Awesome to see the GH3 images, many thanks.

You say the 12mm is sharper than the 12-35mm at 12.

How would you rate the 7-14 at 12mm or if you have access to a 9-18, how does that compare?

They are pretty similar at 12. There is more distortion on the 7-14 and the 12 has a wider aperture. However the results from the 12 are weak below F2.8. The 9-18 is great but it needs stopping down to F5.6 - F7.1 to get the best results, particularly in the corners (whereas the 12 would be fine at F4). I believe the 12 is rated the sharpest of the 3 at F4.

I have the 9-18 and really enjoy it. In the 35mm film days 24mm was my goto lens, so wondering if I should splash out on the 12mm f2

I know what you mean. I think it's an excellent lens, but be aware there is sample variation (make sure you can return it, just in case there is a problem) and that F2 is for low light only.

My other film days goto lens was the nikkor 135mm f2, so I guess the 75mm 1.8 olympus would be a similar look and feel?

I think that's right, but the 75 is a stunning lens, it might even be better...

How have you found the dynamic range of the images from the GH3?

Very good indeed, despite my cack-handed underexposure of the St Pauls picture. It is at least as good as the E-M5/E-PL5.

They say its improved but has it in real terms?

Oh yes....

The only down side of moving from my fuji S5pro to m4/3 has been the lack of DR

Here are the results from the E-PL5, which should be proximate (likely same sensor):

According to DXO, the S5 has better DR, but I would hazard a guess  that's because the S5 starts at ISO 100 whereas the E-PL5 starts at 200.

Thanks
