A few points from the interview:
- All other things being equal you can potentially decrease the size of a lens by 20-30 percent when going from Full Frame to APS-C and about 30-40 percent when moving to micro 4/3 – but this really depends on the type of lens.
- The point of developing the new Carl Zeiss 55mm f/1.4 is to bring unprecedented performance in open apertures. The lens design is actually made of a combination of two different lenses and is a new, first of its kind for a 50mm lens.
- The new 82mm front element was designed to produce sharpness across the entire frame.
- Don't expect any AF capable lenses from Zeiss in the foreseeable future for Canon/Nikon.
- Zeiss can add a stabilizer to manual focus lenses but this will degrade the optical quality of the lens to a degree (it will require some freedom of movement from the optical elements) and so not something Zeiss plans to do anytime soon.
- Zeiss highly recommends that you use a focusing screen when using a MF lenses – this is because the conventional focusing screen of digital cameras isn't ideal for manual focus (we can surly attest to that).
- Our final question had to do with a hypothetical size of a 50-100mm f/2 lens compared to the more conventional 70-200mm f/2.8. The answer – we are looking into a heavier and larger design and not something most people would like to carry or pay for…
