  • Nice, as red as a poppy can be. If you do not object I will use it as a reference red for my papaver images, often struggling with that color. Met vriendelijke groet, Ernst No photographer's gear ...
  • Yes and the fact that Canon went for an unusual hybrid optical design. A mix of half a Plasmat and Gauss with an aspherical element. Less sophisticated but done before by Meyer in the Kino and ...
  • Yes, it will be a real challenge. Mr. Miyazaki made an elegant solution with the multi blades aperture bare in front of the lens elements. That way the optics could be buried deeper into the body ...
  • The challenge for MS Optical now is to get something similar for mirrorless models like the Sony FE mount at 18mm and the Nikon Z at 16mm register distance. The M mount has a register distance of ...
  • Thank you.  Meanwhile my elder sister gets more visitors than before this crisis. Something to worry about. The OM lenses I have got a permanent OM/EF adapter with a chip. Reversible though. Plus ...
  • snip + Converted compact camera lenses . Although some are still longer (less pancake) than the Canon EF 40mm 2.8 STM mounted on an MC-11. For example the Color Skopar 50mm 2.8 of a Vito which is ...
  • Replied in Sister's garden
    Met vriendelijke groet, Ernst No photographer's gear list is complete without the printer mentioned !
  • That sounds more like a loose element in the lens. Or with cam grooves and followers the last weared off. Met vriendelijke groet, Ernst No photographer's gear list is complete without the printer ...
  • The end stops usually act on the focussing ring itself. A slightly loose connection between focussing ring and the outer helicode, say 3 screws not sitting deep enough, might be the cause. If you ...
  • Very true but from a marketing perspective they better point to a Sonnar relation. As one designer already seems to have done. I am more interested in Willy Schade's thoughts about the development ...
  • Brian Sweeney mentioned one Zunow design as being related to the 7Artisans 50mm 1.5.  He is quite an authority on older Sonnar/Jupiter designs. I added three Zunow lens diagrams to the range where ...
  • The review on Philip Reeve's site is not flattering either. Especially the curved plane of focus is worth mentioning. Things get worse at longer distances. Bokeh not becoming either. One might ...
  • I expressed my doubts before about the Sonnar heritage of that 7Artisans lens: https://www.dpreview.com/forums/post/63619952 https://1.img-dpreview.com/files/p/E~forums/63619952/3bb42d4e1d0246c98d3 ...
  • Your experiment reminds me of the French cinematic term 'la nuit américaine'. Met vriendelijke groet, Ernst No photographer's gear list is complete without the printer mentioned !
  • Replied in 50's
    Mamiya must be the champion of lens mount diversity for its 135 film SLRs.  M42: TL and DTL lenses that are easy to adapt. M42 with a twist: SE lenses. Diversity in bayonets: ES, CS, E, EF.  ...
  • Replied in 50's
    If that first character after Mamiya-Sekor is an E then you will have a hard time to get it adapted to a M4/3 camera. The aperture is electronically controlled on the Z cameras. http://herron.50meg ...
  • Looks like a nice job to do by selecting flickr samples of said lenses and create a multi layer graphical interface to show the branches of optical defects + compensations and their relations to ...
  • Replied in 50's
    So you are looking for a kind of portrait/short tele lens on the GX85, approx. the viewing angle of a 100mm on full frame. You might as well look for C-mount lenses too then as many will cover the ...
  • Replied in Black paint
    I recall that feud between them. I also think a Dutchman sold a similar replacement black paint for the same reason. Reminds me also of the T-mobile claim on the color magenta; https://www.dutchnew ...
  • The Color Rikenon 35mm 2.8 of a Ricoh FF1. At 8.0,  covered sky Front cell focusing and triangular aperture. Next to the 3D printed adaption to an FE reverse ring, I added an extra ring on the ...
