Both lenses are 35mm f/2 primes, a classic wide-normal focal length for street, travel and documentary work, but they come from different mount families. Choose the Nikon 35mm f/2 if you shoot a Nikon body or want flexible adapting options, and choose the Canon FD 35mm f/2 Concave if you enjoy older manual lenses on a mirrorless camera through an adapter. We have not used either, so confirm details before buying.
What Each Lens Is
The Nikon 35mm f/2 exists in several generations, including manual-focus versions and an autofocus version for F-mount cameras. The versions differ in how they connect to the body, so check which generation you are looking at.
The Canon FD 35mm f/2 Concave is an older manual-focus lens from Canon’s FD system, named for the concave front element in its early optical design. It was made for Canon’s film SLRs. It does not mount directly on modern Canon digital bodies, which use a different mount.
Differences That Matter
- Mount family: Nikon F lenses fit Nikon F-mount bodies directly and can be adapted to many mirrorless cameras. FD lenses need an adapter on most mirrorless bodies, and FD adapters are widely available because of the short distance from mount to sensor.
- Focus: the FD lens is manual focus only. Some Nikon versions offer autofocus on compatible bodies, while manual versions need focus aids.
- Aperture control: older manual lenses often use a ring on the lens. Adapted use frequently requires stopping down by hand or setting the camera to a mode that works with manual lenses.
- Character: older designs tend to have softer corners wide open, more flare and a distinct rendering. Some photographers like that, others prefer a modern look.
- Condition: vintage lenses may have haze, stiff focus rings or worn coatings. Inspect any used copy carefully.

FAQ
How do I focus a manual lens on a mirrorless camera?
Turn on focus magnification or focus peaking if your camera offers them. At f/2 and a subject distance of a few meters, depth of field is thin, so take your time.
Is 35mm good for portraits?
It suits environmental portraits that show the setting. For tight head shots, longer lenses flatter more.
The Short Version
Both lenses give the same focal length and aperture, but they serve different shooters. The Nikon is the easier choice on Nikon bodies, while the Canon FD Concave is a manual, adapted option for people who enjoy vintage glass.
