robsteve Posted November 14, 2007 Share #61 Posted November 14, 2007 Advertisement (gone after registration) The problem I've found with the CV caps it that the felt wears down after a time and the caps won't stay on the lens. The worst lens for this is the 15mm, I assume because it isn't a full lens hood, and helps explain why it's the only lens I have with a scratch on the front element. Steve: I dont know if this works with the CV felt, but on the old Leica lens caps with the felt, the cure was to get the felt soaked with water, fluff it up a bit when it is wet and then let it dry. It will then be a tight fit once again. As for the metal caps, I don't like them when they fit on so far to touch the aperture ring. They will tend to scratch the anodization on the aperture ring. I had this happen with the new 50mm f2.8 Elmarit-m and just started using a Leica plastic push on cap instead. Link to post Share on other sites More sharing options...

stunsworth Posted November 14, 2007 Share #62 Posted November 14, 2007 Hi Robert, I've tried that, but the felt seems to revert to it's flattened surface after just a few days. It isn't likely to be too much of a problem if I'm more careful in future. Link to post Share on other sites More sharing options...
sean_reid Posted November 14, 2007 Share #63 Posted November 14, 2007 The focus action, which seemed a bit light on the pre-production Summarits, now feels just fine on the production lenses. Cheers, Sean Link to post Share on other sites More sharing options...
sean_reid Posted November 16, 2007 Share #64 Posted November 16, 2007 I'm doing the res. tests on the 75s right now (Summarit plus comparison lenses) and I can say that the 75 Summarit shows *excellent* resolution across the field wide open. It's really impressive, actually - a thing of beauty. I haven't looked at the results from the other two lenses yet but my jaw dropped on on the F/2.5 results on the new res. test set up.

sean_reid Posted November 16, 2007 Share #65 Posted November 16, 2007 Also, that story about the Summarits being F/2.4 (in reality) seems to be right on the money for the 75 at least. At a nominal F/2.5 it seems to be exactly a half-stop under the Summicron at F/2.0. The Heliar is more like an F/2.6 it seems. Cheers, Sean Link to post Share on other sites More sharing options...
gesper Posted November 16, 2007 Share #66 Posted November 16, 2007 Can't wait to see your full test, Sean. My biggest question will be is there enough difference to make it worth selling my CV 75 and trading up. Link to post Share on other sites More sharing options...
innerimager Posted November 16, 2007 Share #67 Posted November 16, 2007 Advertisement (gone after registration) Can't wait to see your full test, Sean. My biggest question will be is there enough difference to make it worth selling my CV 75 and trading up. Another (bigger?) question will be is there enough difference to sell the 75 cron and trade down? ;>) best....Peter Link to post Share on other sites More sharing options...
peter_n Posted November 17, 2007 Share #68 Posted November 17, 2007 What's the minimum focus on the Summarit? It's 0.7M on the 75mm Summicron. Link to post Share on other sites More sharing options...
sean_reid Posted November 17, 2007 Share #69 Posted November 17, 2007 What's the minimum focus on the Summarit? It's 0.7M on the 75mm Summicron. Looks like about .8 m, roughly. Link to post Share on other sites More sharing options...
c6gowin Posted November 17, 2007 Author Share #70 Posted November 17, 2007 The Leica literature lists the minimum focus distance as 0.9 m, but the focus does turn slightly past the 0.9 m mark so 0.8 m is a good estimate without taking an actual measurement. I agree with Sean that the focus action feels good. It appears to have a short focus throw of just less than 90 degrees from minimum to infinity. I have finally got some time now to do some more testing and it is looking great. I have already posted examples which show the out of focus rendering at f2.5. I have also completed testing of focus shift and reported the results earlier in this thread. I am working on resolution tests and will post the results. It will be fun to compare my findings to Sean's and Guy's. I predict we are all going to win with this lens - the users and Leica. Link to post Share on other sites More sharing options...
robsteve Posted November 17, 2007 Share #71 Posted November 17, 2007 I am still not sure about the colour/contrast of the Summarits compared to the APO or ASPH lenses of the same range. From looking at Guy's puctures, the lenses are certainly sharp, but are still missing something. They have the look of the older lenses, color/contrast wise, but do not have the smooth colour and high contrast of the APO/ASPH equivalents. Link to post Share on other sites More sharing options...
hankg Posted November 17, 2007 Share #72 Posted November 17, 2007 The old 75 Summilux focused to 1 meter, the later model focuses closer -I think it's down to .7 but the additional close focusing may not be all that useful as quality deteriorates at those distances quite a bit. The 90/4 is the only current Leica lens that can perform optimally at it's closest focusing range. Link to post Share on other sites More sharing options...
Shootist Posted November 17, 2007 Share #73 Posted November 17, 2007 Not so sure about that. This was shot with a 75 Cron @ f/2 hand held @ 1/45. Yes the 90 Macro f/4 is optimized to do close up work better but the 75 Cron is no slouch, even wide open and up close. Welcome, dear visitor!

hankg Posted November 17, 2007 Share #74 Posted November 17, 2007 I was speaking about the Summilux and Summarit. I believe the Summicron has floating elements which gives it an edge but I would not expect it to match the 09/4 close up as it was optimized for longer distances -same goes for all the ASPH lenses some more so then others.

andybarton Posted November 17, 2007 Share #76 Posted November 17, 2007 Is anyone going to test these on a film M? Link to post Share on other sites More sharing options...
huwge Posted November 17, 2007 Share #77 Posted November 17, 2007 Just ordered mine - the chap in the shop was eulogising about the quality and I just caved. Have found that the 75 lux is only being used for indoors portrait work and is really too heavy to lug around as part of a 3 lens kit (24, 35 lux & ...). The apo 90 is also getting limited work as most of my landscape work is in the middle of a hike and I just prefer the 75 lux for people. Huw PS: Andy, once I have it I will also use with film. As and when I have something to post, I will. Link to post Share on other sites More sharing options...
c6gowin Posted November 18, 2007 Author Share #78 Posted November 18, 2007 Andy, I don't have a film M so I can't help you that. Sorry. I can't do a direct comparison with other 75mm lenses, but I will try to some get some similar shots with my 50 Lux ASPH and 90 AA to help better judge color/contrast. Personally, I am very pleased with the color/contrast of the 75mm Summarit. The Summarit images have a similar look to images taken with my other Leica lens when scrolling through them in Lightroom. However, the questions raise here have got me curious to take a more critical look. Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted November 18, 2007 Share #79 Posted November 18, 2007 Mark i don't have the 75 mm Summarit to test just the 35,50 and 90. But here is a shot today when i was running a test on the Summarits I shot this with my 75mm lux at 1.4. Now it was in the open shade . My test will be up in the morning have to process them but i did throw the 75 lux in there to match the 90mm wide open and that I will put up in the morning . But how does this look in terms against a similar 75mm summarit. I nailed the focus on this wide open at 1.4 be nice this is my kid. LOL Welcome, dear visitor!

c6gowin Posted November 18, 2007 Author Share #80 Posted November 18, 2007 That is a great portrait of your daughter, Guy. You should be proud. The Summarit can't match the creamy background of the Summilux at f1.4. However, I think the Summarit will look very much like the Summilux at f2.5. The Summarit is very sharp and has a smooth, but not harsh, out of focus area. It is too bad we cant do side-by-side comparison. Link to post Share on other sites More sharing options...
