As long as the projection is not the same as our eyes have naturally and our brain intepret, this will look un-natural, distorted.

yeah, and do you think that sitting a the place of the camera you would:
- have such restricted field of view ?
- you eyes will not see the plate as round

[cxdoo]

My impression is that any object spanning a significant portion of the frame will be distorted. If that's the goal it's very easy to achieve it.
Personally I find the distortion slightly nauseous.


1. Note the trees in mid to right background are level with horizon.





2. Well, this one is obvious.

Those are great photos, especially the second one.
However they don't look unnatural to me at all, so maybe it's not just about spanning the frame but also the distance from camera.

If you want more perspective distortion than you can get with your 10-20, the only option is the Sigma 8-16, or a fisheye.

And one with the DA15

Here are some samples from my late DA15ltd.

To me if you want a successfull photo with an UWA or a fish eyes you should not use it to put more in the photo but because you are after the distorsion effect and want to use it creatively. That's why the cars shoot of fs999 are great as well 2 portraits with the dogs of Sandy.

If you don't want the distorsion or you just want to put more in the frame because you are quite likely to get a photo that doesn't please you or that is quite boring.

In this case you may be better off with a moderate WA, let say in the 20-28mm range on APSC.

The architecture shoots you show us could be taken with a tele or at least with a normal lense and would avoid such extreme distorsion. They would likely look better if you are not after the effect and used the UWA just to get more in the frame... But this might mean you need to say be at the windows on the opposite building to be far enough from the subject. And that's not always feasible/easy.

Well put. If you look at the shots on the DA15 Ltd thread, the boring ones do just that. All the interesting ones exploit the huge DoF that you get with the ultra-wides.
