While the B-3 and B-4 enlargers were offered with condenser light source
only, the introduction of the Omegalite B cold light head required updates
to the B-Series enlargers to accommodate interchanging the lamphousings.
In the case of
the B-5, the upper bellows and tilting negative stage of the B-3 were
sacrificed, so the condenser lamphouse became the same as on the manual
focus B-6. However the condenser head was now offered with or without a
filter drawer. The carriage assembly and lifting lever system were also
slightly modified, but the column and autofocus mechanism remained the
same.
On the B-6, the
column was upgraded from the "lift and lock" elevation system of the B-4,
to the same crank operated system as the autofocus models, and the same
lamphouse lifting lever system as the B-5.
Customers were
now able to choose from an extended selection of accessories. The B-5 and
B-6 predated the Chromega colorheads, but since the lamphouse mounting
system was the same as the B-7/B-8, owners were able to retrofit the
Chromega B lamphouse.
Used Advice:
Check that the enlarger is in good working condition and complete with the autofocus tracks, lensmounts and negative carriers you need for the
formats you intend to print, since most parts and accessories for these
models have been discontinued for quite some time. |
