Shenyang China, Dec 19, 2016 – Zhongyi Optics (ZY Optics) has released a new compact Super Macro Lens for full frame cameras, the Zhongyi Mitakon 20mm f/2 4.5x Super Macro Lens and it features a high reproduction ratio up to 4.5:1.

Zhongyi Mitakon 20mm f/2 4.5X Super Macro Lens is very compact in its class which allows photographers to capture extremely fine details or patterns with ease. The lens is capable of creating unbelievable macro images ranging from 4x to 4.5x magnification. Users no longer need to DIY or use any extension tubes to reach high magnification shooting. It incorporates a 6pcs of elements in 4 groups structure which delivers impressive resolution from corners to corners. Weighing merely 0.5 lbs (230g) and 6cm long, it is a perfect companion for wildlife and outdoor shooting. The wide angle of view and close focusing distance allows you to compose creative images with more information included into the frame. Greater magnification (up to 13:1) can also be achieved by stacking extension tubes or bellows. The high magnification is also extremely useful for scientific purposes.

The enclosure of the lens is made of metal to strengthen its durability. Canon EF, Nikon F, Sony FE, Sony Alpha, Pentax K, Sony E, Micro Four Thirds, Fuji X mounts are available.

Pricing & Availability

Zhongyi Mitakon 20mm f/2 4.5X Super Macro Lens is now available to ship and purchase at ZY Optics authorized resellers and at our official website (http://www.zyoptics.net/). The Recommended Retail price is USD 199.

    Really interesting lens and economically priced

    • Dmitry Anisimov

      There are actually a lot of such lenses in microscopy mounts (e.g. RMS mount). It’s a lot cheaper to buy RMS lens + adaptor.

  • Is it really possible for 20mm lens with 20cm minimum working distance to have 4:1 reproduction ratio? Nikon 40mm is 16cm for 1:1 ratio.
    I thought the wider the lens is, and the higher ratio it has, the closer it must be.

    • Vitaliy Gyrya

      That’s what I was thinking as well.
      I suppose (if the numbers are correct) the only way this is possible is if Mitakon is longer. Since the 16cm and 20cm are the distances to the sensor vs front element.

      • I forgot about that. Yes, if this lens can extend so long so its front element is some milimeters away from subject, yes 4:1 is possible.

        • Zos Xavius

          Yeah, working distance is always indicated by the distance to the sensor and not the front element. They do this because flange distances change between mounts so the number stays consistent regardless of mount if that makes sense.

    • Dmitry Anisimov

      20 cm refers to distance between image and object, not object and front lens!
      >closer it must be.
      not necessarily. in can be retrofocus.

  • Vitaliy Gyrya

    This is a front element of a microscope with just a few millimeters of working focus distance 🙂
    See the spread of reproduction ratios: 4:1-4.5:1

    • Dmitry Anisimov

      if it’s conventional double Gauss at 20mm, then the working distance can be expected to be ~ 13 mm.

  • WillWeaverRVA

    Yeah, this is basically a microscope lens attached to a SLR lens mount adapter, but the results actually look interesting, and that’s a really good price for something like this.

  • Duncan Dimanche

    damn !!!! That’s an amazing little lens !

  • Wow, I think I’d try one for only $200.

  • Ivan Kutsarov

    Very interesting. Back in the days in 1980 Olympus OM System had similar lens Zuiko Auto-Macro 20mm f/2. It even looks very similar.


  • Paul H.

    The ratio here is quite similar to what I get with a reversed 24mm lens. This lens would be preferable to my setup since you could actually see what is in your viewfinder much better, but the reversed 24mm (an old Pentax) is cheap on ebay and the adapters are cheap as well…

  • TwoStrayCats

    I prefer to be a safe distance from some of my subject matter!

    • Dmitry Anisimov

      yes, but for such magnification increase of working distance would make lens larger and more expensive.

      • animalsbybarry

        Canon makes a 65mm f2.8 1x-5x supermacro
        A bit more expensive at over $1000

        • Dmitry Anisimov

          But I guess it works with focus stacking in Magic Lantern and you can change magnification without changing lenses xD

          • Joel Germain

            you dont need magic lantern to make it work and the lens is very nice. But the ratio is really for scientific use. We use it for focus stacking at my work, but in office use it straight on.

          • Dmitry Anisimov

            Manual focus stacking is inconvenienient

          • peevee

            MP-E 65mm is manual focus, so Magic Lantern is not going to help.

            BTW, you can buy pretty cheap Olympus TG-4 underwater P&S and have all that macro with focus stacking built in, with similar magnification due to small and dense sensor.

          • Dmitry Anisimov

            oh I thought MP-E is an AF lens xD anyways I don’t have money for it. I use 4x at APS-C, so small sensor camera has to do 1:1 to counter that. What is the magnification for TG-4? And working distance? Many compacts shoot macro only at wideangle

          • peevee

            It’s working all the way to 1cm working distance between 30 and 100mm-eq (100 being the end of its range). And remember, its lens does not extend (or extends internally in vertical direction, being a sealed camera).

            It is really amazing as a macro thing, and one of the best underwater compacts too. Not perfect, more manual control would not hurt, but it makes hard things so easy.

  • silmasan

    This probably could be used to help you clean your sensors.

  • drpeters

    Three aperture blades? Weird.

    • Zos Xavius

      Not really. There are a lot of 3 bladed designs out there.

      • drpeters

        There are? Which ones? Do they tend to be macro/specialty lenses like this one? I’ve seen some crazy numbers of aperture blades and have a few in my collection, but I haven’t found one with just 3 yet.

        • Zos Xavius

          Lots of older lenses. Some old Zeiss lenses only have three blades and quite a few of their older cinema lenses. Also point and shoot comeras commonly used three blades.

  • jojo

    While this is said to be “a perfect companion for wildlife and outdoor shooting”, I rather think the limited magnification range of 4x to 4.5x will rather limit its uses. It certainly has a niche, but I think many users will be disappointed by its lack of flexibility. Look out for used versions in the near future? Canon’s 1x to 5x macro 65mm will be a lot more flexible in a similar area, but for $199 perhaps this is worth it just for the learning experience and fresh outlook?

  • Dmitry Anisimov

    Sorry I can’t give advice because I already had lenses around and never really looked for them.

  • Hans Arvid Johansen

    My humble experience is with a reversed lens you will get problems taking sharp pictures with magnification over eg. 3x (more or less).
    Main problem for me was my pulse (tried to take pictures in between heartbeats…), breathing etc.. Stacking images was totally impossible, but I guess I’m not experienced enough 🙂

  • peevee

    20mm at 4.5x. How are you supposed to light the subjects, only translucent samples on glass with backlight, like with microscopes?

    • Grant

      I received this lens about over a week ago and love the magnification. I’m new to photography and loved macro photography and a friend shared this with me. I noticed it’s hard to get things illuminated so I ordered this: https://www.aliexpress.com/snapshot/0.html?orderId=81331832155704

      I noticed the lens cap for this 20mm is the same that comes with these lenses that go on mobile phones made in china. So I figured I’d look for a ring flash that would work for those types of mobile phone lenses and sure enough I found that link. I’ll modify it somehow so that it sits around the lens and then power it with a portable usb power bank. I’ve done some macro and this is getting close to microscopic which is fun
