Originally posted by LeDave Honestly, the on-board flash on the K-3 is useless (Some may disagree), I'd rather have the built-in GPS on the K-3ii any day and buy a separate flash such as the 360 or 540.
Sure the K-3ii has better AF, but it's not substantial enough to be a deal breaker.
Actually, many of us would disagree because the K-3 flash broke new ground that was particularly useful for multi-flash photography, especially when working around the limits of pTTL, and for emergency fill-in needs when unexpected shadows interfere with important moments (rare but essential when needed).
I'm yet to find a situation when GPS would have improved a photograph, but it is a matter of personal preferences. What has been evident is that the K-3ii became much more deeply discounted sooner than the K-3 and given the pricing trend-line we might see the K-3ii priced the same or slightly less than the K-3 used after these models are retired.
