  • Well, all new Pentax cameras have backwards compatibility with older K-mount lenses (and even older non-bayonet). The new K3iii even more than my KP and K1ii. But it is truth the newest lenses are ...
  • Impressive beautiful lens indeed. Thnx for sharing. It would be great to see some comparison shots between your three primes (2.4/20 - 2.8/20 and 4.0/20) at F4 and at F8. And wide open to show the ...
  • I think the DFA on a crop camera makes little sense, it is designed for FF. The DA already is a very good lens, and much lighter and cheaper. On APS-C even my M20 is an extremely good performer at ...
  • A Pentax branded Z7 equivalent with K mount. I accept it will have a bit thicker mount but it offers maximum compatibility with all my glass, state of the art AF capabilities and top notch MF ...
  • Replied in Pentax K-1
    DFA 28-105, great kit lens, everyone should have bought this together with the K1. K28/3.5, cheap available on Ebay, light and robust, sharp corner to corner, very nice color rendition.
  • Could anybody who owns one of these beside the new 21 share his/her experiences about the differences in IQ in real world use? The older ones already had a good reputation, at least stopped down a ...
  • Replied in Predictions
    Bringing a K2 & K4 MILC of course demands R&D capacity. But that technology is the future anyway and Ricoh cameras already use that. So the camera R&D cant be that big issue. But the huge ...
  • Replied in Predictions
    Life line still is the K mount and those zillion K mount lenses. A K-mount MILC FF K2 and APSC K4 with a good EVF and all the advantages of on-sensor technology besides the dslr lines is the way ...
  • I think this is the right way to do. A lens is just one element in the chain between object and final JPG. So is the sensor, so is the software.

    But, does this also mean that discussions about...

  • Yep, that for sure is a real advantage, I totally agree with you. But that is less than 5% of my shots. When I take portraits I use an 40 years old MF 85mm lens, use focus confirmation, continuous...

  • It indeed is compact compared with its Nikon DSLR sibling, but compared f.i. with a HD Pentax-D FA 24-70mm F2.8 ED SDM WR it is not, and that lens costs half the price. I think the advantage in...

  • It would be great if we Pentaxians would have been surprised with a finished review of "the best DSLR of the year 2021", with the latest firmware and the use of the electronic shutter :-)   A ...
  • As Keith mentioned, these are optically the same. But there is a difference; the 1.8 has one stop between 1.8 and 2.8, I guess 2.2 or so. This one click down shows the six blades a bit closed with ...
  • Ricoh particularly isn't a small company. Besides PentxForums DPR also is an important platform for their reputation and marketing. I wonder in the first place why Ricoh does not supply and ...
  • No heart feelings here, I don't own either... But from a point of view of "looks", I prefer the Sony-design: I like the sharp A7-schnitt over the plastic rounded dslr-look alike Canon. The Sony...

  • Replied in KP is too good..
    Because my KP still is too good for what I am doing with it. But one day, when it fails it is time to replace. The same for my K1ii. I own about 30 K-mount lenses that I like to use from time to ...
  • The little Tokina served me years at film cameras, it is a nice reliable lens stopped down a bit. I put a thread on it on Pentax Forums compared to my other wide angles. You can find it here: My ...
  • Dutch summer landscape during a heat wave few years ago. Taken with a K1ii and Tokina RMC 17 mm at F8.
  • Without reading all replies, an explanation might be: Camera steady fixed in a tripod and 2s timer results in a non shaking camera / lens body. So the shake must be caused in the sensor itself. In ...
