Owner reviews: Tele-Takumar 300 mm f/ 6.3
Build quality, sharpness even at open apeture of 6.3. Reletively light weight for the era and at 300 mm focal length.
With 12 blade apeture good boque opportunity, works great in AP (apeture priority) setting on camera.
Long throw focus ring, potential CA's if shooting near the direction of the sun, must use the long-deep sun visor.
I paid 22 dollars + shipping of 13.50 so about$36.00 invested making the value very good. Neat lens and fun to use with very good results with my APS-C DSLR.
