Summilux-SL 50 MM F/1,4 ASPH

I was a bit surprised to read in LFI (page 57) that the Summilux-SL 50 MM F/1,4 ASPH will come without stabilizer. 

 

I was expecting all the SL lenses to offer IS as there is no IBIS. 

 

Maybe it is necessary in order to make sure it will be the best 50/1,4.

Re: stabilization.  When a group of elements is made to move for stabilization there must be trade offs with centering.   I have asked knowledgeable people and have yet to get a response substantiating or refuting this, perhaps someone here can shed some light.

Well, it is a matter of  choice,

1/Do I want at F1.4 a "stable" view of the blurred background ( a bokeh) stabilized by compromised optic system taking care of my shaking hands

2/ do I want at F 1.4 to "stop action" , getting the sharper image of the subject using same lens ( stabilization shut off).

3/ do I want a superior optics  operating as  2/.(Above).

4/ do I want a best performing lens , no compromises operating as in 2/.

 

If I had the money , I would choose  50mmF2 with stabilization and 50mmF1.4, or faster with best optics possible to have a choice  for  the  two different shots..

No lens maker will ever admit that IS seriously affects IQ, even when turned off. Well, Canon somewhat did years ago, regarding the 70-200/2.8 L. I would have never expected Leica to do that, but they surprised me, luckily on the zooms, that I am never going to buy. I'm very happy there is none in the 50, because I do plan to get one. In terms of lens design, I have utmost respect for Zeiss. They have principles and they follow them. Too bad they don't make cameras.

I'm very interested in how this lens performs.

 

I'm planning on using the Noct with the SL, but if this new Summilux is any good, I can see it joining the fold. Having the Summitar, Summilux and Noctilus in M mount, I seem to have a bit of a thing for 50s.

John,

 

The word from Leica is that the 50mm SL Summilux is the best 50mm Summilux made to date.

Since it is being made specifically for the SL, and its AF I would think its a must have for the new camera.

I currently own both the Summilux and Noctilux and you can bet I'll be first in line for this new Summilux.

Please stay right behind me :)

For the size, it needs to be an Otus beater.

 

 

By what measure?

 

Some believe the APO 50 is better than the Otus; and how will you tell?  I guess you could offer a "definitive" answer if your photography was entirely conducted bench testing. 

 

For me, if the lens works with the camera (you'd need a Novoflex adapter - I don't see Leica or Zeiss making an adapter), then that's all I really need. The Otus is huge, and manual focus, where the Summilux looks huge and will (apparently) be autofocus. Is that a useful comparison?

 

Price, weight, length and diameter can be measured - not sure at this quality level there is any other accurate or useful measure.  One might feel better in the hand than the other, or give more pleasing results to you ... I'm happy both make my Noctilux look compact!

For fast lenses the main issue is eliminating aberrations wide open.  It's good if the lens is sharp wide open, too. Character (as with the existing Summilux M, or the 58mm Nikkor, eg) is a bonus.   All of these lenses are more compact that the prospective lens. So the extra bulk needs to buy us something.

Zeiss still maintains as of today that their Otus 1.4/55mm is the best standard lens in the world. If it is better than the 2/50 APO, I don`t know. It cerainly is many times larger.

To me, "Best Lens" is a tricky concept - tough to define, even tougher to prove... I.e, to me the Noctilux f/1 is a great lens, the only M lens that I haven't ever sold, and produces my favourite look in a 50mm to date; is it the best 50mm, then? I don't think so, if you look at MFT, check sharpness, vignetting, aberrations or the like. But - is it the best 50mm for me? Very likely, so far at least :)

 

I am sure the new Summilux will be an amazing lens, technically. If it also draws in a beautiful way, I'll probably get one. Whether it is "Best", or better than the Otus, the Summicron APO, or than this or that lens, it's relatively uninteresting to me: in the end, the way it draws is what really counts...

 

Just my .02 of course. Best,

I consider the "weakest link in the chain" as the critical element.

 

Astonishing how much emphasis is put on "having the best lens". Usually without clearly defining what is the optimum.

For getting the "best results" other factors are much more critical, because they are further away from being optimal.

And it is typical that the weakest link is a moving target - as soon as one is improved another one takes readily its place.

But I think for the last few decades the lenses (at least primes) never were the weakest link.

 

The existing lenses are already close enough to perfection. If lab tests show a new stellar performer, this will not make a big difference as most users here will not be using the lens in exactly the same way it was tested. The advent of Art lenses and Otus lenses did not leave an impact on me, did it on you ?
