  • FOV, 7mm (7-14) vs 7.5mm FE/defished.

    This was an exercise in FOV only between the Panny 7-14, at the 7 end and the Samyang 7.5 FE, fished and defished.

    The camera was in the same place for both shots set at f5.6 with MF.

    I used Fisheye Hemi to defish.

    Interesting results....I thought.

    As I use the 7-14 at the 7 end, 99% of the time, I'm wondering should I keep it.....Opinions please.
    If one is looking for UWA then surely the FE defished is the way to go, and at a fraction of the price of the 7-14.

    Panny 7-14 at the 7 end.

    I use my 7-14 for precise framing, it's a likely to be at 8 or 9mm as 7. I also use it at 12-14mm to avoid the complex distortion of the 12-60 at the wide end.

    I think a lot of people realise a defished fisheye shot will be wider than a shot at 7mm. I very rarely defish as I wonder if there's any artifacts being introduced by all the pixel juggling needed.
    It's the image that's important, not the tools used to make it.

      How interesting - thanks.

      I rather like the last, it reminds me of the underground.

      The first shows the textures well and offers a much better image to my eyes.

        I have the Samyang 7.5mm fisheye, and it's become one of my favorite lenses. It's tiny, quite sharp, inexpensive, and a whole lot of fun! I've experimented with some de-fishing software, but almost always leave my images fishy. I don't take architecture photos very much, so I don't usually find the distortion objectionable. I even used it for some photos of my mom's wedding, and she was happy with the results. Samyang use a near-stereographic projection for their fisheye lenses, which produces less distortion than the more typical orthographic projection.

        Thanks for doing the comparison!

          There is still some distortion in the de-fished version, but it's useful to know maybe for emergencies

            I had a friend that avoided buying the 7-14 by doing the same with the 8mm FE. I use the 8mm, 7-14 and 11-22 to do interior work but have never defished the 8mm. Usually I crop what I need out or leave the distotion in. It would come in handy for closets and such. Thanks!

                Hi Barrie

                It's great to see everyone here again and yes the health has improved. Thank you for asking.
                My arm is back to the point that I can handhold again but I have to watch how long I let the rig hang by its grip strap. The rest of it, well it is what it is and I do what I can.

                How have you two been? I see you are enjoying your EM 1.

                I hope your Christmas is a great one.
                Jim
