Quote:I take this as a "what is this good for?" rather than a "does anyone use it ... is it good?"well, it would address a lot of issues that people have complained about with Sigma lenses, i.e. the off focus (especially if your body can't do microadjust), sometimes lens firmware incompatibilities when new bodies come along. Then it seems one can tweak other settings too for optimal use like the OS, where maybe it might make sense to have different parameters for FF and crop sensors?
I principle, this is not a bad idea. Rather than have people sent their new lenses to
Sigma and have Sigma adjust the lenses on Sigmas cost (under warranty), Sigma sells
a device to calibrate yourself. It will allow you to adjust the stuff that is adjustable
with firmware changes. (It will not repair mechanical faults, of course).
So, I see this more a marketing idea (quite clever though) than something
I would want to use. On the other side, the capabilities are better than what you
can do with microadjustment in-camera. So, it is indeed not senseless.
I assume, it will only work with the latest lenses of Sigma.
Just my thoughts ... Rainer
