Saya tau topik ini dulu pernah dibahas dan saya juga tahu perbedaan keduanya (Lensa Nikkor D dan G) yang paling gampang dilihat.
Tetapi yang menjadi pertanyaan saya adalah begini. Beberapa waktu yang lalu saya melihat 2 lensa:

• Nikkor 1,4/50mm dengan ciri-ciri: mempunyai aperture ring dan di bodynya ada tulisan huruf "D". beratnya 230g.
• Nikkor 1,4/50mm dengan ciri-ciri: mempunyai aperture ring juga tapi tidak ada tulisan huruf "D" di bodynya. beratnya 220g.

tidak hanya di lensa 50mm saja, tapi juga di beberapa lensa lain. sama jenis tapi kok beda.
Apakah lensa yang tidak ada tulisan huruf "D" nya itu juga masih termasuk type lensa Nikkor D ?? Kalau bukan, apa dong?
untuk bantuannya saya ucapkan terimakasih.

D itu artinya Distance.
Kalau type G itu gak ada gelang Aperturenya.

Baca sendiri di SINI yach...gua lagi enggak mood mau ngetiknya...(:|

Mau beli lensa ya? ;;)

mas Setiadi: saya sudah baca, thanks utk infonya. tapi pertanyaan saya, yang saya cetak miring, masih belum terjawab.

Suryo : kalau kamu baca lebih teliti pasti pertanyaanmu terjawab.

AF-D; "D Type"
Another very subtle improvement you may safely ignore.

These lenses supposedly let the camera know the distance at which the lens has focused.

In very rare instances supposedly it helps the matrix meter, especially with flash, determine the exposure more accurately. KenRockwell.com has tested AF-D vs AF lenses and found no difference, even in difficult flash situations. The only improvement is if you want to photograph straight into mirrors. Without a D lens you'll get underexposure because the image of the flash in the mirror fools the meter into underexposure. With D lenses you'll get a properly exposed image of a bright flash. I've expended film on this foolishness so you don't have to.

I ignore this feature, so you can too. If you are buying used lenses you can get the earlier non-D versions cheaper. Don't worry here. In fact, the instruction manual of the 105mm f/2.8D AF Micro-Nikkor cautions that the D feature of the lens can lead to the WRONG EXPOSURE unless you keep your flashes at the same distance from the subject as the film, which is a real obstacle to creativity.

There are a couple of ways to signify a "D" lens: Nikon usually marks its lenses as "50mm f/1.4D AF" as opposed to "50mm f/1.4 AF-D," but it all means the same thing.

All AF-D lenses are AF and AI-s, and work great on manual focus cameras. You'll need to have a coupling prong added for use with the meter on ancient pre-AI cameras.

Focusing speed has nothing to do with whether or not a lens is D. Of course newer lenses are D and newer lenses tend to focus more quickly, but the focus speed is determined by the gearing between the AF coupler and the focus ring, not the D feature.

D lenses help the meter a little bit in guessing what you are trying to photograph. It has very little effect. Because impressionable people mistakenly believe that D lenses serve some wonderful purpose you can get the perfectly good non-D lenses cheap today used. In making deliberate tests of D and non-D lenses with the same subject at the same time I have seen no differences. The only time I've seen a difference is doing the one thing for which they are good: making of flash photos straight into a mirror. The only non-D AF lens made today is the fine 50mm f/1.8 AF. It is a bargain. 3D meteriing may safely be ignored.

mas Suryo, kalau anda tertarik, anda bisa membaca artikel berikut yg membahas ttg sejarah lensa Nikon, mudah mudahan bisa menjawab pertanyaan anda

Nikkor Lenses, a little personal opinion

Wah...selama ini saya cuma tinggal pakai..Sungguh deh, aku tak tahu detil lensa Nikkor yang saya pakai. Yang ED dan yang EDD aja aku gak tahu bedanya.....

Masih bingung atau tambah bingung? 8-} :D

Suryo :

Di dunia Nikon itu ada fasilitas 3D Multi-sensor Balanced Fill-Flash. Yang bisa berfungsi bila HANYA menggunakan lensa type D atau G. Jadi selain type itu tidak bisa.
Apa artinya D itu adalah Distance. Seingat saya lensa bertype D itu ditambah elemen seperti chip sedangkan non D tidak ada.
Jadi lensa type non D itu hanya bisa menghasilkan Multi-sensor Balanced Fill-flash alias tanpa 3 D.

Apa gunanya D itu...baca lagi ini...

:-?.....

Suryo : kamera kamu kan Canon kok nanyanya lensa Nikon? :-?

Mas Wok ... Lensa G sudah pasti seri D, kalo ndak ada D-nya, berarti bukan seri D.

to Kak D.Setiadi: Suryo punya F501 :D plus 20mmnya ...

---

to Suryo: yang jelas Sur.., non-D dibuat sebelum seri D keluar, trus type-D lebih mahal dari non-D ...
tapi aku punyanya yg non-D soalnya yg type D (selain mahal), jg bukan made in Japan, so kualitas lensanya kurang bisa dijaga.. quality controlnya kali )

Eh mau beli AF 50mm/1.4? udah baca reviewnya? mendingan cari 50mm/1.8 tapi made in Japan, kualitas optik jauh lebih bagus dan harganya jauh lebih murah (kata temenku yg punya lho..:D)

Suryo, lensa Nikon tanpa embel-embel "D" berarti bukan lensa D-type.

Lensa D-type pertama kali dirilis barengan sama Nikon F90. Waktu itu, Nikon F90 merupakan produk pertama Nikon yang dilengkapi sistem pengukur cahaya 3D Matrix Metering (bukan hanya sekedar matrix 2 dimensi). Dalam pengukuran cahaya 3D ini, diibaratkan kamera mengukur cahaya ruang berbentuk seperti kubus atau kotak 6 sisi. Jadi, karena ada dimensi jarak, dibutuhkanlah lensa yang bisa membantu pengukur cahaya di kamera mengukur jarak kamera ke obyek. Fungsi itulah yang dijalankan lensa D-type.
