andybarton Posted February 14, 2015 Share #1 Posted February 14, 2015 Advertisement (gone after registration) Now, I am not a collector, but I do have two 12585 lens hoods. Lucky me. One of them is an12585H. But, they look identical. They are engraved exactly the same, including the 1:2/35 engraving and they both unscrew to take a Series 7 filter, like the 12504 that I use on my 35 ASPH does. I have read that the only difference is the thickness of the metal used in the hood itself, but to be honest, I can't see any difference. Thanks!

sblutter Posted February 14, 2015 Share #2 Posted February 14, 2015 Plastic vs metal? There was a discussion on this some time ago - try the search tool 1 Link to post Share on other sites More sharing options...
andybarton Posted February 14, 2015 Author Share #3 Posted February 14, 2015 They are both all metal. I have done a search (the first thing I did), but I couldn't find anything relevant. Link to post Share on other sites More sharing options...
luigi bertolotti Posted February 14, 2015 Share #4 Posted February 14, 2015 (edited) Frankly, I think that simply your 12585 is more recent then the other, from a time when they had abandoned the letter at the end of the code, being it no more useful...

pico Posted February 14, 2015 Share #10 Posted February 14, 2015 The 12585 unscrews? I wish mine did. I'm afraid it won't budge. I'm afraid I will break or bend it if I try any harder. Link to post Share on other sites More sharing options...

pgk Posted February 14, 2015 Share #14 Posted February 14, 2015 ..... they both unscrew to take a Series 7 filter, like the 12504 that I use on my 35 ASPH does...... Are you sure that they are designed to unscrew and that they actually do take a Series 7 filter Andy? I've had several 12585s over the years but cannot remember them ever unscrewing (I may still have one - I'll check it). Link to post Share on other sites More sharing options...
andybarton Posted February 14, 2015 Author Share #15 Posted February 14, 2015 Well, they both unscrew. I have assumed that they take a Series 7 filter like the 12504 does Link to post Share on other sites More sharing options...
Guest Posted February 14, 2015 Share #16 Posted February 14, 2015 (edited) Talking about lens-hoods and our Leica-obsession with compact gear: the lens-hood for the Pentax 40mm pan-cake Pentax MH-RC Lens Hood for DA 40mm f/2.8 Lens 38742 B&H Photo gave me an idea: Why not use as a lens-hood a step-down filter adaptor ring, that costs less than 10 euro/$/UKP on ebay? They do not protrude at all (and are ok at keeping fingers off the lense's front glass). My question is: do they reduce flare as well as all the other shapes of lens-hoods? I got some step-down rings fitting with their exteriour screw-in diameter into some of my lenses between 35mm and 75mm. Subsequently I widened their interiour diameter to a 3:2 rectangular opening, after determining where this is located, after they're screwed in snug and repainted their inner margins black. Before I stopped down to the minimum aperture value of the lens (16 or in some cases 22) at infinity and made the rectangular openings big enough to avoid any vignetting at all. Now: are the multitude of lens-shade designs, which make the lens bigger (and cost quite a bit, when not included) capable of delivering more flare reduction? or ?

pico Posted February 15, 2015 Share #18 Posted February 15, 2015 BreakFree shouldn't hurt the paint. Be careful. Nothing helped and I should repaint the flat-black, which is simple. No matter. I am happy but it would have been a dream to have Series VII for the 50mm and 35mm Summilux. So be it. . Link to post Share on other sites More sharing options...
zeitz Posted February 15, 2015 Share #19 Posted February 15, 2015 Two approaches for stuck threads: - place the jointed parts between two pieces of wood. Give a sharp, but not violent, tap with a hammer along the center axis of the hood. You are just trying to get the metal to "ring" and achieve some axial movement before getting rotating movement. If still difficult to turn after several attempts, - use two rubber strap pipe wrenches to get a really good grip and apply the necessary force. Sears Craftsman sells two different sizes of these wrenches. You'll need two sets. I don't like using penetrating oil on camera equipment; I only use it if the threads are galled or damaged, say from a set screw. These two approaches have worked very well for me.

luigi bertolotti Posted February 15, 2015 Share #20 Posted February 15, 2015 Well, they both unscrew. I have assumed that they take a Series 7 filter like the 12504 does I think they unscrew for manufacturing reasons (the plastic equivalent, 12538, does not... plastic moulding is an easier process...) , but do not accomodate Series filters 1 Link to post Share on other sites More sharing options...
