I would not care about that any... for example, what relevance does the equivalence to FF - a format I've never been using and likely will not be using in any foreseeable future - have for me? Not any more than MF or LF for that matter. Of course, everyone's case is different...
I tend to refer to my lenses not by any FL or much less their equivalence to anything, but as "DA WIDE", "DA LONG", "DA WIDE FOR DARKNESS" and "DA ULTRAWIDE". There's also "DA LENZ TO PUT IN DA BAG JUST IN CASE", which is the 24-85. Soon maybe to be joined by "DA CURVED".
