Seriously, there are much better lenses in the Pentax stable.
So far as standard lenses go, I can't think of any? The 645 75mm isn't all that sexy (good lens on a great format). The 43mm f1.9 and a50 f1.2 are top notch (and the k55 f1,8 isn't far behind), but the bokeh from the 105 beats the crap out of all of them. The 24mm 110 is very sweet, as is the 8.5mm Q standard prime. But I still don't think they match the 105. Don't get me wrong, Pentax has some fine glass, but I honestly do believe that the 105 f2.4 is the finest standard prime they have ever made. (I have lenses I consider to be better, but we're talking macro or telephoto lenses)
That t-shirt isn't my cup of tea, but I fully understand why it exists....
