  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Leica Vantage Cine Lenses

I know the UK is, but Leicester? Apparently you've yet to meet anyone from there :-)

Worried about being in the EU? Imagine how they feel about being saved by an American :-)
Yep you were way to subtle for me with that joke. Then again my dad is from Birmingham.

I don't understand either of your comments?
 
I'm not sure, but what I think Michael means that the folks from Leicester are more "Brit" than the average Brit.
What John means is that in the early '90s, on the verge of being shuttered by its parent company (Rank plc), Cooke Optics Ltd was saved by Les Zellan, an American (who is one of the owners of the ZGC Corporation) by American funding. I think he's implying that the stiff upper lip might have trembled at the thought of those boorish Americans rushing in with cheap money and saving another venerable British establishment.
Of course, if Les had not done this, the world would never know S4s...
Cheers,

Economically and culturally in the last 30 years UK becomes a country with 3/4 parts like that is 51st US state

and 1/4th part that is like a full EU member country.

Controversy and confusion over UK identity today.

UK destiny in the age of globalization.

Commonwealth becomes for ordinary Brits only as a holiday destination with British style a sort of exotic flavor.

UK core industries were sold out mostly to Americans and Germans.

Banking system is deeply linked to US and EU banking and depends on them.

A real UK money (profit) is deposed in a private Swiss and Bahamas banks and is mostly in hands of rich UK aristocrats,

industrialists and foreign money oligarchs like a wealthy Russians, Arab sheiks and Indian maharajas...

Queen and Royal family trying desperately to keep Brit values even online with websites full of video and photos.

All sound like a big joke but that's almost true.

Thanks Harry

Looks like John and I should take you with us wherever we go with our subtle comment postings :-)

You are spot on mate.

Meant as an observation not a criticism the folks at Cooke factory in Leicester are a proud group who protect and continue tried and true old school craftsmanship and care in the manufacture of each individual S4 lens.
 
Thanks Michael...
Sanjin... you're funny! ;) I do love the Brits though. Good folks.
Harry
 
I didn't say that I do not love or like Brits at all.

There are the facts I found in the press, books and online, also saw and heard even years ago in London and Edinburgh.

Just was trying to get closer to real situation without any illusion about that.
 
Sorry... did not mean to imply that you did not like them.
Just thought the comments were funny, that's all!
Cheers,
Harry
 
The wireform track systems within the Van Dieman housings are unique and , well, terrific. Essentially a pair of coils, one connected to the front and one to the rear with both connected to the lens grouping that moves for focus adjustment. By using wireform tensioners, the rotation movement is always light and easy to turn yet never slips. The lens grouping stays in place when no outside pressure is applied as the wireforms provide all the necessary tensio. And with age the wireforms naturally age together to keep tension equal. Our set is approaching the end of its second decade yet remains in top condition, which is a hell of a lot better than I can say for the wear and tear on the mechanics of other lenses of a similar age.

Thanks for that!

Hi Mitch,
thank you for such a clear and concise explanation,I now understand.
An engineer once tried to explain it to me,and to be honest I was still in the dark.

Leica Vantage Cine Lenses

I found this by accident at Vantage web page:

leica_vantage-macro60mm.jpg

The following focal lengths are available
19, 21, 24, 28, 35, 60, 90, 135, 180mm, all T2.8
in PL or PV mount.

Maybe this could be the set of Leica Cine Lenses that I heard about it before!!?

If these are normal leica lenses, howcome they are T2.8 and not f2.8 - meaning they would be more like T3 - or not?

Brian,

then you should ask Vantage about that.

Just give them a call after this holidays...

this has confused me with a number of re-housed lenses (the new wide nikon re-house promoted on this list being one of the).

http://www.reduser.net/forum/showthread.php?p=398091#post398091

The 3 possibilities seems to me to be:

1/ In rehousing they manage to squeeze a little more out of the lens.

2/ They simply feel its close enough not to bother re-calculating for true T-stops.

3/ The lens was conservatively marked up in the first place. (I think I've seen this on contax ziess lenses).

After grilling Vantage on their anamorphics (and being very impressed with their professionalism and honesty) I'd have to guess that they would not consider marking up a f-stop as a T-stop..

As for Focus Optics I asked in an open forum and got no answer so I reckon number 2..

PS if my memory serves you lose about 4-5% per surface for modern coatings... so on a modern 10 element lenses that is still a fair amount of light

It's also a far more economical means of manufacturing the lenses. Chris showed me a few of the Leica houses with the wireform track inside, very interesting design indeed. Simple in it's engineering but very effective.

Van Diemen use to be quite big. Here's an interesting fact... Cooke S4 lenses didn't use to have a 14mm, Van Diemen designed one from the ground up to match the set, they later sold the design to Cooke because it was that good. This gives an idea of the quality of the rehouses Van Diemen use to do as Mitch has testified too.

I jokingly advised him to make some 65mm Anamorphic lenses for the Epic 645 :)

Hi Michael, the Van Diemen Leica's were T3.0 which would fit, seems odd, I've rarely heard of converted still lenses having the same T stop as the original F stop.

Here's the complete list of corresponding VD lenses:
19mm F2.8 Elmarit T3.0
24mm F2.8 Elmarit T3.0
28mm F2.8 Elmarit T3.0
60mm F2.8 Elmarit T3.0
90mm F2.8 Elmarit T3.0
135mm F2.8 Elmarit T3.0
180mm F2.8 Elmarit T3.0

Still, I'd rather see a combination of the M and R system glass used to make the following set:
15mm T3.0
21mm T1.5
24mm T1.5
35mm T1.5
50mm T1.5
80mm T1,5

Speaking of Vantage lenses -
I'm surprised no one ever mentions their "B" series of lenses. I shot a film in India and used Hawk "B" series anamorphic lenses (rented from the Prasad film lab.) I only ever knew the C and V series of lenses so I contacted Vantage and they informed me that the "B" series were inexpensive versions of the C series made for the indian market. Same glass but the mechanics and materials were lower in quality. I never did see them listed on their web site, and have not heard of them since. But if anyone is in the market for anamorphic glass, I recommend giving Vantage a call/email to see if new "B" sets are still being produced.

Adios
