Hi!
I’m a Sony a6100s user and I need a help with choosing my next lens. Currently I rock my Sigma 30mm for APS-C, but I came to the conclusion that I need a quality zoom lens for different purposes - product, event, concert photography etc. Whereas Im going to upgrade to Sony a7iii or a7iv in the near future (let’s say about March) I was considering Tamron 28-75, because I could use it on my current APS-C camera as well as on the future Full frame.

Nevertheless Im torn between choosing the upper option or picking up some 18-105 f/4 designed for my current sensor and then selling it with my a6100, but Im not sure if its reasonable to buy a lens only for couple months.

Maybe I’d better invest in other zoom lens? My budget is up to 1000$.

Any help is welcome. Cheers!
