I don\'t think anyone ever really said that there would be no such thing as usable RF wides. I think the bulk of the premise is that if your quest is to use RF\'s, your edges and corners are going to be even more challenged than their SLR counterparts by virtue of the closer distance to the film plane and the correspondingly steeper angles involved @ the steeper you go, the tougher it gets.
From that, there was simply an avocation to be realistic in your expectations of what could be achieved by RF glass in the WA/UWA range in the edges and corners. While there certainly are some usable RF wides ... the reality of their performance as usable is in many cases a far cry from excellent or superior in absolute terms or in relative terms to excellent SLR glass or likely forthcoming native glass. Setting the bar at \"usable\" and getting really excited about it just seems kinda antithetical to the capabilities of the A7R ... but I guess that\'s just me.
Sure, it must feel good to know that you can now use your RF glass on A7/A7R (although I think the Rokkor\'s are strong benefactors here too), and if your quest is RF glass usability then I suppose you\'ve reached your goal. If your goal is excellence, then I think the quest for finding excellent performing RF glass on 24x36 remains very much alive. The A7/A7R provides additional usability for RF glass, but it also sets the bar pretty high to it\'s capability as well. We all set our own bar where we want it. I just find \"usable\" to be a rather different bar than I normally aspire for.
The beginning of reality for me is the IQ of the image. If we are looking for the best possible IQ across the entire frame of our 24x36 format ... RF WA/UWA glass may not necessarily be our best friend on the A7/A7R. Finding good RF WA/UWA friends to play nice (and their likely are some) with the A7/A7R will be an ongoing endeavor that we all will decide who we want to play with based on our wants/needs/goals.
