Preliminary Specification**:
  • super sharp anamorphot utilising optics that won Schneider Kreuznach Academy Awards for technical achievement
  • 4 K aquisition friendly
  • focal range from 0.75 metre to infinity, without dioptres
  • large 50mm rear optic port
  • 2X aesthetic, stunning blue flares and 2X oval bokeh
  • support for Flex-eDrive* focussing accessory
  • supports lenses from 40mm (APS-C) for 2.35:1 format
  • supports lenses from 30mm (APS-C) for 2.35:1 format via Canon RAW 4:3 crop modes 
  • lens support for 15mm rod/rail systems included, for quick lens change and assured vertical alignment
  • suitable for manual, auto focus and rotating-front-element lenses
  • push on lens shade included, easily removeable
  • 77mm filter thread included

The first batch have been booked with the Precision Engineering company for next month. They have quoted 4-5 weeks for delivery. Then after delivery, they have to be assembled and aligned at my facility. Then, I will shoot some footage and the first people to place orders will be served first.

 

I will not accept any purchase orders until the first batch are in my hands, tested and I can substantiate my claims.

 

When I have the footage the whole world will know about it :)

I have an update bulletin on Rectilux No 5.
 
The last weeks have been spent dismantling the first batch of lenses to harvest the very special Schneider glass which is a process not to be undertaken lightly.
 
I have prepared the parts for modification/fabrication and yesterday delivered the parts with the CAD files to the precision engineering facility.
 
The precision engineers have given a 4-5 week estimate for completion.of the first batch.
 
After this period the lenses will be assembled, precision aligned and tested. Each one will undergo a testing procedure in line with my policy on quality control. 
 
Pricing will be available after the first batch is tested, when I will have the full costs including BOM and labour actuals on the spreadsheet.
 
The testing procedure will be quite thorough (alas, no drop tests!!) and I request that should you have any specific test you would like to see happen, just contact me before the end of August.
 
The end of August should be an exciting time, if all goes well and to plan.
 
Then there is Rectilux No8............(more later)

Hi Everyone,
 
I have an update bulletin on Rectilux No 5.
The last weeks have been spent performing mechanical tests on the first batch which came back from the precision 
engineers and some minor adjustments were found to be required in line with my policy on quality control. 
 
The exciting news I have to report is that I have revised the specification above upwards so that the minimum focus is now 0.75m. Thus the focus range is 0.75m to INF without any need for dioptres. I repeat NO DIOPTRES required.
 
From early optical testing, I found that a minimum focus of 0.75m was achievable with a 1.8/50mm back lens at F1.8. 
Furthermore this minimum focus is so sharp that a page of ariel text pt size10 is showing focus peaking at 10x LCD 
magnification even with the sharpness and contrast on the camera turned to the minimum, which means that 4k video 
resolution is perfectly achievable throughout the focal and aperture range.
 
When the mechanical changes have been implemented by the precision engineers, I will embark on more formal testing 
and provide samples.

      Hi everyone!
      I wanted to showcase my passion project "The Night Knows No Shore" here on EOSHD. I've been a long time reader of Andrew's blog and it was his footage that inspired me to get an Iscorama a long time ago. 
      After doing tests with it for a while I came up with this idea for a movie. And you can now see the result on youtube: 
       
       
      It's a project made by one single actor and one single crew member (me) with one single focal length (a Canon FD 85mm 1.8) and one single focus anamorphic lens ( Iscorama pre-36). Don't expect much action. It's a slow film with lots of monologues and no real plot. It's about one young man's thoughts on society, religion, art, philosophy, life in general. Have a look. If you don't like all the "pretentious" talking, maybe you like the footage. Let me know what you think. If you have any questions, just ask. Enjoy!

      I'm selling a copy of the smallest Anamorphic lens in the world, the Baby Hypergonar 1.75x. It's been said there were only about 50 of these ever made. Designed by the OG, Henri Chretien, and made in 1957.
      It is in great condition. Comes with a little black carry case. Really lovely copy, no scatches, fungus, haze. Body is in great shape. There are a few small coating blemishes on the front, but they are so hard to see I couldn't even capture them in the pictures, and they don't show up in performance. 
      Can be used by just focusing your taking lens or in combination with a single focus variable diopter. Neutral unique flares and beautiful rendering.
      - PRICE: $1500 USD
      - LENS NAME: Baby Hypergonar
      - CONDITION: Near Mint Optics, Mint Body
      - PAYMENT METHOD: PayPal
      - LOCATION: Los Angeles, CA, USA
      - FEES & SHIPPING: PayPal fees and shipping paid by buyer.
       
      Please PM me if interested
      .
