      Hello chaps,

      I have the feeling there is something wrong with my new Sigma 8mm f3,5.

      Please check the following photo:

      should the border not touch the 2 vertical edges?

      am I doing anything wrong to get that top and bottom trimmed?


      Thanks

        Hi Imbu, I am affraid, there is nothing wrong. The image circle of the 3.5/8 sigma is bigger than the one from the 4/8 sigma. Even on my older EOS350 the 4/8

          Hi Imbu,
          I am affraid, there is nothing wrong.

          The image circle of the 3.5/8 sigma is bigger than the one from the 4/8
          sigma. Even on my older EOS350 the 4/8 sigma image goes over the the
          sensor. The sensors are getting smaller and denser too.
          All you can do, if you want the full circle is roll the cam to 60° instead
          of 90°. Shooting diagonally will give you more image to play with and you
          might get away with 3 shots if you have precise indent marks.
          Later, when stitching rotate your anchor image first and the others will
          follow the anchor image.

          Bend your bracket or get a lens ring.

          Cheers, Milko

            ... or tilt the camera up by 5 degrees. That will give you coverage of
            the zenith at the expense of a larger hole at the nadir. Losing part
            of the view of the tripod is not usually something to lose sleep over.

                Also, by the looks of it, the new Sigma fits Nikon D70 models like an
                italian leather driving glove now. Which was not entirely the case
                before. Nice, nice.

                  just "touch the verticals" with the sigma.

                  I did not know the new sigma was "bigger".

                  I shall give it a try with bending it to 60% or tilt 5% upwards as you
                  suggested.

                      Hi John and Group

                      I have just ordered a new 8mm f3.5 to use with a 5D, is this new
                      image circle a problem or an asset?

                      (I am currently using a 360 precision which gives very accurate
                      results with the 15mm, although I, like some others find that PTGui
                      does place the zenith shot in the middle of the pano editor .)

                      I am going on a shoot to india for 11 weeks and may only get one day
                      a week to shoot panos for fun so I want to travel light, I am
                      planing to use the 5D in landscape format on a very simple set up,
                      i.e. a modified metz flash bracket that will allow me to mount the
                      lens' nodal point on the monopod spigot and to hopefully shoot in 3
                      or 4 shots I find that a tripod is too invasive in many
                      situations.... any tips from the mono pod/pole specialist?


                      Many thanks in advance

                        Sigma 8/f3.5 combo - the resolution of resulting pano will be too

                        Totally agree that monopod is much faster and less intrusive than
                        tripod, with some practice you will find that the shooting pano with
                        monopod is fast and easy.

                          A friend of mine just returned from New York where he wanted to
                          experiment with high resolution panos using a 39mp hasselbad, he
                          was stopped from shooting in central park and other places because he
                          looked professional and needed a permit!

                          One location under one of the bridges an officer appeared from
                          nowhere and charged him $25.

                          When you say fast and easy, the few Ive tried with the 15mm dont line
                          up, maybe more manual control points have to be added??

                            Well... everything depends on your standards of quality. I think that
                            6000x3000 is an absolute minimum for full screen panos and it is
                            better to have bigger source file (I mean - maximum size that can be
                            generated by PTGui) - it will let you to apply noise reduction and
                            sharpening effectively and after that to downsize and produce clean
                            image.

                            Regarding the process of shooting with monopod. Just keep monopod
                            vertical (bubble on the pano head helps a lot) and provide enough
                            overlap - simple. Never experienced problems with stitching monopod
                            panos, it is much easyer than handheld technique which is also pretty
                            easy (I was shooting a lot HH with diagonal fisheye).

                            This is a sample of monopod pano: http://pano.1drey.com/panos/egypt/

                              i m still using d70 at the moment. the d70+8mm combination can only
                              generate a pano with 6000x3000 or slightly less. definately a bit too
                              small to edit full screen qtvr.

                              ... Fatchai, With the much larger sensor on the 5D, it seems obvious that you are going to get a larger equirectangular image out of PTGui than from a D70.

                                Fatchai, With the much larger sensor on the 5D, it seems obvious that
                                you are going to get a larger equirectangular image out of PTGui than
                                from a D70. However, if you take a close look at the camera
                                specifications at dpreview.com, say, you can calculate the approximate
                                physical pixel sizes from the image dimensions and sensor sizes.
                                Perhaps surprisingly, it turns out that the 5D has slightly bigger
                                pixels than the D70, and so PTGui will generate a smaller panorama from
                                the 5D images than from the D70 images, given the same lens. I don't
                                have a 5D or a D70 so I cannot provide any actual panorama sizes.

                                  Here is the simple version:

                                  I use a D70s + 10.5mm. It projects 86.63 degrees in 2000 pixels on the
                                  small side.

                                  I used http://www.frankvanderpol.nl/fov_pan_calc.htm to get the FoV.
                                  Choose your camera, your lens, press "calculate image" and read the "for
                                  fisheye lens" table.

                                  If 2000 pixels are available for 86.63 degrees, then stitching multiple
                                  together to 360 degrees will give you (360/86.63 x 2000) = 8311 pixels.

                                  You can do the same for all your combos..

                                  Serge.

                                        There is also the often-overlooked fact that there is much more "black"
                                        area around the circular 8mm image with a full-frame camera image than
                                        there is with a smaller sensor in a 1.6:1 or 1.5:1 camera. This means
                                        that fewer of the pixels are used in the final image.

                                          If you know the (effective) Horizontal Field of View of your lens (in
                                          degrees), and if you know how many pixels of your camera's sensor
                                          this covers, you can calculate the number of pixels per degree your
                                          system can capture.

                                          After this, simply multiply that number by 360 to discover the
                                          maximum "optimal" width of a panorama that was captured with that
                                          system.

                                          For me, a 4000px wide equirectangular seems to be a fair compromise
                                          for a "full screen" panorama.

                                            John, what is the size of images that you used, please take in
                                            consideration that the maximum image size from camera 5D is
                                            4368x2912, if your test images are 3168x2112 or 2496x1664 those must
                                            be resampled at 4368x2912 or apply some multiplier on size of

                                                choice?

                                                Re the Nikon, how do you set the aperture on it if using a canon
                                                adaptor? I thought it would only work in manual mode.

                                                I havent time now to source one and trim the lens hood :(

                                                With regard pixel counts, surely careful upsizing in ACR and other
                                                software will give a lager usable file if needed?

                                                I have only been experimenting with these VR panos for a few months
                                                and find every one great fun.

                                                FWIW I have found that with the canon 15mm, using +20 vignette in ACR
                                                really helps blend the images.

                                                One last question, how do you make a template in PT Gui?

                                                  Most people just stick a bit of plastic into the lever on the back of
                                                  the lens mount and use it with a fixed aperture. Unlike most Nikon
                                                  dSLRs, Canon dSLRs will meter without a connection to the aperture
                                                  control.
                                                  Michel Thoby worked out a method where you could rotate the lens on a
                                                  converted adapter to alter the aperture, but it requires a fair
                                                  amount of machining skill.

                                                  If the detail isn't there in the first place, upsampling isn't going
                                                  to help at all. All upsampling really does is stop images pixelating
                                                  when viewed close-up.

                                                  Any PTGui project file can be loaded up as a template, there's no
                                                  need to 'make' one as such. Note that a template is only going to
                                                  give you a starting point, you will still need to generate control
                                                  points and optimise unless using a hyper-accurate head such as the
                                                  360Precision.

                                                        :-D You can use it at 10 mm to do monopod shots like 8mm on APSC
                                                        sensor, up to 14mm to shoot 5 pictures around tilted down and 1 up, or
                                                        to 17mm to have a 8shots full sphere in high detail. :-)
