A Calumet Netherlands Leaf specialists gives me a demo of the upcoming Leaf AFi-II 10. This camera is the evolutionary next step following the Leaf AFi which is based on the Franke & Heidecke chassis evolved from the Rollei 6008AF and uses the same lens mount. I spoke to many people at the leaf booth including Ari Briggs, Executive Director of Sales and Marketing and Seth Greenberg, Director of Marketing for Leaf. These people presented some insight on some of the nuances of the camera and little quirks which are spun differently for marketing.
While the AFi/AFi-II/Sinar Hy6/Rolleiflex Hy6 are marketed to support all of the old lenses of the Rollei 6000 series, some of the people at the Leaf booth noted that these lenses aren't tuned for digital sensors which have lower tolerances for variances and some of the older system lenses may not perform as well as the newer versions of the same lenses which have been optimized. However, another representative who has both the Rollei 6008AF and the new Leaf AFi noted that between one of the new lenses and a good sample of one of the old lenses, a shooter may not be able to see a difference in his prints until he or she views them both side by side.
The margin for error in tuning of these systems is very small. During the demo, I witnessed how even switching between identical digital back models from one body to another could completely throw out the focusing from one body to another. It isn't that the bodies are fragile but it's because the back and body are tuned together out of the factory so that the body holds the back and the lens so that the lens very precisely casts light from the lens and focuses on the sensor but these tunings will be different on different bodies.
It is also interesting to note that many of the lenses that are available for the AFi/Hy6/6008 system are available at wider relative apertures with faster shutters and are designed with 6x6 format coverage whereas the lenses of systems like the Hasselblad H or the Mamiya/Phase One digital platform are available with narrower relative apertures and, especially in the case of the current Mamiya system, have much slower flash sync but have a focal plane shutter. While the wider relative aperture is optically and creatively very attractive, it's important to note that lens of similar focal length in the Rollei/Leaf/Sinar system are SIGNIFICANTLY heavier than those of the Mamiya 645 or Hasselblad H system. For a medium format system, weight isn't my first consideration when purchasing but for our smaller friends, the weight of some of this glass is so great that it may become prohibitive.
After viewing the Hasselblad booth I think that the Leaf AFi-II is still on the top of my list for what will be replacing my Rollei 6008AF/Phase One digital medium format system.
