Yes, lots compared to the 5s.
sand_man's reference is exactly what I'm saying. Note that distortion does not only occur in one place.
You seem surprised.
I am. It seems to me that you are both talking about different things. I may be wrong though

We're talking about lens distortion which affects many lines, objects, shapes. Usually toward the sides.
But in different areas in the same picture, right?
:erm:

I would be lying if I said I could. There is simply too much going on in that image for me to make an accurate assessment.

Correct, different areas closer to the sides.
Maybe this pic will help.

Did I leave something out?
Rounding at the edges is the same thing as curvature.

Let me try make it a bit easier.
Do you see distortion on the rectangular object on the right? Do the proportions look correct to you?
They certainly do not, the bottom horizontal is much longer.

This seems a matter of perspective to me. It would be great if you cold provide us with the same shot taken with your 5S...

Im still not seeing excessive distortion, I just went and took the old lens test favourite, a brick wall. I would expect to see some distortion from a phone camera shooting a brick wall from around a meter away, neither is excessive, imo.
This is the 6s

These tests are not going to help.
They do show that the 5s renders more contrasty colours though, as I mentioned, which I like.

They would if they showed the excessive barrel distortion you are claiming...
Which neither do.

No they wouldn't, bricks are naturally skew.
Check your PM for the pic I sent to Spizz...
Note that it was tested with a 6 and 6s.

Bricks shouldn't be skew. Here's some insight into the brick wall test (with some examples, including barrel distortion).

I'm not interested in being told the bricks aren't skew when they are clearly skew. Your picture is completely different to those in the link.
Moving on. I await your reply to my PM in this thread.
It's taken with your phone Pot. There is clearly a problem with it as evidenced with the other pics you posted here.

No there isn't. It was tested with a 6.
Both yours and Dave123's have distortion (couldn't care less about the bricks test).
Once again, all lenses have distortion - smartphones, point and shoots, DSLRs, mirrorless... And the iPhone 6/6s has more of it than the 5s.
By the way, I'm talking to Dave123 now.

Yes, all lenses have distortion, it's what constitutes unacceptable distortion that counts. Your examples do look strange, but I can't duplicate the strange effect with a 5s, 6 or 6s. I have no real explanation as to why you got the result you did.
My 6s has similar distortion to my 5s, that's from testing, you can even see where spizz overlayed lines over the verticals in my building picture, there is very little barrel distortion.
