Small size with wide zoom range
Cheaper than Sony 18200LE
Tamron offer 5 years warranty compare with 1 year Sony
Not very sharp in telephoto end
Small Aperture, not good at night
Really cheap, I bought it second hand for 2xxx and it come with long warranty.
The design is identical to Sony 18200LE, even Sony one is OEM by Tamron.
I use on A6300, it fully support PDAF autofocus system. As I search from internet, some old version of this lens do not support PDAF autofocus, and you cannot upgrade yourself, so please check before you buy.
As its small aperture, it is very good and fast in day time but not at night. However, there is no large aperture zoom lens for APSC E mount.
