not like i'm gonna buy either but i'm curious, besides the maximum speed and i assume size - what is/are the differences?

i assume the summilux is more expensive generally?
 
The difference is in your pocket, about 1500.00$ :)

But I'm assume somebody here will give you the complete technical spec with the glass recipe...
 
E. Putts says the Summicron is a masterpiece lens. The Lux is not. Also, the Lux is a humongous lens in size and weight-- not given to walkabouts unless you want to be hunched sideways.

You can save about $3K (USD) by getting a 75mm VC which is very good. You can split the savings with me.
 
The Summicron is harder to Find
EASIER to Shoot with
Modern SHARP with a very overall edge to edge Creamy Dropoff
used prices generally around 2800.00

Summilux quite Sharp but way more Rounded...Lush blacks...gentler so to speak

The summilux 75 is a large lens, but it is much lighter and smaller than most SLR kit lens, especially from the slr lens made in Japan era.

I walk around with mine everywhere, and have used it with out strap for all day use at events.

The Summicrons are great lens, but they don't have custom made glass like the Noctilux. The lux also focus close - 0.75m is close enough for anything I've ever needed, and closer than both my 35, and 50 luxes.

The lux is a fine lens, and if you like to take fine art photos, this is the lens you should get.

The cron is just a lens. If you just take photos, then the cron might be fine ;)

The 75mm Summilux is reputed to have the best bokeh of all M lenses, and the best for portraiture.

PS. I had this lens twice, but didn't use it much, because during my film days I had too many out-of-focus shots.

Well, there you go. Competence issue.

Now that I'm digital, I would buy it again if I had the budget for it.

IOW, you speak from hearsay and have no competent personal experience with the lens. How can we take such a post seriously?

I'd enjoy seeing a direct comparison of some portrait lenses using the same image...

The bokeh I've seen from the 75 1.4, sometimes reminds me of the wonderful bokeh I get from my Nikkor 105 f/2.5, my Leica 90 f/2 and my Zeiss 150 f/2.8 (MF)...

Being the 105 such a common lens and one that's owned by lots of members ($200) and the same for the v2 Summicron 90 ($300), it would be interesting to see a same image bokeh comparison... I bought those lenses precisely because of their bokeh and general very relaxing portraiture rendering... I'd like to see how in real shots of the same image those lenses' bokeh differ... Maybe a forum member could be as kind as to share a test...

Cheers,

Juan
 
I also would like to see such a comparison including the Summitar and CV 75mm as well.

The MTF suggests that the Summicron 75 is a muchness with its 90mm sib. Not surprising. The Lux is sui generis.

The ability to learn things from other people, without firsthand experience, is powerful. It is so powerful that it explains the origins of language and writing. I suggest that you take advantage of these tools in a more positive way.

I cannot speak for the selling prices, but the Summicron is generally advertised for higher prices than the Summilux. Contrary to what others have said, the filter size for the Summicron is 49mm. The Summilux imparts the classic Walter Mandler signature, while the Summicron imparts the classic Peter Karbe signature.
 
Being able to focus to 0.75m with the Summilux 75 would make it a very nice, working lens. One of my pet peeves with some many rangefinder lenses is that the minimum focusing distance is around 1m. I keep a Nikon F slung over my other shoulder just for this reason, since even early Nikkor 35's and 50's will focus down to 0.5m with ease.

I use the Nokton 50/1.1 regularly, how does finder obstruction compare with the Summilux 75... or I should say frame-line obstruction.

I believe that Roland aka 'ferider' used a Summilux 75 extensively over the past year or so. Would enjoy hearing his experience.

Thanks!
 
They are at the same price range though the summicron price is going up lately.

75 cron is definitely sharper. I also tested cv 75 against 75 summilux. The CV 75 is sharper. The 75mm summilux is a special lens like everyone said. People love its speed and signature.
 
Sharpness is not the only factor that is important to me in such a lens.
Having a Nikkor 105/2.5 and a Summicron 90/2 is enough for me. The 75/1.5 Lux is icing on the cake.
 
do you have some side by side comparisons?

do you have some side by side comparisons?

Many folks don't have their 75/1.4s focused right - not that you don't have it in focus in your VF, but the lens itself may not be focused. I have the MTF's from Leica for both the 75 lux and 75 cron, and these don't show less resolution at most apertures, certainly not at 1.4 ... ;)

Here's an interesting mini-review of the lux from a site that usually only reviews current production newer lenses:
