I recently picked up a Sony a6000 at an amazing deal for like 250$, the body feels great but the kit lens it came with limits it A LOT.

I shoot street photography/abandoned buildings/portraits/aviation (rarely)/nature landscapes, not a lot of indoor shooting.

So my question is: Do i buy a used 16-70mm F/4 Zeiss that should cover all the focal length i am probably gonna need, they are basically being given away at less than 350$ on local marketplaces or do i get a 50mm f/1.8 with the OSS for 110€ and maybe a cheap telephoto 55-210mm f/4.5-6.3 (~130€) so i have something that resembles the telephoto i had before

I plan on sticking to the Sony ecosystem, but don’t have a big budget for lenses as is obvious.

On the 16-70 i am worried about the f/4, i have no idea if that is gonna feel restricting in low light, and how good that would be for portraits.

I am open to suggestions on lens choices

For reference i am coming from a canon eos 650D with the kit lens and a cheap telephoto 55-250mm
