Photographic Outfit 



As to tlie photographic outfit, it may perliaps be useful 

 if I desc'ril)e my own kit. wliich is now tlie result of about 

 ten years' experience. 



The lenses are the most important as well as tlie most 

 expensive items, several of them being necessary. First comes 

 the Tele-photo lens before mentioned. This is a difficult — in 

 fact, a very difficult — lens to work Avith : but it is an absolute 

 necessity for an ornithologist. INIine is tlie simple form, as 

 first brought out by the inventor, INlr. Dallmeyer, iioav, I 

 believe, not made, as it has been superseded by the later 

 form with a Portrait lens and a Negative lens attached to 

 the back. AVitli this lens the majority of the birds as 

 depicted in this volume have been photographed. Then I 

 use two Optimus lenses, a 11. R. of lO^-inch focus and a 

 Euryscope of Hh inch : with these two nearly all the nests 

 have been photographed. Irately 1 ha^e procured a Dall- 

 nieyer Stigmatic of 7-inch focus. This is a most useful 

 lens, and I wish I had had it sooner ; in confined situations a 

 short-focus lens is often a necessity, and in dozens of cases 



would have saved me much trouble and given a better result.
