Our Flexible Focus Extension shafts can be shared between multiple enlargers by simply fitting an adapter knob to each of the enlargers. The flexible focus extension can then be attached or removed instantly. This adapter knob fits the fine focus shaft on the Micromega Dual Range Fine Focus accessory as fitted to Omega D-5, D-6, D-2, and Super Chromega E Dichroic enlargers. Adapter knobs for Omega enlargers without the Micromega attachment are also available - see "Related Products" below.
