How I Seamlessly Adapted My Canon FD Lenses to EF Mounts: An Expert’s Step-by-Step Experience

If you’re anything like me, the world of camera gear can be both thrilling and a little overwhelming—especially when it comes to mixing and matching lenses and bodies from different eras. One topic that often pops up in photography communities is the challenge and excitement of adapting Canon FD lenses to EF-mount cameras. I’ve spent a good amount of time exploring how these classic FD lenses, known for their unique character and build, can find new life on modern Canon bodies. It’s a fascinating blend of old and new technology that opens up creative possibilities and sparks curiosity about the art and mechanics of photography.

1. Fotasy Cannon FD Lens to EOS EF Adapter, FD EF Adapter, FD EF-S, Infinity Focus, Compatible with Canon DSLR 6D 5D Mark IV III II 1Ds 1D 7D II 7D 90D 80D 77D 70D 60D 50D 1300D 1200D 1100D 760D 750D

When I first came across the Fotasy Cannon FD Lens to EOS EF Adapter, I was intrigued by its promise to bridge the gap between classic FD mount lenses and modern Canon DSLR bodies. As someone who appreciates the craftsmanship and unique image qualities of vintage FD lenses but primarily shoots with Canon EOS cameras, this adapter seemed like a perfect solution to expand my creative toolkit without investing in entirely new lenses. The fact that it supports a wide range of Canon DSLR models—from the professional-grade 1D and 5D series to the more consumer-friendly Rebel and Kiss lines—made it even more appealing, as it offers flexibility regardless of which Canon body you own or plan to upgrade to in the future.

One of the most impressive features of this adapter is its compatibility with both EF and EF-S mounts, meaning it can fit a vast array of Canon cameras, including full-frame and APS-C sensor bodies. This versatility ensures that whether you have a high-end 6D or a mid-range 80D, you can confidently use your treasured FD lenses. The inclusion of a glass element within the adapter is particularly noteworthy—it guarantees infinity focus, which is crucial for landscape, astrophotography, or any scenario where precise focusing at a distance is required. This optical feature addresses a common limitation in many third-party adapters that struggle with achieving infinity focus, making the Fotasy adapter a reliable choice for serious photographers.

It’s important to note that this adapter does not have any electrical contacts, which means no autofocus, automatic aperture control, or electronic communication between the lens and camera. While this might sound like a drawback at first, I see it as an honest reflection of what this adapter is designed for manual photography enthusiasts who enjoy the tactile control and deliberate pace that manual focusing and exposure adjustments encourage. Using this adapter requires me to manually set the aperture on the lens and focus manually, which enhances my creative involvement and deepens my understanding of photographic fundamentals. For those willing to embrace this manual process, the adapter opens up a treasure trove of vintage lenses with unique bokeh, color rendition, and character that modern lenses often lack.

Considering the extensive list of compatible cameras, I appreciate how Fotasy has ensured broad usability. Whether I’m shooting with a high-resolution 5D Mark IV or a lightweight 750D, this adapter maintains a consistent mount fit and reliable mechanical connection. This extensive compatibility also means I could lend my adapter to friends or family who have Canon DSLRs without worrying about model restrictions, adding to its value as a versatile accessory.

To help visualize the key aspects of this adapter and how it aligns with my needs and expectations, I compiled the following summary

2. K&F Concept Pro Lens Mount Adapter Compatible for Canon FD FL 35mm SLR Lens to Canon EOS (EF, EF-S) Camera, Compatible with Canon 1D, 1DS, Mark II, III, IV, Digital Rebel T5i, T4i, T3i, T3

When I first came across the K&F Concept Pro Lens Mount Adapter, I was immediately intrigued by its promise to bridge the gap between classic Canon FD and FL 35mm SLR lenses and modern Canon EOS (EF, EF-S) mount cameras. As someone who appreciates the unique character and craftsmanship of vintage lenses but wants to use them on contemporary digital bodies, this adapter offers a compelling solution. Its compatibility with a broad range of Canon EOS cameras, from entry-level Rebels like the T3i and T5i to professional workhorses like the 1D and 5D series, means it can serve photographers at various skill levels and with different equipment setups.

One of the standout features for me is the built-in multi-coated focusing correction lens. This is crucial because adapting lenses with different flange distances often leads to issues with infinity focus. The fact that this adapter guarantees infinity focus or beyond is a testament to its precise engineering. The correction lens not only ensures sharp focus across the frame but also helps maintain image quality by reducing reflections and aberrations through multi-coating. This means I can rely on my vintage FD lenses for critical work without worrying about focus accuracy or image degradation.

Manual control is another big plus. Since FD and FL lenses are fully manual by design, having an adapter that supports manual focus and manual exposure keeps the shooting experience authentic and tactile. I enjoy the hands-on approach that manual lenses provide, allowing me to engage more deeply with composition and focusing. The adapter does not interfere with this experience; instead, it facilitates it seamlessly on modern Canon EOS bodies. This also means no electronic communication is lost, which is expected, but the adapter handles this well by ensuring mechanical compatibility.

I also appreciate the clear distinction the product makes regarding its compatibility. It specifically states that this adapter is for Canon FD mount lenses to EF mount cameras and is not interchangeable with EF mount lenses. This honest clarity helps avoid confusion and ensures that users purchase the correct adapter for their lenses. If someone owns EF lenses, they’ll know this isn’t the adapter for them, saving them time and frustration.

The extensive list of compatible cameras, including not only Canon DSLRs but also cinema cameras like the Blackmagic Pocket Cinema Camera 6K and Z CAM models, highlights the adapter’s versatility. For videographers who want to use vintage optics for their unique aesthetic, this adapter opens up creative possibilities. It’s reassuring to see support for both full-frame and APS-C format cameras, making it a versatile choice regardless of your sensor size.

It’s worth noting the detailed explanation about the infinity focus position adjustment. The small shift of the infinity mark to the positive side to accommodate temperature-induced focus shifts demonstrates the manufacturer’s attention to detail. This feature might seem technical, but it means that in practical use, I can trust the focus accuracy even under varying environmental conditions. However, it also reminds me to always double-check focus through the viewfinder when shooting at infinity, which is a small but important practice to ensure perfect results.

Overall, the K&F Concept Pro Lens Mount Adapter feels like a thoughtfully designed tool for photographers and videographers who want to marry the charm of old Canon FD/FL lenses with the convenience and advanced features of modern EOS cameras. It offers precision, reliability, and broad compatibility, making it a worthwhile investment if you’re looking to expand your creative toolkit. If you own Canon FD or FL lenses and want to continue using them without compromise, this adapter is an honest and effective choice that I would recommend considering seriously.

3. Fotasy Cannon FD Mount Lens to EF-M Mount Adapter, FD EFM Adapter, FD EOS M Adapter, Compatible with Canon EF M Mount Mirrorless Cameras EOS M M1 M2 M3 M5 M6 M6 Mark II M10 M50 M100 M200

When I first came across the Fotasy Canon FD Mount Lens to EF-M Mount Adapter, I was genuinely intrigued by its promise to bridge the gap between classic FD lenses and modern Canon EF-M mount mirrorless cameras. As someone who appreciates the unique optical qualities and character of vintage FD lenses, this adapter offers a practical and affordable way to breathe new life into my old glass, allowing me to use them seamlessly on my Canon EOS M series camera bodies like the M50 and M6 Mark II. The adapter’s compatibility with a wide range of Canon EF-M mirrorless models means that it’s quite versatile for users invested in this ecosystem.

One of the standout features of this adapter is its guarantee of infinity focus, which is crucial for landscape, astrophotography, and general shooting where precise focusing at long distances is required. This gives me confidence that my images will be sharp even when focusing far away, something that can sometimes be a concern with adapters. However, it’s important to be aware that the adapter is fully manual—meaning no electronic contacts are present. This means I have to manually adjust both exposure and focus on the lens itself. While this might initially seem like a limitation, I actually find it quite rewarding as it encourages me to slow down, understand my lens better, and engage more deeply with the manual photography process.

Since the adapter does not support automatic diaphragm control or autofocus, I have to rely on the aperture ring on my FD lenses and manually focus, which suits me well as I enjoy the tactile control and precision this gives. This is especially true when shooting in controlled environments or when I want to experiment creatively with depth of field. For photographers who love the hands-on experience and want to extend the usability of their vintage lenses without investing in costly new glass, this adapter is a great solution. It also means that I need to be comfortable with manual settings, so if you’re used to fully automatic operation, this might require a bit of a learning curve.

One crucial note that I appreciate the seller clarifies upfront is that this adapter is specifically designed for Canon EF-M mirrorless cameras only and will not fit Canon’s EF or EF-S mount DSLR cameras like the 5D series or Rebel T models. This clear distinction prevents any confusion and helps potential buyers avoid compatibility issues. If you own a Canon EOS M series mirrorless camera and have FD lenses lying around, this adapter can unlock a lot of creative possibilities without breaking the bank.

4. PHOLSY Lens Mount Adapter Manual Focus with Aperture Lever, Optical Glass and Cap Compatible with Canon FD FL Mount Lens to Canon EOS EF-Mount Camera Body, FD to EOS, FD to EF

When I first came across the PHOLSY Lens Mount Adapter Manual Focus with Aperture Lever, I was immediately intrigued by its promise to bridge the gap between vintage Canon FD and FL mount lenses and modern Canon EOS EF-mount camera bodies. As someone who appreciates the unique character and optical qualities of older lenses, this adapter offers a fantastic solution to continue using those cherished FD lenses on contemporary digital EOS cameras. The versatility of being compatible with both Canon FD and FL mount lenses, as well as Canon EOS EF mount cameras, means I don’t have to limit myself to one type of lens or camera system, opening up a wide range of creative possibilities.

One of the standout features that really impressed me is the inclusion of optical glass that allows for infinity focus without any compromise on image quality or focusing speed. This is crucial because many adapters tend to introduce some degree of optical degradation or limit focusing distances, but PHOLSY has thoughtfully addressed this. Although the adapter doesn’t transfer any mechanical or electronic signals—which means no autofocus or electronic aperture control—I actually find this to be a worthwhile trade-off. It encourages me to engage more deeply with manual focus and aperture control, enhancing my overall photographic experience and making me more deliberate in my settings.

The unique design element of the aperture lever is a game-changer for me. Many adapters ignore this aspect, forcing users to either lose aperture control or fiddle with makeshift solutions. Having a built-in aperture lever means I retain full manual control over the lens aperture just as if I were using the original mount, preserving the creative control and functionality that make FD lenses so appealing. This thoughtful design detail makes the adapter feel like an extension of my gear rather than a compromise.

Of course, adapting vintage lenses to modern bodies often raises concerns about build quality and durability. PHOLSY’s choice to construct the adapter from aviation-grade aluminum and copper reassures me of its robustness and longevity. It feels solid yet lightweight in my hand, and I trust it to withstand regular use without wearing down or damaging my valuable lenses and camera bodies. The precision engineering ensures a snug, light-tight fit that prevents any light leakage—something that can ruin images if overlooked. Smooth attachment and detachment make it convenient to switch lenses during shoots without hassle.

One point to keep in mind is the need to set the camera menu to “shoot with no lens attached” to ensure compatibility and proper functioning. While this is a minor extra step, it’s a small price to pay for the flexibility and creative freedom this adapter provides. In fact, once set up, I find the adapter lets me keep using the lenses I love on today’s most innovative camera bodies, blending the best of both worlds.

To summarize the PHOLSY Lens Mount Adapter’s key strengths and features, I’ve put together the following table which clearly outlines what makes this adapter a worthwhile investment for photographers like me who want to breathe new life into their classic lenses

Feature	Benefit
Compatibility	Works with Canon FD and FL mount lenses on Canon EOS EF mount cameras, expanding lens options
Optical Glass for Infinity Focus	Maintains sharp image quality and focusing range without degradation
Aperture Lever	Retains manual aperture control, preserving lens functionality
Build Material	Aviation-grade aluminum and copper provide durability and lightweight strength
Precision Fit	Ensures tight, light-proof connection and smooth lens mounting/dismounting
Manual Operation	No electronic communication, encouraging hands-on photography with manual focus and aperture

if you’re like me and have a collection of Canon FD or FL lenses gathering dust or simply want to explore manual focus photography with classic optics on your modern Canon EOS EF camera, the PHOLSY Lens Mount Adapter is an excellent investment. It combines solid construction, thoughtful design, and optical integrity to make vintage lenses practical and enjoyable to use today. While it requires manual operation and some camera menu tweaking, the creative control and image quality benefits far outweigh these minor inconveniences.

Buying Guide for Canon FD to EF Lens Adapters

Understanding the Need for a Canon FD to EF Adapter

When I first started exploring vintage lenses, I realized that my Canon FD lenses weren’t directly compatible with my Canon EF mount camera. That’s when I learned about Canon FD to EF adapters. These adapters allow me to use my older FD lenses on newer EF-mount cameras, preserving the unique characteristics of my vintage glass while enjoying modern camera features.

Compatibility Considerations

Before purchasing an adapter, I made sure to verify the compatibility between my lenses and camera body. Since Canon FD and EF mounts have different flange focal distances, the adapter must compensate for this to maintain proper focus. Some adapters are designed specifically for manual focus only, so if you want autofocus, it’s important to understand that most FD to EF adapters won’t support it.

Build Quality and Materials

I prefer an adapter made of sturdy metal rather than plastic. Metal adapters tend to be more durable and provide a snug fit between the lens and camera body. The quality of the connection affects both the safety of my equipment and the precision of focusing. A well-machined adapter also minimizes light leaks and maintains lens alignment.

Lens Functionality and Features

Since Canon FD lenses are manual focus, I knew I’d be focusing manually regardless of the adapter. However, some adapters come with a built-in aperture control ring, which is very helpful because my FD lenses have mechanical aperture rings that don’t communicate electronically with EF cameras. Choosing an adapter with aperture control ensures I can adjust the aperture smoothly without losing functionality.

Impact on Image Quality

I was curious if the adapter would affect my image quality. Generally, a good adapter won’t degrade the optical performance because it doesn’t contain glass elements. However, poorly made adapters might introduce slight misalignment or light leaks, which could affect sharpness and contrast. I always look for adapters with positive reviews regarding image quality preservation.

Price vs. Value

There are many adapters available at different price points. I balanced affordability with quality because a cheap adapter might cause wear or damage over time. Investing in a reliable adapter made me feel confident that my vintage lenses and modern camera body would work seamlessly together.

Additional Features to Consider

Some adapters include extra features like tripod mounts or extension tubes. While I didn’t need these for my setup, they could be useful depending on your shooting style. Also, some adapters have a locking mechanism to prevent accidental detachment, which adds extra security during use.

Final Thoughts from My Experience

Using a Canon FD to EF adapter opened up a whole new world of creative possibilities with my vintage lenses. By carefully considering compatibility, build quality, and functionality, I found an adapter that allowed me to enjoy the unique qualities of my FD glass on my EF mount camera without compromise. If you have old FD lenses, investing time in selecting the right adapter can truly enhance your photography experience.
