No, looks not right to me. Though I don't have this particular lens.
But can't you try to click through the aperture to see it has WO and minimal Aperture and also check exposure by each click?(though there will not be exact 1EV difference due to design and vignette, but at least you can see if it is obviously wrong?)
Why not? There are plenty of lenses that does not open the aperture fully at the largest f-stop. The 15/4.5 does not and it's well known. Probably because it would have rendered an unsharp image and/or terrible vignetting.
Thanks a lot everyone. Glad to hear it's as it should. Hadn't seen this type of design before, so was surprised by it. Granted, I've probably not owned as many lenses as most of you, at least not as Makten.
It's easy, start by going somewhere that has a good vantage point or interesting subject, and emulate what's in the pano thread, you can't go wrong.
Sunrise's and sunset's are a safe bet too.
If you've never shot wide before, take just the one lens and don't stop at just one picture of a subject, get to know it, and cruising around in live view makes finding great compositions a breeze, and fun.
