Jack Hogan: Where are the settings? No settings, no good.

@fina23: I really did, excellent symmetry.

Nice, great composition Mike.

@Bob: I hear you about the sugar-high processing.
@Savannah: I would if I were hoping to become as good.

On article 2016 Roundup: $1200-2000 ILCs part 2: Full-Frame (366 comments in total)

Is this supposed to be a 2016 survey or one for 2012? Using four year old list prices as a reference is disingenuous. For instance D750 and a7II bodies cost roughly the same today. Yet a reader of the 2016 roundup would be unaware the former, with its excellent complement of lenses, has been available for sale in this price range for some time.

Jorginho: From the Em5mkII review on HiRes mode:
"It's also worth noting that we had to re-shoot this test using the rather exotic ($1600) Panasonic 42.5mm F1.2 lens to get a consistently high resolution image out of the camera."

From the PenF: "The issue with this mode is it reduces the effective pixel pitch by a half, makes each pixel effectively 1/4 of its former area. This stresses the more affordable Olympus 45mm F1.8, our standard Micro Four-Thirds studio scene lens, so for this mode we switched to the top of the line Panasonic-Leica 42.5mm F1.2 Nocticron."

So why did you not use that very same lens now, but went precisely for the lens you already know cannot keep up with such a resolution? At least to keep it consistent and comparable. Not that the 45 m f1.8 sampels are useless..most people won't have a 1250 nocticron. But we want to know what the cam can do, not restricted by a (for this purpouse) lacking lens.
May be an article on HiRes with many mFT lenses would be informative.

They did not use the high-end lens because that rationalization does not hold water: if a lens works well for 1 shot at 20MP, it will work just as well for 8 :-)

Sucks. I don't own an MBP precisely because I don't like being locked into an expensive walled garden, having to cart around all sorts of non standard cables and dongles to boot.

What are PP constraints? The bear image is eerie, dramatic and beautiful at the same time but imho diminished by the HDR processing.

The crow is beautifully done, and so very London.

Great idea and composition on the orangutan. Can't say I am too impressed with the sharpening artifacts, especially in the distant foliage.

Vic Chapman: Congratulations on your win with this beautiful picture. May I ask where it is and if you know the name of the flowers that grow so well at this altitude and temperature.
Regards, Vic

Don't know where they are but those look like rhododendrons. Jack

It's tough to keep all the balls in the air at the same time. Great job guys, fantastic improvement over the previous studio scene.

Seems a bit Canon heavy for an unbiased list...

In reply to:

Jack Hogan: Well done. I feel however that to fairly compare noise and DR in captures taken in pixel-shift mode with others, one should first stack four captures of the others.

Are you mixing up SNR with spatial resolution? It's amazing how many people do. SNR/DR is measured in a uniform area like the one shown in the comparison above: the K-1 has no advantage there if compared apples to apples (i.e. 4 captures vs 4 captures).

As far as spatial resolution is concerned, pixel-shift provides an advantage in chromatic areas - but very little or none in neutral/hueless ones: http://www.dpreview.com/forums/post/57727279

Kudos to Pentax, but let's not stretch it beyond what it is.

Cheers,
Jack

Andrew Elliott: If only my Q had a CCD sensor...

Colors out of CCD sensors are no more or less juicy than out of current sensors: it's just that since the days of CCDs a decade ago manufacturers have figured out that if you keep your customers on a constant sugar high their photographs all start to look like Ken Rockwell's.
