something like a 50-100 f/5.6 macro 1:1

the use case is product photography in a studio with controlled lighting

I'd like to work with one of those lenses, but instead I need 3 lenses, 50, 70 and 100 macro.

feature Wishlist:

  • internal zoom for lens-mounted lighting
  • no aperture ring, it's not useful for studio
  • tripod collar for balanced mounting
  • weather sealing not required
  • absolute position focus ring and clutch (like sony 90mm macro)
  • some kind of mechanism on the focus ring to limit focus range to any point

Hi Eric, there is always interesting research on innovative optical trains . There is whole body of research in peer reviewed papers on attempts to use some of the existing optical trains in a zoom system such as catadioptric, cassegrain and petzval to name a few.

IIMU several German firms made a few small production runs of these zoom systems on a photographic scale c. 1895 - 1930 ish of the last century .

There are 406 citations for " zoom + lens " in the NIH database with many interesting scientific papers on this subject matter.

Here are a few individual citations:

Extended the depth of field and zoom microscope with varifocal lens

https://pubmed.ncbi.nlm.nih.gov/35773323/

Three-component zoom lens with fixed position of optical center

https://pubmed.ncbi.nlm.nih.gov/31158198/

Automated design of a slim catadioptric system combining freeform surface and zoom lens

https://pubmed.ncbi.nlm.nih.gov/35472951/

BTW You must keep your 2.8 capacity young man, photography is an art,.

LOl Don't hover at 1:1 MFD trying to play hero - back off a little and take in nature's art

May the photons be with you.
