Well, I'll be hornswaggled!

 

The US press release says the same thing we'd already read about!

 

 

Only a 32% increase in weight, and 3 mm more girth. Looks like exactly what LFI said a year or so back (paraphrasing), "If we were designing it today, we'd give it a floating element."

 

Very impressive IMHO, that apparently the previous version didn't need major redesign. Looks as if this lens is just the same except for the floating element, as has been said before.

 

And only $500 more than its predecessor. :)

 

Looks like a winner, no?

 

I want to see the technical brochure and MTF curves!

...(my typo above sorry)

Not 100% sure though. I have 2 different 'Technical data' of the 'old' 35/1.4 asph. The current one (link above) says 320g but a previous one said: 'approx. 250 g / 415 g (black anodized- / silver chrome finish)'.

So, what exactly does this lens give me on the M9 that the following don't

 

- pre aspherical (Canadian) Summilux 35 (black in my case)

- Aspherical Summicron 35 (chrome in my case)

- Voigtlander 35/1.2

 

I think the Cron has the colour rendition and contrast, the old Lux has the speed and lightness and the VC 35/1.2 has the extra stop if needed. Or should I trade them all in for the one lens?

Performance. Really, the new version is almost certainly so superior to these lenses on a purely technical basis (please don't overlook this disclaimer) as to render any comparison moot. No one will be comparing performance; they will be comparing look.

 

- Aspherical Summicron 35 (chrome in my case)

 

I presume you mean ASPH. and not Aspherical. It will have f/1.4. Other than that, I expect the performance to be similar.

 

I have the 35 Lux Asph, also chrome, and this comparison is the most interesting, I think. It sounds like the new one will be sharper, but the main improvement is almost certainly to eliminate the focus shift so common in the old design. Of course, I am fortunate enough to have a copy which has almost no trace of this, so I will just keep being happy with mine. In fact, I like the slight traces of Mandler-era softness-over-sharpness wide open, so there is another reason to keep the old version.

 

Further Disclaimer: Not everyone likes the sharp new lenses, so there will always be people who prefer the pre-Asph, the Nokton or the (now) old 35 Lux Asph, of course. We all choose our poison.

Hi

 

If they have addressed the flare in the 'current' ASPH, then trade them all in borrow some more and get the new lux.

If they have not fixed the flare sell the Leica lenses and get a f/2.5 & f/1.7 CV.

The MTF data (at 1.4, 2.8, 5.6), as well as the distortion look identical to the "old" one.

 

What puzzled me what the fact that there was no improvement at 2.8 over the old one, as the focus shift (that was worst at this aperture) should be gone.

 

Of course, some "real life" samples will decide if this is really an improvement over the old one

... Leica continue to redefine the word "inflation". In 2006, less than 4 years ago, I paid £1379 for my existing 35mm Summilux.

 

For floating elements, one floats a loan. ;)

 

 

 

And anyway, Mark, IIRC yours is of the oldest design that didn't have the extreme focus shift they've now corrected in the new one. :p

I think there is no increase in weight. I have seen several times the current one listed at 250 grams but it is not correct, it already weights around 310grs (black)....

Thanks for the correction, yani!

 

That extra 30% in weight could have been used to explain the price adjustment. :(

MTF graphs refer to best focus -- i.e., with refocusing for each aperture tested, in the case of measured MTF. The graphs we see, unless they refer to quite old lenses, are all computed data a.f.a.i.k. So in neither case does focus shift appear -- one of the really weak points of MTF data as we know them.

 

If a lens was actually measured on the test rig, adjusted for best focus wide open, and then tested stopped down without any subsequent adjustment, we would have seen focus shift all right!

Oh well at least this helps me refrain from a GAS attack. My 35 asph chrome has such minimal focus shift in practice that I would only have considered upgrading if the new was was smaller, noticeably better and silver :)
