sblutter Posted May 23, 2012 Share #1 Â Posted May 23, 2012 Advertisement (gone after registration) Not a camera issue: Â I've searched the literature and found nothing - a solution would be greatly appreciated. Â When pointed downward gravity pulls on the lens mount, throwing focus off (as with heavier zoom lenses. My current work-around is awkward - a spring clamp. Â Left side of bellows has 2 nobs - the larger focus one and a smaller one that after close examination appears to do nothing or is there for other accessories - anyone know what its for? Â Thnx!

duckrider Posted May 23, 2012 Share #2 Â Posted May 23, 2012 The smaller one is for fixing the slide copying compendium 16557 Q. http://pic01.auction2000.se/aukpic/lp/20100304_1524/19372_1.JPG Â kind regards Thomas Link to post Share on other sites More sharing options...
jaapv Posted May 23, 2012 Share #3 Â Posted May 23, 2012 There are two focussing wheels, one extends the bellows, the other moves the slide relative to the tripod mount. The small one, as mentioned above is for the Compendium. I wish one would appear on the market from time to time... Link to post Share on other sites More sharing options...

sblutter Posted May 23, 2012 Author Share #5 Â Posted May 23, 2012 Any suggestion for locking the focus nob - as in the case of shooting straight down? Â thanks Link to post Share on other sites More sharing options...
thighslapper Posted May 23, 2012 Share #6 Â Posted May 23, 2012 Stiffness of the track mechanism seems to vary ..... Â I bought a second set of bellows because of this very problem...... and the 2nd is stiff enough to resists creep with all the lenses I use. Â These must be an adjustment .... there will probably be a leaf spring somewhere in the ratchet that may either be tightenable or replacing. Â Doesn't look too difficult to dismantle and investigate if you're feeling brave...... Link to post Share on other sites More sharing options...
sblutter Posted May 23, 2012 Author Share #7  Posted May 23, 2012 Advertisement (gone after registration) I found and bought another. Will feel braver dismantling with a backup - I use this stuff in my art a real lot  Thanks Link to post Share on other sites More sharing options...
Washington Posted May 24, 2012 Share #8 Â Posted May 24, 2012 Seems to me it's a matter of tightening the knob and gear shaft. I haven't had this problem but there is a way to do it for sure. Link to post Share on other sites More sharing options...
sblutter Posted May 24, 2012 Author Share #9 Â Posted May 24, 2012 Nope. I took one apart - there is no adjustment available for tensioning the focus nob. It relies only on the friction of the tracks. I cleaned and regreased, no change. Â Work around: get focus really close, spring clamp the lens plane in place, fine tune with lockable lockable tripod mount nob & track. Â It works - but am disappointed no lock was designed in to begin with. They apparently didn't think anyone would need to take shots pointed steeply up or down Link to post Share on other sites More sharing options...
Washington Posted May 24, 2012 Share #10 Â Posted May 24, 2012 Use your imagination and add something like a fiber or nylon washer under the knob our somewhere to add friction to the turning assembly. Link to post Share on other sites More sharing options...
sblutter Posted May 25, 2012 Author Share #11 Â Posted May 25, 2012 I failed unscrewing the focusing nob... so far - good idea, thanks Link to post Share on other sites More sharing options...
