What We Like
+Exceptional 50MP resolution with 30fps continuous shooting provides unmatched versatility for professional hybrid work
+Advanced AI-driven autofocus with 30% faster human eye detection and 50% faster animal eye tracking

Worth Knowing
−Premium price point ($6,499+) limits accessibility despite no resolution or burst rate increase over original A1
−At 30fps, lossless compressed RAW is limited to 20fps; must use lossy compression for highest burst rates
−Complex 64-page menu system with cryptic abbreviations lacks search function, requiring customization to My Menu
−Limited battery life (two batteries for full day) and CFexpress Type A card costs add to total ownership expenses
