Summary: The 14.6 megapixels Pentax K20D is amazingly fitted with nearly every feature possible for a DSLR camera: stabilization, dust-reduction, weatherproofing, advanced customization, digital white-balance preview, depth-of-field preview and live-view.
Pros: Excellent retention of details at all ISO, Quite accurate metering, Excellent focusing speed and accuracy, Fast and responsive, Built-in stabilization for all lenses, Durable weatherproof body, Innovative exposure modes & program line, Digital white balance preview, Extremely flexible image param...
Cons: Yellow color shift at ISO 3200 and 6400, Poor white-balance under artificial light, Image parameter increments too wide, Below average battery life, Sealed body means doors are harder to open
Conclusion: The Pentax K20D could be seen as a K10D Mk2, a camera that attempts to move on while putting right the minor flaws in its predecessor. And in that respect, it's a huge success. The K20D builds on the strengths of its forebear and corrects for the issue that plagued us most.
Pros: Excellent image quality at low ISO settings, Image quality still good as ISO 1600, Ergonomics up with the best of the best, Large and bright Pentaprism viewfinder (0.95x magnification), Robust body with dust and weather seals, high build quality, Accurate, reliable auto-focus, Sharpening modes gi...
Cons: Continuous shooting rate slow by modern standards, Hot pixels can occur and can't be automatically removed, Noise reduction cannot be raised as high as the competition, Live view mode adds very little to the camera (it is neither seamless nor able to usefully magnify), Autofocus not as fast or co...
Excerpt: You'd be forgiven for mistaking the brand-new 14.6 megapixel Pentax K20D (estimated street: $1,299) for its predecessor, the 10.2 megapixel Pentax K10D (current street: $700) at a quick first glance.
Excerpt: The 10.2MP Pentax K10D was a DSLR bargain in 2007 with its nearly pro body, excellent image quality, fast AF, image stabilization, and a price of only $920 (body only) when launched. It's still a steal at $700 (street).
Conclusion: Pentax K20D digital system camera I have put the bar quite high for the Pentax K20D. It should surpass the K10D, a camera that I like a lot. Luckily Pentax have not let me down. The best of the K10D has been preserved, and Pentax have added some nice extras.
Excerpt: The K20D ($1199,
body only) is the flagship model in Pentax's digital
SLR lineup. While it has the features of a midrange
SLR (most notably its 14.6 Megapixel sensor and weatherproof
body), the K20D costs several hundred dollars less
than the competition.
Pros: Very good photo quality, Good value for the money, Very well built, weatherproof body, Image stabilization system works with all Pentax lenses, Full manual controls, and then some, Unique sensitivity (Sv) and shutter/aperture priority (TAv) modes, Large buffer allows for lots of RAW shots in cont...
Cons: Consistently underexposes, A little noisy in low light, Live view lags behind the competition; LCD smaller as well, Below average battery life, Burst rate not as fast as other D-SLRs (even cheaper ones), Outdated, clunky user interface, Sensitive shutter release button (IMHO), Sluggish Photo Brow...
Conclusion: Other than the CMOS sensor it seems Pentax largely added improvements through firmware. In theory it is possible Pentax could have released a beefed up K10D firmware with many of these features but they have not, and it shouldn’t be expected that they will.
