Omega B-8
2¼"x3¼" Enlarger

Introduced: 1955
Discontinued: 1974

 

B-8/CXL Condenser Enlarger

The B-8 was the successor to the B-6 and B-4 models. The major change from the B-6 was to abandon the single triangular column in favour of the dual rail column like that of the D-2 and D-3,  which made it possible to offer the B-8 in both standard and XL versions.  

Like the updated D-2 introduced in the previous year, the new column featured a geared elevation control with the counterbalance spring mounted on the top of the column. The condenser head was the same double condenser design, with supplementary condensers available as accessories, as was used on the previous model. Initially the condenser lamphouse was offered with or without the filter drawer, but by the mid-1960s the filter drawer version became standard. The Omegalite head was also an early option, but it too was phased out by the mid-60s. Since the B-8 predated dichroic lamphouses, the only colorheads it was sold with were the non-dichroic Chromega B, Chromega B Halogen, and Super Chromega B, none of which covered the full 6x9 format.

By the time it was discontinued, the 6x9cm format had declined in popularity, and the model was not replaced.

Used Advice: The condenser enlargers are fully serviceable, but check which carriers and lensmounts come with the unit as these items can be relatively expensive.
