Two pictures from the harbor area in Oslo (Aker Brygge). One is taken with a Sigma 10-20mm and the other with the Sigma 4.5mm.
The fish-eye can create some cool effects, but there are several trade-offs. The 4.5mm use just 1/3 of the CMOS real-estate and it there is somewhat brutal process to unfold the picture from a circle to a square format. This could reduce the sharpness significantly. Below you see the results. Let me know what you think.

I like the top picture taken with the Sigma 10-20, not crazy about all the distortion caused by the 4.5mm fisheye.

I think the distortion in the 4.5 shot makes for a more interesting composition and result. The 10-20 shot just looks lopsided, to me.

I like the 10-20. The loss of detail and as you mention loss of sharpness is to noticeable with the 4.5.

The 10-20 shot is more cleaner and appealing to me. But,the 4.5 has a cool effect. I like them both,but if I had to print one,it's the 10-20 shot all the way.

Sorry. I come down on the side saying the fisheye loses something. I compared the two, and there are things I like about it, but the odd "distortion" just makes it look "not right". It almost feels painful to look at, because it doesn't look natural. What a beautiful area you have to shoot in!

The 4.5 really amps the foreground.
Could be an awesome effect with the right foreground.

Gotta agree here also with #1 . FEs' do have a good purpose for the right photograph but doesn't work with this one for me . MHO . I think part of it to me is with the FE i loose the ability to see that it's actually an HDR image .

I love the 4.5mm and how creative the photographer can get with it. Nice pictures.

Ditto for the first image. Actually I like both, but the first one pops more for me.
