Just played around with older equipment with my 7D: Soligor bellows M42 + Chinon 24/2.5 M42 in retro position + EF-M42-adapter with AF confirm.
I'm planning to go for insect eggs this year and the magnification of this combination looks promising: 4:1 to about 8:1. DOF is almost non-existing of course. But bokeh CA (lateral CA) of this lens is very disappointing, stopping down to f/5.6 doesn't help.
Do you have a recommendation for an "affordable" manual apochromatic lens with focal length 24-50 mm? Mount doesn't matter that much, doesn't have to be a very fast lens, f/4 will do.* Affordable means: lower 3-digits in Euro.
My knowledge about old-fashioned lenses may be described as "non-existing". If I'm delusional about the price range, just drop a word.
Ciao, Walter
*EDIT: Field curvature isn't a big thing either. Focus stacking will be used.
