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.

I have both the Otus 55, and the Summicron 50 Apo. I like them both, and wouldn't say one is 'better' than the other - They are great, but different.

 

As stated by others, it depends on what you are using it for, and what you want from it. For some, the AF is very important, in which case the SL Summilux will serve significantly better than any non-AF offering.

I agree with Vieri that the way that the lens draws is important, although I am less concerned than some about the roundness of bokeh highlights.  Also important is the absence of aberrations (particularly for night shooting, or photos that have abrupt brightness transitions).  The 50mm M APO Summicron produces superb clean images, eg.  WIth the high performance of the SL zooms, I will probably enjoy the compactness of the M lenses combined with them, and wait until Leica produce some lenses that allow me to do things that I can't with that combination (eg, macro, PC).

AF is nice to have. On the other hand, at least one Chinese forum already mentioned that Techart is now working on AF adapter for M to SL mount (similarly to M to E mount for Sony). If this is the case, I hope that the new 50 Lux will offer a bit more than M Lux and 50/2 apo to make it more attractive.

After acquiring both 24mm-90mm & 90mm-280mm VE zooms for my SL, I have no attraction to the coming SL LUX 50mm. Rather I can't wait getting my hands on a set of the Techart LEM / SL AF adaptor to get both my Noctilux to work on my SL after hearing how successfully the Techart AF adapter worked on the Sony A7.

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 ?

 

Personally, I find that I am the weakest link.

After acquiring both 24mm-90mm & 90mm-280mm VE zooms for my SL, I have no attraction to the coming SL LUX 50mm. Rather I can't wait getting my hands on a set of the Techart LEM / SL AF adaptor to get both my Noctilux to work on my SL after hearing how successfully the Techart AF adapter worked on the Sony A7.

 

I can see why but I'm coming from the opposite direction. Having seen how well the zooms work I'm more interested in the 50mm than ever. Originally I bought the SL to use my M lenses and a flash at the same time. I didn't get the 24-90 straight away. When I did get it I wondered why I waited so long. In the end I have disposed of some other cameras that I was using when I needed AF and the SL has become my primary AF system already. When I use my Noctilux I expect manual focus and I don't feel it's slower than I need. And I've almost stopped using any of my other M lenses on the SL. Now when I'm adapting lenses they're specialised, like the Noctilux and TSE lenses

 

What I'm finding, for me, is that the SL has a split personality. There are days when I use it as a camera that accepts adapted manual focus lenses and there are days where it's a great versatile AF camera. In the second situation I only *need* two more lenses and one of those is a great 50mm. Mind you, I'm looking at this from the perspective of a working photographer, not necessarily a casual shooter where I would more than likely carry my M or XPro2.

 

I'm keeping my Noctilux for the SL for those times it sings. I expect that the new Summilux will be a very different lens to the Noctilux, which for me is a specialised lens. I've already decided to sell my M Summilux and replace that with the SL Summilux. I already have the Noctilux and a CV 50mm (which I really like) for my remaining M camera. So it's not like I'm short of a 50...

So, what sort of rendering can we expect from this lens? I suppose it's going to be sharp and contrasty, nice colours and good acutance, but bokeh remains to be seen. What do you guys hope for?

That it looks good? :-)

I don't know of a metric for bokeh or other rendering qualities.

If it follows the 50/2 apo ......... NONE.

 

The whole point of a 'perfect' lens is that it adds nothing and takes away nothing ....... just sticks what it sees on the sensor with as little optical error as possible and at a resolution that comfortably exceeds that of the recording medium. 

 

That is what Leica mean by their 'best 50mm lens to date'.

Agreed.  The point about bokeh is that it should not draw attention to itself.

 

Aspects of rendering that lens designers will consider beyond that are how fast sharpness / contrast falls off from the point of focus (very, with the APO 50mm), how points of light are rendered (ideally as points).

Edward - I don't find this at all.

 

I have Nikon and Fuji IS lenses and find that performance is identical with IS on or off.

 

What I do find is, especially with Fuji XT lenses that the IS is superb in allowing handheld pictures at crazy slow shutter speeds with Nikon being OK but not as effective.

 

 

The difference is not so much in if you turn it on or off, but in fact if the lens HAS IS or HAS NO IS.

That is one big-arse piece of glass! And why many of us left DSLRs in the first place.

If this is supposed to set some 'new benchmark for a 50' at that price-point, at whose expense? Otus or their own (tiny) 50 APO?

There was no real world difference between the Canon 70-200 f4L which had IS and non IS versions. So did the first 70-200 2.8L. With the f4, strictly based on measurements the IS version was *slightly* sharper. But in the real world the real difference was that the IS version suffered less from poor technique and handholding. Canon are the only ones I can remember that have had IS and non IS versions side by side and in all cases the only difference was cost.

 

Any optical differences are insignificant compared to the difference IS makes to getting a steady shot with reduced camera shake.
