It seems to me - yes...I've read about it...But they are the first birds to return...It's strange to see robin in January, although it's Sankt Peterburgh, it's European part of Russia....

Not only Pentax has crop mode in FF camera....:)

Pay attention, that FF market will be crowded with L-Mount Alliance Leica, Panasonic and SIGMA soon...
Leica has three new mounts, by the way. TL, SL and S.

It's Europe. 20 kilometers (12 mi) east from the Estonian border. :)

Not Siberia. :)

Pskov is one of the oldest cities in Russia
Pskov - Wikipedia

The temperature was 28,4 F :) But dank weather...

Ricoh is in deep stagnation and it's fact. The reference to small-size of company is farfetchedness. Ricoh Corporation is not small, if the owners of company had wish to expand the photo division, Ricoh could be not less successful than Fuji did. They keep Ricoh imaging company alive, but without any progress.

The share of Ricoh (Pentax) on Japanese DSLR market is the smallest (3.1%) for all photo history now.

OK...They will launch new GRIII this year, maybe new 1-2 APS-C camera(s) and 1-2 new lens(es)...
How long will they be afloat with so slow and conservative life? Hard to say....

Even Leica goes beyond their tradition products...

The real focal length of 200 mm zoom could be 201-210 mm.

Pentax really needs several FF DFA f4 zooms and several f1.8 (2.0) DFA primes to offer till 2021-2022.

To say honest, this lenses are not really good at K-1. DA *55, DA 50 f1.8 and DA 40 are APS-C lenses. Not bad at f5.6-8 - yes.

There are some APS-C zoom lenses usable at K-1, but IQ is from mediocre till not bad.

DA560....It seems to me Pentax users better choose DFA*400/5.6 with 1 kg weight, only 200 mm length and 77 mm filter for much lower price instead of 3 kg and 520 mm length and 112 mm filter for USD5000...

Remember film time line of lenses?
Pentax K-Mount Lenses and Lens Accessories | The K-Mount Page

FA20/2.8, FA*24/2, FA28/2.8, FA28/2.8 soft, FA31/1.8, FA35/2
FA43/1.9, A50/1.2, FA50/1.7, FA50/1.4, FA50/2.8 macro, FA77/1.8, FA*85/1.4, FA85/2.8 soft,
FA100/2.8 macro, FA100/3.5 macro, A*135/1.8, FA135/2.8, FA*200/2.8, FA*200/4 macro, FA*300/2.8, FA*300/4.5, FA*400/5.6, FA*600/4

and...a lot of zooms...

I think that Pentax users of K-1 want the line of lenses close to old one and ASAP...

I'm not sure that we will see such line of lenses in the nearest years...

Of course...

But to make film photo of black and white lines and make the same with digital sensors are not the same.
Sorry, I don't know English very well to discuss this theme.

Modulation Transfer Function is for film testing, new digital time just uses old term. The modern testing like IMATEST and old MTF testing are different methods, because of different light receiver. You had read the article and understand nothing?:)

A practical way of understanding line-pairs is to think of them as pixels on a camera sensor, where a single line-pair corresponds to two pixels (Figure 2). Two camera sensor pixels are needed for each line-pair of resolution: one pixel is dedicated to the red line and the other to the blank space between pixels. Using the aforementioned metaphor, image resolution of the camera can now be specified as equal to twice its pixel size.

It's just rough try of comparison and explanation for modern people. it's metaphor

NO pair of lines in sensors.
