5cm F1.5 Carl Zeiss Jena Sonnar, converted to Leica Mount
$430 within US, $460 International
For sale is a 1937 Carl Zeiss Jena Sonnar 5cm F1.5 (uncoated optics) custom converted to Leica Thread Mount using a Jupiter-3 focus mount. Glass is near perfect, nice bloom on the front and rear surfaces, some bubbles, normal for this vintage. Optimized for wide-open and close-up use, tested on the M Monochrom. It focuses best at infinity stopped down to F2, out to ~100ft wide-open at F1.5. I built this one using an Uncoated pre-war optic from a Contax mount lens and a 1973 ZOMZ chrome focus mount. Focus is well-damped and very smooth, I replaced one of the guide pins of the focus mount with a larger one- which eliminated a light play in the focus. I disassembled, cleaned, and relubed the focus mount and the optics module. Took out the front element and rear triplet, and cleaned all of the optical surfaces. I flood cleaned the aperture blades from the rear, got most of the oil off the blades, removed the old grease under the aperture ring and used a dab of vacuum pump grease to dampen the movement. The retaining ring of the middle triplet was in tight, and what little oil on the blades is not worth the risk of damage.
Cosmetically the aluminum mount is in 8.5/10 condition, marks in the aluminum as shown. Plastic front and rear caps included.
