Tamron are not 'class-leading' manufacturers

So, this is a better lens, but considerably more expensive.  Possibly the latest Canon and Nikon 135 system equivalents will have caught up to this level of performance?  (Not at f/2, obviously, but putting that aside.)

Then there is the rather important fact that the Zuikos don't work on any APS-C or 135 body in any case.  So really it is a bit irrelevant to compare them as they are not options in themselves -- you must choose a system that will use the Zuikos if you want them.

The point I was making was not that 14-35 is of lesser value lens, the point I was trying to communicate is that Tamron is not a c-grade optic either.

No, but it is not "A-grade", either.  Tamron do not produce lenses to the same level as the high-end Canon and Nikon offerings.  (Or at least I am unaware of any Tamron lens that falls into that category.  They always have more compromises but cost significantly less.)

And this Tamron lens has worse optical issues than the FT lenses you were comparing it to -- you appeared to be implying that is was of comparable quality (or was when stopped down).

Looking at these test results I can not say I am not impressed,

Tamron 24-70mm F2.8 VC Studio Tests

But as you say, it is irrelevant to compare them outside their systems. And since my Nikon 24-70/2.8 hardly gets any use on FF camera, I don't think I would ever have an interest in 24-70/4 variant if there was one.

The main advantage is that this provides an alternative option to those who do want such a lens.  The FourThirds system has not attracted enough third party support to provide many alternatives, and Panasonic did not produce a large range of lenses.

Tamron appear to be developing MicroFT lenses, however, so it would seem that users of MicroFT systems have a widening selection of alternative lenses.  (Sigma are making APS-C lenses in MicroFT mount, as they did for standard FT.  This is less useful than producing lenses specifically tailored to the system sensor size.)
