<p>takumar lenses are special. i have never used super takumar 50. but, i am partial to my s-m-c-takumar 50/1.4 lens. i also like s-m-c-takumar 85/1.8. in 2011, my house was burglarized and i lost nearly all my photographic equipment except for 35mm film cameras (lx, spotmatic, mx). so, i was wondering what to do. i felt i had a clean slate. but, i missed takumar lenses. so, i decided if i could find another s-m-c- takumar 85/1.8 and 50/1.4, i would get them. so, luckily, i did. after that i added cameras to go with them. i bought "a"50/1.4 also. i like it really well. i like manual lenses. i like the feel of manual focusing. "fa" lenses do not give me the same feel, however. when i use fa lenses i tend to use auto focus. i have several takumar lenses and they are pleasant to use. </p>
