initially designs for Ukrainian/Russian MF cameras which Hartblei
found another use for. Their images circles allows them to cover the
35mm format with extensive movements. Hartblei's innovation was to
make a workable flexible mount. The lenses were variable in quality,
but some were apparently quite excellent.
Shift and tilt-and-shift lenses for 35mm all are essentially 'Medium
Format' lenses; otherwise they wouldn't work. The lenses and optical
designs don't care whether the image they produce gets imaged onto
35mm format, 4/3 format or 6x6 format. While it's true that it's
harder producing a lens that covers a larger format with the same
performance as one for a smaller format, it doesn't mean that the
lenses with larger image circles are always worse. The 35mm TS Canon
I have is an outstanding lens by any measure and it certainly covers
6x6. The 24TSE that Canon just discontinued is a relatively poor lens
and would be seen as such on 6x6 just as it is on 35mm. The
introductory information on the new 17 and 24mm Canon TSE's gives me
high hopes for excellent performance. The new Zeiss/Harblei lenses
are rather uninteresting to me, as were the earlier Hartblei lenses
because of their longer focal lengths, but at the Zeiss prices they
had better be rather special compared with the 45 and 85/90mm focal
lengths of the Canon and Nikon equivalents. The ease of switching
axes for the shift/tilt isn't such a big deal under most
circumstances once you have your main workflow set.
