Review on 📷 Sigma 402963 16mm f/1.4 DC DN Contemporary Lens for Micro Four Thirds, Black - High-quality Wide-angle Lens for Micro Four Thirds Cameras by Ryan Frawley

You can't go wrong with this lens, it's a lot cheaper than Panasonic's 7mm to 14mm lens. Or Leica 8 to 16. The image quality is extremely sharp. Ideal for astrophotography. Like any faint light. Great street photography. Every picture I take is very sharp. Let in tons of light. The quality of the lens is impeccable. Protected from bad weather. My Panasonic g85 has no focus. Haven't used it on video yet, maybe in the future. This is a beautiful piece of glass. The focus ring in manual mode is smooth. This lens is an affordable alternative to fixed focal length lenses. One thing you learn with this lens is that it lets through so much light that a 15-stop ND filter is required. For long exposure during the day. Sometimes in very bright conditions I add 5 stops to get 20 stops. I use 100mm x 100mm square filters. The two or three shots I have are taken at sunset with no filter.
