I take this as a "what is this good for?" rather than a "does anyone use it ... is it good?"

 

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
