pico Posted January 2, 2012 Share #21  Posted January 2, 2012 Advertisement (gone after registration) IMHO thats tosh, I have just been out checking over the Weston I bought just before Christmas, comparing it with the M6ttl, Voigtlander VCII on the M3 and with an FM2. [...] Gerry  Oh, for sure you fill find different outcomes! That's why I just hate getting a new meter, of any brand.  Gerry, you probably know this, but for the rest, Weston changed their exposure scale (the wheel) to be a bit more pessimistic at one point, probably to accommodate color films. I'd have to dig through the big box of Westons to find which serial number is in the old range - but I will if you like. (So few of those old Westons work, anyway) Link to post Share on other sites More sharing options...
Advertisement Posted January 2, 2012 Posted January 2, 2012 Hi pico, Take a look here Noctilux T/0.95 competitor...... I'm sure you'll find what you were looking for!

(So few of those old Westons work, anyway)  I've been using Westons for 50 years, I think the change you are talking of was from Weston speeds on the II to ASA on the III, in the 1950s, that was merely a change of film speed system in use, from their own Weston speeds to the standard ASA system, no difference in the actual exposure indicated. It was all complicated by the dubious change in the late 50s to the ASA system when the speeds on the films doubled overnight, 'to remove the safety factor'. Effectively it moved the exposure further down onto the toe of the characteristic curve, compressing the shadow detail.  Gerry Link to post Share on other sites More sharing options...

One would think they would promote such as they did in the first post here. I smell a rat. Â FWIW - For M4/3 the 25mm Voigtlander .95 is stunningly sharp from wide-open to mid-aperture. Of course, it doesn't work on an M. Link to post Share on other sites More sharing options...
billib Posted January 3, 2012 Share #25 Â Posted January 3, 2012 I would think SLR Magic would advertise on this Forum when they are ready with their M mount version. Thats if their lens is competitive, anyway. If its a dog, they'll avoid us like the plague. We'll find out soon enough. Â Maybe we can talk pico into buying one. Yah, he could be our test mule.

TomB_tx Posted January 3, 2012 Share #26 Â Posted January 3, 2012 I notice Steve Huff says they will have the first samples at his workshop at the end of January. So we will no doubt hear then how "superlative" this lens is in his eyes. Link to post Share on other sites More sharing options...

Â I will be attending the workshop, and if I get the chance to shoot with the lens will give my impressions along with sample images. I know at least one other person who will be there with a 0.95 Noctilux, so we should be able to get some good comparison images. Â Stephen Link to post Share on other sites More sharing options...

StephenPatterson Posted January 3, 2012 Share #30 Â Posted January 3, 2012 Let's get back to the fact that the Chinese are copying the Leica look in whatever lens it ends up being. Â Just like the Japanese? My father's Canon IVSB certainly bears a strong resemblance to Leica. Â As for the SLR Magic it remains to be seen if they can deliver a production lens by September, as it takes Leica's supplier longer than that to make and cool a batch of glass for Noctilux lenses. Â Cheers, Stephen Link to post Share on other sites More sharing options...
billib Posted January 4, 2012 Share #31 Â Posted January 4, 2012 Even if they can deliver the lens time wise wouldn't it suffer from focus shift do to it not having any Aspherical lenses in its design. Don't the two older Noctilux lenses suffer from focus shift. Doesn't the 50mm f/1.1 NOKTON suffer from focus shift do to not having Aspherical elements either? Â It looks like the SLR Magic will compete with the similarly priced and spec'd C/V NOKTON. I'm not overly impressed with the NOKTON. What about y'all?

jaapv Posted January 4, 2012 Share #32 Â Posted January 4, 2012 Yes those lenses have focus shift through unresolved spherical aberration, and so will this lens. No big deal as most will buy it to shoot wide open. If they manage to produce it to CV level at thatt price point it will be quite a feat and it will be a direct competitr for Voigtaender,less for Leica. People who are buying Noctiluxes will not be diverted by this lens for the simple reason that it is too cheap to consider. Link to post Share on other sites More sharing options...
billib Posted January 4, 2012 Share #33 Â Posted January 4, 2012 I don't know jaapv, a $1,000 lens with limited focusing success doesn't seem like much of a bargain (to me). That would slowly make me nuts and I'm crazy enough, allready. Link to post Share on other sites More sharing options...
01af Posted January 4, 2012 Share #34  Posted January 4, 2012 ... wouldn't it suffer from focus shift due to it not having any aspherical lenses in its design? Not necessarily. Sure, it will be purely spherical. On the other hand, it will have twelve elements—as opposed to eight elements in the Noctilux-M 50 mm 1:0.95 Asph or seven in the Noctilux-M 50 mm 1:1. In theory, the higher element count can fully compensate for the lack of aspherical elements. And if only the residual spherical aberrations are low enough then there won't be any perceptible focus shift.  However in practice, it's another story. In order to measure up to the Noctilux-M Asph without aspherical elements, it does not only take more elements, it would also take exotic (hence expensive) glasses, a sophisticated design (including floating elements), and extraordinarily meticulous manufacturing to the tiniest tolerances, executed by highly skilled and experienced technicians. If doing all this properly then the resulting product hardly will be any cheaper than a Leica lens. But being cheaper is the whole point of the project. So I'm afraid the new lens is going to be a nice product but not an outstanding one ... similar to, say, the Voigtländer Nokton 50 mm 1:1.1 lens.  In SLR Magic's official press release regarding the announcement of the Hyperprime Cine 50 mm T/0.95 lens, it says, "It is optimized to be shot wide open." This statement might be interpreted as an euphemism for, "Focus shift will render the lens unusable when stopping down." But then, maybe I am just too cynical ...

TomB_tx Posted January 4, 2012 Share #35 Â Posted January 4, 2012 An old rule-of-thumb was that a single aspherical surface could replace two spherical surfaces with equivalent correction. So yes, more elements can be used to minimize focus shift. I see more focus shift in my 69 Summicron than in my 62 - and it has fewer elements (but better contrast). The worst focus shift I've seen is in the VC 50 f2.0 Heliar which only has 5 elements. The Heliar design works very well at f3.5, and is pretty sharp stretched to the 2.0 - but at the expense of focus shift. Link to post Share on other sites More sharing options...
