The Lens details of a series of images taken by Steve Cushing on mirrorless camera.

Fitting has no mount and has a 42mm Flange Distance - this lens will fit and achieve focus to infinity mirrorless cameras even on DSLRs.

Lens History

The Pentacon AV 100mm f2.8 is another projection lens for 35mm Slide Projector. It was used in slide projectors with 42,5mm and 52,5mm mounts. Its optical design is the same as the Meyer-Optik Görlitz Trioplan 100 mm f/ 2.8 and also the Bokeh is the same, it was made by the same company as Pentacon own MeyeOptic.

If you are using a trioplan it is for the artistic effect as this lens design is not pixel perfect, indeed sometimes even the focus peaking does not work on my camera when I use a Cooke triplet lens as the image is not short enough. But who cares, this is an Art lens.

Lens In Use

• Optical design: 3 elements in 3 Groups (Cooke Triplet).
• No filter mount.
• No aperture.
• No helicoid.
• Plastic barrel.

Summary

Shooting with the lens reminds me of shooting with Helioses, since the light is unforgiving. Flare from wrong direction, and your shot is ruined. Little adjustment of positioning, that would make almost no difference with "real" lenses, and the shot is amazing!

The funny thing is I can't create creative images like this even with my expensive native super-sharp canon RF lenses.

Rarely is learning so much fun!
