While the range is useful, it is still just an F8 equivalent lens.

That's an interesting comment. I don't see a full frame camera amongst your listed gear so I'm wondering what the f8 is equivalent to.

I have the 7-14mm f4 and and have never had an issue with subject isolation or a problem with low light exposures.

The f8 is only for DoF. Light gathering is stil f4. The 12-100 f4 operates the same way.

f8 is only correct for full frame.

Here, let me help with some other dof equivalents

1.7" f1.8

1" f3.0

aps-c f5.3

645D f10

6x6 f14
