Nitnaros Posted October 10, 2008 Share #1 Posted October 10, 2008 Advertisement (gone after registration) My R9-DMR came finally back from Leica NJ repair; right after I acquired it, it needed to go there due to fuzzy images - "alignment of DMR to R9" according repair report (it did not focus properly). I had thought it was the focus screen, but it wasn't... I haveso far the 15-2.8/35-lux/60-f2.8 and I am thinking of adding either the 80-lux or the 90-2.0-apo. I am aware of the different drawing of both lenses. What I don't know is how sharp the 80 is wide-open at its close-focus distance - ? Comments/images appreciated.

The Cron to 0.7 m (larger magnification than 80 also due to longer focal length). If you want it sharp the 90AA performs great and f/2 is sufficient because DOF is extremely shallow already. The Lux is still a good performer has less distortion and is more versatile as a bokeh portrait lens. Maximum close up sharpness means 100 macro if you want more light the 90AA is great if you need a lot more light and have tried the bokeh of the 80 go for it.

fingerprinz Posted October 10, 2008 Share #3 Posted October 10, 2008 The Summilux-R 80/1.4 is very sharp in the center and produces an increadible bokeh. I use it mainly for close-ups.

fernando_b Posted October 10, 2008 Share #4 Posted October 10, 2008 This is at f/1.4 and at its minimum focusing distance. Consider that some blur is due to very slow exposure time (1/15 hand held). You can clearly read the letters. Fernando. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

Nitnaros Posted October 10, 2008 Author Share #5 Posted October 10, 2008 Thank you, folks, for your responses. So one interesting combo would be to go with the 80-lux and add the 100-macro later. That would provide the very good portrait capabilities of the 80, and I could use the 100 for very close distance portraits. I was not considering the 100-macro so far, although everybody says it is an excellent lens, since I bought the 60-macro, which is very affordable to have in used condition (and I really like it). Any close distance portraits with the 80-lux from somebody? Peter Link to post Share on other sites More sharing options...
Overgaard Posted October 10, 2008 Share #6 Posted October 10, 2008 The 80mm may not appear as sharp as the 90mm f/2 but the details are better, more 3D and more characteristic. The 80mm has a very lively way of handling light which also, with the DMR make it look more "film like" at least in my opinion. Here's some slide shots with the 80mm: leica.overgaard.dk - Thorsten Overgaard's Leica Pages - Leitz Summilux-R 80mm f1.4 test photos and samples And here's some R9/DMR shots - the first two on the page are 80mm portraits (no 2 with the sun straight into the lens): leica.overgaard.dk - Thorsten Overgaard's Leica Sites Leica DMR digital back for the Leica R8 and R9 SLR cameras test photos, manual and links Link to post Share on other sites More sharing options...
carstenw Posted October 11, 2008 Share #7 Posted October 11, 2008 Advertisement (gone after registration) I have never used a 90AA-R, but I own a 90AA-M and a 75 Lux, and used to own an 80 Lux, which I used on a 5D. The 75 Lux is great, but for my taste, a tad too sharp wide open. The 90AA is awesome, but my favorite lens of all time (so far), remains the 80 Lux. It was not the most sharp lens wide open, but it has a really special look, and I would never have traded it, except that I ditched my SLR stuff completely, and went for an M set. One day, I will own the 80 Lux again. If you want to talk about maximum sharpness, get the 90AA, but if you want an awesome lens with legendary portrait characteristics, which sharpens up amazingly well by f/2.8, get the 80 Lux. You can get the 90AA later too, if you really need it for something else. Link to post Share on other sites More sharing options...

carstenw Posted October 11, 2008 Share #10 Posted October 11, 2008 No, softer. The 75 Lux was a little easier to design, due to the lesser flange distance, apparently. However, they are very close in look. The 75 Lux on FF would probably be closer to the 80 Lux look that I love so much. Using only the centre 1.33 part artificially "improves" the lens.

Jamie Roberts Posted October 11, 2008 Share #11 Posted October 11, 2008 Yeah, there's something about the 80R lux that reminds me more of the Nocti than the 75 Lux on the M system. It has the same fabulous flare characteristics (meaning it does special things with light in adverse // low-light conditions). But the 80R is sharper than the Nocti from 1.4 on.. so in that way it's more like the 75.. but it is softer in sharpness as Carsten notes, but it still has better contrast characteristics... so one of my all-time favourites too, and a really great lens with lots of character.

rsolomon Posted October 12, 2008 Share #12 Posted October 12, 2008 i can't answer your question directly but can tell you the 80 1.4 is my favorite lens. I use it on the R9, DMR, and Digilux 3...... its a damn good lens ! Link to post Share on other sites More sharing options...
locator Posted October 12, 2008 Share #13 Posted October 12, 2008 Softer at maximum aperture, for sharper imaging, you just have to turn from 2 to 2.4 and you get the edge. If you want sharper images at maximum aperture, go for the 50 lux Here are some images taken with the 80 lux and DMR Note aperture and speed values on file names Welcome, dear visitor!

fernando_b Posted October 13, 2008 Share #15 Posted October 13, 2008 Carsten, I know that mathematical modelling don't catch always 100% of the real life. However if you look at the "official" MTF curves published by Leica, at f/1.4 the R80 is sharper than the M75. If you got the opposite result, it could be due to other factors. Fernando.

carstenw Posted October 13, 2008 Share #16 Posted October 13, 2008 It might be sharper, but I think what contributes to the 80 Lux looking softer is its glow. It just has more glow than the 75 Lux, at least in my memory. I recall finding the 75 Lux slightly too sharp after buying it, being used to the 80 Lux, but I didn't actually own both at the same time, so it is possible my mind is playing cruel tricks on me. I have heard others say the same though. Link to post Share on other sites More sharing options...
fernando_b Posted October 13, 2008 Share #17 Posted October 13, 2008 Yes, could be that factor. Actually, the MTF at 5, 10, 20 and 40 lp/mm can't show the glow/flare behaviour of a lens. Regards, Fernando. Link to post Share on other sites More sharing options...
carstenw Posted October 13, 2008 Share #18 Posted October 13, 2008 In fact, thinking more about this, I am getting more and more convinced that this is exactly what makes the 80 Lux so special: that soft-sharp look. More softness, due to coma or glare or something, yet sharper due to other characteristics. The 75 Lux is just a bit cleaner overall, and while it is really nice, nicer than almost any other portrait lens on that platform, I still prefer the 80 Lux. Like Jamie said, on the M8, the Noctilux comes closer to the 80 Lux than the 75 Lux does. Link to post Share on other sites More sharing options...
