You expressed a ton of interest when we published our series of Pentax K-3 First Shots for pixel peeping last week, so we moved quickly to provide you with our initial Pentax K-3 image quality analysis. For this analysis, we've compared test images taken with the Pentax K-3 side-by-side against five likely top competitors -- the Pentax K-5 II, Canon 70D, Nikon D7100, Olympus E-M1 and Sony A77 -- at a range of ISOs.
The 24.3-megapixel Pentax K-3 packs 50% more pixels into its APS-C sized image sensor than the K-5 II, increasing linear resolution by almost a quarter. And thanks to a new PRIME III image processor, it simultaneously increases performance to a whopping 8.3 frames per second at full resolution, for as many as 60 JPEG or 23 RAW frames. And despite the significant resolution increase, the K-3 still offers a maximum sensitivity of ISO 51,200 equivalent.
But how do the new DSLR's photos fare? Is the K-3 a big step up from the K-5 II? And does the camera handle high ISOs well?
Find out by reading our Pentax K-3 image quality comparisons here! And below that, you'll find our print quality analysis, where we discovered the K-3 produced a terrific 30 x 40 inch print at ISO 100/200.
