Roland Karlsson's recent activity

  • On Mars maybe? Or some other place where there is no atmosphere?

  • So - what is that rocket doing?

    Lifting a little and then landing?

    When is that capability useful?

  • Referring to Einstein is always right! :)

    There is a kind of truth in what you say though. Maybe somewhat exaggerated. Einstein was referring to faults and misconception in our thinking. Like the...

  • "Thinking out of the box"? This one is mainly going to be used by tech nerds. I guess.

    BTW - this moving around and forcing different parts to be in focus demos are so boring. There has to be much...

  • Somewhat steep price. But ... maybe useful. The guess in this thread is that it gives a 2.5 MP resolution, which is Ok, if not outstanding. The previous camera was not OK.

  • Yes, you can make everything in focus. But, just as you cannot get super thin DOF, you cannot get super deep DOF. Thinnest DOF is from F2.0 and largest DOF is from maybe F8.0.

  • @HowaboutRAW. Yes, you can have a phase plate in the lens, or even in front of the lens. That is much more computing intensive stuff though.

  • So - give me some facts! How many native pixels do the 1" sensor have? And how many "lytro" lenses do the camera have? That is all that counts.

    Do the 1" sensor have 50 MP?

  • It is not the lens that doe4s it. It is probably a normal lens. There is a micro lens grid with several pixels under each micro lens over the actual sensor.

  • It is not the lens that does it. It is probably a normal lens. There is a micro lens grid with several pixels under each micro lens over the actual sensor.

  • Exquisite colors. Well balanced. Even the border.

    And, of course, totally priceless man.

  • I think you are mistaken. The wax lookalike images that you see here is not because it is digital. It is because the camera use strong and cheap noise cancellation.

  • Commented on GPB photo in bobn2's photo gallery

    I guess that the lighting in the stand is tungsten. So ... then it is only to correct the photo for tungsten, and then you will get everything blue.

  • Xz-2 is nice, but it has 4x zoom, not 24x zoom. So ... not comparable.

  • The lens would be gigantic. And the virtues of less pixels is greatly over rated.

  • Nostalgia! The sensors where much worse back then. A modern 1/1.8 with BSI would better though, or a 2/3.

    But, the camera has a whooping 25x zoom. A 2/3 camera lens with this kind of zoom range...

  • Now, just to get things right. This is a small sensor camera. It is 1/2.5 inch. So - it is noisy, even at base ISO. We know that. And there are lots of other cameras like this.

    But - the problem...

  • Judging from the images, even at base ISO, the quality is not enough for having any need for RAW.
