Again the A350's default sharpening settings seem to be slightly lower than the Pentax's. However, the more expensive Pentax does appear to be putting more details out of the landscape painting on the Baileys bottle. The Sony also takes a less enthusiastic approach to saturation but this is easily tuned in both cameras. Again, in other respects, there's not a lot to choose between the two.
