Lensa Serba Bisa Sehari-hari
Dengan memadukan aperture cepat, ukuran kompak, dan rentang zoom serbaguna dari wide hingga telephoto pendek, Lensa Canon RF 28-70mm f/2.8 IS STM dapat menjadi lensa serbaguna sehari-hari untuk semua jenis pembuat konten. Rentang zoom 28-70mm dan aperture cepat f/2.8 membuat lensa ini sangat cocok untuk segala hal, mulai dari lanskap hingga potret dan segala sesuatu di antaranya. Lensa ini juga menawarkan optik berkualitas seri L sambil tetap mempertahankan bentuk yang lebih kecil—dan harga yang relatif terjangkau untuk kinerja dan fitur-fiturnya.
Cepat dan Kecil
Lensa RF 28-70mm berbeda dari lensa seri L lainnya (RF 24-70mm f/2.8 L) karena memiliki ukuran yang jauh lebih kecil dan ringan. Hal ini dicapai melalui desain optik yang canggih dan titik awal sudut lebar 28mm yang lebih konservatif, namun tetap sangat mumpuni. Saat tidak digunakan, lensa dapat dilipat ke dalam dirinya sendiri, sehingga menghemat ruang lebih banyak lagi di dalam tas atau saat disandangkan di bahu.
Optik Berkualitas Seri L
Canon telah menempatkan performa optik RF 28-70mm pada level yang sama dengan lensa seri L mereka yang terkenal. Ini bukanlah prestasi kecil, terutama untuk lensa yang juga berhasil mempertahankan ukuran yang relatif kecil. Desain optik canggih lensa ini membantu memastikan gambar detail dapat ditangkap di seluruh rentang zoom dan bahkan saat memotret dengan bukaan lebar.
- Dua elemen Ultra-low Dispersion (UD) terletak di bagian depan desain lensa, sebuah konfigurasi yang sebelumnya hanya ditemukan pada lensa seri L, yang mengoreksi aberasi kromatik dan mengurangi bobot kelompok lensa depan.
- Dua elemen asferis cetakan kaca menekan aberasi dan membantu menjaga ukuran lensa keseluruhan tetap kompak.
- Lapisan Super Spectra Coating (SSC) mengurangi silau dan bayangan akibat cahaya latar untuk mempertahankan transmisi cahaya dan kontras tinggi dalam kondisi pencahayaan yang kuat.
Autofokus Cepat dan Stabilisasi Terintegrasi
Manfaatkan sepenuhnya optik berkualitas tinggi lensa Anda dengan menggunakan sistem autofokus stepper cepat (STM) dan Penstabil Gambar Optik pada RF 28-70mm untuk memastikan gambar yang sangat tajam. Kedua fitur ini akan membantu mengunci subjek Anda dan memastikan guncangan kamera terkontrol.
- Motor autofokus Stepper (STM) cepat dan senyap untuk pengoperasian optimal selama pengambilan gambar diam maupun video.
- Pengaturan fokus pernapasan terkontrol dengan baik, menghasilkan fokus yang mulus selama perekaman video.
- Penstabil Gambar Optik ini memiliki kemampuan hingga 5,5 stop secara mandiri atau hingga 7,5 stop bila digunakan bersamaan dengan sistem stabilisasi bawaan kamera yang kompatibel. Sistem ini akan membantu mengurangi keburaman akibat guncangan kamera saat memotret tanpa tripod, bahkan dalam kondisi pemotretan gelap dan dengan kecepatan rana yang lebih lambat.
Desain Ringan dan Ringkas
Kunci keberhasilan RF 28-70mm terletak pada konstruksi fisiknya. Lensa ini kecil, ringan, dan tahan lama. Konstruksi tahan cuaca, seperti kaca seri L, membantu memastikan lensa ini dapat digunakan dalam kondisi hujan atau panas terik. Hal ini menjadikannya pilihan yang andal bagi fotografer dan videografer.
- Desain yang dapat dilipat membuat ukuran lensa menjadi lebih ringkas saat tidak digunakan.
- Cincin kontrol yang dapat disesuaikan dan cincin fokus manual yang halus memungkinkan pengoperasian lensa secara taktil.
- Konstruksi kedap cuaca memungkinkan pengoperasian dalam kondisi cuaca yang kurang ideal.

GOOD AUDIO
Capacity: 16gb | 416gb Storage, Color: Pink
i use this as a backup second machine for travel so the low resolution is not a problem.
the performance is as expected, while the quality of the audio (voice) is better than expected.

BE AWARE AND NEVER BUY THIS LAPTOP!
Capacity: 16gb | 416gb Storage, Color: Silver
I purchased this laptop in January, and by March, it was already showing major issues. The performance declined rapidly — it became unbearably slow, frequently crashed, and often struggled to open even basic programs or web pages. Using it has been incredibly frustrating.
Unfortunately, I didn’t dig deep enough into reviews before buying and was misled by overly positive ones. After running into these problems, I did more research and discovered that this model is widely known for poor performance and reliability.
I called HP and they told me that Amazon or 3rd party sellers modify the laptop from the original 4 GB RAM to 16 GB. This laptop is not compatible with 16 GB, and that's why this is a piece of garbage.
HP also informed me that there are many customers who are experiencing the same problem, but because the laptop was modified by a third party, they can’t honor the warranty or provide technical support for the device in its current configuration.
I strongly recommend avoiding this laptop. Take the time to research alternatives (and maybe invest a bit more) to get something reliable. This one simply isn’t worth the frustration.

A Genuine Game-Changer for Manufacturing Management
Color: Matte Black, Clear Lenses, Size: Standard
A Genuine Game-Changer for Manufacturing Management
These glasses have been nothing short of life-altering for my career. As a production manager overseeing a manufacturing facility, documenting Standard Operating Procedures (SOPs) has always been a significant hurdle. My primary goal in purchasing these was to record high-quality POV video of processes, which I can then feed into AI tools to generate written SOPs. This isn’t just a win for my productivity; it’s a win for my crew, as it finally provides them with the clear documentation they need to succeed, relieving me of the stress that comes with inconsistent training materials.
**Design & Comfort**
I initially opted for the larger frame, but the height was a bit much aesthetically for my face. The standard size, however, is excellent. I have a history of headaches from standard eyewear after long days, but these remain comfortable for extended wear. They are impressively discreet—I had multiple people compliment them on day one without ever realizing they were smart glasses. They are convincing enough to pass as normal eyewear to the untrained eye.
**Performance & Battery**
* **Video & Audio:** The video quality is surprisingly clear, and the microphone performance is exceptional. I’ve taken several calls while wearing them, and the recipients couldn’t tell the difference between these and my phone’s handset. The audio is solid—provided you keep your expectations realistic regarding the low end. The bass is sufficient for daily listening.
* **Battery:** This is the one area that requires adjustment. You’ll get about 30+ minutes of continuous recording, which drains the battery quickly. However, the charging speed via the included case is remarkably fast, which helps mitigate the downtime.
**The "Unexpected" Features**
While I bought these for SOP documentation, the note-taking and translator features have been revelations. On the production floor, I’m constantly pulled in four different directions. When I need to track material requests or quick process changes on the fly, these allow me to capture information immediately so nothing slips through the cracks. It has turned a single-use tool into an all-day essential.
**Verdict**
I am currently investigating sourcing safety-rated lenses to integrate these into my daily shop-floor workflow. While the frames themselves aren't officially safety-rated, for office-based procedures and light floor work, they have already become a staple of my daily routine. Between the hands-free note-taking, clear communication, and the efficiency they bring to training, these are an incredible value for anyone in a management or technical role.
**Pros:**
* Excellent microphone and video clarity.
* Inconspicuous, stylish design.
* Invaluable for hands-free documentation and note-taking.
* Fast-charging case.
**Cons:**
* Battery life is limited during heavy recording sessions.
* Frame is not officially rated for high-impact industrial safety environments.
