Hi,
This is perhaps quite simple for many of you.
I think about it and I am not that sure. I tell
you a bit about it.
A medium format 50 mm. or a 50 mm. f/1.4 lens
from Zeiss has a minimum focusing distance
at 45 cm. or 50 cm. A macro lens with the
same focal length can focus as close as 25 cm.
However, in a time that many cameras come
with an excess of megapixels, is it right to say
the following:
A man uses a Nikon D800 with a 50 mm. lens,
not the macro version. He focuses as close
as posible and takes a picture with the maximum
resolution, some 36 MB. The salad plate he
photographed has quite a bit of space to the
edges. So, the edges are trimmed off. The
actual "weight" of the picture after the trimming
is approximately as big as a shot taken with a
50 mm. macro lens and 5D Mark III at maximum
resolution, some 24 MB. Would this be more
or less correct??
...Show more →I assume you mean MP as in Mega Pixels vs MB as in MegaByte.
It means, one does not need by all means a
macro lens, one can crop off the picture (if one
has enough megapixels)!
Thank you, kind regards,
igmolinav : ) !!!
It really would depend on the sharpness of the lenses in question as to how sharp each image would be, and there will be POV differences, DOF differences, and possibly resolution differences due to the optics.
So, yes, in theory you could get similar images from each, just not identical.
Cropping changes the FOV just like using a crop sensor.
Are you trying to talk yourself into or out of a new camera and or lens?
