Uhoh7 ... why do you keep insisting that people have been saying that RF wides are unusable?
Most folks have said that they will either be more challenged (vignetting/color shift/smearing) by the steeper angle in Zones B & C or that we\'ll have to be very selective @ which ones will perform well in the edges/corners, with realistic expectations based on their inherent optical projection design that may not produce optimal IQ without additional PP correction efforts.
The CV\'s seem to be doing rather well as a \"brand\". I suspect there is something in their design approach that plays well here. Maybe a certain amount of curvature/mustache etc. that they have incorporated for contending with Zones B & C (albeit intended for film) that keeps those angles of incidence within the limits of playing nicer with the sensor (lenses/toppings). Also, one might consider if they are capturing a near/far scene vs. predominantly infinity. They might be better suited for street than for landscape.
Of all that I\'ve seen so far, the CV\'s have caught my attention the most (as a brand/group) as being pragmatic RF WA/UWA glass options ... imo, they\'re worthy to explore with more fervor and microscopy to ascertain those applications to which they are well suited.
NOTE: It seems that I\'ve since learned that some of the CV\'s posted were actually cropped images ... thus my assessment of CV\'s may warrant reconsideration.
