35mm 1.4 Summilux pre-asph

Recommended Posts

The Wiki of this forum and some postings say that you cannot use a Leitz Canada 35mm Summilux on a digital M without modification by Leica. 

I think that some of the examples here were taken with Canada versions and I tried one on the M10 - without problems.

So, do the Canadian Summiluxes all work instead of the statements, or only some, or do they all need the modification?

My stock V2 Leitz Canada 35mm Summilux works just fine on M9 and M10. BTW, somewhere there are photos showing exactly what part of the shroud must be shaved ~1mm for non-compliant versions. For some of us it is a simple DIY project.

Oh, my version did 'drag' a tiny bit upon focusing on the M9. User Washington suggested exercising it, and that worked.

Now I got an 3081xxx, which fits without any problems to the M10, but with the M9 you cannot go to infinity, as the lenses shroud touches something in the camera‘s throat.

After all it was a wise decision by Leica to elevate the camera‘s bayonet ring for the M10.

I don’t think they raised the bayonet ring. I think they lowered the body. 

Flange to sensor distance should be the same  but the throat is probably wider.

I like much my 35/1.4 v2 but i would not buy a new one with as much or more optical aberrations. Now a modern 35/1.4 the same size as the pre-asph would have my vote provided it has less coma, less flare and no infinity lock at all (sorry Pico). B)

Oh no, you would take away the defects some of us cherish!

I would eliminate of at least reduce the defects i dislike, namely coma and flare, but i would keep the rest including halos around highlights (aka glow) as far as possible. As for the annoying (to me) infinity lock, i wouldn't have to get rid of it since it has been abandoned on 35/1.4 v2 but i would keep the metal focus tab of v1 if i had the choice. YMMV.

:) Thanks to Leitz/Leica Canada, a lot of V2 35mm Summilux have locking infinity tabs, but we digress.

Finally I got mine, v2.

It is an interesting lens, and difficult to manage at f1.4 though.. Very prone to contra light, it becomes very sharp after f2, as explained here in this topic. It's real character lays on between f1.4 - f2, and you should control and consider a lot of factors in the frame in order to achieve a good result since this is a 35mm focal length. 

Many thanks to the everyone here to help to the people before deciding their lens. 

Cheers..

One last note about this lens:

It produces special glow between f1.4-2.2. Very special romantic environmental portraits can be taken with this lens. But I put a bit more speciality and importance on Summilux-M 75mm f1.4. The Lux75 produces more sophisticated glow at f1.4, even until 2.8. While the 75Lux produces this glow in a more 'latent' form (can be seen in the sharp edges especially), this 35Lux makes it very visible which is very difficult to make it a constituent part of the composition though..

I think there isn't a general rule… my two Canadians (1.765.850 - chrome and 2.290.126 - black) fit fine on M8 and M240, lacking the protruding back shroud which interferes with body : I think it was a manufacturing component which could or could not be inserted, depending on some final QC test… (Canadian factory introduced "new manufacturing methodologies…") ; probably Leica CS still performs the modification on demand… but it can be also a DIY filing job, provided one protects at best the back glass.

This lens could be really great if its minimum focus distance is 70cm! This is the major drawback of this lens for me..

Someone who's good at lens/macro maths should be able to calculate the extra extension needed to get a 35mm from 1m down to 0.7 meters. I'd guess about 0.55 mm.

Most of the 35 Summicrons go to 0.7m, and some of those are as small as the Summilux Pre (including the 'cron v.4, which has the same 7 elements).

Do you think acceptable results could be kept at 0.7m in such a small f/1.4 lens? Just curious.

And near limit isn't only a question about a tighter cropping, as many seem to think. It is also about perspective. Sometimes I want the more dramatic perspective that I only achieve by going closer.

Exactly - attached is with a 35 Summicron v.4 at 0.7 meters. Would not be the same perspective ("point of view") and drama if shot from 1 meter and cropped. Or with a 50mm.

What does "acceptable" mean? For me it means "getting the d*mn picture that says what I want to say."

And it is not just a question of 0.7m vs. 1m framing, but all the intervening distances that are lost with a 1m limit - 0.75m, 0.78m, 0.8m, 0.82m, 0.85m.

I don't buy any lens shorter than 90mm that won't focus down to 0.7m - the limitation gets in my way.

As Leica themselves realized, since they have progressively removed those 0.9-1.0m limitations in most of their 50s and 35s and 75s (and their cameras, post-M3) over the decades.
