SLR Magic SLRA40-1.33X overview

  • 1Description

The SLR Magic Anamorphot-40 1.33x Anamorphic Adapter allows you to expand your creative horizons, enabling you to capture footage with a 2.35:1 aspect ratio on your camera with a 16:9 sensor. This results with an image that out of the camera will look distorted, as if your subjects were stretched tall and thin. This is easily corrected with virtually any modern NLE, creating an image suitable for widescreen viewing.

The Anamorphot-40 features adjustable focus marked normal and near. The near adjustment allows you to focus on subjects as close as 4' away; setting the adapter to normal enables you to focus on subjects from 4' to infinity. It mounts to lenses with a non-rotating front and a front thread diameter of 52mm; it incorporates an 82mm front filter thread. SLR Magic recommends that the Anamorphot-40 1.33x be used with lenses that have a front element that is physically no larger than 40mm in diameter.

A 16:9 sensor records an image with an aspect ratio of approximately 1.78:1, and if you want to convert that to a more cinematic widescreen aspect ratio of 2.35:1, you could crop your image in post. However, this leads to a loss in resolution and image degradation. The Anamorphot-40 1.33x squeezes the image horizontally, which creates the classic tall / thin image that must be de-squeezed in post. The anamorphic process allows you to capture your image using your entire sensor, so there is no loss in resolution when compared with cropping your image.
Testing before use is highly recommended, especially when choosing which lenses may be compatible with the Anamorphot-40. When using a taking lens with a Sony E-Mount, SLR Magic recommends using either the SLR Magic CINE II 35mm T1.4 @2.8 or higher or the SLR Magic CINE 50mm f/1.1 also at 2.8 or higher. When using the Anamorphot-40 on a taking lens for an MFT mount/sensor, SLR Magic recommends either the SLR Magic HyperPrime 25mm T0.95 @2.8 or higher or the HyperPrime 35mm T1.4 @2.8 or higher.

Please note that SLR Magic cautions that for full frame work a 75mm taking lens is required, a 50mm taking lens may only cover when your camera is in APS-C or S35/APS-C sensor mode. When using this adapter on a 25mm , the image will cover a Four Thirds sensor.
The Anamorphot-40 1.33x screws onto your lens's front, providing the classic anamorphic effect. Once screwed onto your lens, rotate the anamorphot-40 so that the white witness mark is at the 12 o'clock position and the anamorphic effect is horizontal. Then rotate the locking ring counter clockwise to tighten it against the front of your lens and lock the rotation so it doesn't move.
The Normal/Near adjustments ring allows you to fine-tune the focus of your lens for shooting subjects as close as 4' from the lens.
It features an 82mm filter thread so you can attach optional filters or diopters. Please note that SLR Magic indicates that use with diopters may cause vignetting.

    SLR Magic SLRA40-1.33X reviews

    Anamorphot-40 1.33x Anamorphic Adapter is rated 3.0 out of 5 by 2.
    Rated 2 out of 5 by from Not worth the money Bought this guy along with the SLR Magic 35mm 1.2. First off, important to point out that they work together ONLY ON APH-C SENSORS (for FF you will need 50mm+). Otherwise there's a major vignette. That aside, focusing with this thing is very hard, optical quality is very poor (had to stop lens 2-3 stops down to get usable sharpness) and there is a lot of ghosting and color fringing. This is a screw-on but there's no "upright" indicator... That's kind of silly since you need the adapter to be exactly upright to work properly. It doesn't work well with my other lenses, even though they fit the specs from what I can tell (Takumar 55 1.8, Takumar 85 2.0 and Nikon 50 1.4 AIS) - I was unable to get satisfactory image quality on any of these lenses under f5.6. This might work better with the SLR Magic 50 and 75mm, I don't know. Anyhow, I do not recommend this at this price. This should go for about half, even less.

    Rated 4 out of 5 by from Best Budget Anamorphic Option Build: I've owned this adapter for a little over a year and I love it. It is built like a tank and works like a charm. It has a super solid feel and is quite heavy, making it feel like a quality piece of gear. The focus ring is buttery smooth and has a long throw, with standard gearing for follow focuses which is greatly appreciated. The glass is high quality and sharp and can be paired with tons of different taking lenses. Image: The image this adapter produces is completely up to the taking lenses that you pair it with. This goes for the sharpness and also for the flaring of the lens. The out of focus parts of the image have a pleasant anamorphic look (slightly oval) but obviously not as much as a 2x anamorphic. Still, pleasing. I pair mine with vintage Nikkor lenses - 35mm f/2.8, 50mm f/1.8 and 100mm f/2.8 - all have a 52mm front thread that works perfect with the adapter. The 35mm gives the best image and I can shoot all the way open at f/2.8 for a beautiful semi-soft focus (still plenty sharp enough) that lessens the digital feel of the image. It only get's sharper as I stop down. The 50mm works great too, but requires I use f/2.8-f/5.6 for the best results. The 100mm I use sparingly, as this adapter is not meant for longer focal lengths - it is extremely soft until I hit about f/5.6-f/8, but it works great for certain shots. Since all of these lenses are old (1970's) they have a lower contrast and a lesser worn-down lens coating, which helps to produce beautiful anamorphic flares. If you use this adapter with newer lenses, your flares will be minimal or non-existent because of modern lens coatings. Pros: The built in focus ring (range finder) allows you to set your taking lens to infinity and 100% of your focusing is done with the anamorphot. This allows for smooth rack focusing, allowing me to use this adapter on professional shoots without worrying about operability. It is relatively compact for what it is and it works extremely well if used correctly. Cons: I'd give this adapter 5 stars if it weren't for the 2 small quirks with the focus ring. The first being, the focus ring is at the very front of the lens, making use with a mattebox difficult. The front element also extends quite a lot when changing focus from far to near, making use with a mattebox even more difficult. So... I don't use a mattebox with this adapter. Oh well. Conclusion: If you don't have thousands of dollars to spend on a true anamorphic lens and you don't want to use some janky rigged projector anamorphic that requires dual focusing with both the adapter and the taking lens, this is the best option on the market. I highly recommend it for anyone looking to break into the world of anamorphic shooting.
