I probably added the D810 as the typo, but whether D810 or D850, you're still taking full-frame cameras with high mega pixel sensors, so you're still talking about new lenses to go along with a full-frame camera. You might find the D750 or even either of the two Z models already released as better options to the top-line D8xx. Or even the D7500. Many who jump to the 46 MP range of the D850, they start having issues with the file sizes and the size and processing power of their computer. The quality of the lenses also factors into these bodies where the resolution of the sensor can highlights flaws in lessor lenses that were not seen when mounted to other cameras.

I respectfully disagree. Theoria Apophasis (aka Ken Wheeler) is one of the most knowledgeable and professional photographic bloggers currently publishing. I’m sure others will disagree, especially those whose gear he demeaned. He makes a practice of acquiring lenses he plans to evaluate and does not accept favors or gratuities from manufacturers or major vendors. In short, he is nobody’s “boy” and nobody’s fool. He is aware he has many detractors and, frankly Scarlet, does not give a darn. He calls it like he sees it after detailed in-depth analysis. I respect his opinions despite his rants.
