That depends on who is managing the warranty and design.
to increase warranty period is usually a cost driver because the liability exists longer, and you are potentially also exposed to what I would call latent defects which take several years to develop, and where a normal warranty would not be hit with these costs.
Therefore, where does the money come from? A good company will look at failures and redesign things, or for new lenses design them to remove minor failure modes thereby reducing the warranty cost. A poor company will make up the provisions by cutting manufacturing costs somewhere, which can lead to lower quality.
The real question is, what type of company is pentax?
