I shouldn't comment on this thread as you seem not to read/consider any of my previous posts but I will do it just one more time to say that if you refer to "common sense" you should also consider ...

I wouldn't deny this "compensation process" as there is no documentation on it but if it is already there it has to be a "generic" one not adapted to the actual lens being used and when present ...

No surprise as the focus indicator works together with AF phase detect requiring the maximum light as possible and focus shift comes in and can grow as you close down the lens because this only ...

Can you please what you mean by "depressing the PV button to account for focus shift"? As PHXAZCRAIG refers in a comment bellow the PV button function is to "preview the depth of field" not ...

Maybe we should stay midway and say that even if Nikon release a new version of the lens yours fits your needs perfectly and you don't see any advantage to change  but, besides what you point out, ...

Is the latest firmware version supposed to address the compatibility with the D850 and is that listed by Sigma?

Don't be surprised as the "jump" from 36 to 45 Mpx  is not as big as that in terms of noticeable difference of quality for image sizes within the comfort zone of the D810.

It's difficult to say if you can "see" but if so and you're ready to pay the price (because I don't doubt it will be quite high) don't hesitate and go for it. But just take another example outside ...

Let me tell you one thing: one of my best lenses is a (not a macro) several decades old Karl Zeiss 100mm F:3.5 for the Hasselblad and on the same line if you go to Thom Hogan DSRLbodies site and ...

From the customer side that would be the ideal situation but in real life when a manufacturer introduces a new camera takes into account their lens park and foresees to sell more of their own ...

…and in its Hasselblad competitor model, by the way...

Take care because if they read your post you risk they offer you a cat… :-) :-)

Sorry, I don't want to be rude but your answer risks to be the one that seems "acid about other peoples opinions" sending me back to school when I didn't even said landscaper1 was wrong ("you'd be...

@landscaper1 - you'd be right if the sense of the tittle is in terms of future time but as I understand it is in term of dedicated kind of photography, i. e., D850 is so versatile that with it you...

I do understand that if you do an extreme crop you end up with a smaller file with 11 Mpx or even less but IMHO the point is that as soon as you start cropping on one hand that is not the same as ...

You got me wrong as when I refer to an adapter is to use F-mount lenses with a new Nikon mount and the one for Nikon 1 proved it can be done and work in a satisfactory way. A different story would ...

@ landscaper1 - Sorry to enter your change of messages but do you know of any expression "more superlative" than "The Best (…) To Date"?

Aren't you taking "downscale" as a synonymous of "crop"? If not why talking about 11Mpx? Shouldn't the two cameras shoot in order to get the same framing instead and when you talk about downscaling ...

@ G G - And if you took good care of it is still functioning and the SLR cameras that came afterwards may be more sophisticated and full of electronics but with the same grade lens and film will...

I wouldn't sell the IQ180 either but if I had it maybe I could make myself a surprise and offer me a D850 for occasions… with some caution on the lens side it wouldn't be that expensive compared to...
