The X1D is a medium format camera. For those who are not familiar with the term, it's related to the size of the sensor as there are different sensor sizes. There are very small ones like the ones of phones, there are 1inch sensors, there is the popular micro 4/3 that was adopted by Panasonic and Olympus with super fast auto-focus cameras, then there's the APSC, like the Sony A6000 cameras, Full Frame which is the standard and where you can get a real translation of focus-lens with no crop. For example, a 35mm lens has no crop with a Full Frame camera. There's a good article about this topic at DPReview they explain much better than I do.

The Hasselblad X1D has a bigger sensor than a Full Frame camera. That means, it captures a lot more light. The result is quite stupendous but it also has some downsides. The biggest one for me when using the X1D was that sometimes the camera was a bit too slow, creating some blurred images, especially if you are capturing a moving object. I was taking a bunch of photos of my son. However, the photos that were correctly taken were simply amazing.
