stunsworth Posted August 4, 2012 Share #82 Posted August 4, 2012 12 posts on this forum only, all supporting SLR Magic....... You are not the first to notice this. Regardless, mechanical failures apart, using the non-coupled version of the lens removes the most irksome issues with this lens. I.e. misaligned rangefinder and focus shift when stopping down. The fact that it's glued together is almost secondary to the problems those cause. Link to post Share on other sites More sharing options...

brianv Posted August 4, 2012 Share #84 Posted August 4, 2012 Wait for the M10 and then perhaps you might know the answer. Speaking for today: Because the title of this thread does not address only the LM version and there were false pretenses that addressed the HyperPrime T0.95 and SLR Magic in general. Leica invented the M Mount and was introduced in 1954 with the M3. An M-Mount lens is a well known term. The term "LM" mount is something created by SLRMagic to differentiate their uncoupled lens from a real RF coupled M-Mount lens. Maybe they could use a different term for the uncoupled lens. M-Mount lenses are RF coupled. LM mount is not a term for RF coupled mount in the Leica community- except for this one lens. They got it wrong. Maybe they should use M-Mount and UM-Mount for their line of lenses. for more details of the shortcomings of the SLRMagic lens, see this thread on getdpi: http://forum.getdpi.com/forum/leica-m-x-r/37292-slr-magic-hyperprime-lm-50mm-t0-95-review.html Link to post Share on other sites More sharing options...
stunsworth Posted August 4, 2012 Share #85 Posted August 4, 2012 So SLR Magic are now saying that Leica also use Loctite in their lenses. It appears they do, but Leica use it as intended to hold screws tight, not to provide structural integrity. What a muppett. Link to post Share on other sites More sharing options...

pico Posted August 4, 2012 Share #87 Posted August 4, 2012 Advertisement (gone after registration) Maybe they could use a different term for the uncoupled lens. They do - their cine lens which is the origin of the 'magic'. As a cine lens it might be most excellent. Link to post Share on other sites More sharing options...
brianv Posted August 4, 2012 Share #88 Posted August 4, 2012 I guess, you mean the LM-Version because the CINE version that I own has an M-mount (but no RF-coupling) as well. This statement threw me- I thought the company was differentiating LM as a Mount, not the name of the lens. The "L" in "LM" is for Loctite. Link to post Share on other sites More sharing options...
ashwinrao1 Posted August 4, 2012 Share #89 Posted August 4, 2012 I note that Ashwin Rao, who is a frequent contributor and reviewer on Steve Huff's site, has just put his Hyperprime up for sale. It was an early copy and a custom order along with Steve Huff's lens that has 'stealth black writing' on the front ring; he implies that it's to partly fund the purchase of an M-Monochrom. Pete. Yup, that's exactly the case. I actually only became aware of the issues through conversations privately with Stephen Patterson, who had issues that were very real. We both had an opportunity to try the lens at a workshop back in January, and both of us came away favorably impressed at that time enough to ask to be beta-testers. Unlike Stephen, who received his lens a few weeks (? months?) before me, I haven't had any issues to date with my copy of this lens. What appears to be fact of the matter is that at least 2 or 3 of the original beta-tested lenses went south, due to manufacturing or focus calibration issues (or both), from what I have been gathering, and as a result, several who initially reviewed the lens favorably have put out warnings that the product may not be ready for primetime. I think this is a fair assessment in many ways, as one may not know if they have gotten a good copy or a dud. If I am not mistaken, Steve Huff did put up this warning, but qualified his statement, indicating that his copy had not experienced any mechanical failures. Neither has mine. As I hadn't had issues, I hadn't really gone browsing about issues with the lens until this AM, when I came across a bunch of warnings about the lens and its manufacture, as my orignal buyer for the lens backed out for those reasons (I did provide him a full refund and took the lens back). I subsequently came across this thread, as a fellow member from another forum had asked for my opinion on the lens, given that I had posted the lens for sale. Fingers crossed, I too hope that I or any proposed buyer don't have any issues with the lens, moving forward. The lens has a unique, and to my eyes, lovely rendering that some will love and others will not: For what it's worth, here's my real world experience with the lens, as someone who's used it extensively over 3 months or so: I know that according to some here, my photos aren't worth much consideration, but I only share them as an example of what I have been able to achieve when using the lens on the M9 (and occasionally XP1) The Monochrom is a costly camera, and like many of us, I am hoping to swap a bit of gear to gather funds to help defray the cost an expensive coming purchase...

ashwinrao1 Posted August 4, 2012 Share #90 Posted August 4, 2012 Priceless! This whole thing has been so predictable. I'll say it again, I'd rather blow my brains out before I'd go on a groupie-shoot with these guys. Now, I would buy all of Chris Weeks' drinks for the day to hang out and shoot with him. He is the anti-groupie blogger. Oh, wait, he isn't a blogger he is actually a professional photographer. Thirty-Five 'Lux Really, Rick? You don't even know me, and if you feel the need to criticize me, I wish you'd choose your choice of words with something that stings a bit less than "blow my brains out".....this type of commentary is frustrating, but I guess it just comes with the territory....but you do realize that it still hurts me a bit?

brianv Posted August 4, 2012 Share #91 Posted August 4, 2012 Steve Huff and Ashwin's experience are quite different from Stephen Patterson's experience. I wonder if there are two or more version of the RF coupled version of the lens. Hand-made/hand-machined versions that might be better constructed vs a production prototype meant to economize? Just conjecture, but the experience of the individuals using the lens is very different. Given the cost of this lens, having someone like DAG or Sherry inspect the construction of the individual lens would be reassuring to a potential buyer. The company has not issued any statements that would be reassuring to anyone. Link to post Share on other sites More sharing options...
brianv Posted August 4, 2012 Share #92 Posted August 4, 2012 AHH! I need an extra post. This will be 667. I sold all the equipment required to fund the M Monochrom. Nothing faster that F1.5. And I used nail Polish for the set screws. Link to post Share on other sites More sharing options...

TomB_tx Posted August 5, 2012 Share #94 Posted August 5, 2012 I wonder if there are two or more version of the RF coupled version of the lens. Hand-made/hand-machined versions that might be better constructed vs a production prototype meant to economize? Just conjecture, but the experience of the individuals using the lens is very different. Nearly 50 years ago in a summer lab job we experimented with a Loctite-bonded mechanical assembly for a pump. The 50 prototypes we assembled and tested extensively worked great. I heard much later that when it went into production it was a disaster. Obviously there were differences in either tolerances or processing (cleanliness, temperature control, or application) in production that made it unreliable. There may well be a similar situation here, where their prototypes differ from their production in some way that they haven't yet identified. It may be possible for them to find and correct the variations, but once a product gets a reputation like this it is wiser to change the construction.

Steve, There are a number of different Loctite products of which Threadlocker is one that is designed to prevent screws from unscrewing. I don't recall where the information that SLR Magic has used Threadlocker to build its lenses came from but it seems likely (read: I hope) that it'd have used a different Loctite product. Pete.

3D-Kraft.com Posted August 5, 2012 Share #97 Posted August 5, 2012 "M Lens" is in the title; that indicates to me that it only concerns the Leica M-mount version ("LM") of this lens. Pete. The CINE version has M-mount as well. If the M10 provides a more up-to-date focussing system (e.g. a hybrid viewfinder allowing more precise focusing through magnifying EVF), there may be good reasons to use that lens on a future Leica body as well. 12 posts on this forum only, all supporting SLR Magic....... I prefer forums with a wider spectrum and open minded participants. If this is a forum for fanboys only, sorry to interrupt you as I returned the M9 due to too many limitations. All I kept was the excellent Summilux 50/1.4 ASPH - together with the HyperPrime. Link to post Share on other sites More sharing options...

I need to groom my calluses... First off, I didn't criticize you. You have me confused with someone else here. I did say that I'm very much not into blogger groupie shoots. You are. Good for you, really. I mean that. I respect your right to enjoy that sort of thing. I am sorry if I hurt your feelings. But, it doesn't change my opinion that groupie shoots aren't for me. I'll try again without the inflammatory gun references; I would rather have a frontal-lobotomy than conform to a group (actually, I'd rather have a bottle-in-front-of-me).
