why we must have good knowledges first about lens, so we can buy the best lens
that suitable for you, Of course you don’t want to waste your money to buy lens
for something useless.
Every

you a guides for who’s still confuse to choose the canon & Nikon lens.
Types of DSLR Lens
Firstly,
i divide DSLR lens in 2 main type, they are Prime Lens/ Fix Lens and Zoom
Lens
Prime Lens/Fix Lens
Prime
Lens have fix focal lenght, so absolutely the subject of the photo can’t be
enlarged nor minimized. We have to move
our position if we will to measure the the object size nor the point of view.
This lens usually have size smaller that zoom lens ( comparing with the same
focal lenght). But even small the photo
result will mor e sharp. Prime lens also have wide aperture , it makes good blurred/bokeh. Some types of this lens
such as :
Zoom Lens
Zoom
lens have different focal lenght that we can set suitable with what we want, so
it’s reverse from Prime Lens. The advantage of zoom lens is flexibility, it means that just using one
lens we can get many variants of focal lenght
& lens anglewithout move our
position oftenly. While the wakness of zoom lens are the size is bigger and
more heavy also the sharp/depth quality of photo still under of Prime Lens.
Some Types of this lens such as :
Zoom
Lens oftenly are equipped by information about ratio of zommed in, but need to be
understand that zoomed in this case is the comparison between smallest with the
biggest focal lenght. So, it’s not about
photo zoomed from the the real object. For example EF-S 15-85mm f/3.5-5.6 IS
USM, ratio of zoomed in is 85:15 or 5.6:1.
Second,
i will divide in sub lenses, there are Ultra Wide Lens, Wide Lens, Standard
Lens, Tele Lens, and Super Tele Lens.
Ultra Wide Lens
The wide of field of view in this lens is more than 90° . If we look at focal lenght , it‘s between 8mm-20mm.Most of them is used for landscape photograph and interior.

Third,
i will talk about the types of sub lens for special needed, they are Macro
lens, Fisheye Lens, Soft Focus Lens, and Perspective Control Lens. Usually,
this lens has been labeled with special code by Lens Company.
Macro Lens
Macro
Lens was designed to shoot small and close/near things. Therefore Macro Lens
must have close/near focal lenght.The comparison of photo object with picture
captured on censor usually 1:1, it means that when focus on very close with the
photo subject ,the the size of photo subject is the same with the picture
captured on camera/fim censor.
Fisheye Lens
Fisheye
Lens is lens which is have the extreme wide-angle . Moreover there’s lens that
have pointview untill 180°. Beside that, Tis lens also have extreme distortion.
Why it’s called Fish eye, because it’s alike eye of fish.
Perspective Control
Lens
This
Lens is used for architectural photographs, There’s not much photographer who
use this lens type because it’s too specific. Tili-Shift lens is one of this
lens types.
