What is the hyperfocal distance at 50mm f/8 on full frame?
At 50mm, f/8, on full frame, the hyperfocal distance is roughly 10.88 meters (35.7 feet) — far enough out that hyperfocal focusing stops being a practical landscape technique at this specific focal length and aperture and starts being closer to an abstract textbook reference point.
Why 50mm Makes Hyperfocal Focusing Impractical
Because hyperfocal distance grows roughly with the square of focal length, 50mm's hyperfocal distance at f/8 is over four times 24mm's, even though the focal length only a little more than doubled. In real shooting, few landscape or street compositions have their nearest subject sitting almost 11 meters away, which is exactly why hyperfocal technique is discussed almost exclusively in the context of wide-angle lenses rather than a 50mm normal lens.
What Changes This Number
Stopping down considerably — to f/16 or narrower — brings the hyperfocal distance back into a more workable range, at the real cost of diffraction softening on most sensors. A crop-sensor camera needs a shorter real 50mm-equivalent focal length to match the same field of view, which changes this figure independently of the aperture choice.

Frequently Asked Questions
Should I still bother with hyperfocal focusing at 50mm?
Rarely for landscape work specifically — at f/8 the hyperfocal distance is nearly 11 meters, well beyond where most compositions place their nearest important subject, so simply focusing directly on your actual subject and accepting a narrower depth of field is usually the more practical approach at this focal length.
What aperture would bring 50mm's hyperfocal distance closer to what 24mm gives at f/8?
You'd need to stop down considerably, into the f/16-f/22 range, which brings real diffraction softening on most sensors — a strong signal that 50mm simply isn't the right tool of choice for maximizing front-to-back sharpness the way a genuinely wider lens is.
