The 2.8 Rollei's got the reputation of being a collectors camera rather
than a user camera. A folly for rich people to buy and collect and
perhaps to sell on at a profit to a future collector. But nothing could
be further from the truth. The resolving power of the 2.8 Xenotar is
awesome and beats the 3.5 Planar hands down. If resolution is what you
are after then the 2.8 with the Xenotar is the one to go for. I know
that with wider aperture lenses sometimes a compromise is made with the
sharpness to get the wider aperture but this was not the case with that
lens. With a Tessar you are stretching it at f2.8 and perhaps an f3.5
would be sharper but not with the Planar and Xenotar design. But bear
in mind you are diffraction limited to 1500/f-stop lp/mm for yellow
light in any case so you wil only see a sharpness advantage at f5.6
I think Zeiss were rather miffed that the Xenotar 2.8 was better than
their Planar 2.8 and improved on it with the later f2.8 Biometar that
got put on the Praktisix/Pentacon 6/Pentacon 6TL. Somebody here will
confirm or otherwise. I have a few of them with the Biometar and the
lens is very sharp indeed. But whether you can translate that to film
depends on if you can get the film flat. I could use those cameras but
they are a bit bulky and have film winding and flatness problems so I
would trust a Rolleiflex more.
I'll try some of the shops here in Munich now I have almost given up on
ebay. Sometimes the pricing can be quite strange with cheap cameras
being dear and valuable cameras going cheaper than they should. I might
get lucky oneday.
>> Stay informed about: where have the Rolleiflex TLR 2.8E/F Xenotar's gone to?
