Nice examples of what really sets this lens apart from the rest ...... the distinctive unobtrusive OOF rendering and the very smooth transition from the in focus areas into the OOF background....... it really emphasises the subject of the image without looking unnatural.

 

Of course you can see it clearly lacks the mythical micro-contrast so evident in much better Nikon and Canon lenses as outlined by Mr Khong and the other experts.....  :rolleyes:

Agreed - these last images just have something special about them, helped by careful selection of aperture to keep the subject sharp, without the transition to the out of focus areas distracting.  I'm loving what I see from this lens.  It would be good to see some portraits as well ...

Andrew, your images show depth. Thanks for posting. Let's see if I find time to do some comparisons. :)

You're all blind! Those images are ghastly, utterly ghastly. I don't know whether it's this that or the other but they're just horrible over saturated, over contrasted blobs of green. The OOF are way too high in contrast and saturation and I find myself needing to wear dark glasses to view them.

 

;)

 

Happily though, I have now found some very pleasing examples of images (portraits) made with the Summilux-SL. This is a lovely example:

It gives me hope that maybe this lens isn't quite the wankpuffin I thought it was.

Well, while I wouldn't be as offensive as this, I agree that those shots are oversaturated to my eye, and I find the OOF areas obtruding and nervous rather than receding.

Concerning #66, a lovely young lady but I suggest the out of focus areas are overdone, in this case one might remember people have actual hands and not blobs, though they can be softened to keep them from being distracting.

There’s no accounting for taste, I guess. Yet another image where a smaller aperture would have had the subject in focus. Instead, a bokeh sample.

 

Each to their own.

Thanks, thats a comparison I would love to see!

 

Andrew

I went out and compared the SL vs. the Canon 5DS R today (the latter using the Otus and the Sigma Art). Just some first impressions after having had a quick look at the pictures. First on the Sigma Art, for where it’s priced, it’s a pretty good lens for achieving subject separation with nice blur wide open. At first glance, the OOF areas look the same as from the Otus. Where it lags behind its more expensive “peer” is in contrast at f/1.4, but pictures still look acceptably sharp at that aperture, I would say, not too soft. As a result, it doesn’t capture all the tones wide open. Pink flowers, for example, will show more of a big blotch of pink on them rather than the whole range of tones. AF is unreliable for achieving critical focus when the plane of focus is very thin. One is better off setting the lens to manual in this case. Too bad. The 50 Summilux-SL is fast and pin point accurate in this respect. What a pleasure, I thought. On the Otus, it has better contrast wide open than the Sigma Art, meaning it captures more of the differences in tones and it distinguishes the boundaries of small areas with slightly different luminance better. As a result, the Otus pictures look slightly sharper. The Summilux-SL really knocks it out of the park here. Not only do the SL pictures look sharper but they also have more depth to my eyes. By the way, colors and AWB are off on the Canon files as they come out of the camera and it’s starts burning highlights at ISO 200 and starting at ISO 640 noise is unbearable at today’s standards. But that’s a different matter. The reason to use the 5DS R to compare is that the AA filter effect is cancelled so it can’t distort perceived sharpness. Also, it was interesting to see if 50 MP have any discernible effect on the way the lenses capture the tones. They do not but this could be because the 5DS R’s sensor is crap in terms of dynamic range and performance starts deteriorating after ISO 200 (I used ISO 100 mostly outside and ISO 200 indoors). And by the way, the Otus shows a lot of purple fringing wide open which the Summilux-SL miraculously does not even if the opcodes are removed. Go figure :). I will post pictures later mainly to show the difference in rendering between the lenses. I didn’t take the Sigma Art with me all day after I had determined that it’s good value for money with overall nice rendering but lagging behind the others in terms of contrast wide open. Wait till you see them.

The first three are harmless. Just for warm up. The most surprising thing about them is how good the Sigma Art looks. Focus is spot on the horse's head for all three. One has to look very closely to see that the Sigma Art is a bit softer than the Otus. Still, impressive. One can only get a sense that the Summilux-SL is special. All AWB by the cameras. They were opened in LR and not touched except lens profiles applied to all of them (and default sharpening) which means for the Canon lenses also correction of vignetting. To even the playing field also +30 on vignetting for the SL (lens corrections in LR do not include this for the SL files). The SL image was slightly straightened and upsized to 42 MP to even the pixel playing field with the Canon monster. Uncompressed versions here: https://www.smugmug.com/gallery/n-9J3jzS/

 

ISO 100, f/1.4, 1/200sec for all.

Here the Summilux-SL starts to set itself apart, IMO. One has to look at the uncompressed versions in the link. Focus point for the Sigma Art and the SL spot on the horse's head. Unfortunately, a bit off for the Otus. If one zooms in on the horse's head one can clearly see how much nicer the SL captures the differences in tones there and that this affords a sharper and three dimensional look to the object. Also, look closely at the coil of the horse.

 

All AWB by the cameras. They were opened in LR and not touched except lens profiles applied to all of them (and default sharpening) which means for the Canon lenses also correction of vignetting. So +30 on vignetting for the SL as well. The SL image was upsized to 42 MP to even the pixel playing field with the Canon monster.

More to follow tomorrow. Too tired now.

Three more. Focus with the Otus and the SL is spot on the pink flowers. Unfortunately, the Sigma Art is slightly to the front of that (big mistake to rely on AF). To me it's clear that the Summilux-SL effortlessly captures the range of green and pink of the flowerbed. It's not due to saturation or Tint. Contrast seems very high where the focus point is. These are all with AWB in the cameras and Tint is +20 for the SL and +6 for the Canon. 

 

SL opened in LR, Exposure +0.30, Vignetting adjusted +30.

Canon opened in LR, Exposure +0.50, lens profiles applied.

...... mmm .... well I have to say that at this resolution and on my iMac I would have passed all 3 as from the same camera and lens ...... and any minor differences as normal shot to shot variation.  :rolleyes:

 

on the full size images the SL is significantly different and looks more 'life like' ...... but I feel that is almost entirely down to the smooth way it renders the OOF areas and transitions ......

The last four from yesterday. The objects in the SL pictures have depth IMO. Slightly different angle for the 5DS R with the Otus in the first one but, still, the engine looks three dimensional in the SL picture also in the front part to my eyes. Again, AWB by the cameras. Tint is +28 for the SL Engine and +16 for the Canon one. I left it as it is. SL pictures opened in LR and Vignetting corrected +30, otherwise not touched. Canon opened in LR, lens profiles applied, Exposure -0.35 for the Engine and -0.20 for the Showroom to try to match.

I have more from today  :)

 

Engine ISO 200, f/1.4, 1/80sec for both. Showroom ISO 200, f/1.4, 1/160sec for both.
