DxOmark (CLick here) just published the full Pentax K-01 sensor test. The camera uses the same K-5 sensor which by the way is made by Sony. And the results are very good positioning the K-05 as second best mirrorless camera ever right behind the NEX-7. I really cannot fell in love with that camera design but I have been a Pentax K10 user for a long time and really like their usability and image quality. So I am not surprised to see a result like that.
The K-01 is in Stock status check via [shoplink ‘Pentax K-01’].
