  • Not that I'm really in the market for an APS-C given that I'm using the K1 but I'd hope this button can be reassigned. IIRC. SR is automatically off when using remote release or timer which is a ...
  • That's possible. But the lens isn't new and probably doesn't need to be certified, the PSU is already covered in certification marks. It would make sense to say charge the battery in the camera by ...
  • That looks like a USB power adapter but there is no external charger. It's been stated that the camera supports battery charging of USB but it may not provide a separate charger.
  • Glad to have been the catalyst - I would never have asked about a non connecting mount.
  • <tips hat> I tried Jupiter with the DFA* 85 https://www.dpreview.com/forums/post/64221087 Obviously way too small to be meaningful but at the same time what resolving power.  Saturn + rings was a ...
  • In EU countries there is VAT but no supplementary import tax on digital cameras - which are still treated like computer equipment rather than optics.  It used to be the case that something which ...
  • If you work the lever on the lens with your finger you should see it stopping down, you can then check that it works mechanically. But from what you're saying the camera will drive it without the ...
  • I have pulled out of buying things online when I found there were hidden charges. Not just taxes, but I've gone to buy tickets and there's been a 5% booking fee, a £10 per person handling charge ...
  • I have to admire the man's dedication. Though I wouldn't want to engage him in conversation !
  • OK I got out my FA 50 and tubes (which actually say Asahi Pentax on them but I've never thought were "real" Pentax ones).  With no electrical contacts the camera displays F_ _ to say it can't get ...
  • That is usually the rule - sales tax applies to locals. If you buy from the UK or France and ship to the US there is no VAT payable, but someone in the US may have to pay tax as if they had bought ...
  • If there are no electronic connections the camera can't control the aperture. Just as a diagnostic thing try .... Oh you've done that :-), and if that works you've done the menu setting for "non A ...
  • Even that is subject to translation errors. One can take it to mean "the camera will be 299,999 yen or a little less" in implausibly large increase over the previous model, more the K1 and 3x the ...
  • The price guide for Japan is 2/3 of the K1's price in Japan. The idea of it being more than a full frame camera with tilt-screen and GPS is daft.
  • Replied in ISO 1.6M
    Not really. as a thought experiment...with one pixel. At the top ISO there still must be enough distinct levels to make a picture. Let's say 100. At top/2 the pixel counts to 200, at top/4 it ...
  • Replied in ISO 1.6M
    In theory, the decision "do we say the top is 819200, 1638400, or 3276800?" is based on some fixed quality, and not the whim of marketing. So yes all the lower ISOs should ripple up one or two ...
  • Replied in ISO 1.6M
    It does.  Think of it as "my car has a top speed of 150 Miles per hour / 250 KM per hour" "But you never drive that fast". "No.  But at the speeds I do drive the car isn't working especially hard ...
  • A GPS unit and a long piece of string - A GPS pendulum would record points along a straight track .
  • I have taken up drone flying this year, and the drone seems to use a very simple and cheap component which has pitch, roll and magnetic field sensor combined with inertial sensors. It has to be ...
  • You cross posted this, so I'll cross post the response Those are all standard in what comes back from GPS chip. It looks like this $GPGGA,191506.112,YYyy.6457,N,XXXxx.1809,W,1,03,6.6,156.0,M,47.6,M ...
