SLR Magic SLRAC-40133 Overview

  • 1Description

The SLR Magic Anamorphot-40 1.33x Anamorphic Adapter enables you to capture footage with a 2.35:1 aspect ratio on your camera with a 16:9 sensor. This results in an image that out of the camera will look distorted, as if your subjects were stretched taller and thinner than normal. This is easily corrected in post with virtually any modern NLE, creating an image suitable for viewing on wide-screen. The SLR Magic Anamorphot-40 1.33x works with lenses that have a front element physically no larger than 40mm in diameter. For full-frame sensors, SLR Magic recommends that the Anamorphot-40 1.33x be used with 40mm or longer focal length lenses; it is compatible with select wider lenses when using S35 and Micro Four Thirds sensors.

The Anamorphot-40 features adjustable focus marked normal and near. The near adjustment allows you to focus on subjects two feet away; setting the adapter to normal allows you to focus on subjects from three feet to infinity. The Anamorphot-40 mounts to lenses with a non-rotating front and a 52mm front filter thread. This adapter is compatible with full-frame and APS-C camera sensors, and with both automatic and manual focus lenses.

    SLR Magic SLRAC-40133 Reviews

    Anamorphot-40 1.33x Anamorphic Adapter (Compact) is rated 4.0 out of 5 by 10.
    Rated 3 out of 5 by from a toy than a tool good things: - super light compared to other vintage ones. - affordable - great build quality. - works good with my Loxia 50mm lens, even using aperture 2.0, you still could focus if you precisely focus the adapter also. - x1.33 mentioned is much useful than x2 on DSLR. bad things: - no light flare. - no noticeable oval bokeh. - not 1.33 at all. when focus@1m, close to 1.22, focus@2m, close to 1.25. infinity maybe 1.33, I didn't try. no regret, this is just a toy not a tool, a toy means you can't bring it to work, you play with it sometimes, then all the other times, it just lies in your drawer.

    Rated 5 out of 5 by from Owning Anamorphic Texture for Price of Rental I couldn't be more excited about this purchase. Already shot with it a number of times and it's paying for itself quickly. I love the anamorphic look but it's obviously a very expensive look to be into. Been using this with my Panasonic GH5 and 25mm 1.7 and loving the results. Elevates the aesthetic of everything I'm working on. Sharp in the right places. Flarey and dirty in the right places too.

    Rated 4 out of 5 by from Anamorphic on the super cheap Shooting on a Sony A7Rii with FF (for full frame and s35 crop) and speedbooster Nikon converters. Have had it for a day and not done any major testing so these are v early impressions. Pros: - Relatively, super cheap! - Works well with my nikon 50mm and 100mm in full frame and s35, and my 24mm in s35, as well as a Sigma 30mm E-mount. - Don't have to worry about focusing the anamorphic and the regular lens. Set it to Near or Normal and then you can even use lens AF. V nice. No need for a rangefinder attachment. If you try to rack from infinity to 2 feet, though, you might have to try and also switch the anamorphot to Near in the process. - I'm a fan of the blue-ish flares that SLR Magic's lenses give off. Some people aren't. - Light enough that I'm not terribly worried about having to add extra lens support to a rig. Can hand-hold this easily. - The rear filter ring used to tighten the anamorphot to the taking lens is a nifty way to mount it. I like it better than previous screw mount options. Cons: - Maybe it's just my copy, but it looks like dead centre of anything i shoot is hard to get nice and sharp. Anything just a bit off to the side of centre, though, is nice and crispy. - Not getting that classic oval bokeh. A tough proposition on a 1.33 adaptor, but still.

    Rated 2 out of 5 by from Useless Ordered this adapter just 2 workdays ago and it was shipped crazy fast to switzerland. Even faster than the swiss post sends letters within Switzerland! Nice! But now the adapter. Unpacked this item, build quality is very good. Everything from glas and metal. The focus ring is smooth and works perfect. Then i screwed it on my Canon 28mm f1.8 (with C100mkII Body) and an adapter ring between (58-52mm). Works also perfect. I shot some scenes in lowlight. Autofocus of the C100 was also ok. Afterwards i reviewed the material in Premiere and i was very disappointed. First the pixel ratio of 1.33 sqeezes the frame too much, so it is NOT a 1.33 ratio, 1.20 seems to be too less. So its more a 1.25. But that is not possible to choose. Second there were no flares at all. Nothing. But to be honest, thats ok for me. I do not want to shoot anamorphic because of the flares, i want to shoot anamorphic because of the oval bokeh and the horizontal squeeze of the background in relation to the foreground. But ... there was no oval bokeh at all. So the adapter is totally senseless because it just makes the view angel a bit wider, but even not in the ratio of 1.33! I hope i can send this thing back to get refund.

    Rated 5 out of 5 by from Amazing! Best Anamorphic on budget! Very recommended Got the lens in 2 shipping days to Israel from US. The footage with the adapter is amazing on my GH5 and SAMYANG lenses. Did a test and short film already on it. you can find it here

    Rated 3 out of 5 by from Not 1.33x Its a good quality anamorphic adapter. I just tested on a 40mm lens, and the exact ratio is: 16:9 sensor == 2.16:1 3:2 sensor == 1.83:1 So its really a 1.22x squeeze.

    Rated 4 out of 5 by from Needs the right taking lens I personally love the blue flares on this one, I've combined it with a Sigma 30mm 1.4 and do need to stop down a bit to get full sharpness, and its also not the ideal taking lens, a pancake Canon 40mm or Panasonic 20mm seems to be a better combo but I've adapted my Sigma with the Vidatlantic anamorphic iris to get the bokeh I want

    Can you use a rangefinder with this?
    Asked by: Mitch H.
    The SLR Magic Anamorphot-40 1.33x Anamorphic Adapter has a 62mm filter thread for attaching optional filters, diopters, or the SLR Magic Rangefinder Cine for improved focus functionality. So yes, you can use the Rangefinder with this.

    Is the bokeh rectangular or oval?
    Asked by: Charles D.
    Depending on what type of footage. The bokeh at normal lighting have very soft, oval type bookeh.At stronger lighting and when its darker. It gives some good citynight footage with the more long lensflare and lots of visual with wide lens. Giving its the unique footage.

    just received mine- how do you adjust to ensure this adapter is tightly and securely screwed onto the taking lens whilst still being oriented correctly (with the rectangle on the front in 'landscape' orientation- as by default when screwed tightly/securely to my taking lens it's at the wrong angle and at the correct angle it's too loose..)? Thank you for any feedback!
    Asked by: Justin
    The rear has a sliding locking ring. Set up a point light source in the frame of your taking lens. Mount the Anamorphot. Move the rear sliding locking ring forward then rotate the Anamorphot until the blue line created by your point source is horizontal. Then let go the ring and the Anamorphot is locked in place.

    Will this work with Black Magic Pock Cinema ...

    Will this work with Black Magic Pock Cinema Camera and Metabones Canon EF Lens to Blackmagic Pocket Cinema Camera T Speed Booster?
    Asked by: Rosay
    This will depend on the lens itself that is used in this scenario as this adapter only works with lenses that have up to a 40mm front diameter. So that we may best assist you finding the proper product for your needs feel free to email us directly at

    Can you mix desqueezed anamorphic footage with regular 16:9 footage in or do you have to stick to one or the other for a project?
    Asked by: Mitch H.
    While you will have to stick with one final format, usually 16:9, there are many cases where film makers have switched between aspect ratios in a film for effect. You can have a 16:9 project that occasionally switches to 2:35:1 footage with a letter box.

    Would adapters like this be compatible with zoom lenses, like the Sigma 18-35?
    Asked by: steven T.
    It has been reported that you can use the Sigma 18-35mm and the SLR Magic Anamorphot on a MFT camera like the GH4/5 but only at 35mm.
    Answered by: Dennis A L.

    The photo of the adapter shows a 62mm filter thread, and yet the specs claim this is 52mm. Which is correct? Thanks.
    Asked by: Dorian
    On the front of the Anamorphot where you will mount filters, it is 62mm. On the rear of the Anamorphot, it has 52mm threads to mount it on the taking lens.

    What would happen if you use this on the tamron ...

    What would happen if you use this on the tamron 28-75 2.8 FE, 67mm filter thread? Vignette till what focal range?
    Asked by: Nathan
    This product will not work with the Tamron 28-75mm. The diameter of the lens itself is too large to work with the Anamorphot-40, along with the other issues of the focal range and filter thread. The Anamorphot-40 is designed to work with smaller, fixed focal length lenses. The SLR Magic Cine II 50mm f/1.1 Lens (Sony E-Mount), B&H # SL5011FE2, is the best option to work with the Anamorphot-40.
