shots that work better with fisheye effect
either due to greater coverage required, or distortion emphasis

Contrary to beliefs, it is possible to get a straight horizon with a fisheye lens (without defishing) if it is far away enough...
Not really true in practice. FE (and UWA) distorts more the closer the subject is to the lens and that includes straight horizontal lines at the centre of the frame. What's more, to minimise the distortion, the camera has got to be dead centre perpendicular to the horizontal lines.Er..... fisheye or not, your centre axis will always be straight. Distance is irrelevant.
woah, great shots nightmare and tomcat... very hard to decide since both creates nice pictures at certain times or another.
Hm.. seems like I will take the cheap Zenitar to start... and defish them if necessary... I'm seldom a serious landscaper anyway, though the perfect straight lines look good, I can live without for now... if I like a UWA next time, I'll just top it over. Afterall, its about the cheapest FE around, and I just want to cover range.
Got a deal today, hope the lens is a good one!
Thanks a lot for helping with the pictures!
Thanks.
Both the FE and UWA are actually niche lenses for adding that touch of drama to your images. However, getting either of them does not quarantee good pics all the time. You would need to learn when and where they could be used to their greatest effect. A lot of the time, people would say that it is very difficult to use these lenses and the lenses would sit in their dry cabinets most of the time or they would eventually sell them off.
Though I have both, I actually find the most use for the wide angle end of my full-frame 24-70mm for landscape shoots.
I suddenly wondered something, the human eye is considered wide angle right.

How come there are no distortion when the eye is looking at something? Why can't lens copy the human eye design. Is it because the "sensor" of our eye is concave, film and digital sensor are flat, thats why lens can't copy human eye design.

If the straight line is the horizon very far away at the centre axis, the camera is for all intents and purposes pointing perpendicularly to the horizon... hence the straight line at the horizon.
If the subject with horizontal lines is in the mid-distance or close to the camera, it could suffer distortion even if it is at the centre axis as most of the time it is not practical to be perpendicular to the subject because of space or compositional constraints. Even if the distortion at the centre axis is minimised, the rest of the subject slightly off-centre would still distort when shot with a FE, most of the time in a visually unesthetic manner. This would be where a UWA would be better off. Example...
This is not a keeper for me.

any shots to show?Anyway I just reviewed some of my test shots... the zenitar is pretty sharp stopped down... However, its not really fishy at all! All my pics look like they're taken with a UWA. =(
I like Fisheye Hemi.Anyway, anyone can recommend some de-fishing programs? I tried using the barrel correction in photoshop but it takes away the edges of my pictures.. hmm.

Coz i'm on a cropped body I guess.
