SIRUI 50mm f/1.8 1.33x Lens Announced – Affordable APS-C Anamorphic Lens

September 16th, 2019

SIRUI announced their new 50mm f/1.8 1.33x anamorphic lens during this year’s IBC show in Amsterdam. The lens produces image circle covering APS-C sensors and will come in versions with Sony E-mount, FUJIFILM X-mount, and Micro four thirds mount. Compared to other anamorphic lenses, it will be very affordable.

Anamorphic lenses can produce unique images with special characteristics (lens flares, oval bokeh, etc) and that’s why they are very popular for certain genres. For years, there have only been very expensive anamorphic lenses on the market and the only affordable alternative was to use an anamorphic adapter (like this one from SLR magic). This is changing and there are more and more affordable anamorphic lenses available. My colleague Gunther recently reviewed the VAZEN anamorphic 1.8x 40mm T2 lens fo M4/3 cameras. SIRUI is now introducing their own anamorphic lens.

SIRUI is a chinese camera accessories manufacturer. Previously, they have been mostly producing tripods and various mobile phone accessories, like lens adapters, stabilizers, etc. During this year’s IBC they introduced what seems to be their first lens ever. We talked about the new SIRUI 50mm f/1.8 1.33x anamorphic lens with SIRUI’s european marketing director Sonny Liu.

SIRUI 50mm f/1.8 Anamorphic 1.33x Lens

SIRUI anamorphic lens produces an image circle large enough to cover APS-C sensors. It will come in three versions for different camera mounts – Sony E-mount, FUJIFILM X-mount, and Micro four thirds (M4/3) mount. It only offers manual focus.

Because it is anamorphic, the FOV is wider, than what any traditional 50mm lens would offer. It enlarges the FOV by up to 33%, so the equivalent FOV would be roughly 37.5mm. With 16:9 sensor setting, the resulting image will have an aspect ratio of 2.4:1.

This SIRUI lens has typical characteristics of a real anamorphic lens, like backlighting effects and lens flares, oval bokeh, etc. Compared to other anamorphic lenses on the market, it will be very affordable.

SIRUI Anamorphic Lens – Key Specs

  • Lens structure: 11 elements in 8 groups
  • Aperture blades: 10
  • Aperture: f/1.8-f/16
  • Sensor coverage: up to APS-C
  • Shooting distance: 0.85m to infinity
  • Focus method: manual focus only
  • Maximum magnification: 1:15.38(V), 1:20.17(H)
  • Filter spec: M67 x 0.75
  • Rotation angle of the focus ring: 143.6°
  • Max. diameter: 68.2mm (2.69″)
  • Diameter of the focus ring: 61.7mm (2.43″)
  • Total length (without lens caps): approx. 106.6mm (4.2″)
  • Weight: approx. 553-562g (1.22-1.24 lbs)
  • Lens mount: Sony E-mount, FUJIFILM X-mount, M4/3 mount

Price and Availability

SIRUI 50mm f/1.8 anamorphic lens should be available in the early 2020. Price will be roughly around €700 (which I expect to translate to around $700-800). In the world of anamorphic lenses, this really means affordable. I hope the performance will not be compromised too much due to the price.

What do you think about the affordable SIRUI anamorphic lens? Do you have experience shooting with anamorphic lenses? Let us know in the comments underneath the article.

Considering the rise in bmpcc 6k sales, I would love to see an EF mount version of these lenses. Preferably full frame.

This seems like a perfect lens for location scouts or very run and gun 2nd unit. I would love to add this to my kit for prep. The price is quite right. The issue has always been when you’re prepping for an anamorphic shoot you can never bring the lenses with you. They’re bulky, expensive, and hard to mount on a still camera. I usually look up the spherical equivalent for my set and try my best to keep to those numbers. This opens up new opportunities. Would be excited to test it against PL and PV glass.

“Because it is anamorphic, the FOV is wider, than what any traditional 50mm lens would offer. It enlarges the FOV by up to 33%, so the equivalent FOV would be roughly 37.5mm”… So on APS-C it is a 56 mm full frame equivalent right ?

This isn’t a big deal, but isn’t Sony FE for full frame lenses (even though it’s identical to Sony E)

Cool… But why wouldn’t you put gears on the lens!?!

To our knowledge, this part might be re designed and gears will be included. Will try and verify.

It makes no sense to use this with a 4:3 sensor, why even write that?

Was wondering the exact same thing. To get 16:9 with anamorphic attributes i guess? The 1.33x anamorphics though never have much of the Ana character tbh – check Hawk ones and even they dont

Hi Peter, funny we have similar family names.
Where do they speak about a 4:3 sensor? They mention M4/3 which is a sensor size, and yes they usually have a 4:3 aspect ratio. However, on the one hand they are capable of recording 16:9, so you would then get a cinemascope image, or as someone answered, if recording on the full 4:3 sensor, you have higher resolution, an anamorphic effect and a standard 16:9 final image size. So in my opinion it makes plenty of sense. As it is, I record 16:9 on my M4/3 camera, I don’t even think I can do 4:3 video (I have to look into that), so I am very interested in these lenses for my M4/3 camera.
Cheers

Guys. Thank you for taking the time to watch the video and comment. The lens is not 100% done yet. It is at a pre-production stage. According to SIRUI, they are committed to do their best in order to bring to the market a high quality affordable anamorphic lens and we are truly looking forward to see how the final version will preform. Thank you!

Bring it with a PL mount and reduced flares and you have a customer.

I noticed the flares not aligned properly in the samples Johnnie has shown. Hope they fix this as this looks promising.

You are absolutely correct! I hope they fix that too. I do want that lens.

Horizontal flares are a little too strong (distracting) for my taste but a good start nonetheless. 2x anamorphic would be a nice option too!

That is what I thought too. Why overlook the PL mount? I guess it is made for the indie market and indies tend to not use PL mounts.
I would like t ok use this lens on my Super 35mm sensor.

ursa mini pro can use a pl mount, and the old canon c300 had a pl version too

Interesting that they are making these (at the moment) without focus gears. Looks more like a photography lens than a filming lens. But I’m here for affordable anamorphic. I never understood why anamorphic hasn’t gotten down in price yet. We’ve had it for decades.
