I'm new to more advanced photography so please be patient! I just purchased a new lens - the h-fsa45200 (Panasonic Lumix G Vario 45-200mm) for my Panasonic Lumix GX80 (GX85 in USA). However, when using it for the first time it seems hugely overexposed: very little colour, everything very white. This is in automatic and more manual settings. I have tried adjusting the aperture, ISO (as I was playing with these the last time I used the camera), and white balance, but this doesn't make any difference. I tried the minimum and maximum for both iso and aperture, but it's still very light.
The kit lens works fine and the contacts look fine, as far as I can tell.
Does anyone know if there is something I can try or could this be a fault? Any suggestions will be gratefully received!
