The scenes were changing because of the wind.

The Pentax has a wider field of view.

The background blur of the Noname lens is stronger and smoother (may look boring).

The f/1.1 aperture definitely has more light transmission than the f/1.4 on the Pentax.

The Noname's f/1.4 aperture still has more light transmission than the Pentax's f/1.4 aperture, but noticeably increases contrast and reduces flare (compared to the f/1.1 aperture).
