Pentax Full Frame

2016, April: The FF Pentax K-1:

TIPA prize winner 2016!

It has been a long time waiting for a Full Frame DSLR from Pentax. But during early spring 2015 it was finally announced, and from late April 2016 it is here. True to Pentax philosophy, this is for the advanced amateurs, not the most demanding pros. Not that it does not deliver images of high quality, because it does indeed, but price level is moderate, and the variety of extra gear is still not where the action shooting pros would like it to be. They may also demand more frames per second, as one thing.
Since 1969, though, when the 6x7 was introduced, Pentax has delivered cameras for the pros. Together with the 645, that was introduced in 1984, the 6x7 and 67 has been the tools of numerous professionals, especially in studios and on location. Bigger format deliver better images, therefore medium format has been Pentax' answer. So, for everyone except the extreme action shooters, Pentax is there. And the K-1 is narrowing the gap.
This is already recognized internationally, as the K-1 is a 2016 TIPA prize winner!
AND: Pentax K-1 is gaining much praise for its pixel shift system, among other things. Tests show that it outperforms most cameras, even those at far higher price ranges! (DPReview)

 

Pentax K-1.. Yes, it's here!
A new design. Programs and user modes to the left, as before. But look to the right! Two new dials for faster access to vital functions. Ten options on the dial in front, and a set wheel to the right. Which leaves less room for the information window. And the pop up flash is gone. (Like on the K-3 II.)
With this LCD panel on the back, the need for a big window on the top is gone. Note the 204800 ISO value. Not without noise, but it gives you a picture when it would otherwise be black.
The rear information screen can be tilted in any direction.
The K-3 to the left, K-1 to the right. Substantially bigger, but still a dream to hold! K-3: 784 grams. K-1: 982 grams. Both with battery and one card.
The difference in size.
Some changes to the information panel. AND: ISO values up to 204800 compared to the 51200 for the K-3.
Three of the many primes available for Pentax K- mount full frame: FA 20/2,8, D FA 100/2,8 Macro and FA* 300/4,5. Did you know that there are 215 lenses to choose from?

Let us look at the lenses suitable for the K-1, because there are quite a few:
Zoom lenses introduced 2015/2016 for FF: 
-D FA 15-30/2,8 ED SDM WR
-D FA 24-70/2,8 ED SDM WR
-D FA 28-105/3,5-5,6 ED DC WR
-D FA* 70-200/2,8 ED DC AW
-D FA 150-450/4,5-5,6 ED DC AW

These are high quality lenses and cover the range between 15 - 450 mm. So, nothing is really missing here.
What has been criticized while waiting for the camera, has been the ralatively few D FA primes available. And that is correct if one speaks of new lenses. But when including the FA lenses and the DA lenses that will work with FF, that critic looses some punch. First the D FA lenses:
-D FA 50/2,8 Macro
-D FA 100/2,8 Macro
-D FA 100/2,8 WR Macro
Then the FAs:
-FA 20/2,8, FA* 24/2, FA 28/2,8, FA Ltd 31/1,8, FA 35/2, FA Ltd 43/1,9, FA 50/1,4, FA Ltd 77/1,8,
 FA* 85/1,4, FA 100/2,8, FA 135/2,8, FA* 200/2,8, FA* 300/2,8, FA* 300/4,5, FA* 400/5,6, FA* 600/4, FA 600/5,6.

That makes at least 20 FF primes. I haven't even mentioned all. Are we lacking any primes?

All these lenses are superbe, with the * and Ltd series as leading stars. Some were produced from 1991 till 2004 for the Z and MZ cameras, some came later and are still produced. But will they do the job for a demanding FF camera? The Ltds will, according to tests. In fact, each of these 17 FA lenses scores very high (between 8,67 and 10,00 out of 10) on Pentax Forum user tests with digital cameras. The only feature missing here is the Weather Resistance. 
For that purpose, we have some DA prime lenses that are officially FF ready. Those are:
- DA* 200 2,8 and DA* 300 4, DA 560 5,6. 
 
So, there are at least 23 Pentax FF primes available. In addition, Pentax has a lens roadmap promising more primes to come from early 2017.

So, the list of superbe lenses is long. Probably longer than that of most other brands! According to Ricoh/Pentax, there are 215 K-mount lenses to choose from.. 
There is no reason to wait. Go out and shoot! 

I have also presented images taken with some popular DA zoom lenses, to show where they can work, and where not. Please see DA lenses on K-1
From looking at those test shots, I would recommend the following as a good mix if you do not have the D AF lenses:  
-DA 16-45/4, covering 20-45. Very sharp at 5,6!
-DA* 50-135/2,8, covering 70-200. Superbe quality from 5,6, even on heavy enlargements!
-DA* 200 or DA* 300, or FA* 300. (Or K 200/4 from 1975!!)

The official producer was Chinon, according to Alpa sources. But we know that Cosina produced some cameras (and lenses) for Chinon.

The ALPA 2000 was a Cosina with M42 mount. I used to own one. Ever wonder why there are ALPA badged M42 lenses on eBay? They are from Cosina too.

Sadly not found the Ricoh XR-7 / Sigma SA-1 / Sears KS-2 camera(s) on the site. They could be produced by Cosina as well, but I have no information about this.
