Advertisement Posted February 21, 2016 Posted February 21, 2016 Hi otto.f, Take a look here Rumor - Three new Leica M lenses tomorrow?. I'm sure you'll find what you were looking for!
DezFoto Posted February 24, 2016 Share #222 Posted February 24, 2016 These are just normal sunburst patterns and not flare. This is one of the most flare resistant lenses. Also, the link you have to digipixelpop is a poor review and they even disclosed at the end of the article that they had a bad copy that flared. If, you go to the end of the review they state they received a new copy and had no flare problems. Tim Ashley, that you linked to, is a cool guy and a member that started a website that was really pretty good, but he got hung up in field curvature, sharpness and in the end tried to hang the mantle of "boring lens" on the 28 Summicron. It didn't stick. A lens or thing can't be boring. The 28 Summicron is an "exciting" lens and focal length (kidding). But, this is my most used lens. Rick Actually, I did not receive a new copy that didn't flare, I got a brief chance to use a brand new version and the flare was less invasive than on my copy. I had my lens CLA'd and that reduced the flare, but it is still there. I would be wary of non-6bit coded lenses as it appears that either the lens coatings on older copies are inferior and were changed, or they somehow deteriorate with time. I'm sorry you found my review to be "poor" but I did write a followup here: http://www.digipixelpop.com/?p=1252 Link to post Share on other sites More sharing options...
sdk Posted February 24, 2016 Share #223 Posted February 24, 2016 I have the old and new 28mm Elmarit-M ASPH lenses now, but have not had time to do any serious side by side comparisons with my M-P. New lens seems very good, however. Link to post Share on other sites More sharing options...

Understandable that you would pull that one word "poor" out of my comments that I used to describe your article. After I reread my post later, my wording actually bothered me too. I was going to write a post and explain that I actually liked and enjoyed reading your review but, found the part about the flare as not at all what I experience with my coded 28 Summilux. This flare part of the review I felt was incorrect and it made the review not an article that I would highly recommend... but, the entirety of the article was not therefor all poor. I apologize for the broad brush strokes a painted your entire article with, and that I used the wrong word at that. Rick Link to post Share on other sites More sharing options...

Rick Hi Rick, No apology or explanation necessary, I was disappointed but everyone has a right to their opinion, whether it be positive or negative. I have spoken with other users that have had the same issue with their 28 'Cron, so I don't feel like it's an isolated issue, though it's likely not an epidemic. That being said, the reason for my disclaimer at the end was to make it clear that that was the experience I had with my particular copy and others may not have the same issue with theirs but as always, a buyer should test a used lens before money changes hands. After the CLA the flare was reduced to a level I found acceptable, albeit still much more pronounced than with my Zeiss lenses and easier to induce. To me the bothersome part is the color of the flare (purplish), but most of my Leica lenses throw a similar color when flaring. I've learned to live with it, or work around it, or paint a little green into it when necessary. Link to post Share on other sites More sharing options...

Geoffrey James Posted February 24, 2016 Share #228 Posted February 24, 2016 I have had more flare problems with the 28 Summicron when using a UV filter. It really makes the lens more flare-prone. Haven't had time to follow this long thread, but Jean at Camtec, the Montreal Leica Boutique, makes some good points. Probably no need to do anything to the 35 Cron, and the best thing you can do for the 28 Cron is improve the construction. The screws on the back keeping it all together are definitely under-engineered. My 28 took a bump at the airport, and the screws started coming out. I managed to find an optician in Paris with the rights screw=driver, and continued with my shoot for the week with the vertical way out of alignment. Jean makes the point that the most improved lens is the 28 Elmarit. Better distortion control, and better resolution. With its small size, it makes a rather seductive package.

Jean makes the point that the most improved lens is the 28 Elmarit. Better distortion control, and better resolution. With its small size, it makes a rather seductive package. It is the screws holding the front part that keep coming loose on my 28 ASPH Summicron. The front is then free to unscrew. The poor quality screws on my 28 are so chewed up from everyone and their uncle trying to tighten them (they were not in good condition when I got the lens), that they can no longer be tightened or removed. It will need to go back to Leica to have them replaced. I suspect they may replace the entire barrel, because they don't know how to remove a wholly chewed up small grub screw. You build a dam round the screw with putty and with a cone shaped hole in the middle to act as a guide towards the screw. You then put a steel rod the same diameter as the screw into an electric welder, that has a pedal strike switch and set to low current. Then touch the steel rod to the damaged screw, press the strike pedal very briefly and the rod will weld itself to the screw. You then use a pair of grips to twist the rod and the screw usually comes out with no problems. If it has been put in with thread locker, the heat generated in the spot welding process, will have loosened this. However, you would have to be brave to do this on a lens.

semi-ambivalent Posted February 25, 2016 Share #230 Posted February 25, 2016 Jean makes the point that the most improved lens is the 28 Elmarit. Better distortion control, and better resolution. With its small size, it makes a rather seductive package. The 28 Elmarit has always been praised for its high resolution. Now that there's a new 28 Elmarit out there it has better resolution. Shooting film, I'll likely never see any difference but I suspect all of this is in the range of pixel peeping. Can't speak to the rest of the ad copy unless I rent the thing but I'm not going to do that. Hope they sell a ton of them. s-a Link to post Share on other sites More sharing options...
Geoffrey James Posted February 25, 2016 Share #231 Posted February 25, 2016 It was actually the back screws that came out on mine -- making it impossible to focus properly. I had a front-element problem with the V4 35 Cron. My repair guy tells me that the element is aligned by the thread, (like the hood of the Q), an edgy way of doing things. I have a V4 that is for all intents and purposes useless. Link to post Share on other sites More sharing options...

Tmuussoni Posted February 28, 2016 Share #233 Posted February 28, 2016 http://www.getdpi.com/forum/leica/57393-new-leica-lenses-announced.html A comparison of the new Elmarit-M 28 ASPH. It certainly performs better than the older version. On the SL the difference is huge. With M 240 the difference is there but is is considerably smaller. Still no comparison with the new and old Summicron.. Patiently waiting... EDIT: Never mind, my reading comprehension is poor today. someone else already posted the comparison on previous page of this thread and I missed it. Well, still waiting for comparison with new and old Summicron. Link to post Share on other sites More sharing options...

EDIT: Never mind, my reading comprehension is poor today. someone else already posted the comparison on previous page of this thread and I missed it. Well, still waiting for comparison with new and old Summicron. Thanks, so it looks like these improvements are, as others have said, aimed at consistent image quality across multiple Leica camera platforms like SL or T, rather than the most popular current M lens users, which seem to be M8/M9/M240/M242/Monochrom. I believe LR6 can adequately perform distortion and vignetting, chromatic aberration, horizontal and vertical perspective lens profile corrections on this minor amount, and I prefer the more compact lens hood and construction on the older Summicron silver version, so I do not think a replacement is worthwhile. If you are just starting out with the SL, then most definitely, and you're already expecting a larger camera, anyway Link to post Share on other sites More sharing options...
CheshireCat Posted March 3, 2016 Share #235 Posted March 3, 2016 I believe LR6 can adequately perform distortion and vignetting, chromatic aberration, horizontal and vertical perspective lens profile corrections on this minor amount None of these LR6 corrections can improve resolution at the edges like the new revised optics.

jaapv Posted March 3, 2016 Share #236 Posted March 3, 2016 The common misconception. "Sharpening" in postprocessing has nothing to do with (impossibly) increasing resolution, it is nothing but manipulating edge contrast giving the optical illusion of greater sharpness.

helged Posted March 3, 2016 Share #237 Posted March 3, 2016 Back to the new lenses, and then in particular the new 28 Cron and 28 Elmarit: Can anyone test these lenses wrt the "red edge syndrome" (reddish/magenta miscolouring towards the edges) on an M and/or SL, preferably with and without lens detection activated? Images of white buildings, sand beaches, clouds or snow will do the job... Yes, these artefacts can be mediated in post-processing (Flat Field in LightRoom, Lens Cast Corrections in C1, CornerFix, etc.), but it would be interesting to know how the new lenses behaves compared to the previous ones.

CheshireCat Posted March 4, 2016 Share #239 Posted March 4, 2016 Yes, and I never mentioned "sharpening." We were talking about corner sharpness here. Therefore you mentioned it implicitly: I believe LR6 can adequately perform distortion and vignetting, chromatic aberration, horizontal and vertical perspective lens profile corrections on this minor amount And the minor amount was of aberrations affecting sharpness. Which unfortunately, LR6 cannot actually fix, like jaapv has pointed out. Link to post Share on other sites More sharing options...
