NONS SL660 - Interchangeable Lens Instant Camera
BIKMAN TECHInstant photography is making a powerful comeback, but most instant cameras leave serious photographers wanting more. Limited controls, fixed lenses, and tiny prints just don’t satisfy the creative itch. Enter the NONS SL660 – a groundbreaking analogue SLR instant camera that shatters every expectation. At BIKMAN TECH, we’ve taken a deep dive into this unique device to bring you everything you need to know. In this comprehensive guide, we’ll explore its design, performance, compatibility with vintage lenses, and real-world usability. Whether you’re a seasoned film shooter or an adventurous beginner, read on to discover if the NONS SL660 belongs in your camera bag.
1. Product Overview – What Makes the NONS SL660 Unique?
The NONS SL660 is not your typical point-and-shoot instant camera. Born from a successful Kickstarter campaign and crafted by Hong Kong-based NONS, it is the world’s first interchangeable-lens SLR instant camera that uses Fujifilm Instax Square film. Its predecessor, the NONS SL42, proved there was a hungry market for manual control in instant photography. The SL660 takes that concept further with a full-metal body, a passive Canon EF lens mount, and a bright pentaprism viewfinder. This camera is built for photographers who demand shallow depth of field, precise focusing, and the ability to use classic glass from brands like Nikon, Pentax, and Zeiss. It transforms instant film from a casual novelty into a serious creative tool.
2. Key Features That Set It Apart
The NONS SL660 packs a suite of features you won’t find on any other instant camera. Let’s break down what makes it special:
- Interchangeable Lens System (Canon EF Mount): The camera uses a passive EF mount, opening the door to thousands of vintage and modern manual-focus lenses. With simple adapters, you can mount M42, Nikon F, Pentax K, and many other lenses.
- Full Manual Control: You get 10 mechanical shutter speeds from 1/250s down to 1 second, plus a Bulb mode for exposures up to 999 seconds. Aperture is controlled directly on the lens.
- Optical SLR Viewfinder: The roof pentaprism viewfinder provides bright, accurate through-the-lens framing. This is a game-changer for composing shots with precise focus and depth of field.
- Built-in Optical Field Extender: An internal three-element multi-coated optical system projects a full-frame lens’s image circle perfectly onto the 62×62 mm Instax Square film area.
- Multiple Exposure Mode: Because film ejection is manual, you can expose the same sheet of film multiple times without any risk of damaging the remaining frames.
- Hot Shoe for External Flash: A standard hot shoe syncs at up to 1/250s, giving you full creative lighting control.
- USB-C Rechargeable Battery: The built-in 3200mAh battery charges via USB-C and lasts for approximately 100 shots per charge.
3. Design and Build Quality – A Tank Made for Creatives
The moment you hold the NONS SL660, you know it’s built differently. The body is machined from CNC-anodized aluminum alloy, which gives it a dense, premium feel. The shutter speed dial is stainless steel with a polished finish, and the included wooden hand grip adds a touch of warmth to the industrial design. Measuring 135 x 131 x 92 mm (5.3 x 5.2 x 3.6 inches) and weighing 850 grams (30 ounces) body-only, this is not a lightweight camera. We found that the heft inspires confidence – it feels like it could survive a drop. However, the ergonomics are a bit blocky, and extended shooting sessions can tire your wrist. The wooden grip helps, but smaller hands may struggle. Overall, the build quality is exceptional for a niche instant camera.
4. Performance – Where Skill Meets Film
The NONS SL660 demands that you know the exposure triangle. There is no autofocus, no automatic exposure, and the built-in light meter is non-TTL (it sits above the lens). In practice, we recommend using a handheld light meter or a smartphone app for best results. The camera shines in controlled lighting or overcast conditions. The maximum shutter speed of 1/250 second is a notable limitation with ISO 800 Instax film – you will often need a neutral density (ND) filter to avoid overexposure in bright sunlight. Focus is entirely manual, so expect to take your time. The reward? Uniquely beautiful instant prints with creamy bokeh that no other instant camera can replicate. Image quality is ultimately capped by the film’s dynamic range and resolution, but that’s part of the analogue charm.

6. What’s in the Box?
When you unbox the NONS SL660, you’ll find the essentials to get started:
- NONS SL660 camera body
- Detachable wooden hand grip
- USB Type-A to Type-C charging cable
- User manual (basic operation guide)
Note that the camera is sold as a body only – you will need to purchase a lens separately, as well as a pack of Instax Square film.
7. Compatible Lenses and Accessories
The NONS SL660 truly shines through its lens compatibility. While NONS manufactures two native EF-mount lenses (a 35mm f/2.8 and a 50mm f/1.8), the real magic happens when you adapt vintage glass. With inexpensive adapters, you can mount lenses from:
- M42 (Pentax, Zeiss, Praktica, etc.)
- Nikon F (non-G lenses with aperture rings)
- Pentax K (PK mount)
- Contax/Yashica (CY)
- Olympus OM
- And many more
We strongly recommend using lenses with manual aperture rings, as the camera cannot communicate electronically. An essential accessory is a variable ND filter – it will save you from overexposed shots in bright daylight. External flashes with manual power control also work beautifully via the hot shoe.
8. Ease of Use – A Deliberate, Rewarding Workflow
Let’s be honest: the NONS SL660 is not for casual snapshooters. The workflow is methodical. First, load an Instax Square cartridge and eject the dark slide. Then, cock the shutter using the lever on the side. Set your desired shutter speed on the top dial. Look through the viewfinder, manually focus your lens, and compose the shot. Press the shutter button (located on the right side of the lens). Finally, press the manual film eject button on the back to process the print. We appreciate that the camera forces you to slow down – each shot becomes intentional. The light meter is helpful but not TTL, so don’t rely on it blindly. After a few rolls, the process becomes second nature.
9. Battery Life and Real-World Usability
The built-in 3200mAh battery delivers about 100 shots per charge, which we found accurate during testing. The USB-C charging is a modern touch – you can even top it up with a power bank in the field. An auto-off feature prevents accidental drain. In real-world use, the NONS SL660 excels in studio settings, street photography on overcast days, and artistic portraiture. It struggles in fast-paced situations due to the lack of autofocus and the manual film ejection step. However, for photographers who love the analogue process, this is not a flaw – it’s a feature. The resulting prints have a distinctive, nostalgic look that digital filters cannot replicate.
10. Sustainability and Longevity
The NONS SL660 offers some sustainability advantages over digital cameras. Its machined aluminum body is durable and recyclable, and the analogue nature means no planned obsolescence driven by software updates. The camera encourages thoughtful shooting, which reduces waste compared to digital’s “spray and pray” approach. However, the biggest environmental downside is the single-use plastic cartridges of Instax Square film. For repair, NONS does not widely publish spare parts availability, which could be a concern for long-term repairability. Still, compared to most consumer electronics, this camera is built to last for decades if treated well.

12. What Other Photographers Are Saying
Consumer feedback for the NONS SL660 is passionate but mixed. Enthusiasts on forums like Reddit and dedicated instant photography groups praise its unique capabilities and build quality. Many call it a “dream come true” for analog lovers who want bokeh on instant film. However, we also found a number of critical reports regarding quality control. Some users experienced battery failures or mechanical issues after a few months of light use. A few mentioned unresponsive customer service. The consensus is that when the camera works, it’s phenomenal. But there is a perceived risk in terms of long-term reliability. We recommend buying from a retailer with a solid return policy and testing the unit thoroughly upon arrival.
13. Is the NONS SL660 Right for You?
The NONS SL660 is a niche tool, not a universal camera. It is best suited for experienced photographers who already own vintage lenses and understand manual exposure. If you love the tactile process of film photography and want to create instant prints with shallow depth of field, this camera has no competition. On the other hand, if you just want simple, fun instant snapshots, a Fujifilm Instax Square SQ6 or SQ1 will be cheaper and easier. The SL660 demands patience, practice, and a tolerance for occasional failure. But for those who click with it, the rewards are deeply satisfying.
14. Final Thoughts – BIKMAN TECH’s Take
The NONS SL660 represents a bold vision for instant photography. It successfully bridges the gap between traditional SLR cameras and the instant film format. We applaud NONS for creating a product that prioritizes creative control over convenience. Yes, it has limitations – the shutter speed ceiling, the weight, and the inconsistent quality reports. But for the right photographer, those are small prices to pay for the ability to shoot instant film with a classic 50mm f/1.4 lens. At BIKMAN TECH, we believe innovation comes in many forms. The SL660 is not for everyone, but it is perfect for the passionate few who demand more from their instant camera. Ready to explore analogue creativity?
