So, DFO just like RC, noise suppression, Darbee , sharpening , motion control and other types of electronic processing all have applications that enhance the image . Any owner has a choice to use these various tools or simply turn them off . The vast majority do use RC most of the time, personally, I'd like to have the oportunity to see what DFO offers, if it's not adding anything , it's quite easy to turn off .
I see this feature being passed down the chain in the next round, the hybrid acrylic main element lens used in the other models have softer edges by design, this is where I see it being more beneficial. Still need a bigger screen/image to see the difference, on the average home screen 120" range it will be difficult to realize the benefits especially from normal seating distances .
Hmmmm, the ARC-F lens is marketed as a superior lens with crisp focus from edge to edge.
DFO is purely a marketing ploy and and unneeded one.
The only reason it has been done I think, is because the lens used on the 760 et al, is actually very good (better than many give it credit for) and they needed to have a visible differentiator between the 760 and 870.
On the 5000, people pay so much money they just accept they are getting the best lens anyway and won't even have necessarily viewed any of the lower models and probably don't care either.
I agree that on larger screens the extremities of the lens will be being used, but the lens (which is the best part of 10k to buy standalone BTW) has been engineered to resolve pixels properly even at those limits.
We all know processing can and does improve image quality, but machines with the ARC-F lens really don't need that sort of crutch.
The models with the standard 4K lenses would diubtless benefit a lot more from corner sharpening, but from what I have read it needs to be tailored to the lens in each unit, possibly driving up costs. However I think they could simply add a corner sharpening tool to the lower models and it would be nigh on the same.
No one with an 1100 has ever complained about the lens on their machines as far as I am aware. No DFO on those.
