[?] - Problem with Fisheye Nikkor 10.5mm 1:2.8 + Can Nikon D90

  • Hello everybody,
    I'm new with krpano and virtual tour also. I use Can Nikon D90 with Fisheye Nikkor 10.5mm 1:2.8 to capture images and use PTGui to stitch all images (often shoot 12 images for one place).
    But when I load images to PTGui, it automatically detects my lens at Fullframe 10.5mm (focal length) and 1.523 (multiplier), I manually select circular and value is only ~137 degrees *sad* and I try to ignore this value for stitching progress then create panorama with krpano tool; the result: the view of panorama is lean from left to right. *confused*
    I know that ~180 degrees for circular lens type is the correct value for making a panorama picture.
    What's happen here? How can I setup my Nikon and fisheye lens to match the correct requirement for panorama.
    Thank you all.

  • what pano head are you using? are you sure you have the NPP correct? with a D90 and a 10.5 i dont think you need 12 shots. I am pretty sure you would need only 6 around @60 degrees each and 1 up and 1 down if you want a perfect nadir.

    maybe upload your source images and your ptgui project file to rapidshare or something let some of us take a peek and see if you have things setup right.

    found this the D90 has roughtly the same size sensor as the D70.
