Light Lens Lab 35mm f/1.4 Aspherical "11873" Review

p.12 #1 · Light Lens Lab 35mm f/1.4 Aspherical "11873" Review


The 35 FLEII which I own, is excellent. Beyond tests.. on actual jobs or my own work, the lens always comes through.
I'm often adding just a touch of diffusion for a hint of more atmosphere. a 1/4 glimmer class, or black satin, etc. But I can take the images in any direction.
Currently I'm testing just how much I can degrade, add character, to FLE files. That will never match the 11873 or 1966.... but what I care about is getting just a bit more filmic look, a bit more atmosphere.. we'll see.
In actual use, The 35 and 50 FLEIIs just come through. From the .4 meter closer focus, the built in lens hoods, the rugged builds.. Though all said.. I own and love the 1966 for its unique character, and will likely purchase the LLL 11873. But if could only own 1.. for me.. it's the FLEII.

Thanks for the review. Now I have more difficult to choose which 35mm to get for my M11. I have always wanted a summilux FLE since you helped me here, but with this one out, the choice is more difficult. The thing is that I'm little worried if the lens broke. The Leica one can be fixed by Leica specialists, but maybe I'm wrong. I think I will still get the FLE. Just because is the one I wanted, but I'm so close to choose this one.

To my eye in the flickr images referred, the Leica 11873 seems much sharper at the point of focus, better micro contrast, just all in all a tighter image. Similarities in bokeh, etc.. but, at least to me.. the Leica 11873 is a different animal.

I have not compared the Light Lens Lab 35mm f/1.4 Aspherical directly against the original Leica version, and without a proper side by side test using the same camera, distance, processing, and sharpening, there is no honest way to say which one is sharper or has higher contrast. I would love to see that comparison if someone owns both lenses.

What I can say with confidence is that the current Leica 35mm f/1.4 Summilux FLE, both the first version and the newer close-focus version, produces higher contrast because it is better corrected for spherical aberration. The tradeoff is that the rendering can look more structured, with stronger edge outlining. From the online samples I've seen, that trait is also present in the original AA and shows up less in the LLL. In some situations you may also notice more purple fringing. Personally, I really like the FLE's output, and it is still my main 35mm f/1.4.

The Light Lens Lab, on the other hand, has unique rendering qualities that give the images a very different mood. I find that I prefer the environment portraits it produces.

As I previous mentioned, it was first and foremost the LLL environmental portraits posted here that really caught my eye, where I thought this lens really shined and reminded me greatly of the Leica 35mm f1.4 pre FLE that I used for many years. In contrast (no pun intended), that's where were I felt the FLE for me personally fell somewhat short and although it excelled in other areas, such as landscapes with its high resolving power, high(er) contrast and other attributes. The LLL seems to have a very good balance of SA without skewing to one side or the other.

As you mentioned Fred, ideally most would love to see a properly done head-to-head comparison of the LLL vs the Leica AA, easier said than done due to the scarce availability of an AA sample to test, unfortunately. A comparison to the Leica pre FLE would be another good one, but I suspect such a comparison would have to be performed on a mirrorless camera such as one of the SL cameras or maybe even better the new M-EV1, due to the pre FLE lens focus shift and also how a given sample is adjusted with regards to it. So far the posted images from the LLL are impressive!

Absolutely, Dan. I'm sure someone will post a comparison soon. If I get my hands on a pre-FLE, I will put together a proper side by side test. In theory, the pre-FLE should produce images very similar to the earlier "AA" because Leica's goal was to maintain similar overall performance and rendering while making production more practical by going from two aspherical elements to one. By that point, aspherical manufacturing had improved enough to make this consistently reliable.

That said, any optical redesign brings subtle changes. The pre-FLE has a reputation for a slightly softer, more gentle look with smoother rendering compared to both the AA and the later FLE.

I'm in the US, and purchased direcrtly from LLL , link https://lightlenslab.com/products/35mm-f-1-4-aspherical-11873
There is also an online retailer "popflash photo" that had inventory, now sold out. Perhaps someone in Europe can futher chime in.

His reviews are getting better.

In the sample photos he compared with the Leica AA it was pretty easy to guess which-witch-is-which (thanks to all of Fred's lovely sample images). The LLL is significantly smoother, with less contrast and resolution at the point-of-focus and has more field curvature. Still, the look it creates is lovely.

P.S. Finally got shipping notice for my copy. Very excited.

Yeah, the reviews are getting better. I like the clearly called out difference in the bokeh balls: LLLs are totally devoid of onion rings, which, from what I've read, speaks to high quality manufacturing. The 11873 exhibits obvious defects (onion rings), by comparison.

I don't really understand the freakout over hood rattling - it's such a simple fix that nearly anyone could cobble together a solution for out of their junk drawer. Nevertheless, a manufacturing fix + optional swap would be nice for those affected.

Some of Fred’s sample photos show a double onion ring / checkered pattern in bokeh balls from light bulbs. I think onion rings are less of a problem when the bokeh balls are from diffuse scenes, side or front lit, and more of a problem from directional light or back lit scenes.

Agreed about the easy fix. Sure, it's a bummer that it rattles, but a few small strips of electrical tape (or something like that) should fix it lickety split.

I am not sure that I will keep mine- I have a steel rim, AA, ASPH pre-FLE, and most recent FLE- my hope had been that the LLL AA would be faithful to the original and would thus allow me a user version- as it is, I don’t see anything I cannot get from my ASPH pre-FLE.

It is a beautiful lens, just not offering what I had hoped for…

Yes, I've noticed the same double onion ring pattern in other reviews of the LLL 35/1.4. To be fair, the original Leica's bokeh inner structure was perhaps even busier. Even the current FLE shows the aspherical molding "onion pattern" when examined closely, as can be seen in my rendering comparisons.

From my perspective, it is rarely distracting in real images. It is only really noticeable in highlights with high contrast and when viewed at 100% magnification.
