As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! I have been cleaning out some old lenses- and selling them off- and one has caught my eye and got me wondering. Could I mount this 3 Inch Ross Xpres lens on a Leica body? If I did what focal length would it be? I don't even know what type of camera the lens is native to - I could find no other just like it- I assume it is a large format camera? Then I saw on ebay these Ross to Leica lens conversions. Wow: pricey! Is there any reason such a lens may be desirable? At that kind of price? And if I wanted to get my own Ross converted- and hints on who might do such work and what it might cost? Please convince me not to sell this lens and to have it converted!

jaapv Posted November 11, 2015 Share #3 Posted November 11, 2015 Some Ross lenses were made in LTM mount. In that case the conversion should be easy through a standard LTM adapter, provided the register distance is correct. I suppose the ridiculous price on the Internet is because of an addition of a RF cam (and even then... ) which is not needed for the 240. Link to post Share on other sites More sharing options...
Orient XI Posted November 11, 2015 Share #4 Posted November 11, 2015 The focal length would be 76.2mm. To be worthwhile it would have to perform much better than a Ross Xpres enlarging lens I owned in the 1950's. Link to post Share on other sites More sharing options...
pgk Posted November 11, 2015 Share #5 Posted November 11, 2015 I used to have a Ross lens in a 'home made' conversion to LTM. It worked fairly well but the lens itself was no great performer so it wasn't really worth the effort of building it - I suspected that a model engineer had made the conversion which was workmanlike rather than elegant (and perhaps built at a time when buying an equivalent Leica lens would have been unaffordable. I'm not sure that yours is a lens that I would bother using on a modern digital camera myself - 3" f/3.5 isn't really a high enough specification to make it worth while IMO.
