Pentax K3 / K3II problems/issues

Surovi · 12-25-2015, 06:53 AM

Is there a topic where all the problems are listed?
Thanks!

Not that I remember, there were so few issues a 'problem' thread never really got started.

The only problem on k-3II was a lockup issue involving the GPS, but it affected only a small number of cameras and Ricoh issued a recall with the serial numbers. Even the affected serial numbers only rarely had an issue. It should not be a factor at this point.

I know it seems all new electronics have issues but the k-3 and k-3II have been remarkably trouble free.

Thanks!
Good to know

I`m in the middle of the Canon 6d - Nikon D7200 - Pentax K3II triangle

The Nikon or Pentax I could understand. .. not so much the Canon. ☺

Go K-3II

That there's no "Problems" thread suggests that there don't seem to be pervasive problems. I think that's noteworthy.

I can understand the Canon, great for filming, and amazing low light. But it has an AA filter.

Canon sensors are inferior in low light. The ones in Sony/Pentax FF are/will be better.

You can make a case for video, if that's your thing.

You're generalizing. Yes, Sony sensors are better than Canon in low light, but the 6d is better in lowlight than the D7200 or the K-3ii. It is a 20megapickle full frame sensor. The equivalent pickle density on a FF to the Pentax k-3 ii would be a 54 megapickle sensor. 16 on aps-c is the same as 36 on FF.

DXOmark, controversial, sure, says the 6d has good image quality up till ISO 2400, whereas the K-3 is good up till ISO 1250ish

Surovi · 12-25-2015, 05:09 PM

Sensors are behind the lenses. Canon has a great 70-200 f4 and good and affordable 24-105 f4. Sensor is good, better than Nikon and Pentax APS-C in in some cases, worse in the others.
That, and good ergonomics are the reasons why a 6d is in the game. AF is the biggest minus, and slightly soft 24-105/4 is another.
Nikon...perfect specifications, but is a little awkward in the hand...and no 50-135 (150) stabilized lens. Sigma 50-150/2.8 OS is tooooooo big.
Pentax, excellent ergonomics, even better than Canon. Lenses...khmmmm ... I'd like to have a 16-50/2.8 and 50-135 / 2.8 without fear of of sudden death

Sigma 50-150/2.8 HSM II is rare and not sealed. I do not like the idea that I have to buy a lens that would be my workhorse, without careful checking and at a venture.
I prefer the Pentax, but . . .

The biggest problems in this quest are me, myself and I

Ergonomics is one of the biggest factors for me

Surovi · 12-26-2015, 12:34 AM

For me too. The differences are not large enough to immediately verdicts.
I have a few more months for a decision, so ...

Though to be fair, the Pentax 645Z is better than all of the cameras you mention at low light.

To be fair to what? That's nowhere in Surovi's price point, i'm guessing. To be fair to a professional? A professional likely wouldn't be considering these cameras, if they need the capability of the 645z. The A7s is also better at lowlight than these three cameras. So what? Its not in consideration.
Apologies, but your point just seems a bit irrelevent.

I was just pointing out the incongruity of comparing the Canon 6D to the Nikon D7200 and K3II. A full frame DSLR will always have a one stop SNR advantage over APS-C.
