Jangkauan Penuh, Bobot Setengahnya
Panjang fokus yang sangat besar, desain yang ringkas dan ringan. NIKKOR Z 800mm f/6.3 VR S , dari Nikon , adalah lensa prime super-telefoto yang dibedakan oleh kombinasi unik dari salah satu panjang fokus terpanjang yang tersedia dalam paket yang sangat portabel. Desain yang berbeda ini dimungkinkan berkat penyertaan elemen Phase Fresnel, yang mengurangi berat keseluruhan hingga 50% dan panjangnya hingga 16% dibandingkan dengan lensa F-mount 800mm f/5.6 sebelumnya.
Desain Ringkas dan Ringan
Perpaduan teknologi yang canggih menjadikan lensa super-telefoto ini relatif ramping, membuka kemungkinan baru untuk panjang fokus yang sebelumnya hanya dapat digunakan dengan tripod/monopod.
- Elemen Phase Fresnel tidak hanya mengkompensasi aberasi kromatik dan pinggiran warna, tetapi juga menggantikan beberapa elemen kaca konvensional untuk menghasilkan tata letak optik yang lebih ringkas dan ringan.
- Bukaan maksimum f/6.3 yang sederhana menciptakan keseimbangan antara desain yang praktis dan terang dengan konstruksi yang ringan.
- Dibandingkan dengan lensa F-mount 800mm f/5.6 sebelumnya yang beratnya lebih dari 10 lb, lensa Z-mount 800mm f/6.3 yang baru ini beratnya hanya setengahnya, yaitu 5,25 lb. Selain itu, desain khusus untuk kamera mirrorless juga berkontribusi pada panjang lensa keseluruhan yang lebih pendek, yaitu hanya sedikit di atas 15 inci, dibandingkan dengan lensa sebelumnya yang berukuran 18 inci.
Optik S-Line
- Lensa ini membantu menghilangkan aberasi kromatik, pinggiran warna, dan aberasi komatik secara virtual, serta memiliki tiga elemen kaca ED (dispersi sangat rendah), bersama dengan satu elemen SR (refraktif panjang gelombang pendek).
- Elemen SR memiliki desain dispersi tinggi khusus yang membiaskan panjang gelombang yang lebih pendek dari biru; ini membantu mencapai rendering warna yang benar-benar akurat dan juga membantu membuat desain lensa lebih ringkas.
- Lapisan Nano Crystal Coat telah diaplikasikan untuk perlindungan anti-silau menyeluruh dari semua sudut, membantu menekan bayangan, pantulan, dan silau untuk kontras yang lebih tinggi dan respons warna yang lebih akurat saat bekerja dalam pencahayaan yang kuat dan kondisi cahaya latar.
Fokus Otomatis dan Pengurangan Getaran
- Sistem multifokus menggabungkan dua unit penggerak AF terpisah yang disinkronkan untuk menghasilkan autofokus yang sangat cepat dan akurat. Sistem ini menggunakan motor stepper yang menawarkan kinerja AF yang sangat halus dan senyap, sangat cocok untuk aplikasi foto maupun video.
- Pengaturan fokus manual penuh waktu juga dimungkinkan dan digunakan desain fokus internal, di mana hanya kelompok lensa internal yang digerakkan selama pemfokusan, untuk mempertahankan panjang keseluruhan lensa selama penggunaan dan untuk meningkatkan kecepatan pemfokusan.
- Stabilisasi gambar Vibration Reduction mengurangi guncangan kamera hingga sekitar 5 stop untuk memungkinkan pengambilan gambar dengan tangan dalam kondisi cahaya rendah.
- Synchro VR juga didukung saat dipasangkan dengan kamera yang kompatibel yang memiliki fitur sensor-shift VR, yang menggabungkan VR dalam bodi dengan VR optik untuk hasil yang lebih baik hingga kompensasi 5,5 stop.
Penanganan dan Konstruksi Profesional
- Desain fisiknya memfokuskan pusat gravitasi di sekitar dudukan tripod bawaan untuk pergerakan panning yang lebih halus dan responsif, terutama saat bekerja di atas tripod atau monopod. Dudukan tripod bawaan juga dapat diputar untuk memudahkan peralihan antara orientasi pengambilan gambar vertikal dan horizontal.
- Kompatibel dengan Z-Teleconverter TC-1.4x dan TC-2x opsional untuk memperluas jangkauan lensa ini lebih jauh.
- Tata letak kontrol "tanpa melihat" yang intuitif menempatkan semua tombol dan kenop yang sering digunakan di lokasi yang mudah dijangkau untuk mencegah perlunya mengalihkan pandangan dari jendela bidik.
- Penyegelan tahan cuaca tingkat lanjut mencakup gasket karet untuk mencegah masuknya debu dan kelembapan, bodi lensa terbuat dari paduan magnesium yang tahan lama dan ringan, serta elemen yang terpapar memiliki lapisan fluorin yang menolak kotoran dan minyak serta lebih mudah dibersihkan.
- Simpan posisi fokus menggunakan tombol Memory Set sehingga Anda dapat langsung kembali ke posisi ini dengan memutar cincin Fn—sempurna untuk menangkap gerakan yang cepat.
- Dua tombol L-Fn yang dapat disesuaikan dapat diatur untuk mengkonfigurasi pelacakan subjek, penguncian AF, pemutaran gambar, atau mode lainnya. Tombol L-Fn2 juga dapat diakses dari empat lokasi berbeda pada bodi lensa untuk memudahkan jangkauan.
- Saklar pembatas fokus dapat membatasi rentang fokus hingga 32,8' sampai tak terhingga atau dari rentang fokus penuh 16,4' sampai tak terhingga.
- Cincin Kontrol Terprogram juga dapat digunakan untuk mengontrol apertur, ISO, atau kompensasi eksposur.
- Dudukan pengunci Kensington untuk mengamankan lensa pada tempatnya selama sesi pemotretan jarak jauh.
- Menggunakan filter 46mm yang dapat dipasang langsung melalui dudukan filter yang disertakan.

This book may be life-changing!
Format: Paperback
This book gives an explanation of Bowen's family system theory. The first half of the book is heavy on the theory, and then the second half gets into a little bit of how to use it in real life. It doesn't read like a self-help book, and Gilbert gets props for not using words like "codependence" and other jingoistic psychobabbly words. She's completely blunt and realistic, and it's all well-written.
The basic theory is this: in order to have good relationships, you have to be a well-differentiated, individual self. This means that you have solid boundaries, and you can relate to other people without "lending and borrowing" the self, as Gilbert says. Or in my view, you can be friends with people without trying to become them or making them become you. Ironically, in order to work on being a differentiated self you have to do the work through your relationships. None of us are perfectly differentiated, so we can all improve our basic selves and our relationships. The less differentiated we are, the more anxiety in our relationships (because we get all tense about them), and the more they take on the following five postures, which can relieve anxiety in the short term but only mess things up more over time: conflict, distancing, triangling, under/over-functioning, and cut-off.
Probably the most important aspect of this theory is that undifferentiation and relationship postures are carried on from generation to generation. So it's not really your parents fault, but yes you learned it all from them, and they learned it from their parents, etc etc. Also your own level of differentiation and the postures you adopt in relationships are based on how you interacted with your entire family of origin, not just your parents. Gilbert stresses that in order to move up the scale of differentiation and have better relationships, we have to go back to our original families and work on our relationships there. This doesn't involve changing anyone else or acting like a therapist- all it involves is changing ourselves, and the way we relate to everyone else.
There is a lot more, I'm only scratching the surface here.
I am so glad I found this book, because it is convincing and explains everything clearly. I am motivated to try to work on myself, and I have some idea of how to proceed. Other books I've read on the subject were too barfy and jargony, or they touched on the surface of the issues without getting to the heart of the matter.

Superb!
Format: Paperback
This was my first read on Bowen Family Systems. I was pleasantly surprised at the value and relevance of the ideas. For example, that all intimate relationships produce some anxiety in the partners! We cope with that anxiety using behaviors which may cause excessive 'distancing' from our loved one.(Something of a push-pull going on here). Another simple idea is that keeping some type, any type, of connection (ie. avoiding a 'cut off') with members of our family of origin (brother, sister, parent, child) is vital to having good relationships with our chosen loved ones. I don't recall ever hearing that idea before. Unlike many psychological revelations, this one is fairly simple to assess in our own lives - just look at your family of origin and see what kind of relationships you have! Gilbert is realistic that big changes in ourselves are not likely, but even incremental small steps forward can have profound impact on our relationships. Gilbert is a very good writer, with occasional (rare?) understated humor, which makes the material easy to access for anyone interested enough to try. Highly recommended.

Loaded with Information
Format: Paperback
Roberta Gilbert's overview of Murray Bowen's Family Systems Theory is a thorough introduction on how we build individuality through constant interaction. Although it takes a few chapters to understand the terminology ("anxiety", "differentiation", etc.), Gilbert pieces together the general concepts of Bowen's theory through analytical study and real world interpretation. The idea of triangulating and the importance of original family relationships stand out to me as the overwhelmingly important activities which many people don't think twice about. This isn't to discount other aspects of relationships- such as Overfunctioning/underfunctioning, conflict, distance, and cutoff- but these certainly stand out due to the attention Gilbert gives to them.
The one point that I disagree with (although Bowen would say I am in denial) is the urge to put yourself on a different emotional in any and all connections. I understand the benefits to this, but the idea that I would detach and remain coolly above all interactions between those closest to me strikes me as depressing. I feel differentiation and togetherness (which he calls "fusion") do not have to be mutually exclusive. This critique is grounded in pure opinion. My critique from an analytical perspective centers on her ignorance, which could even be called contempt, of love in a relationship. Her rudimentary overview of love in relationships places it neatly in a box next to cutoff, triangulating, and other day-to-day activities. I don't see myself as a hopeless romantic, but the unique attributes of love is noted near unanimously. Viktor Frankl, a noted psychologist himself, wrote about it in his excellent book "Man's Search for Meaning".
Nevertheless, I recommend Extraordinary Relationships for those who really want to dig into ways of improving themselves and the relationships around them. Although the concepts might be a little narrow, the general Bowen Family Theory idea should not be ignored.
