Hi everybody,
Before I ask anything - yes I am fully aware that same question must have been covered so far ( probably many times ), but it's kinda difficult to read all those 585 pages to find all the answers, right...? 
It's about "right" 50mm lens. Here's the story: I have possibility to buy brand new 50 Lux-asph - no waiting time at all - my camera dealer has it on the stock! My wife told me I was out of my mind willing to pay that amount of money for one lens, but it seems that she has accepted it now...
But...
I didn't have chance to shoot lux myself yet ( I read really a lot about it though ) - I expect to do it tomorrow. But during the last several days I had opportunity to test latest 50 Summicron - and...I like it very much! It is insanely sharp from wide open ( a lot of people say it is sharper @f2 then Summilux! well, that might not be the truth, but I can hardly imagine a lens that can be sharper! ).
So now, even I got a green light from my wife to buy Lux - I am thinking if that really would be a good idea or I would be better of buying a Cron...? And use spare money on 24mm Leica or 25 Zeiss ( I have idea to shoot Leica with only 2 lenses 24/25mm & 50mm )
Surely I get one extra stop with Lux( 1.4 vs. 2 ) and creamier bokeh, but is it worth the money? Specially if Cron really is sharper...? What do you say? What are your experiences and thoughts about this?
Thank you very much!
At the end a couple of random photos taken with Cron - all of them wide open:

Nice samples, you will be just fine with 50cron 
I can feel your pain Hopeful there is more people visit this thread and have used several 50mm lens to give you’re an idea. Why not try to bring this question to outside of this thread? Or even other forum like GETDPI or LUF? You might get a lot more opinion than here.
Anyway, here is my take: at WO, it is sharp and might be the sharpest 1.4 lens. Is that really important? Not to me, unless you shoot 1.4 landscape like KR did or some flat painting. A lot of 1.4 lens will give you very close performance to it and cost significant small fortune. For landscape, it definitely sharp enough for me, but overall, I am not that impressed with its slow down performance. At f2, it doesn’t improve much compare to f1.4, might because of 1.4 is already pretty good. (I feel MP50 has better optical at f2 for most of the frame.) So I think if you don’t need use it a lot at f1.4, the summicron is a better bet to you for the performance and price.
Its CA control is very good almost to the APO level, which is a good thing. Contrast slow down is very high. Bokeh is very smooth if you after that.
I don’t like its handling, the pull out hood feel cheap. But that is just personal opinion. You know some lens you will just instantly like it,(say, ZF351.4, P50, P85 and 50luxR ) some just not, this case is 50lux. I should say a big part of the reason I never really like it is I have very high expectation for it. And I think it is overpriced. I feel its reputation has something to do Puts review, a leica bible.
Please don’t feel offended if you are 50lux owner as well all is just my feeling.
As for other 50mm lens, I just write something in previous pg about Sonnar, it pretty sharp WO and meet my requirement for portrait. F2.8 it is already very sharp lens. F5.6 only corner still lag a bit.
I also enjoy use 50cron Rigid, small, light with high build quality, most important can be have around $1000. Slow down, it is close to 50lux, it is not as sharp as 50lux until f4.
A lot people (Edward) also use ZM lens like planar, it should be close or as good to summicron for much less price. However, other than performance, you also happen to care about build and handling, you might want choose Leica and forget about other brand.
I like to use f2 lens for rangefinder system, it is a lot less fussy about focusing. (I have to send my 50lux to Leica to have it perform as is)
Will I sell 50lux? Probably not, as it is does nothing wrong. And it is a good tool for anything I can think of. Will I buy it at full price again now with the knowledge I have, no I guess. At least not for the full price. $3000 I will go for it.
Enough said. Hope it helps.
