Is Canon EOS 60D ‘noisy’?
I am using a Canon 60D for the
last 1.5 years. Using the 60D at ISO
640 (and above) is showing a good
amount of noise. Is my 60D not
capable of doing high ISO shots?
Or what might be the problem?
I’m using the kit lens 18-135mm IS
STM.
Aravind V. S, via emailAfter receiving Aravind’s email, I
requested him to send us few images
taken with the Canon EOS 60D that he
considers noisy. Those images range
from ISO 500 to ISO 1250.
In my opinion, all the images we
received are usable. Yes, I do see noise
in all of them but the question is, is
the noise at acceptable level or is
the noise unacceptable? While what
is acceptable and what is not is also
subjective and varies from person toperson, we must realise that noise is
a part and parcel of all digital images.
Underexposed areas (dark shirts, dark
faces, dark backgrounds) have little or
no detail (lack of image information/
data) and hence will always show
noise, irrespective of the ISO used (and
higher ISO images will of course show
more noise).Another point to consider is the
enlargement factor. If you try to look
for noise at higher enlargements (say
50%, 100%) you will notice more
noise; the same image at ‘normal’
viewing size may show very little to no
noise.Also consider this. An image that
appears noisy on the computer
monitor, will exhibit lesser noise
when printed. The type of printing
(commercial lab printing, inkjetCamera: Canon EOS 60D; ISO: 1250Ask your question to Uncle at [email protected]
printing, magazine printing) will all
show different amount of noise. The
texture of the printing paper (glossy,
matt, canvas) is also important; glossy
prints will show more noise, canvas,
the least.Finally, do bear in mind that the EOS
60D was introduced around mid-- It would not be fair to compare
5-year old technology with the current
technology.
A Query on Nikon’s
200-500mm lens
I have gone
through the
review article
on the above
referenced
lens, published
in the Nov.
issue of SP.
Please clarify
the following
points:It ( the review)
says, “Nikon
claims that the
VR has a 5-stop
advantage”. It
also mentions
that “The lens
is not very easy
to hand-hold
for more than
a few seconds.
You need a very
heavy duty
tripod....”. While
using tripod
(which, as it
appears, in this
case, I will need all the time), I have
to switch-off the VR! Then what is
the use of VR at all? Please tell meAF-S Nikkor
