and what might this be?<\/p><\/div>\n

Toronto<\/strong>. When the widely popular little Leica cameras first came out in the mid 1920s they were very utilitarian in design. To meet demand for features and versatility, Leitz made accessories. In many cases an accessory simply over-came an earlier design decision.<\/p>\n

A case in point is the very popular 5cm f\/3.5 Elmar lens. The aperture adjustment is a small tab on the front, around the lens. A lens hood, or especially a clamp-on filter, made aperture adjustment difficult to impossible.<\/p>\n

The solution was more accessories. In the case of a lens-camera combination a small ring, the VOOLA, was sold a decade after the end of WW2. This thin gadget fitted the hood or filter with the two stubs around the aperture tab. Loosening the thumb screw on the hood\/filter allows it to be turned and with it the VOOLA which uses the serrated arms to stay firmly fitted to the hood\/filter.<\/p>\n

Even without a hood\/filter attached, the tab could chip an unwary finger nail. And if the Elmar was used on an enlarger, its face down position made aperture adjustments almost impossible. The enlarger issue was solved by a couple of special accessory hoods<\/a> with the aperture adjustment ring built-in.<\/p>\n

NB: the photo of the VOOLA is courtesy of James Lager from his now rare late 1990s hard cover trilogy “Leica – An Illustrated History<\/a>” as I was unable to put my hands on my own VOOLA \u00a0(its around here somewhere).<\/p>\n","protected":false},"excerpt":{"rendered":"
