One of the biggest misconceptions is that any talk of 'equivalence' is just code for 'why my sensor/lens combo is better.' That's not what it is.
It really just describes a
relationship between formats that you can use to decide, for the shooting you want to do, what would work best within your budget, and maybe how much difference a format change would make.
It's also most important for mounts that share a FF and aps-c sensor, so you know how your current lenses will perform on the new format you buy (aps-c or FF) which can also help you decide if you might want to buy/sell some lenses. Pentax may enter that scope soon, and then (I hope) a lot of first-hand experience will enter the arena and there won't be so many dust-ups based on what I suspect is really, under the scenes, brand wars.
It only becomes a p**ing contest when someone gets butt-hurt about a given comparison that doesn't happen to favor their combo in performance or $$. One of the by-products of those p**sing contests is that sometimes some people start to get irrational and deny equivalence, or bad mouth it as a sort of agenda - when it's really just a simple relationship.

But we never see FF is shxt because at 'equivalent' focal lengths the shutter speed is unasable do we ?
Why is that ?
Probably because only the truly clueless would make that statement (in the way you phrase it.)
Quote: WHy don;t we see FF is shxt get a MF camera is you want to control DoF and have good DR because at 'Equivalent' Apertures it leaves the FF dead in the water.
Again why not just what is magical about FF euivalence ?
Couple reasons:
1) lack of many affordable really fast lenses for MFD that would fully realize this advantage,
2) overall cost of the system - $ delta between it and entry-mid FF is about 5x or 10x what the delta is between aps-c and FF,
3) up until now, low-light performance and AF and FPS have been underwhelming in MFD and don't meet a lot of folks' needs, and
4) size. It can matter. The body is big, the lenses are honkin'. If you're not shooting on a tripod it's not ideal for a lot of applications.
MFD is really great for a couple things but it was never meant to be a general DSLR replacement.
