CANON LENSES AND LENS NIKON
When going to buy a DSLR camera, generally addressed to the selection of the ease and availability of lens options later. Then
it's top DSLR manufacturers such as Canon and Nikon remains a favorite
of photographers, because its lens lineup is very complete. Well
that Pentax, Olympus, Sony (Minolta) also has a collection of lenses is
complete, but sometimes the owners of DSLR also be tempted to buy
alternative lens like the Sigma / Tamron / Tokina and in fact the
alternative lens like this is not much supply of lens options with
mounting aside version Canon or Nikon.
DSLR camera lens is divided into several kinds. The simplest is a one of its kind, which is a fixed lens (fixed / prime) and a zoom lens (variable focal range). The
zoom lens will also be divided into two, namely the opening of constant
(fixed f / 2.8, fixed f / 4, etc.) or the opening of variables (shrink
when zooming). From
the size of the diameter of the lens there are also two kinds of DSLR
lenses, ie lenses for film SLR / DSLR full frame and lenses with a
smaller diameter (for APS-C). In
terms of lens technology is also divided into two, with a focus motor
(and micro-chip) in the lens and without the focus motor (long lens). With so many of these differences, it is natural that the
photographers beginners (like me) to the confusion in the lenses on the
market, let alone the price can vary from one million to tens of
millions.
Just
knowing Canon and Nikon lens lineup, I present a list of head-to-head
favorite lens of the photographer along with a little review. But first, I present the first term or terms of both and not get confused:
The
size of the diameter of the lens: Canon uses the term EF and EF-S, note
that the code EF showed a large diameter (for a film SLR and DSLR Full
Frame) while the EF-S is for APS-C image circle is smaller. Likewise, Nikon lenses, which means that only the coded DX for Nikon DX cameras only. Nikon lenses without a code DX means it can be used in the film
Nikon SLR or DSLR Nikon full-frame (although in DSLR Nikon DX can still
be).
Technology: Canon has a lens with a focus motor in it, but not all of them wearing a USM focus motor (Ultra Sonic Motor). Motor USM renowned for its subtlety, speed and accuracy. Canon lens with USM technology is relatively expensive. Instead,
all lenses Nikon AF-S technology there must be a focus motor SWM
(Silent Wave Motor), while the long lens Nikon AF or AF-D no bike. Although all lens AF-S SWM no motor, but the motor performance was not the same between the lens and the lens's expensive. Motor SWM's lens slower and smoother.
Optical
Image Stabilizer: Both Canon and Nikon implemented a system stabilizer
on the lens, which means that not all lenses have this feature. The
way it works is gyro-sensors inside the lens detect hand-shake and
compensate by moving a special lens elements so that a photo taken at a
low speed (and / or telephoto position) to avoid the risk of blur. Canon's naming system to the IS code, while Nikon VR wear code. Both IS and VR, both to show a stabilizing effect on the optical viewfinder, before the photo is taken.
Caste: In lens Canon lenses are two castes, namely ordinary lenses and lens Luxury (L series, marked red bracelet diujungnya). Nikon does not distinguish between caste on the lens, it's just a new
Nikon lens is simplified by eliminating the aperture ring, marked with
the code G (gelded).
Prime lens / fix
Have
a fixed lens sharpness unmatched by a zoom lens, with openings which
are generally large, making it suitable for portrait photos with bokeh
charming. Canon
and Nikon both have a complete line of fixed lens, with a focal ranging
from wide (approximately 20mm), normal (about 50mm) to telephoto (about
100mm). Note that all fixed lens Canon EF-coded, with some wearing L code and USM.
Some of the elite class of fixed lens Canon is:
EF 24mm f / 1.4L USM
EF 50mm f / 1.2L USM
EF 85mm f / 1.2L II USM
While
Nikon has a line of prime lenses whose maximum aperture at f / 1.4 as
the newly launched and is compatible with the D40, the AF-S 50mm f /
1.4G. While the fixed lens economical and favorites from Canon is the EF 50mm f / 1.8, and from Nikon is the AF 50mm f / 1.8D. In
addition, Nikon also has prime is wide as AF 14mm f / 2.8D ED (update:
Nikon launches prime AF-S 24mm f / 1.4 in 2010) and prime tele such as
AF 85mm f / 1.4D IF, and prime micro like AF-S 105mm f / 2.8D ED VR. Speaking of telephoto prime lens, both Canon and Nikon have a complete
range telephoto lenses ranging from 135mm, 180mm, 200mm, 300mm, 400mm,
500mm and 600mm (Canon even had a 800mm and 1.200mm), some equipped with
IS or VR.
Zoom lens: wideangle
When
the fixed lens does not provide flexibility to change the focal
position, the zoom lens focal enable us to change in a certain range so
that it can obtain a wide variety of compositions (and avoid frequent
back and forth). Wideangle
zoom lens generally begin from 14 to 24mm, but note when used in the
camera with a crop factor (1,6x Canon APS-C, 1,3x Canon 1Ds and 1.5x for
Nikon), the focal length will change much. Therefore, lens manufacturers must try extra hard to design a very
wide lens so that when exposed to the crop factor, the lens is still
worth mentioning the wide lens.
For
wideangle photography needs such as landscape and architecture, users
of Canon's APS-C sensor is only able to enjoy a wide lens EF-S 10-22mm f
/ 3.5-4.5 USM, sementar users can try Nikon DX lens AF-S DX 12-24mm f /
4G IF ED. For users of Nikon Full frame, provided Nikon AF-S 14-24mm f / 2.8g ED. Unfortunately not yet available from the Canon EF lens commensurate with the Nikon 14-24mm f / 2.8 this.
Zoom lens: standard
Standard
zoom range is a safe range, with a wide and telephoto capabilities are
sufficient enough so as to travel with only carry one lens only. Good news for users of Nikon DX lenses for Nikon DX provided a lot
of quality and affordable (such as D40 18-55mm kit lens), including:
AF-S DX 16-85mm f / 3.5-5.6G ED VR
AF-S DX 17-55mm f / 2.8g ED IF (constant aperture)
AF-S DX 18-70mm f / 3.5-4.5G IF ED (kitnya D70)
AF-S DX 18-105mm f / 3.5-5.6G VR (kitnya D90)
AF-S DX 18-135mm f / 3.5-5.6G IF ED (kitnya D80)
AF-S DX 18-200mm f / 3.5-5.6G ED IF VR (broom universe)
Availability
of many lens options standard DX cheap and quality is what makes many
photographers are non professional select Nikon digital SLR cameras,
although many of these options also criticized some observers because of
the large overlap in the ranges of lenses and generally has the lens
aperture is similar (should Nikon started making lenses standard constant aperture of f / 4).
As for Canon APS-C users that need a lens EF-S seems to be quite
patient because while this is only available following EF-S lenses
(excluding 18-55mm):
EF-S 17-55mm f / 2.8 IS USM (constant aperture)
EF-S 17-85mm f / 4-5.6 IS USM
EF-S 18-200mm f / 3.5-5.6 IS (broom universe - non USM)
Conditions
were turned away when we saw the ranks lens Full frame, which Canon has
a characteristic by providing two lens options for the series EF his,
namely lens aperture constant fast (f / 2.8) and lens aperture constant
economical (f / 4). While Nikon only provides fast aperture lens f / 2.8 is expensive only. Update: Nikon has finally launched with a lens aperture of f / 4, namely AF-S 16-35mm f / 4 VR.
Canon EF lenses standard favorites:
EF 16-35mm f / 2.8L ISM
EF 17-40mm f / 4L USM
EF 24-70mm f / 2.8L USM
EF 24-105mm f / 4L IS USM
Meanwhile, as the equivalent, in the ranks of Nikon also has two standard zoom lens that is a favorite:
AF-S 17-35mm f / 2.8D IF ED
AF-S 16-35mm f / 4GG ED VR (new, updated)
AF-S 24-70mm f / 2.8g ED
For
the record, there are many other lenses from Canon EF or Nikon DX's non
standard ranges such as 28-80mm, 28-105mm and 28-200mm, but because of
this stems from a 28mm lens, then when exposed to the crop factor would
be unusual (about 43mm) so unpopular Canon DSLR users or Nikon APS-C DX.
Zoom lens: tele
We start in class APS-C or class DX. Nikon
is famous for telenya economical lens, the AF-S DX 55-200mm f / 4-5.6G
IF-ED VR while Canon offers a longer telephoto capabilities with the
EF-S 55-250mm f / 4-5.6 IS. Canon itself actually has a legacy lens with a 55-200mm range but not EF-S.
Further,
in Full-frame class, the competition head-to-head balanced occurred in
two classes, 70-300mm and 70-200mm class constant aperture. Canon
has EF 70-300mm f / 4-5.6 IS USM and Nikon has AF-S 70-300mm f /
4.5-5.6G IF ED VR both of which are favored by many photographers
because it affordable and ability telenya pretty much at 300mm (450mm
equivalent ). At
constant aperture lens 70-200mm class, inequality occurs when Nikon
only has one lens products must compete with four (yes, four) Canon
70-200mm lens. Relying Nikon AF-S 70-200mm f / 2.8g ED IF VR while Canon has four options, namely:
EF 70-200mm f / 2.8L IS USM (fast, plus IS)
EF 70-200mm f / 2.8L USM (fast, without IS)
EF 70-200mm f / 4L IS USM (savers, plus IS)
EF 70-200mm f / 4L USM (most frugal, without IS)
While for purposes telephoto zoom lens specifically both Canon and Nikon also has a range that is not common like:
Canon EF 90-300mm f / 4.5-5.6 USM
Canon EF 100-400mm f / 4.5-5.6L IS USM
Nikon AF 80-400mm f / 4.5-5.6D ED VR
Nikon AF-S 200-400mm f / 4G IF ED VR
Well, that several rows of lenses from Canon and Nikon. Both lens selection was quite complete, so no wonder many professionals who glanced DSLR from Canon or Nikon. It's
just that we have to look at the needs of our lenses (before buying a
DSLR), when it needs to be specific then choose one lens DSLR camera
would not be a problem. Once we determine the brand of the camera, then we will be bound to semerk systems, such as the lens and the flash.
In closing, the following brief summary of the above review:
Canon and Nikon both have a complete fixed lens
In grade wideangle zoom lens, Nikon has a more complete collection
In class standard zoom lens, Nikon is more complete in-class DX
lenses, while the Canon is more complete in the classroom full-frame
lenses
In class telephoto lens, Canon and Nikon both have a complete collection (note Canon 70-200mm has four variants)
Nikon is not much had a constant aperture lens f / 4 (such as the AF-S DX 12-24mm f / 4G IF ED)
To get the highest optical performance (plus USM technology) of Canon lenses, can be obtained from the Canon L series lenses.

FUNGSI DIAFRAGMA ATAU F PADA KAMERA DSLR/SLR
pada umumnya lensa ada yang memiliki bukaan terbesar
dengan bilangan f/4. Pada bilangan tersebut diafragma sedang dibukan
pada ukuran diameter mencapai 25mm. Lambang f berarti melambangkan
panjang fokus dari lensa, sedangkan angka 4 melambangkan diamtere
entrance pupil. Angka-angka bukaan Aperture yang sering dipakai pada
perancangan lensa fotografi dari yang terbesar adalah f/1.0, f/1.2,
f/1.4, f/1.7, f/1.8, f/2.0, f/2.5, f/2.8, f/3.5, f/3.8, f/4, f/4.5 dan
seterusnya. Sedangkan untuk bukaan terkecil pada umumnya bisa mencapai
f/18, f/20, f/22, f/32, dan seterusnya jika memungkinkan bilah bisa
menutup lebih kecil. Sebagai catatan semakin kecil angka relative
Aperture maka semakin besar bukaan diafragma.
Fungsi Aperture
Mari kita mengenal fungsi Aperture pada kamera yang ternyata sangat berpengaruh pada hasil foto atau bahkan kualitasnya.
Mari kita mengenal fungsi Aperture pada kamera yang ternyata sangat berpengaruh pada hasil foto atau bahkan kualitasnya.
- Mengontrol cahaya yang masuk
Fungsi utama dari Aperture tentu adalah
mengontrol seberapa cahaya yang bisa masuk ke dalam sensor. Mengapa bisa
mengontrol cahaya? Kembali lagi pada pengertian Aperture yang merupakan
lubang pada bidang diafragma untuk tempat berlalunya sinar luminasi.
Semakin besar pengaturan bukaan Aperture maka semakin memungkinkan
banyak cahaya yang masuk sensor. Dan sebaliknya, semakin kecil bukaan
maka semakin sedikit cahaya yang dapat masuk. Itulah mengapa dalam
perumusan Exposure Value, Aperture menjadi yang terpenting selain
pengaturan Kecepatan rana dan ISO.
- Mengontrol kedalaman ruang sempit dan lebar
Pengaturan kedalaman ruang sebuah foto
atau Depth of Field 100% hanya bisa diatur dengan Aperture. Kedalaman
ruang menjadi penunjuk sebuah ruang tertentu di dalam gambar yang nampak
relatif tajam karena adanya perbedaan ketajaman atau fokus. Istilah
dalam forografi masa kini adalah “foto bokeh” dimana satu subjek lebih
tajam, sedangkan background maupun foreground tampak buram atau tidak
fokus apabila Anda mengatur Aperture sebesar-besarnya seperti angka
f/1.4, f/1.8, atau f/2.8. sedangkan untuk mendapatkan ketajaman
keseluruhan pada objek, maka pengaturan Aperture harus lebih kecil
mencapai f/10, f/16, f/22 dan seterusnya. Jadi sederhananya, pada
pengaturan angka bukaan yang besar menghasilkan efek ruang ketajaman
yang berkurang (cocok untuk foto portrait atau foto subjek tunggal).
Sebaliknya apabila angka bukaan yang mengecil akan menghasilkan efek
ruang ketajaman bertambah luas (cocok untuk foto landscape maupun
group), maka semakin kecil f yang diatur maka ketajaman dari foto akan berkurang dan semakin tinggi f maka hasil foto akan semakin tajam.
- Menghasilkan difraksi
Pada hukum fisika, cahaya dipastikan
akan mengalami difraksi saat melewati lubang sempit. Difraksi sendiri
berarti penyebaran gelombang cahaya yang dihasilkan karena ada halangan.
Lubang sempit dalam konteks ini tentu adalah Aperture yang diatur
dengan relative Aperture atau bukaan. Jadi ketika Anda mengatur Aperture
terkecil (nilai tinggi) seperti f/10, 1/16, f/22 dan seterusnya, maka
akan menghasilkan efek starbrust pada objek yang memiliki sumber cahaya.
Efek difraksi akan sangat terlihat ketika Anda memotret lampu pada
malam hari. Semakin besar angka f-number Aperture maka semakin luas
penyebaran efek difraksi yang dihasilkan.
- Mempengaruhi kecepatan lensa
Pada lensa fotografi yang diatur dengan
diameter Aperture lebih besar (nilai bukaan kecil) dianggap lebih cepat
karena lensa tersebut mampu meneruskan intensitas cahaya lebih besar
terhadap permukaan bidang fokal. Inilah yang nantinya dapat memungkinkan
untuk melakukan pemotretan kecepatan rana lebih tinggi. Berbeda dengan
lensa fotografi yang diatur dengan diameter diafragma lebih kecil (nilai
bukaan besar) dianggap lebih lambat disebabkan intensitas cahaya yang
diteruskan oleh lensa relatif lebih kecil sehingga dibutuhkan exposure
dengan rentang waktu yang lebih lama (kecepatan rana) agar foto
dimungkinkan tidak underexposed. Fungsi Aperture pada kamera ini lebih
erat kaitannya dengan fungsi pertama.
