    پیش فرض

    تغييرات نسبت به نسل قبل زياد نبوده اما به نظر من مفيد بوده.
    به خصوص:
    تغيير پردازشگر
    بهبود لرزشگير داخلي
    افزوده شدن بلوتوث و بهبود وايرلس
    همچنين امكان استفاده از پاوربانك مناسب به عنوان باتري در زمان عكاسي

    اين هم ريويوي اوليه توسط DP

    شايد منطقي نباشه ولي من به شدت طرفدار اين كلاس دوربين ها هستم
    Captan تشکر می‌کند.
