    an underdog has no other chance than to offer more than the top dogs.
    overall im not blinded by a good body.. i look at the overall system and what it has to offer.
    and pentax is no match to canikon when you look at the whole systems.

    pentax has no mirrorless system.
    sony can grab marketshare in a shrinking market because it offers the best mirrorless system today.
    sensors in pentax cameras are the sensors most other camera brands use too.
    so sensors are no reason to buy pentax.

    so the only way to look attractive is good cheap bodys with an impressiv feature list.

    but when you look at lenses, flash system, support, overall accessories for the system, then pentax does not look that good to enthusiasts.

    • gamer

      Pentax have great cameras but the lack of modern lenses is a major issue. Adding that most third-party companies do not produce lenses and accessories for Pentax (like Tokina, Tamron, Sigma, Yongnuo, Godox) it seems that Pentax is doomed.

      And I wonder why Pentax do not try to cooperate with some of the third-party lens producers. If they try to work together with Sigma/Tamron/Samyang it will be a move that will increase significantly Pentax sales.

      • Lars

        i guess pentax market share is too small to make it attractive for those companies.

        sure they do not have to design the whole lenses from scratch. lenses without AF like the samyangs are even simpler to adapt. they just need to adapt them to the pentax mount.

        but it is also a matter of how you distribute your production capacity.

      • Imp

        “I wonder why Pentax do not try to cooperate with some third-party lens producers”

        You mean just like their recently released D-FA 15-30 f/2.8 and D-FA 24-70 f/2.8 lenses? Both Tamrons?
        And before that, the 18-270 superzoom that is a tamron, and the 18-250.

        Also, the DA 12-24 design from Tokina? And the Da* 16-50, DA* 50-135, D-FA 100mm macro, DA 10-17 fisheye lenses that they traded to Tokina?

        Quite a bit of collaboration there 😀

        • gamer

          OK, you are right 🙂

          But Pentax 15-30 (which is rebranded Tamron) costs more than 40% than the Tamron version for Nikon and Canon. It’s a shame.

          On the other hand Sigma and Tamron do not make K-mount lenses anymore. Pentax definitely should do its best to bring these manufacturers back to game.

          And one more – Samyang have great full frame lenses but unfortunately they are manually focused. If Pentax ally with Samyang and give them the permission to produce autofocus lenses, then Pentax system would become very attractive.

          • Glorfindelrb

            I think you may have miss the main part of the announcement. Support of electronic aperture control for K70, Ks1, ks2, k3ii and k1. The mechanical coupling has been the main reason why producing k-mount lenses cost more to a 3rd party. Like Nikon did a year ago, Pentax is now supporting this and providing k-mount version of recent Sigma or Tamron lenses do no longuer require a complex redesing of the diaphragm.
            That’s also a new step to provide better video or to introduce a new mirorless mount with KAF4 adapter (not tomorrow but they had to do this first).

            And Pentax has already a very complete system for aps-c so this k-70 will find good and compact lenses. The FF system lacks some recent primes but it’s coming.

          • Little Dick Asian

            will not make a difference.. pentax is a doomed system.

          • ThePatriotMuckraker

            How is FONY not doomed and Pentax is? Explain tiny dick-head.

          • Imp

            Pentax may be trying to get Sigma back in the game by making their cameras compatible with electrically controlled apertures, instead of the mechanical linkage arm – the new 55-300. This should be easier for sigma to produce, maybe reduce their reluctance
            Samyang lenses are pretty great, that would be an interesting venture.

            EDIT: Glorfinderlb said it before me 😀

          • ThePatriotMuckraker

            He is right and you are wrong.

        • ThePatriotMuckraker

          Don’t you love when people are talking shit about a system without knowledge or facts to back up their assertions. The Pentax brand is coming back, big time.

          • Imp

            Don’t you love it when people respond to troll statements instead of discussing legitimate questions?

          • BP2012

            Yes Pentax brand is coming back. Ricoh consolidate them and they finally realized that their best chance is to make cheaper alternatives of high end professional still cameras. Like 645z and K-1. Because they have knowledge and technology and because they doesn’t have enough production capacities for mass production of entry level cameras. As example this camera has planned production for 30% less than full frame flagship K-1.

      “pentax has no mirrorless system”
      They have/had two, the K-01 and the Q. I’m not saying they’re amazing, but they at least exist.

      And who uses Sony sensors besides Sony, Pentax, Nikon? If there are other users, besides Medium Format manufacturers, please let me know because IDK. Canon makes their own, so does Panasonic and Fujifilm – olympus? I’d say sensors are definitely a reason to buy pentax – same as its a reason to buy Sony and Nikon.

      • Little Dick Asian

        lol…. k-01 and Q are no mirrorless systems.. they are stillborn systems…. bad jokes

        • ThePatriotMuckraker

          No, little dick fanboy, they are legitimate systems. nikon’s mirrorless are going NOWHERE, and FONY’s 4k oven “wonder boxes” are garbage. FONY lenses are a collared joke. FACTS. ALL facts, little dick. So sorry, Fony will be out of the camera business by the end of the decade and probably sooner, not Ricoh/ Pentax.

          • Imp

            Um… who is the fanboy here? I’m confused now…

      • Raghbir Jin

        No, actually, Panasonic manufactures many of Canon and Olympus’ camera bodies but Nikon, Pany and Oly get their sensors from Sony and Toshiba. At least, they did…until Sony bought out Toshiba’s sensor business. Samsung made their own sensors, and have made them for Pentax and Sony cameras in the past (among others), but you know….they gave up on the camera business. Fuji tweaks the array on Sony’s sensors, they don’t manufacture those X-Trans sensors themselves. Canon is the only other company manufacturing their own sensors now that Kodak is basically out of the picture and medium format switched from them and Dalsa — also to Sony.

        • Sakaphoto Graphics

          Panasonic has been making the sensor for the Olympus E-M1 since it was introduced.

          • Raghbir Jin

            Just looked into it, you’re totally right. I guess that’s changed in the years since I was selling cameras. I apologize for not double-checking my (apparently dated) information before posting.

          • Sakaphoto Graphics

            I suspect that many people have confused Panasonic’s dormant research period with their manufacturing operations.

            Supposedly, they’re still making quite a few sensors, but for their most visible products, such as the GH4, they use Sony sensors.

  • gamer

    I saw an article which claims that K-70 has on-sensor phase detection. If it is true, it will be interesting to see how fast and precise is live view and video in K-70 and how it compares with its Canon rivals.

  • TinusVerdino

    It has knob’s and stuff on it. Great call adorama guy
