The Nikon F Mount, with its DX and FX formats, is one of the most flexible and long-lasting lens systems ever created. First introduced in 1959 with the Nikon F SLR, this mount has supported decades of photographic innovation. Whether you’re a beginner exploring the DX format or a professional relying on FX for maximum quality, the Nikon F Mount offers a unique combination of heritage, adaptability, and modern performance.
As a photographer who has used this mount extensively in both formats, I can say it’s a system that delivers in every scenario, from casual shooting to professional work.
At its core, the Nikon F Mount is a bayonet-style lens mount designed for Nikon’s DSLR and film cameras. Its 44mm diameter and 46.5mm flange distance make it highly versatile, supporting everything from ultra-wide-angle lenses to powerful telephotos.
The mount supports two sensor sizes:
Both formats use the same mount, which means DX lenses can be used on FX bodies (with some limitations) and FX lenses can be used on DX bodies (with a crop factor). This flexibility is one of the system’s greatest strengths, allowing photographers to build a lens collection that works across multiple camera bodies.
Nikon’s DX format was introduced in 1999 with the Nikon D1, marking the brand’s entry into digital SLRs. Designed for smaller APS-C sensors, the DX format is ideal for photographers who want a lightweight, affordable system without sacrificing image quality.
The compact size of DX cameras, like the Nikon D7500 or D5600, makes them perfect for travel, wildlife, and everyday shooting. Paired with DX-specific lenses, these cameras offer excellent reach due to the 1.5x crop factor. For example, a 200mm lens on a DX body provides an effective focal length of 300mm—perfect for capturing distant subjects.
One of my favorite DX lenses is the Nikon AF-S DX 16-80mm f/2.8-4E ED VR, a versatile zoom that’s sharp, lightweight, and great for both landscapes and portraits.
The FX format, introduced with the Nikon D3 in 2007, brought full-frame sensors to Nikon’s digital lineup. FX cameras like the Nikon D850, D6, or D780 deliver stunning image quality, with better low-light performance, dynamic range, and shallower depth of field compared to DX.
The FX format is perfect for professionals and serious enthusiasts who demand the best. Whether you’re shooting weddings, landscapes, or commercial work, FX cameras and lenses deliver exceptional results.
One of my go-to FX lenses is the Nikon AF-S 24-70mm f/2.8E ED VR, a fast and sharp zoom lens that’s a workhorse for many types of photography.
One of the greatest strengths of the Nikon F Mount is its backward compatibility. You can mount lenses from the 1960s onto modern DSLRs, and they’ll still work (with some limitations in metering and autofocus). This makes the F Mount a treasure trove for photographers who enjoy experimenting with vintage glass.
Nikon offers lenses for every type of photographer:
Some standout lenses include:
Over the years, I’ve used both DX and FX cameras extensively, and what I love most about the F Mount is its adaptability. As my photography evolved, I could upgrade from DX to FX while still using the same lenses. The mount’s compatibility has allowed me to explore a wide range of lenses, from modern zooms to vintage primes, each offering its own unique character.
The DX format was my starting point, offering a lightweight kit that I could take anywhere. As I moved into more professional work, the FX format became my go-to for its superior image quality and flexibility. What stands out is how seamless the transition was—no need to start from scratch with new gear.
While the F Mount is incredibly versatile, it’s not without its limitations. Autofocus performance on older lenses can be slow compared to modern mirrorless systems, and the optical designs of some legacy lenses may not match the sharpness of newer glass. Additionally, the weight of some FX lenses can be a challenge for those prioritizing portability.
With Nikon’s shift to the Z Mount for its mirrorless cameras, the F Mount’s future is uncertain. However, the FTZ adapter ensures F Mount lenses can be used on Z cameras, extending the life of this legendary system.
Despite the rise of mirrorless systems, the Nikon F Mount remains a cornerstone of photography. Its extensive lineup of lenses, reliable build quality, and backward compatibility make it a system that appeals to both new photographers and seasoned professionals.
For me, the F Mount isn’t just a lens system—it’s a legacy. It’s a bridge between generations of photography, a testament to Nikon’s commitment to excellence. Whether you’re shooting on a DX body or an FX powerhouse, the F Mount has something to offer, delivering the tools you need to create stunning images.
If you’re looking for a system that combines heritage with performance, the Nikon F Mount is a choice you won’t regret.
