Originally posted by mmhhdmj I'm worried that the sensor is of lower ISO performance by one stop compared with K5, according to the samples from other sources.
The K5 has an expanded ISO range from 80 to 52600. Probably to differentiate models, I suspect that they dropped at least the 80 from the K-01 and K30. I would not be too concerned, and if you are - just purchase the K5.
There are slight trade offs here - The K-01 and K30 I suspect has focus peaking and the K5 since it is going end of life does not.
I would suspect that the K5 replacement would have all the bells and whistles. So, look at it this way - you have options!!
