Sigma fixes Nikon D5300 lens compatibility issues

“The bullies at Nikon? Imagine that Nikon wanting to make sure all F-mount lenses work as advertised on their bodies. “

Then they give the communication protocols to Sigma.

Your type of thinking is typical of the bureaucratic mind that seems to be prevailing in the West these days, even the UK and US.

I agree they aren’t really bullies, just fixated on their short-sighted we-want-it-all business plan. A bit like Fuji and their unwillingness to handover the x-trans processing source code.

Self-defeating.
