Have a look at some images shot with the standard Pentax-M 50mm f1.7 then tell me if there's a Tamron which is sharper with the same focal length and compact size...

Looks like the OP had a good trip with a camera and lenses which take up very little space. If you liked the ME Super and want something longer to complete the outfit then look for the 75-150mm f4, it's similarly tiny for a lens of that focal length, weighs very little, takes 49mm filters and is very well-regarded.
