They changed a few things but making the lens go to 0.7m would've been awesome and perhaps a reason for me to switch from my v2.

Maybe there's still an opportunity here for Light Lens Lab to release their own 35 Lux pre-ASPH replica? With the 35 Cron v1 replica they made some modifications to the non-optical side of the original's design, including 70cm MFD.

Back during the 35 Cron replica development my vote for their next project was the 35 Lux pre-ASPH...

The way the in focus parts pop away from the out of focus region is a definitely a unique look. Love the way that looks, but also schizophrenic in some circumstances. That veil is also too much for me. Definitely screams 1960s fast lens

I can't speak to this directly, but if you (or someone here) has the "50 Years Leica" book, it would probably specify that. And I highly suspect that v1 does use different glass, though how meaningful the difference is might be more on a confirmation bias/placebo.

The same thing happened with v1 versus v2-4 of the Noct 50/1. And that book does state v1 uses different glass than later Noct versions.

I did a little research on this and indeed the glass type in 3 elements were changed from the original steel rim. Probably due to environment requirements. (This is unknown)
It looks like the new glass is made of Lanthanum (N-LAF21)
https://www.us.schott.com/shop/advanced-optics/en/Optical-Glass/N-LAF21/c/glass-N-LAF21

To quote from a paper on this lens by Elcan lens designers: "Typical of older designs, the selected double Gauss lenses we have analysed contain obsolete glass. We have briefly reviewed the implications of manufacture with currently available glass types. Considering the 35mm f/1.4 Summilux. LaF21 replaced three elements, marked as ‘LeT29’ in the original design, at some point. We have been unable to clearly identify the latter. It appears that this simple double Gauss form cannot give improved performance given the field and aperture constraints even with additional glass choices."

Because of this, it's likely the re-issued version (v3) will perform closer to the v2 instead of v1 since the glass used on the latter has been obsolete for many decades. Having said that I'm convinced the differences will be subtle at best. I will probably purchased the v3 to compare to my v2 (1978). It could be a good comparison because my copy is well-calibrated with the RF, is free of haze and it's centered.

yeah, that makes sense and it’s similar finding from official Leica documentation, but the link I drew it from has expired. I cannot do research right now as I am busy, but I’d be curious to see if the Noct v1 and Lux v1 (and the Leica lens catalogue generally) all used older glass elements at that time. I am assuming that Noct + Lux v1’s were manufactured and then altered contemporaneously.

Not the case with my copy of the v2. Extremely consistent at f/1.4 with very sharp point of focus but with some glow. Veiling flare, however, is prominent, but the lens can be shaded to avoid it. The effects of internal reflections of the lens at f/1.4 are strong when shooting into the sun (as illustrated in the video):

I own the collapsable version of their 35mm 8-element, and it close focuses to 0.5m and has an infinity lock. A 0.5m or 0.7m version of the pre-ASPH would be incredible. But I've moved to shooting M lenses on the SL2-S with a macro adapter anyway, so it's a bit of a moot point for me at the moment. But I can say the v2 at f/1.4 at macro distances on the SL2-S performs very well, and the performance at macro distances to 0.7m is similar to how it performs at 1m.

Thanks for your observations. As an aside, have you compared the technical quality of your M lenses on the SL2-S vs. the Canon R5, if you still have one? I realize there's a sensor resolution difference but I'm wondering if there's much difference in noticeable edge detail smearing between the two? For example, landscape type shots with the focus at a farther distance where edge smearing becomes more noticeable and would indicate that one (the assumption being the SL2-S) has a sensor cover glass thickness better optimized for adapted M lenses.

I am very curious about this as well. The rumored R6ii, which should be out very soon, uses a BSI sensor that should help with typical RF lens problems. And I think I recall reading Canon’s sensor glass is thinner than Sony’s but can’t remember how much.

I like Canon’s grip, ergo, EVF’s and the sensor on that body is fantastic

At first I was getting very poor results on the R5 with M lenses, until later I tried a macro adapter. With the macro adapter, I was able to set perfect infinity focus at the hard stop wide open before I started shooting each time. This greatly increased the off-center and corner performance of my M lenses on the R5. With the macro adapter, I'd say the performance of lenses like the 28 Lux were close to that of my SL2-S, which is pretty impressive considering the R5 FSI sensor and thicker cover glass. I also was getting good results with the CV 50 APO and the macro adapter on the R5, but I never got to go back and test the 50 Lux (latest) since I'd sold it by then.

I'm in the same boat, as I only have the Leica Q2 at the moment. I'm currently weighing going back to the SL2-S (Reporter) versus just going back to the R5/R6 or even the R3 with its BSI sensor. For me, the R5/6/3 advantage is access to lenses like the RF 100-500 over say the stupidly-expensive Leica 90-280 or the Sigma Sports 150-600.

Also have been considering going back to the GFX 100S and adapting my Contax C/Y and Minolta lenses over M lenses.

I'm still not transitioned to mirrorless and this is one reason I'm a bit hesitant to get one of the R5 or R6 bodies right now; at two years they're now in that 'soon to be replaced' zone of uncertainty. Though yes, it doesn't mean they'll suddenly perform worse once their replacements are out. I've been using the R6 for the past few weeks (in addition to trials of the R3 and R5) and while it has certain performance advantages, primarily AF precision and consistency, over DSLRs, it's a bit too stripped down IMO compared to the R5. My biggest beef with it is actually its EVF. It's grainy in comparison to the R5's and seems to have limited dynamic/tonality range too. In really bright sunny conditions, EVF image quality is too high contrast. I liked the R5 better but feel that at this point, two years since release, it's a bit too much of a first-gen feeling product that definitely has areas where improvements can and likely will be made in the Mark II version.

If the R6II gets a higher quality EVF in addition to a faster scanning BSI (or as also rumored, stacked) sensor, I would be very tempted. I wouldn't mind if Canon shifted it somewhat upmarket and brought in an R8 or something to fill the stripped down, lower price point range.

Thanks for the additional info. Which adapter are you using? Over the past month I've borrowed from CPS the R3, 5 and 6. Unfortunately I didn't get around to trying any of my M lenses on the R3, but I did a basic tilted infinity test with many of them on the R5. I just haven't gotten around to looking at them closely. I bought a cheap Urth adapter and typical of most fixed adapters, it's slightly too short. Correct infinity focus is generally short of the infinity hard stop on most lenses. So I'm a bit reluctant to share the results because they could probably be improved. In any case, I didn't see any obvious edge color shift with any of my lenses on the R5. Many of them however showed edge detail smearing/astigmatism that generally needed f/5.6 or more to clear up. I have to say I really like the small M lenses on these mirrorless cameras. Combined with IBIS makes for really great hand-held versatility.

Agree on the R5/6 comments. At one point, I had moved from the R5 to the R6, but the R6 EVF drove me back to the R5. But yes, it's hard to buy any FSI sensor camera given everyone else is using BSI. Shadow retention is good on FSI cameras like the R5 and GFX 50 variants, but the shadow color integrity when lifted is so much better on the BSI sensor cameras I've tried like the SL2-S, M11, and GFX 100S. I guess I really like Sony sensors in non-Sony bodies

I think my macro adapter for M to RF is Kipon. My macro adapter for M to L is Hawk's Factory. Unfortunately, no one that I know of makes a macro adapter for M to G for the GFX, and even Novoflex's adapter is much too short to be usable for M lenses, IMO. The Novoflex would need shimming to be useful for me, and that's a bit beyond my technical/mechanical skill level.

The round hood screws into the lens or filter. The replica OLLUX hood is bayonet mount like the Voigtlander hoods, but I'm not sure if you can use it with a filter. I thought I remembered reading a reviewer say you can't, but we have to remember the initial testers were using prototypes.

Not that it helps see about the filter issue, but for fun here's a good photo of the production lens and both hoods:

I found the answer on Jonathan's review:
https://gmpphoto.blogspot.com/2022/10/leica-35mm-f14-summilux-v1-steel-rim.html

"It comes with 2 different lens hoods; The original Ollux remade, and a round screw in hood. Leica have retained the 'fall off' characteristics of the original Ollux, so the screw in shade is very welcome! Unlike the original lens the remake has a 46mm screw thread for attaching filters, the round shade screws into this, and retains a thread inside, so you can attach filters with either shade (or with no shade)."

I saw that—very welcome. I hate the filter system on the OG. Funny they fixed this but left the long MFD.

I do wonder is this new hood is backwards compatible with the OG Lux.

Yeah, I would like to use the collapsible 70-200/4. The only 2 native Sony lenses I use are the 24 GM and Sigma 35i. So a tricky replacement for AF lenses on the Canon front, but for an m-platform that does better (though not native) performance-wise than stock Sony is attractive to me.

I revisit buying a GFX body again, but I really would prefer the lens catalogue of the Hasselblad—that new 38mm is fantastic for me. It’s the 31 limited FL—in my opinion the best FL is a wide 35mm or narrow 28mm. Sadly, the focal plane shiite kills lens Adaptability.

@rscheffler I have actually not shot the MILC Canon bodies much, just trial them in the store. I used to shoot the 5dii way back in the day, and owned the 85/1.2/70-200/4 in multiple iterations among other Canon glass.

Hopefully the EVF is better in the new R6ii. I know what you mean about a bad EVF ruining the experience. That is my main gripe with a 7C. It’s so annoying.

And yes—Sony sensors are king in my opinion as well. Especially in non-Sony bodies lol.
