Question
of the MonthAP
I am a regular reader of the magazine and have a
few questions that I would like to have answered. I
use Nikon D3300 with two lenses, the 18-55mm f/
3.5-5.6 and the 35mm f/1.8.
I want to know two things:
1) If I take a picture at 35mm f/8 and maintain
same ISO, Shutter Speed, will the result be exactly
same on both the lenses mentioned above? I tested
it and I got no difference on my
computer. But I want to under-
stand it clearly.
2) As we want to get more depth
of field for landscape photogra-
phy, then why will I buy a costly
f/1.4 wide lens? What is the exact
perspective of ‘Fast Lens’ in wide?

KolkataDear Dipanjan,
It is interesting that you have asked this question.We tested some lenses recently and used a similar
technique to check distortion on the two lenses. So I
am going to answer the question below:- The answer in simple is No. But if you shoot at
f/8 then there will be a very minute difference and
this also might not be visible since it depends on your
computer screen as well. The reason for the same is
that there are two things that will affect the picture
quality, one is the camera, which in your case is the
same, and the second is the optics and the aperture of
the lens. In case of the F/1.8 the colour, saturation and
some other things might be the same, but the details
in the image quality on zooming in will be higher as
compared to the f/3.5-5.6.
I am assuming that both the lenses are also Nikkor
lenses. In case if you were to use two different lenses
from two different manufacturers then the cases in
saturation and colour would also be different. Since
f/1.8 is a wider aperture and has lesser lens elements,
it will allow more light to be captured by the sensor,
there is a higher amount of details that is capture in
the lens.
