Clearly, both cameras feature different resolutions and different sensor sizes. The K-30 having a tinier sensor is going to make achieving shallow depth of field more challenging and the Sony A9 II will deliver greater detail with its extra 8 Megapixels. Higher resolution can also make it easier to crop shots way more aggressively. The more aged K-30 is going to be behind in sensor technology.
