New Sony 85mm GM tests (possible autofocus issue report)

As with any new product there are always some reports about annoyances and possible issues. The 85mm GM lens first was “under suspicion” for a possible mechanical issue causing scratches inside the autotofus ring. But it turned out that what you see is just the lubricant (article here). Now we got another possible autofocus issue we have to investigate. Diglloyd claims:

“Right away with the Sony 85mm f/1.4 GM, I noticed a disturbing tendency for Sony A7R II autofocus to be off enough to seriously degrade results at f/1.4, enough to call it a “2 stop error” in some cases, meaning at least f/2.8 would be needed to obtain the quality that ought to have been captured wide open at f/1.4. Or put another way, an error that turns a 42 megapixel camera into a ~12 megapixel camera. Or something akin to that.”

Let’s see if that will turn out to be a real issue on all lenses…
