Which is better, spittoon or 18- 150?

1, better picture quality: as a fixed-focus lens, the small spittoon has better optical performance and can provide better picture quality, while 18 bar 150 has a large zoom range, which leads to the decline of picture quality, so it is not as good as a fixed-focus lens.

2. Background blur: The background blur effect of small spittoon is good, which can better highlight the main body and create a dreamy atmosphere, while 18 bar 150 focal length covers a wide range and needs more photographic skills to control.
