Advertisement Posted November 25, 2015 Posted November 25, 2015 Hi don daniel, Take a look here New: LEICA SUMMILUX-M 28 mm f/1.4 ASPH.. I'm sure you'll find what you were looking for!
hiepphotog Posted November 25, 2015 Share #102 Posted November 25, 2015 I'll see what I can do. It is very cloudy right now. Maybe I can get a tripod from the high school where I work. You strictly want ISO 1600 and aperture 1.4, right? Thank you Daniel. Mainly I want to see the coma performance at f/1.4. ISO 1600 and 8 second exposure are just the settings to get no star trail. I'm not quite sure how good the M240 can handle the sky at ISO 3200. But that would be a better ISO to overexpose a bit and balance the corner vignetting. The wonderful 50 APO I have doesn't do so hot with coma at WO, but 50 is not the focal length to shoot wide-field astro for me. Link to post Share on other sites More sharing options...
don daniel Posted November 25, 2015 Share #103 Posted November 25, 2015 We will not see the stars around here for a few days. The weather is too bad. Maybe next week I can do something for you. But if I point the camera to the sky there will be much less light than in your picture, where there are more light sources than the stars. So 8 seconds shutter exposure time won't be enough.

Thank you, Daniel. For astrophtography, additional light sources would compete with the visibility of stars. Right now it's full moon so the visibility (as in the stars would be overwhelmed by the brightness of the moon) might not be as great as it should but should be good enough for coma evaluation purpose. So you might be surprised how much stars you can pick up at 8s, ISO 1600 and 1.4. These settings worked on my ZM 35/1.4 and Lux 50/1.4. 1 Link to post Share on other sites More sharing options...
Rick Posted November 26, 2015 Share #105 Posted November 26, 2015 Hello Hiep Sorry that I didn't notice my inbox was full. I have taken care of that know. But I must disappoint you. I do not even have a tripod to do a shot as you wish. Maybe I can do a longtime exposure shot of citylights (aperture 1.4) this weekend putting the camera somewhere down on the floor or on a bridge railing. But it is possible that I do not have the time or enough motivation to test things I rarely use. I'm liking you more and more! Link to post Share on other sites More sharing options...
Peter H Posted November 29, 2015 Share #106 Posted November 29, 2015 ................ Here is a quick snapshot at ISO 2000 with the ZM 35/1.4 at WO during a full moon. ......................................... I have never taken the sky at night, so I'm as far from an expert as it's possible to be. As a result I don't understand why there are stars "in front of" the clouds. Is it because the clouds were moving very quickly, or because the clouds were thin and the stars appeared to shine through them because of the long exposure? Thanks Link to post Share on other sites More sharing options...

Thanks Peter, I don't remember it was a windy night, maybe light breezes as always in the desert. So it's most likely that those stars shined through the thin clouds. Unfortunately, this particular image, being an usual coma test shot, didn't make through the first run of my annual clean up so I can't really zoom in to see for sure. To be honest, this picture captured more than my eyes could see. Personally, I think this is the only reason I would buy an f/1.4 WA/UWA (well 28 is the long end of WA).

Rick Posted November 30, 2015 Share #108 Posted November 30, 2015 You are very kind, Rick. My subjects are German (literature and language) and History. But my work at school is not limited to these subjects. It is also my interest and job to document events at my school with my camera. I am commissioned to publish an official gazette. I live and work near Basel in Switzerland. My students are 15-19 years old. We don't have colleges here. When they graduate from our high school they change to university directly. Because I feel a little guilty about your wish to buy a Summilux 28 I want to add that this lens has also its flaws. There is a remarkable amount of chromatic aberration, purple fringe, that in some shots has to be treated in post processing. It is more than what you see from the Summicron. In Lightroom this is done by one single click, in Capture One, the converter I use, this can be little more annoying. And to complete this I must mention that the Summilux has a more complex distortion than the Summicron. The latter can be corrected easily, because it is a simple barrel distortion, the former needs a special profile which does not yet exist in LR. At first sight the Summilux seems better corrected than the Summicron, because you don't see the barrel. Lines bend to the outside again in the corners. In most situation this is not an issue. The amount of distortion is small, but in architectural shots you can notice it is there. Until now this has not been a pain to me. I hope I managed to put this into clear words. Don, I went to the Leica Store here where they have one for sale and considered it again. But, you don't need to feel guilty... I didn't buy it. It is just too large for me. It is larger than my 35 Summilux FLE and a lot larger than my 28 Summicron. I just wouldn't mount it on the camera for what I do and how I enjoy taking pictures. I guess I'll stick with the Summicron. Thanks for your helpful comments. Rick Link to post Share on other sites More sharing options...
asiafish Posted December 1, 2015 Share #109 Posted December 1, 2015 I was so happy to hear of this lens' release. I sat back, waited a few months and then snagged a very gently used 28mm f/2.8 Elmarit ASPH for just over $1000. 2 Link to post Share on other sites More sharing options...
John Perkins Posted December 1, 2015 Share #110 Posted December 1, 2015 Might I suggest that someone who has both lenses do an out-of-focus-area comparison between this lens and the 35mm Summilux ASPH FLE? At, say, 1.4 and 2.0, with both high/low contrast/backlit situations? Stopped down I doubt there are many tangible differences in performance.

Rick Rick, I liked the Summicron 28mm much more than the Summilux 35mm FLE. So I sold the 35 FLE. I do not miss 35mm as a focal length for an M. I have got a Df and a Nikkor 35mm/1.4G. Then I tried the Summilux 28mm and what shall I say? This is MY lens. So I sold the Summicron. I simply do not carry another lens with me, when I go out shooting with the Summilux 28mm on the M. That's how I cope with the weight of this piece of glass. If I had the Summilux 35 and liked this focal length, then I would not buy the Summilux 28mm.

Herr Barnack Posted December 1, 2015 Share #112 Posted December 1, 2015 Well, in the vein of "The (Fast) Glass is half full", the 28 'Lux showed up today...still awaiting the Monochrom 246... That beats the hell out of empty mailbox! Link to post Share on other sites More sharing options...
Guest Posted December 1, 2015 Share #113 Posted December 1, 2015 (edited) What's the difference btw between the old and the new SummiCRON 28mm other than bigger filters for the new one? I think of this new version of the 2.0/28mm mentioned in the German section of our forum, which was first presented here - please scroll a bit down the page for the photos of the lens: http://www.pc-magazin.de/news/meister-camera-leica-m9-p-meisterstueck-1322761.html The 1.4/28mm was at first part of the stainless steel Leica 100 special edition, before it became a regular part of the Leica M lens set on general offer.

Herr Barnack Posted December 2, 2015 Share #114 Posted December 2, 2015 The current 28/2 Summicron uses 46mm filters; the 28/1.4 Summilux uses 49mm filters. I had a 28/2 Summicron which I bought in 2003; it also used 46mm filters. The 28/2 still uses 46mm filters as far as I know. Link to post Share on other sites More sharing options...
awesom3 Posted December 6, 2015 Share #115 Posted December 6, 2015 Q: Does the lens come with a ring you can screw onto the front thread when you're not using the hood? I think the 35 FLE shipped with such a ring. Link to post Share on other sites More sharing options...

J S H Posted December 8, 2015 Share #118 Posted December 8, 2015 Thank you Daniel. Mainly I want to see the coma performance at f/1.4.

The wonderful 50 APO I have doesn't do so hot with coma at WO, but 50 is not the focal length to shoot wide-field astro for me. This really is a great lens. Usable for stars wide open, but you need to focus a little short of infinity to minimize the coma in the extreme corners (it doesn't go away, but improves a little by tweaking the focus). The coma problems are only in the corners...the edge of the frame is fine. By F2 coma is under control and should not be a problem for critical work, but you still need to find optimal focus for best performance across the frame. The EVF in the SL makes this a simple task. In my experience, the 35 FLE is a little better in this regard. The 35 is completely usable wide open for astrophotography. However, the 28 is definitely more impressive when all factors are considered and may be the best lens I've ever owned. Here is a photo with the 28 Summilux on the SL. This was shot at F2, 5 sec exposure @ ISO 3200 First image is full frame, second is actual pixels from the upper left corner. I will try to shoot some tests wide open when the weather allows.

I actually did the test for my own knowledge, then stumbled across the thread and thought it might be good info to pass along. It's a great lens, and it is also an excellent performer on the SL. Here's a daylight shot. Probably around F4. Welcome, dear visitor!
