we can hope.

In reply to:

select: when they will make a 50mm and 35mm f1.8 at the same price point of Nikon and Canon? (so it means around $250)
this system won't be successful if they don't make some good quality but cheap lens

Fast, good, and cheap - pick any two. And it applies in almost any business.

nicolaiecostel: Everyone's announcing cameras and Ricoh is announcing announcements. What have they been smoking?

@LensBeginner
The Pentax 645Z is a great camera by all accounts, and very inexpensive by the standards of the other machines in Medium Format, but even so the volumes it will sell in are microscopic. It is a niche of a niche.

You nailed it. CES comes with Pentax having no new product to show says it all.

qwertyasdf: Hey, I heard that Pentax will finally release a FF DSLR next year.....for the 10 past years.

I will believe Pentax is doing a FF DSLR when I see it and it's available for purchase and not a moment before.
