Re: Will Ricoh sell *Pentax* cameras after 2020?

[Alex Sarbu]

The "rumor" didn't made sense from the beginning: *we* don't know the
details about the Ricoh-Hoya deal, but Ricoh definitely does.
Yet we're supposed to believe that Ricoh - who is preparing for the
November anniversary - is either a. unaware they would lose the right
to Pentax brand or b. investing money into promoting the brand then
suddenly stop?

Re: PT: Ricoh G III

[Alex Sarbu]

The GR cameras were always Ricoh (this goes well before they bought
Pentax). That the GR III is a Ricoh branded camera is expected - just
like the DSLR products being branded Pentax (like the newly launched
DA* 11-18mm)

Don't worry, Ricoh isn't phasing out the Pentax brand - if anything,
they aren't phasing out the Ricoh brand ;)

The period ended last month; but check for an extension if you want to
do the upgrade.
Around here (Europe, the upgrade done by the Hamburg service) I was
told that I had to register for the upgrade until the end of
September, but the upgrade itself will be done later - and they're
still waiting for another batch of K1 II mainboards.

Re: Sounds like Pentax/Ricoh's resources are spread pretty thin...

[Alex Sarbu]

I see, thank you for the clarification.
However, I disagree with your interpretation; it can't possibly mean
that. We have paragraphs like:
"We have lots of requests for lenses, especially from K-1 users. They
want more lenses that match the higher resolution of the K-1, so
that’s one objective which we would like to implement.", or
"This form factor is iconic for the Theta. We think it’s important. On
the other hand, if there is demand, we would like flexibly to think
about any other possibilities, even for other form factors."
telling the complete opposite.

Actually I'm not sure what he meant... but let's not forget, he's a
Japanese speaking in a foreign language. Maybe they decided on the
upgrade because of the feedback? Maybe people are offering feedback on
the upgrade?
But it can't be not incorporating our feedback into new products...
the K-1 itself was made because we demanded it.

OTOH... people's demands are all over the place, often mutually
exclusive. Listening doesn't mean meeting all our requests.

Re: Hint on reviving old rechargable batteries

[Alex Sarbu]

Indeed, "intelligent" chargers would detect "bad" batteries and refuse
to charge them; and often you can jump-start them in a "dummy"
charger. Apparently that's a feature.
You could use the BC 900 to test or refresh the batteries (don't leave
the charger unsupervised! - nor near flammable materials). I assume
the old batteries had no signs of physical damage/leaks/corrosion.

Re: OT Cloud storage

[Alex Sarbu]

Hello,
I'm trying to choose a cloud storage myself. Crashplan sounds
interesting if you have large amount of data - though, how large is
"unlimited"?
Cloud is nothing more than "someone else's computer"; trust is very
important, as Bill pointed out.

How I'm planning to do it: I bought a NAS unit (a QNAP TS431p,
inexpensive but can do a lot) for main, redundant storage. With the
ongoing ransomware epidemics, I want to give my PC as little access as
possible to the data (which a DAS or external drives can't do).
That cheap NAS has tons of neat features, I still have a lot to
explore. For example, it's now getting snapshots - the ability to
revert your data to just before that ransomware encrypted it. It can
also detect silent data corruption using RAID scrubbing (only with
non-degraded RAID 5 and 6 arrays - and some would say ZFS is a better
solution), and being a NAS I can access it from anywhere (even from my
mobile). It has sync folders between multiple devices - with
versioning.

The NAS unit itself can take care of backups, on external drives and
on the cloud.
As for a cloud, I've made no choice yet, I was thinking about Amazon
Glacier as I wouldn't need fast data access - nor something like an
"unlimited" storage.

I cannot stress enough the threat of ransomware (or other forms of
data corruption). Backups are useless if corrupted data overwrites
good data - use backup with versioning.
And use at least 2 backups - main storage, even on a NAS with
redundancy, doesn't count as a backup.

Have fun,
Alex

Re: More news of trouble at Ricoh

[Alex Sarbu]

"When in panic or in doubt, run in circles, scream and shout" ;-)

Please ignore the alarmist Nikkei article - FTR Ricoh had to
officially deny 2 such "news", the one about closing down the camera
business (denied) and one about selling the leasing and semiconductor
businesses (not sure it means they won't sell those, or they didn't
decide if to sell or not).

Information can be found directly on Ricoh's site:
http://www.ricoh.com/IR/data/pre/pdf/h29q4_qa.pdf
http://www.ricoh.com/IR/pdf/presentation_text_2017.pdf

So, things are not rosy mostly due to their core copier business, and
they're reacting to prevent making a loss in FY2019. Ricoh Imaging
isn't doing that bad with the Theta and K-1.

Have fun,
Alex

Re: k-1 square crop test

[Alex Sarbu]

I've done some pseudo-investigation (actually, just opened a 1:1 RAW
in Silkypix and Pentax DCU).
They're saving the entire 3:2 frame, but with a tag for 1:1 cropping;
so you can recover the "extra" data - assuming your preferred image
processing software's crop tool supports this operation.
Silkypix does, and so does the Pentax DCU.

Of course, for JPEG there's nothing to recover.

Re: Some Pentax sales spotted, including 70-200/2.8

[Alex Sarbu]

The HD Pentax D FA* 70-200mmF2.8 ED DC AW doesn't use the same type of
SDM micromotors as the DA*-series lenses. Actually it doesn't use SDM
at all - but DC motors. Fast, reliable.

Last Pentax lens with these SDM micromotors was announced in 2008.
Since then we had 3 K-mount "SDM" lenses, all using Tamron's
"ultrasonic"-type motors (in case of the D FA 24-70 and 15-30,
ring-type "ultrasonic" motors).

Re: Extremely disappointed: K-1 does not appear to work with ...

[Alex Sarbu]

Is there any (real) advantage of old-style, mechanical cable releases
compared to the electronic ones?
Just curious.

 I think it must be humor of some sort.

 AFAIK, none of Pentax's DSLRs work with a mechanical release. I think
 the last Pentax film camera that accepted a mechanical release was the
 A3000.

Re: What grabbed me reading the specs

[Alex Sarbu]

Yes, you can use the Image Sync application to control the camera from
your smartphone or tablet. Transferring files is probably slow.
You can use wired tethering via the Image Transmitter application (I
don't think it's free though).

The sensor is moving inside a well calibrated plane, it doesn't tilt
at all. Yes, I know they wrote that.
The 5 axis refers to the axis of movement/shake the system can
compensate for, not the sensor's movement. So there's no sensor tilt.

Regards,
Alex

Re: My K-7 is dying

[Alex Sarbu]

Hello, Doug,

I'd say, skip the K-5 and get a K-5II - which indeed is a K-5 done
right, and with some tweaks added. If you liked the K-7, you would
like the K-5II even more.
I had a K-5, replaced it with a K-5IIs - it's worth the difference, IMO.

P.S. Both cameras have the excellent 16MP Sony sensor, much less
noisier than the K-7's Samsung.

Thanks, strangely the results so far are only mentioned in the RX1R
II's review - but if you go to the Cameras Scores list the 645Z is not
there.
As for the "sports" score, it's really just high ISO.

Re: DFA 150-450, first impression

[Alex Sarbu]

Thank you; I might replace the 60-250 with this lens so I'm quite
interested in user feedback.
Most of the sharpness was lost by using ISO3200, but I won't be
nitpicking about some quick, first samples. I'm looking forward to
hear more impressions about this lens.
