Hi everyone - long time lurker, but I do read these....and I have a question. Shooting a Canon 750D also labeled as the T6i. A year or so ago I bought an adaptor and was able to use my vintage Nikkor 35mm f2 lens. Obliviously manual only, but I liked the shallow depth of field and that I could really get close to the subject and the old glass has some nice characteristics.
Fast forward and a few weeks ago I bought a new Canon 50mm 1.8. Nice lens, but on a crop sensor camera it actually shoots like an 80mm lens.
Why does the ancient Nikkor glass permit me to get close up (within 6 inches) but the Canon require me to be feet away from the subject? Am I just imagining this?
It is in the design of the lens. How much adjustment in the distance focused is not inherent in a given focal length.
What's the minimum focus printed on each lens?
Does the adapter pushing the lens farther away from the camera, albeit a small distance, allow the closer viewing? (Mini extension tube.)
I have a Canon 50mm f-1.8 for my t2i. Printed on the lens is a minimal focal distance of .35m/1.1 ft, which I've found to be about right when used. My 18-55 mm gives me a 0.8 ft min distance but I prefer my for closeups. This does not make one better than the other, IMHO. The 50 has some advantages in sharpness and a different focal view. If you have a lens that performs better for what you want, then use it. It is not "better" necessarily, just more useful for you.
I have noticed that the same lens can focus closer if the camera is set to close up. I usually use autofocus, so that might not be true for manual, but you might try that. OR it might be that crop factor is changing how close you can focus also.

The answer to your question is the that the Nikon to Canon adapter moves the lens away from the plain of focus like extension tubes do. This distance is enough to allow closer focusing.

Slightly "too thick" adapters will NOT improve
the near focus limit. As an example, a [faulty]
adapter that doesn't allow distant focus past
10, 25, or 50 ft will only bring the near focus
limit down from about 18" to 17".
Acoarst, such too-thick adapters should be
returned to vendor for refund.

This is just plain wrong.
FWIW I do NOT doubt you have 40 years
of paid photo experience. Separate issue.
