On Medium well done: Two takes on the Pentax 645Z article (240 comments in total)

Well, i did not like any of the photos shown here. The main problem could be the leaf shutter, yes, but for the price, really dont think so, why would you expect that this camera would be better in any situation then the 30.000 plus dolars cameras systems?
This is a tool primarily for landscapers and still life, then the others, photography in its primitive very thoughtfull process of trying to get the perfect scene with the maximum amount of detail, DR, and less distortion. These critiques are for newcomers to photography, really, who knows about it would not make these kinds of mistakes. And im not even a good photographer.

mpgxsvcd: I will read the article when you add the other valid competitors for the LX100 to the article. Right now it just looks like an article to promote the LX100. And I am the biggest LX100 Fanboy out there. However, I still want to see a fair fight. Right now this article just looks like an advertisement for the LX100 and not a true comparison.

i'm sorry but you did not even read what he wrote...

RichRMA: You can't bend the laws of physics. Sensors can be made any which way, but the small ones will never, ever match the larger ones. Back illuminated, electron-multiplying, it doesn't matter. They are modest enhancements that produce a slightly better product, but a 1/2.3" sensor will never be a m4/3, APS, etc.

Many in the past said we would never fly, and here it is... closing or opening depends on your point of view.

Scales USA: Google also has facial recognition, so it can name the persons in a photo, and even inform the FBI if a wanted person is found.

The potential, as noted sounds both wonderful, and also frightening. Snapping a candid photo of a person and having them named? Its possible now for millions of people, but so far, Google is holding back due to potential privacy issues. (big $$$$$$$$$ lawsuits)

Thats what they want bigbrother full time, full population. Any data they want they have it. Control.

Never?
Thats arrogance, our "truth" is just a particle of what the truth really is, open your mind.

On Sony G Series XQD format v.2 memory cards introduced article (43 comments in total)

I can see it been used in professional bodys in few years. A99II probably will have it. For 4k or 8k use primarily. I can envision a new generation of sports cameras that will have 30 fps or more. The limitation would be file size basicaly 30 raw files per second is just too much, to make the camera cheaper they could use a smaller buffer and let the card be "the buffer". They make you pay more and you think about the cost of the card afterwards.

In reply to:

shutterbud: So, to test the new semi-pro sports camera which has been anticipated for yers, you go out on a sunny day and take portraits and landscape shots?
Pointless gallery, almost certainly designed to side-step the fact that the sensor is substandard compared to modern alternatives.
Can DPR please get their act together?

WOW, guys, if they are posting photos is so obvious that what matters is the sensor. when they post the entire review we will have an aproach about to the other things that makes a camera better than the other.
The image quality has an obvious importance and can't be downgraded for what it is, you buy an camera fundamentaly to take a good picture with quality.
I just don't think that sample pictures are representative, is like a "Petisco" to antecipate the main dish.

For sometime, i was waiting for a camera like this, the last time was the NEX7, diferent cameras, but i guess with right specs at the right time of launch.
I'm very very tempted to buy this camera. everything that i need for a family/travel everyday shooting.
Seems to be very good. The only point, utopic, i would like fuji like jpegs processing. But anyway, nothing that i can't do in post.

Nanospeed1: http://andrewvanbeek.com/fuji-x-lenses-and-full-frame/

As the guy below in the discussuion puts it, in DOF & bokeh area, FF advantage is very significant - I actually didn't expect that much difference in favor of FF...even canon at F2.0, expecting similar dof, it has much better bokeh , more blure, more pop, more 3D photo than Fuji at F1.4.... FF rules but sure it is not the holy grail for everyone. Those who want light weight and small equipment at the expense of the indisputable advantages in DOF, bokeh (also high-ISO quality and resolution) may prefer Fuji (and they got it right for sure) but for the most demanding phorographers, full frame is the choice. Actually, that was the reason Nikon finally turned to full frame long time ago too despite their early claims that "APS-C is the future for us"..... ;-).

Theres a obvious diference between cropped sensor and FF cropped. Heat generated, sensor readout speed, possibility of enhancements in fps and lower cost of fabrication for the manufactures. For us users the ovf diferences are notable because of the size magnification. By the way i like the idea of viewing out of the area of framing specialy for fast action photography. but not that much as crop in FF.

For the future i'm hoping for a new type of camera that has QXlike FF sensor, a customizeable body that you plug a detacheable evf that has a shutter button on it, and plug your cell phone to the back of the body.
You can use the cellphone touch screen to make the AF tracking like a joystick using the entire area or you could use the auto settings that track the eye when a person is recognized, the camera would write on the evf: -This is a person? you confirm and ask to track it. ;) yes, dreaming.

@EinsteinsGhost Yeah, that was the point i was trying to say.
I'm not going to invest in a7 as it is now. A9 will probably be the camera. For now we need a bigger, faster, and higher resolution EVF, a bigger grip with more confortable button access, a better af performance with af tracking.

Well, for manual focusing a7 series is probably perfect. But for af lenses i don't think so. A heavier weight body and with better ergonomics can balance well with longer and heavier lenses.
A7 series should be pro oriented but mirrorless.
Don't come and say that 35 1.4 or any other FF lens with AF is well balanced on the A7, it is not, its ugly and heavy front balanced.
A heavier body would not do that bad with shutter vibrations as A7r.

For this matter they would not need to do extremely sharp lenses and keep size down and weighting less.

If they want to pursuit small lenses, they should pursuit high iso 12/ 16/ 18 max mpx sensor, for compensating with a f/2, or f/2.8 lenses.

Sony should pusuit with A7 cameras the low megapixel low light performance and video performance in a box.
And sports Af if possible.
High megapixel count needs to be put in a very good tripod, and very good lenses to get the best of it. A7s is not a niche if priced right. I would switched to sony if A7s had better and faster Af, and the 4k video internal.
Next iteration please bring this, and make more faster primes.
The core of the system should be faster and small primes with aperture control.
