Glad you see the difference I was talking about the DOF being greater with the 50MP and following off faster from the focus pt. with the 50/1.4.
About the sharpness which I know you don\'t care about, you have wrong what I and other people were saying about the 50MP. I said the sharpness in the middle of the frame was only slightly sharper with the 50MP BUT it remains sharper acrros the frame better than the 50/1.4 except by f8 they are simialar in the corners. When I said this I was referring to infinity distance test I did earlier using a wall of a church at infinity distance to test sharpness. Here is the link to my sharpnes test: https://www.fredmiranda.com/forum/topic/864916/1
Also, the very extreme corner lack of sharpness anomaly of the 50MP does not show at f5.6 and smaller apertures. In typical large DOF landscape shooting at f8 you would not see this anomaly and the sharpness of the 50MP being more consistent across the frame would make it better for pano\'s. This is why there was an article in Outdoor Photography last year where the guy was using the ZF 35 and ZF 50 MP for his landscape pano work. Also, tale a llook at Andi Dietrich\'s 50MP and 50/1.4 comparison distant landscape shots and you will see the better sharpness at that distance.
Also, as people know the 50/1.4\'s sharpness at portrait distances is a lot softer than the 50MP.
I look forward to seeing shots which show this better volume.shape, 3-d thing you so desparately seek.
I think you need to take some comparison shots at more stopped down apertures like f8.
I took some landscape and cityscape comparison pictures yesterday too at f stops from f2 to f8,f11. They pretty much confirm what I have said about the DOF transition to OOF.
Also, if you take pictures with some troublesome bokeh like backlit leaves, the 50/1.4 will render worse more nervous/uglier bokeh than the 50MP.
BTW, I am not sensitive about 3-d definition. As an engineer with a Masters degree I get frustrated when people can not analyze better in technical lens drawing terms what their forming their opinions and feelings when viewing a picture instead of using vague higher-level subjective descriptions. I got frustrated trying to figure out what you and Philippe are talking about in terms of real lens characteristics. To me its similar to trying to find out why my girlfriend is upset but she herself doesn\'t know exactly why.
I am more sensitive to cliqueishness that goes on here in this forum thread and the forum in general but I will just try to ignore it.
