Paul - I quite liked the fish eye distortion in #3 so it has only had a small fish eye reduction. I agree this isn't to everyone's taste since it is VERY unnatural. I was expecting #2 would arouse the more negative comments

DOF in last image - only shot at F4 so it's lighting more than anything else
Geoff - thanks. I bought the 10.5 as an effects lens, but I've found that using it + DxO optics to defish it's more versatile than that
Craig - #1 is my favourite of all the cathedral shots. I spent some time framing that before I took the shot and I think it shows. It was shot at 640 ISO which helped bring up the foreground. I did a bit of dodging in
PS to bring up the interior a touch more and a layered brightness reduction on the exterior. Shows just how capable the D70 is. #2 is the first shot I've done where I haven't defished at all since I liked the effect (BTW I've updated the post at the top to show % defish for each image). If you like stained glass then this place is a must - it's everywhere.
Chris - thanks. The 10.5 is certainly sharper, but my hand holding isn't superb either so some of the apparent softness of the 12-24 may be due to the longer exposures in the low light (to guard against this a bit I shot all of these at ISO 640)
Matt - I almost didn't post the round stained glass window since it was MAJORLY photoshopped to bring up the area around the glass. In the original all was black excpet for the window. I think I failed. Re: #1 - as said already it's my fave. I just love the light in this one and it's beautiful simplicity.
For those who commented on #3 the fully defished version with a slight crop is below:
