Focusing Aid

As featured in the August 2015 issue of LFI Magazine

U.S. company TAAB offer Leica-style lens focus tabs. After extensive beta testing, the tabs were launched on the market last month.

The majority of lenses in the M’s portfolio feature an integrated lens focus tab with a finger grip positioned on the lower half of the lens. However, there are still some exceptions – among them the Summicron-M 50mm f/2, the APO -Summicron-M 90mm f/2 Asph and the Noctilux-M 50mm f/0.95 Asph. The American start-up company TAAB now offer an innovative solution with their universally compatible focusing tabs. Mounting the lens tab requires a degree of patience, as the resilient Neoprene material offers little elasticity. Once attached, fine grooves on the interior surface prevent the ring from slipping out of place.

Almost appears to be part of the lens: the TAAB lens tab with convenient finger grip.

The result is a more ergonomic lens, with increased comfort during manual focusing. As an added advantage, the photographer is able to adjust the position of the tab around the circumference of the lens. While you may choose to attach it in the same position as on regular M lenses (on the lower part of the lens if the focus ring is set to 1.5 metres), alternative locations, such as the minimum focusing distance or infinity, are also available options. When mounted in the customary Leica position, the tab can be used to roughly select the focusing distance without looking through the viewfinder: set to the left, the tab corresponds to the closest focusing distance; when the tab is placed to the right, the focus is set to infinity.

TAAB lens tabs are matte black, and come in three sizes: ‘Mini’ (with a diameter of 44-57 mm) fits the Summicron-M50 mm f/2; ‘Standard’ (50-64 mm) is suitable for the APO Summicron-M 90mm f/2 Asph, while the Noctilux-M 50mm f/0.95 Asph requires the ‘Hefty sized TAAB with a diameter of 64-76 mm.
