Quote:Sorry Wim, no one was referring to a Laowa Macro lens. There are many other options for 15/4 FF lenses, some of them need to be stopped down. I agree the 15/4 Laowa is not great, the shift option is a joke and the handling is according to it's price (compared to serious shift lenses)
I agree, comparing different systems and creating "equivalence" simply doesn't work. It only would work, if everything could be scaled the same way, but pixel densities (as well as pixel arrays: X-Trans and Foveon sensor also are APS-C, not just the normal Bayer patterns), lens tolerances, noise behaviour (and strategies to minimize noise) are not enlarged the same way.
No need to apologize, I wasn't too clear I think on why I compared those two.
And you are completely right about how equivalence doesn't work, not now, and not in the past .
Kindest regards, Wim
