I found the same thing when I tried @jamesstaddon’s lenses (all pro grade L lenses) at a workshop! His lenses were nicer than mine, and so it was easier to get sharp images.
I’ve found that having better glass CAN—no, DOES—help. But great gear does nothing unless you know how to use it. And the best way to learn how to use a professional lens is to learn to maximize the one you have.
To get to the root of your particular problem, I’ve got a few more questions.
First, what specific lens do YOU have? (i.e. I think it’s a Canon EF-S 55-250 f/4-5.6 IS STM).
While great glass certainly plays a huge part in low light photography, there are ways to maximize what you’ve got.
So, third, what mode were you shooting in (Av, Tv, M, P, etc.)
What metering mode were you using?
And finally, were you shooting in RAW?
The last three things are—I’m finding—great ways to maximize your current gear without having to drain your savings account on an upgrade.
Let me know your answers!
