More limited lineup from Tamron but actually a large percentage of all their Pentax mount lenses. More importantly Tamron has two key lenses - the 70-200 and 28-75. And the 28-300mm represents the only "walk around" zoom available right now. So there you have it. 'Focus-By-Wire' lenses (such as Canon's STM or Nikons AF-P) requires power to engage the manual focus rings on the lens, since manual lens mount adapters do not power the lens, those lenses will not be able to focus. Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode.
manual focus lens of course but that suits macro anyway. She absolutely loves it. She shoots in manual setting on the camera and uses the green button to meter. As for portrait lens, any of the 50mm lenses Pentax made for film are excellent. f1.7 M or A lens good balance of price and size. A- lens will talk to camera more than M-.
