Added the current 50 FLE I in my comparison image. So 35MM FLE II, 50mm FLE II, 50MM FLE I. The new lens will weigh noticeably more.

I will thus call my 50 mm Summilux ASPH the „slim Summilux“ from now on… 😉

Well, I am not going to presume that the lens(es) in the leaked images is the final product, but, the lack of ribs or grooves on the focusing ring would be a significant minus, in my consideration of acquiring this lens.

Thanks for pointing that out. I tend to use the grooves to focus the lens precisely with live view at f1.4. I would definitely miss those too.

Good point. I rarely use the tab and would also miss those.

I use a combo of the tab and the grooves... Considering how moody the "old" 50Lux ASPH can be... Never could manage to ONLY use the tab. But if the new one has wider girth and is easier to turn just by the tab... maybe we don't need the grooves? 
Still sucks for those not using the tab at all...

the grooves is around the focusing tab (just like the 35FLE2)

If all focus tabs, on all Leica M lenses, had positions that corresponded to the same distances, the tabs would be more useful for setting the distance by feel. The tab positions on my Elmarit-M 28mm Version III, Elmar-M 24mm ASPH, and Summilux-M 50mm ASPH do not correspond to the same distances. The Elmarit and Elmar are reasonably close enough, but the Summilux is not close, and with its shallower DOF, that is significant. I have tended to use the ribs/grooves, when focusing my Summilux 50. This Summilux was the lens that lured me into adding the Leica M system, five years ago, and formed my concept of what an M lens “should” be. 

I do find a tab to be important on a small lens, such as my Elmar-M 24mm ASPH, on which the rings are so close together that one might inadvertently change the position of the aperture ring while gripping and moving the focusing ring. 

I have recently been working with my APO Summicron-M 75mm ASPH, and dabbling with my Thambar-M 90mm, which are relatively large lenses, with no focusing tabs, and ribbed/grooved focusing rings. My most-used M-mount lens, the Zeiss Distagon 35mm f/1.4 ZM, has a ribbed/grooved focusing ring, with a small integral nubbin, rather than a tab.

To be clear, this post is not meant to have a negative tone. This is not a rant. Life is good; this is a beautiful day. 🙂 I can hope/dream that Leica makes a Special Edition Summilux-M 50mm ASPH II, with a focusing ring styled in the manner of the Black Chrome E43 Summilux-M 50mm ASPH or Noctilux 50mm f/1.2. 😉 Life can be beautiful.

If there are ribs/grooves, on the focusing ring of the final product, that would, indeed, be wonderful. 🙂

You mean the ribs/grooves are ON the focusing tab, just like the 35FLE2?

yupp Marcyokay, the groove is only on the focus tab on my 35FLE2. so sorry, i think i remember there are some groove in the focus ring... but after looking closely there are no groove in the focus ring (in my 35FLE2).  The 50lux2 will have the same design with 35FLE2. im sorry.

I think the lack of focus ring grooves is a significant issue -- the tab is great for the 90 degrees turn from infinity to 0.7m, but the next 80 -odd degrees of turn will require handling of the ring.

Unless your fingers can double in length and loop around over the top of the lens ...  like Stretch McGillicuddy .... in which case you can use the tab for the full range!

That's a pity. I hate focus tabs. On the current version, it's still possible to hold around the focus ring and use it almost as if it doesn't have a tab. Without the grooves, this would be very difficult. Fortunately, I still have my 50 Lux pre-ASPH without a tab. And if I want a modern version, it will probably be the Black Chrome edition again, with its beautiful scalloped focus ring.

I really wonder why they would change this design? My 50 ASPH is one of my most used lenses. It's so dual purpose with grooves + a tab. I mostly use it at F1.4 (grooves + live view) and F5.6 - F8 (tab + rangefinder) depending on what I'm doing.

I think it was the 35 apo which got the groove on the focus barrel

Yes, according to the data sheet published by Leica the new one is 59.3mm long, while the older one is 52.5mm - though I shouldn't be so sure about this, since the people at Leica have a very strong habit to measure their items always in different ways (hood extended or not, etc.). So as long as nobody has seen both next to each others guessing is still allowed. The new one is described in the datasheet as not being heavier:  337g to 335g.

So to call it "Fattilux" compared to the "Slimmilux" would not be very kind...

I saw some "pre reviews" make the mention that the optical design being different didn't change the quality at all on this lens. I thought I'd look at the MTF charts, and you can see some interesting differences in the detail. Most interestingly is that the lens is far improved in the center, but actually a little "worse" midframe. All of it is minor, but it seems like they have very much decided to focus on getting portraits to be as crisp as possible. What's also interesting is that this lens is *almost* as good as the 50APO on the MTF charts except way out in the corners. I decided to go on a couple of waiting lists for this, personally, as I think it will be a really nice addition especially for nighttime and portraits.
