JDMvW Posted July 7, 2013 Share Posted July 7, 2013 <p><strong>Some background first </strong><br />This is one of the those cameras that I have frequently referred to as basically unlikely to still work and impossible to find someone who can service.<br />The other day, I dug out this one to look at it in response to a post about unworkable cameras - a sort of Triste Camerique ( http://www.photo.net/classic-cameras-forum/00bmk2 )<br /><br />I looked at it again, and tried to figure out what was wrong with it. As it was, it was clearly impossible to load film into it without exposing it. So I puttered and finally figured out that there had to be shutter leaves in the lens assembly (this was a unique Pentacon SLR with a leaf shutter, back to that later). They were not visible, but I thought - it doesn't work anyway and am I not the Lord Naphtha, King of the Mild Solvents, Spirit of the Petroleum Wastes?<br /><br />So I splashed (actually, carefully) a little naphtha (aka, more expensively, as Ronsonol) into the area immediately behind the lens, proper, mount and worked the camera a little - <br />LO! The edge of the shutter blades popped out a little. A few more drops of solvent and suddenly the shutter popped into place, covered with dirt and solvent. I carefully wiped it off, worked it some more, and it started to close consistently after triggering the shutter (see below). I continued to work it, cleaning it as I went, and then left it to dry overnight.<br /><br />Is, is , it alive? (Mark Twain - Innocents Abroad).<br> <br />YES, IT'S <em><strong>ALIVE</strong></em>, BWA-HA-HA.<br /><br />So what follows is a report about the Pentina and how it is supposed to work (the match-needle metering is, of course, deader than a doornail unless somebody knows of a meter magic similar to naphtha for the mechanical parts)'<br /><br /><br /><br /><strong>Pentina </strong><br />first models 1961<br /><br /><br />When it arrived, I looked up some details about the model and the like on Dr. Mike Otto's fantastic (to a DDR-camera enthusiast) web page ( http://www.praktica-collector.de/ ).<br /><br />My model is the one shown at http://www.praktica-collector.de/114_Pentina.htm .<br /><br />But it was clear that no shutter was working, in the lens or out of it. So I accepted the widespread (as far as DDR cameras go) stories about repairmen fleeing in terror when they saw someone bringing in one of these. <br /><br /></p><div></div> Link to comment Share on other sites More sharing options...
