Third Party Manufacturers / Re: Nikon D750 to be Canon 5D3 competitor?

Ahhh, yes...anecdotes.  % of what?  20?  200?  20,000?  Ot that last number is likely to have any significance or impact on Canon's priorities.

A higher percentage then the sample size for the Nielson ratings for example.
But your still on the "mixing market segments as if all cameras had the same target demography"-trip

Or could it be that the 'issue' is neither as widespread nor as impactful as you're implying.

If it isn't a iusse, then why did the share of C-users in our extended professional network drop from ~90 to ~30 percent?

Sure, that observation doesn't mesh well with certain confirmation biases...

so I wondered if any of you know how to calculate the changes in min/max focus based on an extension tube of size "x" with a lens of length "y".

distance of subject to sensor = (focal length + width of the ring)*(1+(object size/image size on the sensor))
Keep in mind that in most modern lenses the actual focus length changes due to internal/rear focusing; you can use the formula w/o ring and the actual distance and magnification to get the real focal length at minimum distance

  What happens when Sony buys controlling interest in Nikon's publicly traded stock?

Exactly nothing, as Mitsubishi won't sell and thus jeopardize their investment in the core technologies Nikon brings to the group.

The argument is in how far this 'older tech' really effects the final image, given all the processing options that are available.

Even with the processing available: it takes time, and time is money(or at least not spent with something more delectable). Thats if the NR artefacts areaccaptable.

Business of Photography/Videography / Re: 4K, 5K, 6K and Up Video

I'd suspect that editing a 4K video that is full quality with no lossy compression will require some rather exotic editing hardware.

It's only 4 times the data of fullHD.
Compared to even consumer level CG compositing that isn't half as demanding as it sounds - CG rendering is done in layers, to get a "normal" looking stream you have to blend on average a dozend layers - each a full resolution stream on its own - together. That worked fine 10 years ago.

(Working with proxies can be an option as well.)

I'm not calling MILCs the paradigm shift. The paradigm shift is the significant gains being made in sensor IQ.

Maybe closer to a paradigm split.
Lets keep in mind that there are two groups of buyers - kit only vs. more serious.
For the first group MILCs can be made cheaper, allowing for profit even without selling additional lenses.
The second otoh values quality and is willing to pay for it. Those buy high margin items.
Mixing those groups together would be misleading, one could infere that sales to the first group are a good indicator for the second population being stable.

Good autofocus would not hurt image quality or performance.

Autofocus tends to go with short adjustement paths, often only a 45° turn on the focus ring for example. For manual focus , esp with a fast lens, you want the opposite to increase precision. The second lens would have a glacially slow AF, the first a focus-by-wire like the EF85/1,2.
Not that AF works that reliably when you mix shallow DOF and threedimensional subjects - playing with the focus confirmation for MF can be enlighting in that regard. If I were Zeiss I wouldn't want to have to deal with countless people confusing the limits of lens and body...

If that on sensor PDAF works and tracks well, hooboy...

Key factors would be processing power(shouldn't be a problem), being able to read the sensor fast enough to avoid choppy data and worse excessive subject motion during the readout (lets see; but it sound promising), leaves us with the software, thats a wildcard.

And another person that couldn't photograph the inside of a paper bag

Well, guess I prefer sujets & subjects that actually make the cut for paid for publication.
Should the paper bag ever be a topic I'll defer to your expertise.

I think if you honestly believe there isn't a trend towards better IQ, your not looking and observing what's going on around you. I'm not saying Canon camera have disappeared from the streets. However, I HAVE seen a greater diversity of cameras than I used to...several years ago, it was pretty much Canon. Pretty much every landscape photographer I knew or encountered had a 5D II. Today, most of them have the D800, some the D600 or the A7/r. Those are trends...they are observable in real life. It isn't a purely Canon-dominated world out there where they have over 48% of the market...things are diversifying, and while not everyone is going to Nikon, they aren't always choosing Canon anymore.

Same idea for fashion/glamour & advertisment - those used to be 5D2-dominated, something in the 80% range. Well, today 2/3rds are not Canon. And if you talk to the people you hear that status quo this trend will continue as tax depreciation allows.
Now this doesn't show up in the sales figures as the gear has already been bought. But it would be wise to consider the implications for the next cycle.

You should seek professional help, something might be blocking reality of lens limitations from sinking into your brain.

And another person who doesn't understand that lenses are analog devices. But lots of blind faith in numbers to compensate...Penn&Teller come to mind :P

It's that simple.

Only to those who don't understand how the resolution tests work. Those misconceptions lead to fallacious assumptions about which lenses are suitable for higher res sensors and which are not.
Really now? Lets take your advise to the extreme and slap a nikkor 50mm from the 1970's on a 5D3 and a D800. I bet the resolution difference will be indistinguishable or at best negligible. Afterall, it should be able to resolve so much detail on the Higher MP body.  ::) ::) ::)

You should really work on your comprehension skills. Both here and a page earlier.

...but I would actually really love an 85mm f/1.4 Otus...that focal length is just so sweet on FF.
Pair it with a 35mm and I have a nice recreational set.
Guess the 35Art will fill in for a while.

mocks the trolls and demonstrates that the best response to trolls is humor.

Selfmocking trolls? Well, that kind of recursion is topically invariant.
