As a watch enthusiast, I sometime wish for more than 1:1 magnification for those detail shots of movement parts. I used to get by with the Nikon D50 and a micro-Nikkor 60mm but nowadays I'm using a Sigma SD9 which does have a lower sensor resolution - i.e. smaller sensor and bigger pixels than the D50. Anyhow, I read yesterday that a regular (not close-up) camera lens can, with suitable adapters, be attached backwards onto the front my Sigma 50mm macro lens.
It so happens that I have two lenses left over from the "good" old days (early 80's):
A Carl Zeiss 50mm f/1.8 Pancolar
A PMC 28mm f/2.8 Super-Paragon
The question is: which one do we think is better for the purpose of obtaining more than 1:1 magnification?
[Edit: by "better" I mean greater magnification but without excessive vignetting, or insane exposure times, etc. etc.]
best regards,
Ted
