Lens Comparisons

Lens tests at around 2:1 to 1:2 would be interesting indeed and most tests that exist don’t cover that range. Whether the top of the top is required depends on other things though: Are the original takes

  • worth being copied from a content point of view
  • technically good enough
  • etc.

And what is the target size of reproduction. Mural or SocMed thumbnails?

Some lenses are fairly good in “standard” tests, e.g. the Sony lens rates very high at dxomark.com. It seems to have some issues that doesn’t put it on top for macro/reproduction. Same as the Canon RF 100mm lens with its infamous focus shift.

From what I recollect from looking at lens tests, most “better” lenses (for our purposes) are from third parties or speciality lens manufacturers.

Shopping around for a new lens, look for published MTF curves (and the resolutions involved). Bragging can be done with such curves and if the curves aren’t there, there might be nothing to brag about…

Good point!
Pretty much all my negs and slides were hand held at most likely no more than 1/250th second. And I think this would be the case in-general. So when enlarging detail, the original photo will be the weak point. However, it’s nice to know you’re capturing everything including film grain. There will be the complex landscape, cityscape or still-life captured using a tripod or fast shutter speed.

Photos I digitise along with digital camera images usually end up in Keynote/Powerpoint presentations on a 120" screen and I often “zoom-in”. With a 4K projector its nice to have the best quality image.
