Here's a very helpful link about safe and unsafe lenses to adapt to ff cameras: https://www.panoramaplanet.de/comp/

Does anyone know whether mirror strikes are a problem with APSC bodies? Are mirror strikes a problem only on ff cameras?

Canon crop dslr are OK with Takumar 50/1.5. You can put some strips of woven duct tape on the face of the adapter (so about half a mil thick) to hold the lens off the body enough to stop the mirror catching on FF. Of course it means you can't quite get proper infinity focus though at smaller apertures it's passable. There are some great Takumars out there, and Pentax always make quirky focal lengths. Try the 120/2.8 if you can find one.

Thanks Sporgeon. I just ordered a Super Takumar 105mm f/2.8 ($80). May get the 120 another time. There are so many choices out there. Some sellers are obviously in love with their "rare" lenses. Just have to shop around. Doesn't look like anything much is rare. My goal is to keep each lens under $100. Also ordered an Industar 50mm f/3.5 ($18 including shipping from the Ukraine). The Russian lenses are especially interesting to me having grown up in the cold war. I like the novelty of USSR on the side of the lens.

Have fun! I like my old Mamiya-Sekor 55 f/1.4, has a different rendition, brings back memories. Also good for 6D are many Nikon AI and AI-S manual lenses. I enjoy using my dad's old 105 f/2.5 and tiny little 55 f/3.5 macro and my own eBay 50 f/1.2 AI-S lenses with adapter. You want a good Nikon F to EF adapter, not the el-cheapo.
