At wider apertures, 45mm also covers the FF 2.40 area. 

Just finished in first stage.  Prime lens: Canon EF 40mm STM, actual ratio: ~1.5x

Taken samples, 2.25:1 from 3:2 cmos FF camera by 1.5x ratio. 

The black side is actually the back of the lens, so they are mounted at the front.
I thought this was an alternative design for the Iscomorphot 8/1.5, but there will be others here who know more precisely, Tito or Bold perhaps?

Here is from last summer a little test between FM Lens and Rectilux adapters. Kowa 8z inside on both.
 

A beautiful spot shot in anamorphic. Looks like a Kowa?. Anamorphic zoom? Anybody on EOSHD shoot this? Great job!  
 

Wider means less  vignetting for using the same prime lens.  I still own it.  It has similar size as 16F.  But shorter, and have bigger front glass.  So it could be used on wider taking lens.  So I just simply said it is wider.

Simple Formula: 
Original ratio x anamorphic extension rate = New ratio
So 16:9 with 2x=32/9
 

review of SLR Magic's achromats, I thought it could be useful here.

Hi all,
Inspired by Tito and Bold and their anamorphic Lens-cyclopedia, I decided to try and make a list of low power diopters useful for anamorphic video. Using the info in this thread and searching on the web, I compiled a list which may be useful for anyone looking for suitable diopters.
I've attached the list as PDF. Feel free to comment and/or correct. The list may (hopefully) end up as an add-on to the online Lens-cyclopedia.

Hi guys,
Added these to the list. Great finds Ken! Couldn't resist buying that 77mm KMZ diopter on eBay for a steal...was the last one (for now)!
Cheers,
Tim

IMO, that is pricey.
I also bought the SLR's +0.33 &+1.33 set already.  http://www.ebay.com/itm/271994594777
I think they are double element too.

Just got this one http://www.ebay.com/itm/161898434253 , very happy with it. 
It is a new item. Looks like a good deal compare to original price.

I found f-1734 is a good deal, 77mm.  some one said is 0.6 (means from 1734mm).  but the glass is almost flat (heavy, thick ring), compared to my vivitar 1/2, 62mm, very curved.

4M=+0.25, since 2M=+0.5, 1M=+1, 0.5M=+2....

they are doublets. my review about them is coming in two weeks.
I bought THE EXACT same ones you did. It was a great price, right? Too low to let it pass for two doublets.

Well done, man! +0.25 is hard to get!
I have this minolta, it's almost the same as the Tokina +0.4, except it's +0.33

Hey guys. I've been reading this branch of EOSHD for quite a while now. This is how I got sick with anamorphic lens, and to be frank I love my weird new obsession.
So I wanted to say a big THANK YOU to Tito, Rich, Bold, Ken, Bioskop and many many other members who posted tons of useful information that kept me busy for so many evenings. But I also felt like for a past month I've created way to many threads with questions. By nature I am not a patient person, and this flaw causes me to behave as if I am obsessed, which I kinda am, but still I felt like I probably should make one thread dedicated to everything that I wanted to ask or tell to this community.
 
So I've got the idea of using anamorphic lens when my band started thinking about a new music video. We have a bmpcc and couple of low-end Canon DSLRs in our possession, and it felt like we just need a decent lens and we can turn the world over.  Now that we know we were wrong here's our situation.
 
We have one person who does video production part time and rely on their skills with the camera. We are going to shoot in Carpathian Mountains in early-mid January. The story for the video requires us to shoot two people in a sub zero snowy wilderness.
We have currently this gear: BMPCC, Zeiss Distagon 28 2.8, ISCO Animex and Rangefinder all put tightly together with custom made clamps. This setup sits on the TR.EN (no idea if this is going to tell you anything) shoulder rig that has counter-weight and an arm to press against your belly for support and a follow focus. We also have a Neway 7-inch monitor that does only partial de-squeeze (not 2x, but 1.33x) that we bought due to false feature advertisement and can not return. Camera and monitor are supposed to be powered with Sony batteries that we are yet to acquire. 
Now as we are shooting some test videos to prepare to the actual shooting and get used to the setup we have stumbled upon couple of quirks that we did not foresee. 
1. Ratio. While I saw a thread with Taylor Swift's 3,55:1 music video with 250 million views I still feel like people might be thrown away by this super-wide ratio. I actually re-watched Ben Hur after recent post about Super Panavision and Hateful Eight, and even 2,76:1 feels pretty wide. I feel like 2,55:1 would be something that we can go with, but when we try cropping 2x de-squeezed video from BMPCC to 2,55:1 we get awful blurry results. 
2. Ratio issues bring us to a next major decision that we have to make – is the tiny ISCO and 2X squeeze ratio a way to go for us? I was thinking about this so much that I've decided to try using 1.33 or 1.5 adapters first, but since we're on a budget I could not afford buying one. So I decided to go DIY. We're in Ukraine and we have access to plenty of soviet glass that is much, much cheaper then those ebay prices that you all see. I have recently bought 3 LOMO NAP2-2 lenses for $8. They are all bet up, but good for a project purposes.
What I did was removing front and rear elements in their original metal housings and bring them closer to get 1.33 or 1.5 ratios to test. Because of the fact that I am planning to use Rangefinder in any case I had to somehow achieve infinity that was lost after both elements got closer, so I have bought a cheap -4 diopter glass lens for glasses and fitted it between two anamorphic elements. It is standard 60mm diameter lens and fits inside original rear element housing. Basically I have achieved 1.33x ratio and infinity from the glass that was 2x originally, but I have lost 1 stop too, which kinda bugs me.
Here is a link to an unlisted video from 550d and 28 2.8 Canon AF glass. I like the thin blue flares. I like that fact that it covers 550d sensor with 28mm, whereas ISCO only covers BMPCC sensor with 28mm. 
But the glass that I removed from the beat up lenses is scratched and has fungus damage of the coating (you can see the dots of the flares). I am supposed to receive two pristine LOMO NAP2-3M and NAP2-4 that I got for $25 and try to do the same mod to them too. They are bigger but supposedly capture the same field of view. 
If I decide to go with this glass for the video then I will have to machine a housing for the lens itself, clamps to taking lens and to Rangefinder. 
3. No slomo. While I understand that it is foolish to expect any slomo from a cheap camera like BMPCC I still think that having a little higher frame rate would be nice to soften motion, especially in our case since we're gonna shoot a lot of running, falling and fighting. Currently we have an iPhone 6s in our possession and the soviet glass does not vignette at all, but adapting it to kinda mount it to the phone (or mount the phone to the glass actually) but we are very very uncertain about the results we can get from it. Is it worth all the effort to be a b-cam and shoot 120 or 240 fps? We also are really afraid of not being able to match the results later in post production stage, since iPhone is iPhone and BMPCC is, well, BMPCC.
Considering that we already had the BMPCC the rest of the setup (Distagon, Monitor, Rig, ISCO and all the LOMO lens, clamps and Rangefinder and a powering solution for BMPCC) took us to $1200. Adapting those pristine LOMOs (housings and clamps) would be another $100. We also plan to spend around $200 for renting a house in the mountains for around a week and for al lthe transportation. In the end we are facing $1500 for a video, and a thought keeps buggin' me – should I have bought a 1.5x lens right on and saved some money? I guess I'll never know.
Guys what would you do if you were us? We have already shot to music videos, in 2010 and in 2014, so we really think that we can pull it off in terms of organizing the process and making our ideas real, but in terms of getting an image of a nice quality we really need your advice and thoughts.
I really appreciate if you read the whole thing.

because its focus in near distance, you need let it to focus at infinity.  You can try adding a negative diopter in rear or front to do that.  Imo, it should work.

What editing program are you using, because when i've cropped anamorphic footage using FCPX it stays exactly the same sharpness.
What you need to do is make a custom timeline & then stretch the footage by 200% - the timeline will cut the edges off for you & you should still have the option to move the image from side to side to re-frame.
Personally, i'd stick with your Animex & the Pocket. If you need slow-mo, then you could always ramp the fps to the max & still achieve something ok. I've tried the slow-mo feature in FCPX with 24fps footage & its not too bad - but i hate slow-mo, its over-used & most of the time it doesn't add that much (its become a gimmick at best).
Anamorphic obsession/curiosity can take you to interesting places & you can spend way too much cash just experimenting on failed projects. You've already got a good set up, so use it - it really isn't going to get better than the BMPCC, with or without an anamorphic lens.

Sorry Andrew, didn't want to confuse you, i didn't use LA7200 with rangefinder, i just mentioned it as an example, in s35 at 5k it doesn't vignette, as well as Kowa 16h or ISCO ultra star, from 50mm and up; and putting rangefinder on kowa 16H creates strong vignette, without rangefinder kowa, or blue star , or ultra star don't vignette,
 but this is in 16;9, switching to 2x anamorphic mode fixes this vignette, but as i said i don't like that mode and prefer 3,5:1, but well;
shot some test tonight, 'human feces' will be the next test, but i like this glass. a bit too heavy, i would accept hard plastic framing, cuz for anamorphic setup it is a lens+adapter+rangefinder, gets heavy and bulky, i know, i know, real anamorphics are huge and heavy, just thinking out loud;
So, dear Andrew, are any of new SLR Magic anamorphic lenses cover 5 or 6k, because if they do that would be awesome.
thanks!
 

I think so, due to 3x crop, like BMPCC.  Its image field is already smaller than Nikon-1's 2.7x.
 

Moondog lens + pana mode = super wide angle's widescreen photo
 

100% pixel crop, then can see 2 people in middle
