Hasselblad V APO super-telephoto at 500mm, conventional refractive design with apochromatic correction for 6x6.
The Hasselblad C Carl Zeiss Tele-Apotessar 500mm f/8 T* is the longest conventional refractive telephoto for the V-system, providing approximately 280mm equivalent on 6x6 medium format. This is a non-mirror design, distinguishing it from the C 500mm f/8 Tele-Tessar mirror lens listed separately.
The Tele-Apotessar design uses apochromatic correction for superior colour accuracy at this demanding focal length. The conventional refractive design provides smoother bokeh than mirror lens alternatives, and the T* coating ensures maximum contrast. The Compur leaf shutter provides flash sync.
Build quality is Hasselblad professional with substantial construction for the long telephoto focal length. The APO correction sets this apart from the mirror lens variant, providing technically superior images without the mirror lens's characteristic doughnut bokeh.
The C Tele-Apotessar 500mm f/8 is a rare and valuable V-system lens commanding premium prices. The APO correction and conventional optical design provide superior image quality over the mirror lens alternative, making it the definitive V-system super-telephoto for critical work.
