NOTE: This image is a focus stacked image of "Canon FD 15mm f2.8 SSC fisheye lens and its original satchel" consisting of 7 images that were merged using Zerene Stacker Version 1.04 Build T2018-07-19-1515 (licensed). As a result, this image underwent digital manipulation which may have included blending, blurring, cloning, and colour and perspective adjustments. As a result of these adjustments, the image content may be slightly different than reality at the points where the images were combined. This manipulation is often required due to lens, perspective, and parallax distortions.

Additional Information

en: Canon 15mm f2.8 SSC fisheye lens and its original satchel.

  • Height of lens including rear cap: 77 millimetres.
  • Front diameter of lens hood: 73 millimetres.
  • Purchased this lens in 1980 and have used it quite often in confined environments.
  • The central resolution is quite good, but diminishes rapidly towards the edges and, especially, the corners. But this reduction of resolution far off-centre is a typical quirk of all super-wide-angle and fisheye lenses.
  • Works best when stopped down to aperture 8.0 and attached to any of my Sony Alpha 7RI..IV bodies via Novoflex NEX-CAN adapter.

de: Canon 15mm f2.8 SSC Fishaugenobjektiv zusammen mit der Originaltasche.

  • Länge des Objektivs mit hinterer Schutzkappe: 77mm.
  • Außendurchmesser der Sonnenblende: 73mm.
  • Das Objektiv wurde angeschafft in 1980 und recht häufig in beengten Umgebungen benutzt. Die auflösung ist mittig recht gut, schwindet jedoch deutlich hin zu den Rändern, noch mehr in den Ecken. Eine erhebliche Auflösungsverringerung abseits der Bildmitte ist jedoch ein typisches Phänomen aller Superweitwinkel- und Fishaugeobjektive.
  • Diese Exemplar kam in den vergangenen Jahren wieder häufiger zu Ehren, eingestellt auf Blende 8,0 und verbunden mit einem meiner Sony Alpha 7RI..IV Gehäuse per Novoflex NEX-CAN Adapter.
