Yes, the rumors were true: Hasselblad has been working on a world's first type of mirrorless camera. Today, the Swedish company officially took the wraps off of its X1D, a compact shooter with a massive 50-megapixel, medium-format CMOS sensor. That is the largest sensor we've seen on a mirrorless camera to date, opening up the category to a whole new class of enthusiasts. What's also impressive is how light the X1D is, weighing only 725 grams (roughly 1.5 lbs) without a lens attached.
