gwelland Posted July 27, 2007 Share #141 Â Posted July 27, 2007 Advertisement (gone after registration) The Russian model was called TU-144 and actually flew before the Concorde. The first model plane I built when I was a kid. Â As I recall, it also crashed first too Link to post Share on other sites More sharing options...
SJP Posted March 24, 2008 Share #142 Â Posted March 24, 2008 I used my MATE this morning to capture the first "White Easter" I can recall & I noticed that the focussing unlike my other Leica lenses seems to have a certain "springiness". It feels like there is a spring pushing back when you move the focussing ring from close focus to infinite - so focussing "out" is harder than focussing "in". Although it works fine in all other respects I find this asymmetry in how it feels somewhat irritating. Â Comments anyone? Is this the way its should work or is it something that needs adjustment. It still has Leica guarantee on it & I would prefer sending it in within this period for obvious reasons. Â thanks Stephen Link to post Share on other sites More sharing options...
Paul Hart Posted March 24, 2008 Share #143 Â Posted March 24, 2008 Stephen: I have a still-in-warranty MATE, purchased recently from a forum member. After reading your post, I checked the focussing ring and yes, it is a touch firmer moving towards infinity than away from it. Â I hadn't noticed it till I read your post, and would assume it's normal. If you've ever seen a picture of the cutaway version of this lens, you'll know how complex it is, and minor foibles like this perhaps should not surprise us.

marknorton Posted March 24, 2008 Share #144 Â Posted March 24, 2008 Same here, I have both generations of MATE and this effect is more pronounced on the second generation than the first, if my examples are anything to go by. Link to post Share on other sites More sharing options...

gravastar Posted March 24, 2008 Share #146 Â Posted March 24, 2008 Mine is second generation and I must have the odd one out . It's uniformly stiff in both directions irrespective of the focal length. Â Bob. Link to post Share on other sites More sharing options...

If so, I think I was the original owner - lovely lens, it didn't work for me because it didn't focus as closely as I would like, but I used it a great deal and it did a grand job, mostly on trips abroad where I wanted to travel light. Â I'm glad it's gone to another good home! (and isn't Tim a nice character). Link to post Share on other sites More sharing options...
SJP Posted March 24, 2008 Share #148  Posted March 24, 2008 Mine is second generation and I must have the odd one out . It's uniformly stiff in both directions irrespective of the focal length. Bob. Thanks everyone for your comments. I have the latest 2nd generation version (i.e. including the 6bit coding) & the 'springiness' sounds consistent with what is reported above.  Now all i need to do is to whack it at the appropriate place to achieve the desired uniform stiffness reported by Bob. Or should I throw some sand into the workings? Problems, problems.... Link to post Share on other sites More sharing options...
Paul Hart Posted March 24, 2008 Share #149 Â Posted March 24, 2008 Hi Jono: yes, twas he who sold it to me. Still has your name on the passport! It's a great lens, and I'm very surprised at how close it is to my prime lenses. I also find I can nail the focussing accurately every time, so I think I'll be keeping it for a good while. Â It was a very pleasant and civilised transaction with Tim. Link to post Share on other sites More sharing options...
