Is it normal to have some distortion when viewing at certain angles?

Yes. The sides are curved refracting what you see but it's not abnormal and its a nice 360 view.

I had a little distortion with mine especially around seams but nothing too overwhelming.

It is normal. all land objects will appear like that. You should be good for looking at space objects.

I haven't noticed any distortion. Just shot several photos to recreate what you are seeing and they all look clear, with and without flash. If it started after you got the case, you may have a defective one?

You will need to find the sweet spot for straight lines (by tilting) in your composition. Sounds like your Sigma worked the same way. Fisheyes are like that :)

Yes, there is some vignetting as there is with many fish-eye or wide angle lenses. I think that it is the nature of things rather than a flaw.

Not extremely convex, but I think so just because of the range of view it displays.

...and the problem is? If you are noticing distortion then yes it is supposed to work that way and can be corrected during post processing.

Yes there is a distortion if the angle is greater than 45 degrees. And the audio is very very poor.

It's definitely noticeable from the sides and above. I'd say that it has about a 160 degree field of vision before you start to notice the picture getting washed with black. When's the last time you watched TV from an 80 degree angle? :)

this view angle is about 10 degree smaller than GC45. And picture quality is not so good as GC45.

I do not find any distortion at all. It's truly a good image. I am very happy with my purchase.

From what I learned doing research on this, the construction of the lens in the scope would normally cause distortions in colors unless corrected. It's a feature on better scopes. I've used this scope extensively and it's very clear and I have not seen any issue with accurate color.

No, you can watch from a distance or the side and it shows no distortion of color or picture. Not sure of the actual viewing angle.

I don't see any distortion, I use it for tying small flies for fly fishing.

The camera is easily tilted. I have not had any problems adjusting to the right angle for viewing.

Can see from different angles but not clearly. Still very happy with it. We bought two. Hope this helps

Distortion is more prominent in the camera-object distance. minimum distortion beyond 12 feet
