35mm Summilux ASPH. vd 35mm Summilux ASPHERICAL

It's easier to give full titles than debate acronyms ;)

 

As the other OP thread seems a little hijacked I thought I would start another

 

I didn't have time to set up a tripod, so not an exact comparison but show some differences. Both ISO, both 1/60th, both f1.4 I adjusted both the 3750, the ASPHERICAL chose 4000 on auto. The ASPHERICAL is on top.

 

Two bottles of wine hardly insightful but I can see the slightly different characters even on this example

Me, too, like the bottom version better. The bokeh has a more complete edit around the whole circle. The top version seems to have only half-circle of defined edge. Ideally, I would rather the bokehs have no edge at all and just subtly blend into the background, but a full circle effect is better than a half circle (seems incomplete).

Thank you for this example of both lenses!

 

I appreciate it very much, as one may find many statements about the ASPHERICAL, but never sees any results from this lens. It's one of the "Arlesiennes" among Leica lenses, much talked about but never seen. So your picture is real pioneer's work.

 

I'd support what was already said, though the differences are very subtle. The small lights and reflections in the middle section look smoother on the second imagine, less fuzzy. In the sector from the father distance in the open door at right I see even less differences between both lenses. The scripture on bot bottles seems to be somewhat contrastier on the second example.

 

Could you give cropped examples - perhaps from the oil bottle at left, the sharpest section and the "bokeh" section in the center and right?

 

It's good you didn't say, whether the asph was the "old" one or the new version "FLE." This leaves some room for guessing.

Thanks for posting this comparison, IWC.

 

Judging by the out of focus specular highlight discs to the left of the door the Asph is the better corrected of the two for spherical aberration because light distribution is even but in the top image the discs are clearly brighter at the edges. This is perhaps not surprising since the Aspherical lens has two hand-ground aspherical elements so the correction is likely to be affected by the cumulative effect of tiny errors in either of the ground surfaces.

The relative softness of the aspherical on edges looks more obvious than bokeh difference IMO but i'm on a laptop here so i may be wrong. BTW, at this level of pixel peeping, might i suggest to use a tripod?

Interesting responses.

 

The two lenses I am comparing are the 35mm Summilux ASPHERICAL 11873 and the 35mm ASPH. 11874

 

Yes the ASPHERICAL is 'looser' with a little more movement in the bokeh, The ASPH. is a little more polite, smoother and more polished.

 

Here are a few more that show how the bokeh renders for the ASPHERICAL, for me I think it's wonderful, it somehow adds a little life/movement to the image without being harsh or too distracting.

 

What you won't see is the more 3D in how it renders on such small compressed images, it does have superb image depth.The notes I made on the previous threads cover my observations so far. I will provides some comparisons on a tripod. A few pictures from last night and one from my cafe of the owner, you will note the Bokeh has life, but supports and doesnt distract for me. I chose one of the potentially most distracting of the garden

 

I am still really loving this lens all below 35mm Summilux ASPHERICAL f1.4

The comparison is really very interesting, thank you for sharing.

Both lenses have beautiful bokeh. As far as it is possible to judge from a single image, I'd vote for ASPHERICAL. Probably it is not only matter of OOF areas but also of general rendition all over the image field.

Anyway.... I think you are very lucky to own both!!

Very interesting thread, thanks for showing these examples.

 

I find the ASPHERICAL more interestingly pleasing than the ASPH one. I agree that the ASPH bokeh looks smoother, but the ASPHERICAL bokeh adds something to the image (hard to define what) that I find intriguing. It reminds me a little bit of the latest pre-ASPH version of the E46 50mm Summilux.

Er...guys pardon my ignorance but isn't ASPH just ASPHERIC abbreviated so which one of the two is the newer one with the FLE?

Afraid not. The ASPHERICAL was the first version following the pre-asph and the ASPH is the first version following the ASPHERICAL. (Capitals are Leica's not mine.:o) The ASPHERICAL contained two hand-ground aspherical elements but the ASPH contains one machined aspherical element.

 

The FLE (floating lens element) followed the ASPH and is the current ASPH version; the floating elements moves independently of the others to compensate for focussing errors that are inherent in the optical design. I believe none of the pictures in this thread were taken with the FLE.

Nice comparison. It's rare to see results of the Aspherical.

 

I'd, however, go for the Chateau Musar over Labouré-Roi.

I hoped it wouldn't be too pretentious to put two £10 plus bottle of wines in a picture, the trouble is I had run out of everyday plonk and had to go into my special occasions stock ;) They are still both unopened !

 

I prefer the Musar too :D

A plug for the very helpful Leica Wiki

 

Details on the 35mm Summilux ASPHERICAL http://www.l-camera-forum.com/leica-wiki.en/index.php/35mm_f/1.4_Aspherical_Summilux-M

The 35mm Summilux ASPH. http://www.l-camera-forum.com/leica-wiki.en/index.php/35mm_f/1.4_ASPH_Summilux-M

 

Also to help with any confusion a link to the current 35mm Summilux ASPH.FLE http://www.l-camera-forum.com/leica-wiki.en/index.php/35mm_f/1.4_ASPH.fle_Summilux-M which is a lens I do not own and is not yet in this comparison (I may be able to borrow one at some time in the future)
