Photography Kits by the Smartphones - A New Level to Mobile Photography


I can't recall the date, but in 2023 Xiaomi first unveiled the photography kit for its Xiaomi 13 Ultra in China. (Ok now checked it was 18th April, 2023). This original release marked the first time a smartphone manufacturer offered a dedicated, branded eco-system package to transform a phone into a traditional camera body.

That first first-party Photography Kit introduced - Camera inspired Grip with Bluetooth connectivity to the smartphone, 67mm Filter Adapter Ring, Premium Nano-skin Case, Custom metal Lens Cap and Lanyard - and thus laid the groundwork for future photography kit for the smartphones. 

The evolution of Xiaomi’s first-party photography kits shows a clear shift from basic wireless controls to zero-latency, high-power modular systems.

চুঁচুড়ার ঘণ্টাঘাট এবং ঘণ্টা গির্জার গল্প

আগেই বলেছি যে কলকাতা থেকে 25-50 কিলোমিটার দূরত্বে হুগলী নদীর ধার ঘেঁষে গড়ে উঠেছিল একাধিক ইউরোপীয় বাণিজ্যকেন্দ্র তথা উপনিবেশ - বারাকপুরে ব্রিটিশরা, উল্টোদিকে শ্রীরামপুরে ড্যানিশরা, তার উত্তরে চন্দননগরে ফরাসীরা, চুঁচুড়াতে ডাচ বা ওলন্দাজরা, এবং ব্যাণ্ডেলে পর্তুগীজরা। 

আজকের গল্প চুঁচুড়া ফেরিঘাটের একটু উত্তরে ঘণ্টাঘাট নিয়ে। এই ঘাটে কি ঘণ্টা ছিল? কোথায় গেল সেই ঘণ্টা?
