In short, is an better than an for theman who has the money to buy an anastigmat but not the in-clination to make himself master of it. I have the majorityand not the minority of kodakers in mind. The use of lenses on vest-pocket cameras has notcaused the amateur any great amount of trouble. The aver-age focal length of these lenses is about 33^ inches. Sincethis is quite a short focus, the large working-aperture of thelens does not affect materially the depth and detail of the re-sulting negatives. Moreover, focusing with these short- lenses is comparatively simple, and it requires no specialstudy. Hence, as far as vest-pocket and miniature cameras 54. Co hi ^ > w So S o ^ O 5s 55 are concerned, an lens may be used as successfully as anF/8 rapid rectilinear. However, the case is radically different when the amateurconsiders equipping his Sj4 x 4%, 3^ x 5>4, 4 x 5 or 5 x 7camera with an anastigmat. Even if he purchases an ,there is, nevertheless, a marked difference between it and hisold F/8 rapid rectilinear. If he decides upon an , hischances of success are reduced to a minimum temporarily, ifnot permanently. It is true, optically, that an l^^sstopped down to F/8 will give the same depth as an F/8 lensof the same focus. Unfortunately, the unthinking amateurwill persist in using his ^^^^ wide open on any and alloccasions. The inevitable result is lack of depth, over-ex-posure or an unprintable negative which is heir to all the photo-graphic faults in the calendar. All this leads the averagecamerist to say things to himself that are far from compli-mentary to the
