only saw one person say that, and he was actually correct (all things
being equal the crop will have a slightly narrower depth of field).
Ugh,
you're completely wrong. It's been said a million time but I'm going to
say it again. In a situation where you are going to take a picture, you
need a certain subject framing. To achieve this framing, there are 2
variables, subject distance and lens focal length. To achieve the same
framing on a crop camera as you would have on a full frame camera you
need to either increase subject distance or use a wider focal length,
BOTH of which give you more depth of field.
If you are trying to
argue that you keep both subject distance and focal length the same
while taking the same picture, this is another one of your logical
fallacies. When you're taking pictures, you don't do this. You wouldn't
frame a 50mm composition with an 80mm equivalent lens just because
you're using a crop camera. You would either step back or you would use a
wider lens.
In every practical sense, the larger your sensor
is, the smaller your depth of field is going to be. This translates all
the way up to large format and all the way down to cell phone camera
sensors. Crop cameras do not magically break this rule. Crop cameras are
to full frame cameras what full frame cameras are to medium format
cameras.
What you're saying is just plain wrong. |
