Has anyone problem with sigma 19 ????
When I take it to my hand and move my palm left -right I feel and hear how lens move . I took some shots sigma 19 + merlin and I see kind of strobe .
I’ve got both the 19mm 2.8 and 30mm 2.8 e-mount primes from Sigma – I used them on a recent successful corporate job along with the kit lens.
The worrying ‘something loose inside’ sound you hear is by design - the lenses are silent when mounted on the fS100 (or any other e-mount).
Although certainly not ‘L’ lenses those little pocket rockets can produce some acceptable images, the one touch auto focus also works well.
