covered box. They are very light and portable, 

 and can be easily fitted with any lens it may be 

 desirable, to use. A finder is generally attached to 

 the base-board, and is made to reverse, so that the 

 picture can be taken either vertical or horizontal. 

 The camera shown in the illu.stration is fitted with 

 & Bausch and Lomb shutter. It has a focussing

scale for hand use, and a focussing-screen when 

 the camera is upon a tripod. Messrs. Lizars, of 

 'Glasgow, make a neat folding hand camera, some- 

 what of this type, to which they will fit any lens 

 or shutter ; it can also be arranged with either 

 dark slides, changing-box, or roll-holder for rollable 

 films and day-light changing. These cameras, 

 fitted with rapid rectilinear lens, range in price 

 from five pounds upwards according to lens and 

 size. The iiame of this camera is the '-• Challenge." 

 It is made in quarter-plate, five by four, and half- 

 plate ; also in stereoscopic size. 



The following details of the Model C are applic- 

 able to all the difi'erent patterns of cameras turned 

 •out by this firm. The camera is made in finest 

 Spanish mahogany, either jjolished or covered in 

 morocco leather, leather bellows, and focussing- 

 hood. The shutter is the Bausch & Lomb, works 

 time or instantaneous up to the hundredth part of 

 a second ; being all metal, extreme climatic changes 

 have no efEect upon it. The finder is the latest 

 improvement of the New Brilliant form, giving 

 exactly the same view as that shown by the lens, 

 and reversible for either horizontal or vertical 

 pictures. All the lenses supplied with these 

 cameras are carefully selected and tested before 

 being sent out, each being fitted with Iris dia- 

 phragm. 



Bi Another folding camera of somewhat similar 

 type is the " Optimus " Kopit, made by Messrs. 



"Optimus" Koi^iT Hanij Camera.

Perken, Son & Co., of Hatton Garden, London. 

 This camera is of such small size that it may be 



readily carried in the pocket. When in use it can 

 be held in the hand, or it can be attached with 

 screw to tripod for either horizontal or vertical 

 pictures. Among the many advantages it posses.ses 

 are the following: — rack and pinion focussing 

 adjustment ; rising and falling front ; swing back ; 

 roller blind, time and instantaneous shutter; 

 automatic hood attached to ground glass, ren- 

 dering focus-cloth unnecessary; three double 

 dark slides ; best workmanship throughout ; well- 

 seasoned, highl}' polished mahogany, or mahogany 

 covered with black leather of durable quality. The 

 square pattern, with reversing frame, is £6, and 

 the oblong pattern £5. 



Messrs. Butcher & Son, of Blackheath, S.E., also 

 make a camera of this type^ the price of which 

 varies from £1 Is. to £4 10s., according to lens

and finish. We would, however, draw special 

 attention to the pocket and folding cameras 

 manufactured by Messrs. Shew & Co., of Newman 

 Street, Oxford Street, W., the makers of the 

 celebrated Xit camera, which is, we think, the

neatest, simplest, and smallest pocket-camera ever 

 put on the market for plates. AH cameras by this 

 firm are Jjeautifully made and finished, and for a 

 small pocket-camera the new convertible Xit is 

 all that can be desired. It can be fitted with 

 any finder, lens, or shutter the purchaser may 

 desire, and also with dark slides or changing-box. 

 The Xit cameras are made exceedingly light in 

 weight, and are very portable. They are easily 

 adaptable for lenses of varying foci, and the Con- 

 vertible Xit camera, fitted with the Zeiss Con- 

 vertible Anastigmat lens, of either two foci or 

 three foci, forms one of the most complete and 

 all-round useful pocket-cameras that we have met 

 with in our experience.
