Congratulations Mr. Owlett. Nobody here cannot but agree with you at
... 120-% ;-)

Rollei-TLR aficionados seriously consider switching to digital some
day but only when those technical and economical conditions will be
fulfilled

1/ the silicon sensor shall cover a true 56x56 mm image size and will
be housed in a Rollei TLR interchangeable back similar to special
R-TLR film back for cut film and glass plates. At that time Rollei
will be forced to re-introduce the interchangeable glass plate back no
longer available for the 2,8GX and FX !!
Of course, the number of pixels shall not be smaller than 30 million.

2/ The energy required to take and store one picture will be provided
by a single stroke of a Rollei winding crank coupled to a miniature
electrical generator similar to the one used in recent white-LED-based
pocket camping lamps you can find now in rounds-the-corner
supermakets; it will be considered acceptable if the crank has to be
winded about 10 turns forward, every 12 frames, in order to keep the
stored energy at a reasonable level.

3/ the price of the silicon image detector shall not exceed the sum
spent in 120 rollfims by a decent Rollei aficionado in 5 years.

THE infamous Rollei brochure : shame on it !

Fortunately this was corrected for the 2,8FX.

Yes. The diagram shows the 2.8-80 Schneider xenotar ; it was
fabricated first in the early fifties, after the 2.8-80 Biometar aus
Jena. The 2.8-80 planar followed soon. The 2,8-80 Zeiss TLR planar as
everybody knows is easily recognised to its front cemented doublet ;-)

Your xenotar is a late 6-element design. Why 6 and not 5 like in the
first 3.5-75 xenotars this is another good 'ol story for the
Rollei_list.

The honourable members of the rollei_list already have complained many
times about this. They even asked for advice to their favourite US
Rollei-Attorney. God Bless the Rollei_list ! Eventually their voices
were heard at the Salzdahlumer Straße. But it too a long time !

This was another wise decision. Grand children love Rolleiflex TLR
cameras but weware of small fingers approaching the twin front lens
elements ;-) bayonet-II UV protective filters are strongly recommended
in the presence of young childen. You cannot but let your grand
children operate all speeds of the Synchro Compur from the slowest to
the fastest ! And they should know by heart:

"- How do you recognise a Rolleiflex TLR ?
 - because it has two eyes " 

(Eine zwei-aügige Reflexkamera)

Good pictures with yout TLR !!
