I also have a flickr account set up to view stills, which is the best way to evaluate sharpness etc

I will shortly have a blog up and running, but you are very welcome to discuss these breakthough products here.

I am interested, this website doesn't make any sense to me and I couldn't find pricing though. Could you put up more videos of the lens, how to put it all together? I am a little uncertain how this works as well, does this mount directly to a camera body? or does it mount to a lens? you said single focus so I am assuming it mounts directly to a camera body, but its also called the adapter so I am not sure. What focal lengths are there? Can you show what up close objects look at a f1.4 or as open as possible so we can see what the bokeh looks like. Thats what I am interested in most is the bokeh that can be achieved from these lenses.

I love anything anamorphic so I'd like to know more. thanks
 
Will there be an adapter that can be used for wider lenses? say a 24, 35.. or even something wider like a 16, 18?
 
Yes, I have optical solutions calculated for such lenses, but they will come later and will be LOT$$$ more expensive.

A full CinemaScope 2/24mm is a beast of a lens ;)
 
Recticlips are short ungraded clips illustrating a feature or an operational aspect of the Rectilux 3FF.
Here we have some slow handheld focus pulls to a WWII memorial over 60ft away, using a Sony E1.8/50mm taking lens behind the Rectilux 3FF.

It is instructional to compare the mumps in this clip with the mumps of a Vantage Hawk between 01:27 & 01:30 in the clip below it, which was shot in the confines of a small living space

In this post, I thought I would provide some insight into the technology behind Rectilux.


I have a considerable collection of anamorphics built up over the last ten years or so and the clip below shows just a small part of my collection.


Every scope seems to have its own personality and over two years ago I started a project to investigate what would be the optimum solution for a focusing group for each scope in terms of spot radius, chromatic aberration and so forth.


The project's aim was to make each scope single focus. The work involved disassembling each scope, taking measurements using good engineering practice and modelling each scope in software. Following that, many iterative solves were conducted to minimise the merit or cost function, which is a measure of goodness, taking into account practical ergonomic issues like for example having a workable stroke.


Over 30 species of scopes were analysed this way and the results have been catalogued and burnt onto the DVDROM that you can see at the end of the clip below. The DVDROM details the best optical prescription for each scope.


Rectilux truly is the vintage look digitally remastered.

More news from Rectilux…

It has been a while since I last updated this thread, so there have been a number of updates. Most significantly the Rectilux 3FF series has been introduced, featuring the lightweight 3FF-W model and the ultra-light Rectilux 3FF-S. Information on these groundbreaking single focus optical attachments can be found on this webpage:

http://www.transferconvert.co.uk/cinemania/rectilux-3ff.html

where you can find the brochure for download and also a white paper providing insight on how these units work. The ordering process for 3FF series is well underway and the introductory offer for batch1 3FF-W will close on February 10.

Rectilux 3FF series support a wide range of projection anamorphics and more will be added. Rectilux also features a quick change system, offering less than a one minute swap out in the field for aesthetic reasons such as looks and flares. At the moment over 12 anamorphic lenses are supported, which means for example, a shooter can catch the sunrise with a Bolex, then during the day use a Schneider Cinelux, then golden hour and indoor shooting with a Kowa which has the widest FOV, then sunset and night time in bars and cafes with the HyperGonar 16.

Rectilux 3FF series is also available in all black.

More News from Rectilux...


I have been asked many times about the focusing details. Version 2 of Rectilux 3FF-W is as follows:


3FF-W has a Focus throw of 170 degrees (less than 1/2 a turn) from 0.6m to infinity, the stroke is 21mm from 0.6m to infinity


One third of the above is devoted to the close range 0.6m to 1m, which means that the Focus throw is 117 degrees (less than 1/3 turn) from 1m to infinity, the stroke is 14mm from 1m to infinity.


Also, for information I have made available for download, the Schneider Kreuznach brochure on the ES Cinelux Anamorphic 2X MC that I have kept in my archives from the period here:


http://www.transferconvert.co.uk/cinemania/ESanamorpH.pdf


The brochure has a paragraph as follows: "The performance of any lens is determined by the type and quality of the glass used, the elegance of the lens design, and the quality control and skill used in the manufacturing process. The number of elements in a lens design doesn't determine lens quality or performance, it's how well these elements are made and combined, that does."


Those who have been following the development of Rectilux, the original single focus attachment for anamorphic projection lenses, will know that this statement is in perfect harmony with Rectilux design philosophy and manufacturing processes.


Consequently, I truly believe that the only available single focus attachment which is capable of unleashing the performance of this remarkable optic is the one you see above.


The introductory offer for batch 1 Rectilux 3FF-W will close on February 10 2015. If you want a Rectilux 3FF-W quickly, don't forget the bus will leave on this date.
 
FLOATING ZONE FOCUS EXPLAINED


Nikon calls this Close Range Correction and Canon calls it Floating Element, so for the sake of accuracy Rectilux calls it Floating Zone Focus.




Back in the day, when lenses were focused by moving the whole cell forward and back from the film plane, it was noticed that when close focused, the image quality suffered. For example, it is usually found that say a vintage 135mm lens would typically be limited to 1.5m close focus for this reason.




Nikon found that by shuffling the distance between lens elements, using a mechanical cam system that they could tighten up the dispersion of the imaging rays to give much improved close focusing capability. Rectilux does the same thing but manually as detailed below.





As you know Rectilux 3FF-W will focus from 0.6m to infinity when the anamorphic and taking lenses are simultaneously set to infinity.


Call this configuration ‘INF-INF’




Now say you are on set and the shot list says you don’t need to focus on anything beyond 5m. Just set your anamorphic and taking lenses simultaneously to 5m. Call this configuration ‘5-5’. Thus 5m is the new infinity and means that you can shoot from 5m down to much closer than 0.6m (I will leave you to do the calculation) and the close shots will be much crisper than the configuration ‘INF-INF’. Of course the whole stroke is available to you, so much precise focus is easily obtained.


Now say you have a romantic candlelit dinner scene. You want lots of bokeh and also want to use it to blot out background distractions. Storyboard calls for reverse head shots and you tell your AC to configure Rectilux to ‘2-2’, meaning set the anamorphic and taking lenses simultaneously to 2m, so now 2m is the new infinity and gives you very close focus capability, so that when the guy proposes and puts the engagement ring on his GFs finger you are there to scoop it up, filling the frame with this shot.


I suspect now you will come to realise the additional advantage of the quick change system, enabling you or your AC, to quickly remove the scope and set it to the desired ‘X-X’ configuration and put it back ready to shoot.
