try them at the same focal length at the same aperture and set it on a tripod shooting the same thing.

We should have a "readme" sticky... to teach how to test a new toys... I mean lens.

遲吓用18-55is kit lens 比一比..
我初步比好似 kit lens (f5@43mm, vs a16 f6.5 @31mm
both at 1/60 flush) 比清晰d

正有點想18-55is kit 同 A16 二選一

18-55is kit 平一倍多

buy it online... can't test it till it comes... so that's an disadvantage.

If you can test the copy first, it will be great.

it's not due to "out fo" the softness is due to the reason i mentioned above.

你睇清楚我寫咩先 "好似 outfo. 咁"

我知唔係outfo. , 但有冇走蕉我就唔敢品評啦
