Just for a lark we tested my wife's 70-300CX (attached to her V1), and the HD DA55-300 (attached to her K-30), shooting at the moon tonight. The difference in IQ is minimal, but the K-30 + HD DA55-300 costs about as much as the Nikon lens alone!
The Pentax image is far harder cropped, but the Pentax camera's sensor has 16MP.
If we had used the V2 instead, the difference in available pixels had been smaller, and the end result more in favour of the Nikon, I guess?!
