Sorry, but i cant answer that because i have no DIAX lens for now and dont know how they are connected to the DIAX cam.

Me, i would be interested in more informations about this DIAX interchangeable system. If the registering distance is less than 36.8mm, it makes no sense. As far as i can see in pictures from the rear of the lens on selling offers they have a very special mount and at the moment i cant imagine a coupling with VNEX..

The VNEX can mount Braun Paxette type lenses and maybe in the future we produce a special ALTIX - connector.. so they will fit and if there are enough people interested in such a solution.


Cheers
Henry

There are lenses which have a smaller register distance like the Componon 4/28mm and others..

Here is another example, what you can do with accessory-parts of the VNEX.

The german ROBOT Kameras do have some very interesting lenses, like the Xenar 3.8/7.5cm..



What do we need for Mounting this lens with his own helix to a simple M39 adaptor ?

ROBOT cams do have a register distance of 31mm.. the VNEX has a register distance of 36,8mm.. this means the lens will not fit in terms of register distance and additionally the screwmount does have a diameter of 26mm.. !

With the accessories of the VNEX we can do the following:



1. simple M39 adaptor
2. inner connector for lens connector M39
3. a M27 to M39 changer plate

Here i did prepare the Xenar Lens with the M27 to M39 connector, which will fit into any M39 adaptor.

After that, i screwed in the Xenar and did use the inner connector in the middle as a counternut for the Xenar lens after i adjusted the lens to the infinity point. Its a good way to bring the ROBOT Lenses to a M39 adaptor..



So i did use a cheap M39 adaptor and the two parts.. thats all for mounting ROBOT lenses to the Sony NEX cam..

Cheers
Henry

No, not possible at the moment.. only directly from me.. Very Happy

After the first 10 prototypes, i produced further 25 units to find out the acceptance of such a system..

To hold down the invest, only small amounts of the VNEX units are produced. In this stage it doesnt make sense to sell on ebay.
If the interest for such a system would be to high, i first have to manage the "in time" production to deliver.. and thats expensiv to give an order to the factory. I have to invest a lot of money first.

So i decided to produce and sell this small quantity - series..

If there would be a lot of interest, i will manage more units..

To hold the invest as small as possible, we decided to do some work "by hand" (for example darken the tubes by hand instead of anodizing industrial, no expensiv overpackaging etc..)...

Later, if there should be more interest, we will do the things complete industrial.. its a question of selling enough units for making the necessary invests in such "beautifications"..

If you want one, let me know..

Cheers
Henry

The LEITZ Hektor 2.5/85mm from a Prado 150 projector for 35mm slides, adapted to Sony NEX 7 via the VNEX-System.. pictures and detailed way of adaption with VNEX tools and helix..



This is the optical scheme of Hektor lens.



For the VNEX Users.. what do we need for bringing this lens to VNEX?

First 2 x 12mm connection rings.. or 12+9mm ( the infinity point differs a bit, but can balanced with the position, how you center the lens in the connector)



The inner connector for two of the M39 connector rings, shown before..



The inner ring is for conneting rings for getting good register distance.. here combined inner connection ring with the M39 lens connector.
Screw in the inner connector to adjust the lens in height of about 12mm on the end of M39 lens connector... the lens must be centered and locked after that. The centering you will see in last picture, have a short look while reading this further..



After centering and locking the lens, you have to unscrew the inner connection ring to a position, where you can connect a second M39 connection ring and lock with the 3 screws..



Now you are able to connect to a second M39 ... and to connect to VNEX Helix.. Very Happy



Very Happy

Here are some "quickn dirty samles"..







With this shown solution its possible to focus from about 50cm to infinity..

From time to time i will post more possibilities for the MFLenses buyer of the VNEX.. to show how to bring different lenses to the VNEX... very experimentell things..Very Happy

I would be interested, to see your experiments.. Very Happy

Kind regards
Henry

Embarassed You embarrasses me.. thanks for compliments..

Here is an additional possibility with the VNEX i realize today after getting a Leitz Colorplan 2.5/90mm from a Leitz Pradovit slideprojector.

One of the easiest things to bring to the Sony NEX cams..



For this version of the Colorplan, you need an additional "Retro-Ring" from the VNEX System and the VNEX itself. if you dont want to use the retroring, which came with your VNEX complete Set, you can buy one for 11 Euro + shipping.



This Retro - Ring has a filterthreaddiameter of 40.5 mm for some modern enlarger lenses.. and an inner M39 thread normally for for combining the 25mm extension tube from VNEX System.

The inner diameter of the Leitz Colorplan is exactly 40mm...

This gives the possibility, to use the Retro-Ring in that tube, to build an "inner (female) M39 screw - mount" for connecting the lens to the VNEX M39 part of the focus helix, without the need for one of the normal 6,9 or 12mm connectors..

Have a look..



Now we are ready to connect the lens to the VNEX System.. thats all.

from now on you can focus the Colorplan from about 60-70cm to infinity (and behind)..

Me i did take the Retro-Ring, adding a bit of glue to the 40.5mm thread part and nailed the Retroring in the tube.. fits perfect and makes a very strong connection between this two parts..

For all of you, who likes to make images with open aperture lenses, the Colorplan on the VNEX does a great job.

Unfortunately, weather is bad today.. so i did only some quick Shots..



and a crop..





Cheers
Henry

Ok, here are some first samples of the Leitz Colorplan 2.5/90mm.. taken today in our local store..







Its really fun to play around with that lens, i did buy for 10 bucks.. Very Happy

IMHO its better than the Leitz Hektor 2.8/85mm, but heavier and larger in tube lenght.

Cheers
Henry

Great ones Henry!
Unbelievable clarity!
There was a chap, I think he posted on one of your threads, who sustained that an enlarger/projector lens cannot be used for this kind of photos.
Where is he know to see these ones? ( rhetorical question; I know he's no longer here). Twisted Evil

Very nice indeed ! Very Happy

What are people's reactions when they see you take photos with this combination ?

Very Happy Most of people didn't notice that. Maybe they think .. its an old Leica M2 or so because of the tube in front of the camera..
Maybe they think.. "ouch.. poor boy .. because he cant buy a modern cam".. Very Happy

Only if you travel to places, where photographers with big DSLR cams they are wondering, whats going on with my camera and why is there a silver tube in Front of the NEX.. ???

And sometimes they ask directly whats on that expensive SONY NEX 7 cam.

On the last camera fair in Hamburg i did take the NEX/VNEX combination with me to check some enlarger and other lenses on the VNEX.. before buying..

Most of the sellers are Shocked what is possible today.. Very Happy

But its excellent... you come into discussions with the people, you would really not have without the system. And often the sellers are willing to give a special price for their gear.

On the other hand i have to be careful with informations, if professionel sellers are in the house and see this VNEX. The prices for the lens offerings are growing higher and higher fast for these lenses.. Laughing

Its a nice and funny thing to take pictures with this lenses.. and they are cheap compaired to the "normal SLR lenses" we all do know..

Me i have a very fine collection of Leica, Angenieux, Meyer Görlitz, Canon FD high grade lenses.. for SLR.. i know them nearly all after about 200-300 lenses i did have for finding "my personal" taste in lens behavior.

Sometimes for me reading about "old SLR Lenses" is become a "boring thing". To read the fifth millions Thread of Helios 44M-2 or Leica or Nikon Glas.. and after all these brilliant lenses are out of the "used market" and the prices growing higher and higher, my aim with the VNEX was to see things i havent seen before.. not follow the mainstream any longer.

The VNEX is - as a side aspect beside using enlarger lenses - a great thing to reseach some experimental things and sometimes your ideas with a lens you want to try out, can mechanical fit on the system and sometimes not.

But for sure.. the VNEX is the system for bringing back "the child in the man gene".. Shocked who wants to explore the world of uncommon lenses, you cant simply adapt with an chinese adaptor.

To tinker with the old stuff from slide projectors, cinema lenses, enlarger lenses satisfies the gene in most of mens world, for building something by handicraft.. so beside the photographical aspect for the lenses, it fullfills exactly that part in me

Some of the results are really amazing.. and often you can get similar results only with expensive high end lenses.

For example the Canon SH 1.7/30mm from a Canon DEMI EE 17 halfframe cam.. gives me same or better results (swirly bokoh, beautiful catseyes etc..) compaired to my Carl Zeiss Jena Biotar 1.5/75mm..

The Canon lens i did buy for only 8 Euro... everyone knows, that a Biotar is about 500 Euros !!!

160 g against 580 g on Biotar..

The Biotar is a 70mm beast.. the Canon only 26mm in height dimension.. and 2 x sharper overall.

For me, its a fun to play around with the VNEX and find lots of cheap lenses with exzellent results.. ! So the fun i did have years ago, when i started to collect old lenses for little money cames back with the VNEX.. mostly the lenses are cheap, cheap, cheap compaird to SLR lenses.. and there are a lot more arguments.

My about 50 different lenses for VNEX and Sony NEX are stored in 2 little boxes... 30 x 17 x 8 cm..

For my whole collection of SLR lenses, i do need a cupboard of 135 x 70 x 40cm..

Cheers
Henry

Indeed some incredible results with your VNEX, the Leitz Colorplan is really sharp and what a lovely bokeh Shocked ..
Probably a stupid question and because I must admit I did not followed the all thread Embarassed , is it possible to use your VNEX system and all these great lenses on a DSL-R Nikon body (FF) and with infinity focus Confused Question ......

With lenses which have focal lenght > 80mm ... yes, but you lost about 2mm in focus extension because you have to limit that intrusion of the tube because Nikons do have the mechanical aperture Lever inside the mirrorbox.. if you need the complete intrusion oft the Tube to get infinity with your lens (which i dont know at this point) you are not able to get infinity..

With success we do use the to a T2 > Canon EF Adaptor remounted VNEX Helix with focal lenght > 80mm.. 80mm, 105mm and so on.. no problem anyway.

But i havent got a Nikon, so i cant answer all the questions about the use on a Nikon

Cheers

I guess it should not be a problem. Perhaps I can lent my D1 to Henry for a while so that he can try a bit.

Hi!

Have you considered or attempted use of VNEX on m43? I love my e-m5, but would be very interested to try some of the lenses you've used on it. It looks like a great way to experiment!

I know that m43 has 20mm registration distance, while NEX has 18mm, so it may not be possible, or may be limited in some way the VNEX on NEX is not....

Cheers!

µFT bayonett - mount diameter is to small for the intrusion of the VNEX tube.. unfortunatelly. The mount limits the intrusion.. we need at least a diameter of 40.5mm for the tube intrusion.. but µFT is limited to 36.1 mm ...

So its not possible or better let us say.. to tricky.

So that would be a totally different story with complete different mechanical design to bring the Lenses from M39 to a screw thread of lets say about 35mm diameter for a µFT Version which would be able to intrude deep enough for a proper infinity to a good closeup distance in focus work..

In Additon to that, the max. axial feed would be limited to 7 or 8mm... instead of 14.75mm in VNEX version.

In a µFT version it woud lost the depht of intrusion in the adaptors rear area.. the NEX has a wider diameter on adaptor rear.. so it can intrude in the overall deep of the adaptor. This means, the end of VNEX Helix tube intrudes already to a NEX camera. This is not possible on a smaller µFT mount diameter.. the µFT adaptor itself would already be the limiting factor.

Cheers
Henry

Hi Henry!

I appreciate your thorough explanation. I don't like what you're saying, but I understand it. Maybe I need to get a NEX as well; your invention is making it look very interesting. Giving up in-body multi-axis image stabilization would be pretty annoying, though.

Cheers!

Emphasis mine. I agree! I am really excited about the quality shown, so much so I went and bought a Leitz Wetzlar Colorplan 90mm lens before getting to the "VNEX won't work on a m4/3" (I have a Panny G2) part of this thread. Razz

Still, amazing work to those that developed the VNEX system, really awesome.
