Any lower-priced fixed aperture Sony E-mount zoom lenses? (under $500 US)?

I'm noticing that the Sony e-mount lens system is very limited. I did notice there are some fixed aperture lenses that range from 800 to $1000.

I understand fixed aperture lenses are generally more expensive anyway. But just to make sure, I'm not overlooking anything here, correct?

Sigma and Tamron appear to make great lenses for the Sony A mount, but without buying an adapter for the E mount, it won't communicate with the body. I generally use manual lenses anyway. However, I'm considering the Sony A6000, which has fast autofocus, but the only zoom lenses that look native are f4.5-6.3

Am I missing something? Is this just the climate that we're in now where the lenses arent as robust as the Canon and Nikon lineups?

Your understanding is correct
Fixed aperture zoom lenses are much more expensive than the normal variable aperture zoom lenses
