Pentax hasn't done much to update the box design of the K-5 II/IIs; the look is shared with that of its predecessor. Inside, you will find the usual accessories, in addition to a redesigned neck strap:
The new neck strap (middle) seems to have been inspired by others in the industry:
In the US, Pentax K-5 II is available as a body only, with an 18-55mm weather-resistant kit lens, or with an 18-135mm weather-resistant all-around lens. The latter gives you a bundle savings of approximately $179. The MSRP pricing is $1199, $1349, and $1549, respectively.
The K-5 IIs is solely available as a body only for $1299, which is bad news for those that wanted to save on the 18-135mm. On the other hand, the K-5 IIs should generally be used with better lenses (such as Pentax DA* or Limited lenses) if you want to take advantage of its higher-resolution sensor.
More information on these two lenses can be found in our Pentax lens database.
