I never saw Johnston's review but had ignored this lens thinking that it
was for small sensor cameras because of the "Di" designation. I looked
up Johnston's review and he thought the same thing and described it as
for small sensor DSLR's. But we were both wrong. Di simply means
"digitally integrated". "Di II" on the other hand means... well,
somehow it means APS-C size sensors only. This could be an attractive
alternative to the Tokina 20-35 given that it goes down to 17mm and also
uses 77mm filters. It also doesn't hurt that it's $50 cheaper than the
Tokina.

It's an opinion that a lens of that range is an optical compromise and
that better performing and faster lenses will have a different
compromise... namely, two or more lenses to cover the same range. I
note that Tamron does not attach the "SP" designation to lenses with
zoom ratios greater than about 5:1 and most "SP" lenses have zoom ratios
considerably smaller than that. But the 28-300 may be perfectly
adequate for modest size prints. I've never even seen one let alone
used one. For all I know it may outperform my two Tokinas.
