👎 Cons

The 10-17mm focal range is relatively specialized and may not serve as a general-purpose zoom lens.
While it has a Super-Protective coating, it's not explicitly stated as fully weather-sealed or waterproof.
No information is provided regarding optical image stabilization, which could be a consideration for handheld shooting.
The image circle is matched to CCD sensors, which might not be fully optimized for newer Pentax DSLRs using CMOS sensors if the design hasn't been updated.
The metal mount, while durable, can add to the overall weight of the lens compared to plastic alternatives.
