An RF-coupled adapter that lets you mount the 40/2.5 from the Minilux

<p>You can extract the 40mm lens from the Minilux and mount it onto an M body in an RF-coupled housing:</p>

<p>Some Miniluxes are being sold on eBay as faulty, so you can pick those up for $150 or so. Get in quickly before the prices creep up.</p>

<p>Something like 400 Euro + customs + tax on the adaper though. Probably still a nice deal, but quite a bit of gambling involved. - I guess I'd rather buy some old used M lens.</p>

<p>I wonder if the focal length of the Minilux lenses is consistent enough for a "one size fits all" focusing mount to be accurate. Leica normally makes focusing mounts in 5 to 7 different focal lengths, to allow for variance between lenses.</p>

<p>Good point.<br /> This lens holder/mount, really should be for <strong>use on mirrorless</strong>, then all of these accuracy concerns become moot. <br /> <br /> Besides, if one needs this optic specifically <strong>for film use</strong>, then keep it in it's original "Minilux" body. <br /> For about $200USD, one can have the common EO2 error FPC replaced (after-market part).</p>

<p>Yawn. I would just buy the Voigtlander 35mm f/2.5 for $425 new or the 40mm Voigtlander f/1.4 Nokton for $500 and be done with it.</p>

<p>This is a 40mm lens so what frame lines on your M do you use? An external viewfinder will be needed as well.</p>

<p>I might add I have the Voigtlander 35mm f/2.5 Pancake II and it is a superb lens.</p>

<p>Why bother? You can get a mint 40mm Summicron for less than $500; one of the world's great lenses.</p>

<p>Or Rokkor 40mm/f2 even cheaper...</p>

<p>This looks like a reasonable product. The MS Optical conversion is more expensive and a more quirky barrel and aperture arrangement, whereas this one looks almost like a conventional Leica lens. Its a niche product that people wont buy as their first and only 40mm lens. Theres a ready supply of junk cameras to provide donor lenses. Its not going to sell in mass numbers but its priced to satisfy enough sales to warrant its manufacture. As a collector of 40mm lens I must admit I put my order in already. :-) <br /> Hint: Tell your other half "No this isnt another lens its just a spare part that allows you to salvage part of that old camera thats broken in the cupboard rather than throw the whole thing away and loose money. This is recycling I promise!"</p>
