I've been using panasonic since till today and all i can tell is THEY CAN'T MAKE A GOOD CAMERA. I've been observing how panasonic evolves and had hopes that even though they're pretty new to the Full Frame, that they'll improve it's l mount system year to year, but they didnt. First they released s5mkii and i was bittersweet about it, then g9ii and i was frustrated, i told myself that it'll get better... But then they released s9 and i became mad. Pajeets at panasonic absolutely dropped the ball and burrowed their l mount under dirt and shit. EVEN SONY is tenfold better than anything that panasonic produced. Absolute garbage and waste of momey. I sold my s5mkii and all the l mount lenses and went sony, YES SONY, and despite what you might think I made a good decision. I tested plenty of full frame cameras from canon, sony, nikon and I'm pleased with fx3 and e mount. Idgaf about pancakes so it's perfect for stuff i do. Not saying canon or nikon are bad, just not for my needs. As for panasonic, im never touching that shit again. Plenty of panashills gonna sethee, but they're just trying to push their turds onto others to make them miserable as they are. Im moving on and definetly for better. It's not quirkyness, It's just that bad.
