Sinar P & petzval Derogy

IN ENGLISH BELOW THE LINE

 

Fa pocs mesos vaig descobrir la modularitat de les càmeres Sinar de gran format, fabricades a Suissa des de 1986. És una meravella, encara més customitzable que la Hasselblad per al mitjà format.

 

A partir d'un rail base, així com dos estandarts (objectiu i portaplaques), hom pot adaptar aquesta càmera a multiples formats: 4x5, 5x7, 8x10. També es pot anar allargant el rail per fer servir optiques de llarga distancia focal, així com diverses optiques, dorsos, estandarts intermedis, manxes i fins i tot un magnific obturador central que permet l'us de lens "de barril", per arcaiques que siguin.

 

Aquest obturador Sinar-Copal de gran format és una meravella, permetent montar de manera senzilla multiples objectius sense obturador, com aquest petzval de bronze fabricat per Derogy a meitat del s. XIX.

 

Però la idea principal, es poder-ho fer servir com a base per a dorsos de ultra gran format fabricats en fusta expressament per al sistema Sinar.

 

=====================

 

A few months ago I discovered the modularity of the Sinar large format cameras, made in Switzerland since 1986. It's amazing, even more customizable than Hasselblad for medium format.

 

From a base rail, as well as two standards (objective and plate holder), this camera can be adapted to multiple formats: 4x5, 5x7, 8x10. The rail can also be lengthened to use long focal length optics, as well as various optics, backs, intermediate standards, bellows and even a magnificent central shutter that allows the use of "barrel" lenses, however archaic that be.

 

It's what I've done here, mounting a 150 years old brass petzval lens, made by Derogy. Thanks to the impressive large format Sinar-Copal leaf shutter, I can use this lens with film. The speeds of this shutter go from 1/60th to 8 seconds.

 

But the main idea is to be able to use it as a base for ultra-large format backs made of wood specifically for the Sinar system.
