"Hence, professional photographers are switching to digital cameras"

No Way!

Good news: market up to 110 B$ in 2021 - bad news: dollar is only worth 25 cents in 2021 because of inflation. Doh!

Petroglyph: DPR thanks for posting this sample gallery. I was wondering about this lens for a walk around model since it has a closer MFD than the 55 f/1.8. Like most macros it seems to render a bit flat but could still be a very useful lens.

It might be an ugly lens at f/1.4 anyway. I shoot the 55 f/1.8 at f/2 all the time. At least it still looks very good there.

@Magnar W, At least it has a lower price (for Sony lenses). Might still be a fine walk around/ travel lens, but it needs, IMO:
At least one stop brighter for regular photography &
Longer work distance for macro type photo.
but very usable if compromises taken into consideration.
Enough contrast & color for everyday use? Everyone must decide for themselves.

KonstantinosK: The price difference between US and UK is eye watering. $1200 sounds reasonable to me, £1500 is too much.

@Contra Mundum, You forgot Trumponia, the new name for upstate New York. :^)

OlyPent: "51 MP." They added 1MP to one-up Canon which has the most to date. Tacky.

645Z already has 51MP. Copycats.

I forgot all about it. Very interesting cameras.

Nikon D750 = 1800$ => in round up. Pentax K1 = 1900$ => not in round up.

Nikon D750 would not use for pro landscape work.

Pentax K1 probably one of the best pro landscape cameras around.

?

D135ima: Blur and chroma. Pentax have not bad 60-250 for this kind of shooting. Although at 24mp he will be not so good like on K10 8 years ago

Pentax 60-250 f/4 = 1200$ and this lens = 400$. Notice anything different between the two? btw, 60-250 has no trouble with a 24MP sensor. This one doesn't seem to have that many issues either.

Nice Weather Sealed lens for the money. I hope Pentax make more lenses with the faster PLM motor installed. Thank you for the sample gallery, DPR.

Thank you for posting their interview. Ricoh seems to have more to say at CP+ these days. Looks like they are selling a lot more K1s than they expected. That means we should see some of the lenses from the road map next year and maybe a few upgraded limited lenses from the hints they dropped. The 1.3 K1 FW they announced has some new features in it. EFCS & 1:1 framing in the VF. It is possible many of the DA lenses would work well in FF at square frame.

TonyPM: Depending on the damage that people cause I think they should pay a penalty of at least 6 months of jail and a heavy fine. Atleast 15000usd sounds reasonable, but for those who commit really severe damage to a natural reserve of this importance should during their entire life.

Sierranvin: That comment reads a little media brainwashed.

Yes, double digital in fact. :^)

In reply to:

mosc: I would like the pentax lens line-up if my choices for a wider-than-35mm-equiv-AF-prime were the too slow 15mm f4.0 and the anchient and still not that fast (and certainly not sharp open) 14mm f2.8. Am I missing something?

Fuji's got at least 4 different choices:
16mm f1.4 WR (the one I keep drooling over)
14mm 2.8
18mm 2.0
12mm 2.8 zeis

Samyang have 8, 14, 16 for wides in K-mount. There is also Pentax 15-30 f/2.8 it is big and expensive but gets high marks from reviewers. Sigma has a 8-16.

Thank you for the gallery. Nice to see the 15mm in there. That one is a blue sky monster. The 16-85 is highly regarded but I don't remember any with it. Overall, it looks like a nice set of images to me, good work.

"Dheerankur filmed the piece on a Canon EOS 5D III with Pentax 50mm f/1.2, Tamron 90mm macro and Tair 11-133mm f/2.8 lenses."

Canon 5DIII with Pentax 50 f/1.2, not the combination one thinks of everyday.

stevenj2: Someone here picking and choosing numbers re usual US budget disinformation or ignorance. These figures are easy to find online. Not thru activist sites.

Military spending pct of total FY 2015 budget was $609.3 bil, 15.88 percent. Soc security, Unemployment & "Labor" $1.28 trillion, 33.26 percent.

US budget FY 2015 was $3.8 trillion.
MANDATORY spending, nearly untouchable is lots of entitlements. Social Security is 2/3 of that figure.

DISCRETIONARY spending was approx,. $1.11 trillion. Defense did account for just over half. Education is much smaller. BUT it is a State and Local role the Feds have increased their control of thru "strings" on funding, and pumping of dollars into the current college loan debt bubble.

Per National Center for Education Statistics,. United States,
"Total expenditures for public elementary and secondary schools in the United States amounted to $620 billion in 2012–13, or $12,296 per public school student ...."

56.2 billion 'Black Budget' is third. But it might not be hidden in discretionary and the actual amount probably depends how the category is defined. After all, it isn't called the 'above board' budget. :^)

Sorry too much alphabet talk. As Eric said, GES is Global Electronic Shutter and EFCS is Electronic First Curtain Shutter.

In reply to:

KerryBE: Is image stabilization a notable difference?

It depends on the lens and focal length. A non-stabilized lens in the 'normal range' the IBIS seems to be worth about 1-2 stops when viewing at 100% (A7RII). The camera is supposed to improve to 5-axis by working with an optically stabilized lens and I don't dispute this and haven't tested it. Compare to Pentax IBIS (their SRII) now seems to be pushing 4-5 stops with careful hand holding techniques. Caveat that this is not scientific but is a notable difference in both cases.
