Although many books contain lists of lenses, these tend each to be a snapshot of a given period and none covers the whole history in the sort of detail a collector might wish. A collector needs to know about the minor products as well as the major ones and the most important developments. And the focal lengths and mountings are valuable information. Thus this list has been very much influenced by the experiences of lens collectors and purchasers. It is not and cannot be definitive in any way and must be used with caution. Initially it was compiled from the documents in Matt's files: later other items and information have been added by reading the older books and catalogues available. Items have also been added from the estates of the late J. Adams (the eminent lens worker) and R. Burnet of Maidstone. And most of the books in the Bibliography have played some part, mainly using sources published before about 1960. This date has been chosen as some sort of cut-off point for the list as it is aimed at collectors rather than users of new equipment, due to the vaste expansion in lens design which followed the increased computing power available after that date. Later items are included, but on a much more selective or perhaps random basis. But then it is probably still too soon to judge the long term interest of items as fresh as these.

There are several very impressive books showing what many camera look like, and these can be very valuable in showing how lenses were originally used. Some used in compiling the Vademecum are listed below. One point is that Indexing does not always list the lenses so that some examples of cameras fitted have been added to the Vademecum. Vial, Bernard, "Histoire des Appareils Francais" Period 1940-1960, Edited by Maeght, ISBN 2-86941-156-1, May 1991. J.-P. Francesch, M. Bovis, and J. Boucher, Edited Maeght, "Les Appareils Photographiques francais", Collection Photo-Cinema, 1993. (This has been coded as FBB in the text to save space.)P-H. van Hasbroeck, "150 Classic Cameras" Sotheby's Publications, London, 1989, ISBN 0 85667 363 3.
Much use as sources was made of the adverts. and text of the British Journal of Photography Almanack's (abbreviated to B.J.A.+year+ page) as available from 1900-1960. These are a unique long term history and almost all issues after 1900 have been consulted in some degree. The references may save a lot of searching through what are now rather delicate volumes with a high value. Note that Traill Taylor, one of the early editors,
had an especially deep interest in lenses and that lens related features were written in the issues for 1870, 1871, 1872, 1897 among other items. Also a run of Modern Photography from 1958- c.1980 was scanned as was the English Miniature Camera Magazine. It is worth mentioning that B.J.A. up to about 1956 had a regular list of books old and new worth reading including a section on 'Optics and Perspective' which is worth considering.
It is hoped to make more use in future of data bases from museum catalogues and collections, and permission has been obtained to use a unique source of data: this is the Auction Catalogues of Christie's of South Kensington, London. (Christie's, 85 Old Brompton Rd, London, SW17-3LD (Tel 0171 581 7611), where serial number data has accumulated for many rare lenses over the generation or so they have already auctioned photographic equipment. Numbers from this source have the last digit coded as a c to indicate the source.
However it is stressed that when possible the basis was original brochures and catalogues, either directly or in reproduced form, and that the drawings of lens layouts mainly have been based on them, all being redrawn for the sake of consistent style. These drawings are not exact, and are not suitable as a basis for lens making as some distortion resulted from the redrawing and in general the originals were made for publicity and recognition rather than to be exact for confidentiality reasons. This is also true of patents which are designed to illustrate a principle but do not have to disclose a fully working design. Some 1300 such drawings were made and a fair proportion were used. But even so, many lenses are only known to be of a generic type,and a group of the most common of these types are given as Q lenses at the beginning of the text. These may not be just like the lens in question, but should indicate the general type. Incidentally the list has been aimed at the needs of the reasonably well informed collector or dealer, rather than the lens designer at one extreme or the complete novice at the other. Hint: Locate the makers name from the list -or the lens- and open the appropriate file, and then use "find" by mousing the prismatic binoculars in the surtitles, and type in the lens name required.

U Ultimum V Variable X Xenagon Z Zeconar Compiler's Note: It has been a rare privilege to work on Matt Wilkinson's documents, and hopefully this Vademecum has made a fair use of them. Inevitably coverage of total lens production is still uneven since it reflects a collection which was still being formed. It is hoped that the coverage can be improved in future editions, errors be corrected, and that more experience will be gained in the use of the older lenses. The readers understanding is requested for the present. Incidentally it is the belief of the compiler that lens makers have consistently maintained a very high standard in their production, far more so than in other comparable industries. It seems likely that the majority of cases of so-called "bad lenses" are in fact due to attempts to use lenses in ways for which they were not intended or designed. Where there seems to be criticism in the text, it should be read with this comment in mind.
