My First "Mosaic" Digital Medium Format Image
D igital image sensors are manufactured in many sizes ranging from smaller than a pencil eraser to the approximate size of a playing card. The larger the sensor size, the better the overall image quality so photographers tend to want the largest size they can afford. Naturally, the larger the sensor, the higher the cost so that is usually the limiting factor for photographers. Also worth considering is the price of lenses. The larger the sensor, the larger the lens needs to be. Tiny sensors only need tiny lenses (think cellphones). A sensor the size of a playing card requires a big lens and the larger the lens, the higher the price, generally speaking (quality is a huge factor too). Each time a photographer moves to a larger sized sensor, the price of equipment jumps significantly. The same has always held true for film too. The smaller format of 110 film (same size as 4/3 inch sensors) costs less than the larger 35mm fil...
