Thats a lot of $$$ for a lens that will not cover the new sensor sizes.
Not so...
(Info copied from previous thread on this subject)
The Hasselblad HCD lens line (28mm, 35-90mm zoom) has been designed to deliver outstanding lens performance (high resolution, low lens errors) on a Medium Format sensor area, in a lens design that is relative compact and light. In the process of optimizing design for all the performance criteria Hasselblad has carefully chosen its design elements with the following logic.
We have chosen a target sensor format of 36 * 49mm for the optimization of the lens performance for the HCD lens line in order to achieve a compact design with fast focusing as well as high performance. Top performance is reached even with sensors larger than 36 * 49mm. The only restriction is that a marginal crop is introduced with the HCD28 and the HCD35-90 in 35 mm setting. On a full frame 60 Mpix camera, the crop will result in an effective pixel count of 55 Mpix and a focal length factor of about 1.1. This means that the HCD28 will be equal to a 31 mm lens and the HCD35-90 will be equal to a 38-90 mm.
We have chosen to allow a level of basic optical imperfections (color aberration, distortion and vignetting) within the capability for our DAC lens corrections to handle it afterwards. We can therefore make a better design compromise and concentrate on minimizing optical errors that cannot be corrected by DAC, for example edge to edge sharpness. The results will not be as good for film use, which we therefore have excluded.
Our estimate on benefits with regards to size, weight and price are as follows: Compared to using the original full 645 film format (41.5 * 56mm) we are able to deliver a lens design that is around 30% more compact, and 30-40% less expensive.
To support the achievements of Hasselblad’s HCD lens design please compare the HCD28mm with other Medium Format lenses of the same focal length. Check the image detail and lens performance at the edges. Add to the comparison that all HC/HCD lenses include internal AF motor (fast, accurate focus), central lens shutter (flash sync at shutter speeds up to 1/800), and manual focus override. The difference in price between the HCD28 and the main competitor’s product is currently a 40% advantage for the HCD28.
