On Canon EOS 7D Mark II: Real-world samples (beta) article (269 comments in total)
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.

What are you talking about?
This is lens lack of resolution at the borders.
Are you expecting what?

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.

Oh god, theres a gap between a7 and a77 size. if sony don't do it quickly someone will. Please small lenses sony this system is faded to fail in its purpose.

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.

Ok, Fuji is the only one that found its correct niche in my opnion. Smaller, lighter, apsc sized with new sensor tech. smaller and lighter lenses as fast with very high quality, construction and performance.
now nikon is going Full Frame. And for what i see, the 36mpx sensor is the limit for the actual lenses. Otus? 10% or less will buy it. As mpx goes up the border resolution diference from the center resolution, of affordable lenses, will rise, and its ugly. 24-25mpx is just enough for the lenses we have now. Lenses are dificult to produce no one wants to wait more 10 years to develop lenses at affordable price to put in our 54 or maybe 100mpx sensor.
We want lighter lenses and bodys with the same or higher quality then our FFs now. Very light FF bodys don't balance well with not so light lenses. the proportion is already achieved in FF, now they need to maintain proportion and reduce size. Sony is not doint ic correctly and 4/3 is too small.

Marcelobtp: When i have time to think about it, is the best and most rewardable time in photography for me, when i understand how we react to diferent shapes in diferent positions, colors, bright and dark..., i get very conciuous about what i'm doing.
If it will stuck in my head and i will do it as natural as peeing, i don't know. I think there are too many people that don't want to or never thought about these analitical points when taking a photo. Well, photography as any other thing in the world is science, i guess everything is explainable, you just need to elevate your consciousness. I love this "behind the shot" articles and hope to one day teach people to think before taking a picture, in the same or better way than this.

yep, i agree with you, i guess im not very talented guy and want to prove to the world that is possible to became a great photographer or artist gaining counciousness of it. The union of the left and the right side of the brain, that im defining as the analitical and instinctive , should provide the better results, as you say there s not 100% to any of the sides. And people do and search for what side may dominate their brains

But, i think it is sort of uniform dogma, as music as any other art, but how you are going to organize this to yourself is diferent. The globalization seems to more and more creating a kind of universal language. The photography has a message to pass, maybe you have a secret message that has only meaning to you but overall we are trying to create a message that people understand or at least find interesting, intriguing.
Everyone sees diferent, poets pass their message in their way, but generaly the messages are understandable because of the language, even though they are still unique. "Ukai mazuki minai" maybe it sound beautiful... but the message is not understandable, because you don't know the language. Theres a languange and a science, but how it will get dismistified, or even if it will, and what it will cause, again, i don't know. But this is what motivates me about photography. The inteligent concious process of it.

We need to see Af performance with very shallow depth of field, and long teles. For now image quality seems to be on par with the others.
