Pentax K-01 Mirrorless K-mount Camera

Initial specs leaked · 01-19-2012 · By PF Staff in Pentax Rumors
Pentax K-01 Mirrorless K-mount Camera

Pentax is slated to announce a new k-mount mirrorless body at the CP+ camera & photo show in Japan, according to the latest rumors leaked by a Japanese camera blog and other sources.  CP+ runs from February 9th, 2012 through February 12th; it starts in just three weeks!

The K-01 will be a mirrorless camera that uses the current K-mount lenses compatible with the Pentax DSLR lineup.  Judging be previous rumor trends, we believe this name is tentative.

Further specifications

  • "921,000 dot" 3-inch, VGA LCD screen from the K-5
  • K-5 image processing and sensor (16.3 Mp)
  • 1080p HD video at 30fps
  • 1/4000s-30s shutter speed range
  • Contrast-detect autofocus (81 metering points)
  • Built-in flash
  • 12.1cm wide x 7.9cm high x 5.9 cm deep (compare to Pentax Q at 9.8cm x 5.8cm x 3.1 cm)
  • 560g loaded with battery (compare to 200 for the Q)
  • New DA 40mm kit lens
  • Available in 3 lens kits
  • 3 different colors
  • Electronic viewfinder

The most exciting thing about this camera will without a doubt be the fact that it uses K-mount lenses, making it compatible with thousands of current and legacy lenses both by Pentax and other manufactures.

Judging by its size, this camera will be closer to a DSLR than a compact camera.  As it's rumored to be developed by Hoya, this means that it's been in the pipeline for a while and it will likely have a lot of components in common with the K-5.  It is also believed that alongside this camera, replacements for the current DSLRs (the K-r and K-5) from the pre-Ricoh era are being finalized.

Read more in the K-01 rumors thread on the forum.

We would like to close by mentioning that while no rumors of a full-frame Pentax DSLR have surfaced, if the Pentax full-frame facebook page receives 3000 likes by CP+, it will be brought to the attention of Pentax executives and at the CP+ show.

So It's a K-5 but completely silent...hmmm ,,A new Company just bought Pentax and everyone expects them to out do the other Companys from the get go, come on guys Japan still isnt at full speed and Tailand Is still under water. So all you that can't wait make sure you add your gear to the Pentax Marketplace for us that still love our Pentax and could care less about FF. My K1000 still takes great pictures.

Davor [Delete] Jan 28th, 2012 7:22AM

Actualy, Pentax has many FF bodies but only analog. Maybe they can do cheap digital back for it :-)

LightSpeed [Delete] Jan 27th, 2012 8:38AM

I'm about to abandon Pentax once and for all. Here is why. They come up with this mirrorless crap, instead of a full frame. They take away the big bright beautiful 100% Pentaprism, and add a crappy electronic viewfinder. Which is what I had with the Sony, that I hated. I love the K5 and always will, but I want a full frame and Pentax is not moving fast enough. nor are they catering to what serious photographers want. Looks like Nikon D4 is in the cards for me.

gybp [Delete] Jan 27th, 2012 1:46AM

so why not buy the k5 and forget this camera? i hope that they fix the video recording on this camera...or better yet, that they make a K6 with all i need, higher flash speed sync, manual control over video, better video codec...

timh [Delete] Jan 26th, 2012 1:34PM

A mirrorless camera that's no smaller than their current SLRs? Seems like it's missing the point entirely. I'll wait and see but I'm far from optimistic based on recent weird decisions and products.

D0n [Delete] Jan 25th, 2012 3:12PM

the standard k-mount is big enough that a lens designed for aps-c mirrorless could sit recessed into the body of this new evil cam, while maintaining older lens compatibility.. any body really think Pentax can't make a tiny lens?

pistik100d [Delete] Jan 24th, 2012 8:41AM

Pentax did already small body for film. This is not a miracle. I love the user friendliness of Pentax like the highest compatibility with the last 50 years. The silly adapters are not used at all. We need the real and original K mount. I just a bit worrying about the new viewfinder. I like the viewfinder of Fuji Xpro1.
Anyway "K" forever!

wed7 [Delete] Jan 23rd, 2012 10:47PM

wow! i would really like to see MILC in k-mount from pentax, looks like this 2nd body aside from the Q is really coming, ^^, but wait, where are the lenses?

qwerty [Delete] Jan 23rd, 2012 2:02AM

I would take Adams word for when he says "This isn't the K-r replacement, it's a new mirrorless".

curiouspeter [Delete] Jan 22nd, 2012 4:46PM

If this is a K-r replacement, let's hope that it comes with a metal body. I really appreciate the feel of my K-7. It is just a bit big.

Ubuntu_user [Delete] Jan 22nd, 2012 11:26AM

m8o, my question exactly. And of course, battery life is not nearly as good, and out in the bright sun I wouldn't even be able to see what I was shooting...

Yeah, however, it seems that the market is heading into mirrorless for the APSC sector. For size? For features? I'm not exactly sure. I do think it's fantastic that Pentax is jumping in and being a contender.

m8o [Delete] Jan 21st, 2012 8:49PM

Can I pose a perhaps stupid question? If I have 'LV' button on my D-SLR, why would I want a Mirrorless K-Mount body camera presumably similar in form factor to the K-5?

Davor [Delete] Jan 21st, 2012 11:22AM

@netrex: did not know that. K20d was my first dslr ever. Ok, ok, i will go to 645D because bigger body :-)))

netrex [Delete] Jan 21st, 2012 9:36AM

@Davor: I think you're in the wrong brand then, the K10D/K20D were unusual for Pentax as they were bigger than Pentax normally is :)

Davor [Delete] Jan 21st, 2012 4:38AM

I do not like body smaller than K-5 has. K-20 was the ideal size camera for me. Want lower weight camera but not lower size. Will see what will Pentax do about that :-)

knakni [Delete] Jan 21st, 2012 12:07AM

I looked at the blog in Japanese again. Perhaps a more literal translation would be "Although it is not an OVF, it is not clear whether there is an EVF or not, or whether it is built-in or external".

knakni [Delete] Jan 20th, 2012 11:13PM

The referenced Japanese blog does not actually confirm EVF. The Google translation "In optical viewfinder, but the presence of EVF, is not clear about internal or external" is not correct. It rather says "There is no OVF, but it is not clear whether there is an EVF, or it is built-in or external". My interpretation is "There is no OVF, and it is not clear whether there is an EVF. If there is any viewfinder, it is not clear whether it is built-in or external". I sure hope there is a built-in EVF like the one on Sony SLT A-65.

bigjonnee [Delete] Jan 20th, 2012 4:51PM

I realize this thing has top of the line specs, but I was dreaming of a mirror-less K-mount smaller than the K-r/K-x.

s.randy [Delete] Jan 20th, 2012 3:12PM

Ahhh I can wait to see this thing!!

Adam [Delete] Jan 20th, 2012 2:34PM

This isn't the K-r replacement, it's a new mirrorless.

mathan [Delete] Jan 20th, 2012 1:45PM

Maybe Ricoh doing it like the Leica M mount in their GXR in this case K mount for the K 01 whatever.

ScreamingIdiot [Delete] Jan 20th, 2012 1:31PM

So is this the K-r replacement, or a K-5 Super type?

Ubuntu_user [Delete] Jan 20th, 2012 12:53PM

I see this as being a really good thing...

1. the market is moving toward mirrorless, and Pentax is going to be a player
2. it's not compromising on size (Pentax already has the smallest out there: the Q), but instead will most likely be a performer that will give all the other brands a run for their money.

pcarfan [Delete] Jan 20th, 2012 12:14PM

The market without a question is moving towards mirrorless. That part is pretty much a no brainer. Pentax also has many small lenses in K-mount currently available for sale (DA15, DA21, DA40, DA70 and even the DA-L 35/2.4) and thus it makes sense to release such a camera. Every system is a comromise, and I think this compromise of being larger than other mirrorless but smaller than DSLR's and backwards compatible with a lens system known for its smaller primes has a place.

Edgar_in_Indy [Delete] Jan 20th, 2012 9:48AM

Ummm...I don't think that's supposed to be a real picture of the camera.

richard balonglong [Delete] Jan 20th, 2012 7:07AM

Hmmm... If I'm seeing it right, it has two mode dials... The photo of this rumoured camera maybe two different new Pentax body, or one new body with two mode dials...

kadajawi [Delete] Jan 20th, 2012 7:03AM

Maybe it will be cheaper and lighter? You can save space on top when there is no prism... although it might look a little odd.

This might be tempting, although after just having seen the Fujifilm X-Pro1 which is simply stunning and full of want... oh well. But if the price is right...?

Perhaps this thing could have a very high quality OLED viewfinder? Or use the space that is wasted due to the necessary flange distance to integrate an aperture control ring for use with lenses that do not have one?

kff [Delete] Jan 20th, 2012 3:57AM

where is wi-fi for remote controll and lifevief ... ?

I want to buy a new GXR body with its and K-mount module for it ...

Tord [Delete] Jan 20th, 2012 2:46AM

One possible technical solution is to have a K-Mount-to-K-Mount adapter on the camera - without the adpater you can use the new compact lenses, with it you can use all the old - not the most elegant solution, but doable! We will know in a few weeks time ;-)!

Chex [Delete] Jan 20th, 2012 1:59AM

So they removed the mirror from the K-5 and gave the video 5 more FPS... this things burst better be 10-11 FPS continuous for at least 40-60 shots before the buffer is filled and the time lapse count be 4 digits instead of 3.. Now why wouldn't they simply have announced at CES or have this leaked at CES to start generating interest instead of 1 1/2 months before the next event..

Edgar_in_Indy [Delete] Jan 19th, 2012 11:28PM

It's probably good that they aren't competing to have the slimmest mirrorless camera. Who wants to dangle a 70-200mm lens off a camera that's as thick as a deck of cards?

Adam [Delete] Jan 19th, 2012 11:19PM

This camera is about as big as the K-r (which is good)- so no reduction of size, for once. It looks like Pentax will be focusing on performance instead.

This also suggests that the same K-mount lenses can be used as on DSLRs. What would be the point otherwise?

Ubuntu_user [Delete] Jan 19th, 2012 9:59PM

Go Pentax!!!

KFrog [Delete] Jan 19th, 2012 9:33PM

Finally! Signs of life from Pentax. Nice to know something is happening over there.

bozianul [Delete] Jan 19th, 2012 8:17PM

So: the K mount, the same sensor. I doubt it could use the same lenses. That would mean the optical-physical formula/design is the same as (D)SRL... Why mirrorless if the flange distance will be the same? Where is the reduction of size? and so on...

Iarebokeh [Delete] Jan 19th, 2012 6:53PM

Please, please, make it weather resistant.

WillWeaverRVA [Delete] Jan 19th, 2012 6:38PM

7.9cm, not 79cm. The article this was sourced from says 79 *mm*, which is 7.9cm.

gaeriel [Delete] Jan 19th, 2012 6:00PM

79cm? that's a bit high, isn't it?
