Respected Gurcharan Sir,
Both of these lenses which you have mentioned will not give results as
good as a professional macro lens compatible to your camera. These
lenses are nothing but magnifying glasses, you may use more than one
at a time, It brings a buldge in the central area of the image, and
secondly, on the periphery of the image there will be aberration too.
To avoid this you can use lower apertures but with good flash but
still it will not have that quality as that of professional lens.
Just if u wish to check how good your lenses is working, make squares
on inset, on the paper, and take a picture, from as close as you can
get to it. then check in the image whether the squares are looking
like squares, i.e., do they have straight lines or curved?
For your camera model, you have only two options of macro lens from
Sony, but these lenses are too costly (You may check in grey market
for lower price):
1. SAL100M28 - 100mm F2.8 Macro, minimum distance 35cm and image size
will be 100% (59,000/-).
2. SAL50M28 - 50mm F2.8 Macro, minimum distance 55cm and the image
size will be 50% (39,990/-)
"image size will be 100%" - this means, when you focus the image at
the closest distance, what you see in the viewfinder will be 100% of
the actual size of the subject.
A good ring flash which can be used with any of the lenses you have
mentioned as well as the two i suggested will cost around 6000/-
