[QUOTE="Dodge DeBoulet, post: 80498, member: 14925"] "Reasonable" is a relative term. When you implement a digital zoom, you're effectively cropping the image in such a way that it frames the object you wish to present, then using a transformation algorithm that scales that frame to fill the target canvas size. That algorithm can be simple (pixel multiplication) or complex (vectorization), with results that are also dependent on image complexity, contrast and color depth. With the Spark, you're operating at a bit of a disadvantage from the get-go because it's photographic images are of middling resolution compared to modern DSLRs, and its video is an unremarkable 1080p/30. Like others have said, if you're intending to get professional quality results, you will likely need professional quality equipment. The Spark is an awesome piece of technology and quite suitable for casual photography and video, but it's not even at the "prosumer" level for image quality. [/QUOTE]
