The 7 Artisans 10mm F2.8 lens offers good sharpness at F5.6, being compact and lightweight, priced at $199. However, it has subpar autofocus, long minimum focusing distance, weak flare resistance, and average corner sharpness. For better options, consider the Viltrox 9mm F2.8, also priced at $199, which excels across more performance metrics.
