Sony RX100 IV & Sony RX10 II | Sony Updates The Best Compact Camera & Superzoom

By Kishore Sawh on June 10th 2015


It’s almost unfortunate that Sony unveiled the a7RII today, and not tomorrow because it overshadowed two other Sony releases which are, in many senses, just as exciting and may even appeal to more people. Along with the a7RII, Sony announced refreshed variants of the superzoom RX10 and their famous RX100.

To many, myself included, the RX100 is the best truly pocketable camera on the market. When Sony announced it, many balked at its price, only to realize the value was there. Then when they added the shorter but faster lens and an in-body EFV to the MK3, we just had to sort of stand there and shake our heads in wonder at how they managed to create such a thing. Well, they’ve taken it a step further and made it even better, and for those like me who have had and loved the RX100 since version one, this update will probably get me back to the cash register.


The New RX100 MKIV retains the same 1 inch 20MP CMOS sensor, but with a DRAM chip, and paired with the MK3’s 24-70 f/1.8-2.8 lens, but that’s about where the similarities stop. There is a new and better OLED viewfinder, new electronic shutter technology, and vastly superior video capabilities. The AF system has been upgraded but still uses contrast detection.

The electronic shutter is a huge boon in my opinion which sees the shutter speed max rise from 1/2000 to 1/32,000 of a second. That’s a lot like what Fuji has done with their newer cameras. The RX100 MKIV can now shoot 16fps in still mode which is astonishing.

The new “stacked Exmor RS CMOS’ chip with new processor and RAM also allows for 4K video shooting and crazy slow motion video. At XGA resolution (1280 x 800), it can shoot 960fps, which is about 40x slower than normal. In 720p HD, it can shoot at a whopping 480fps and at 1080p full HD, it still can do 240fps.


The RX10 superzoom sees much of the same upgrades to come to the RX100 compact, such as the same sensor and RAM combination leading to similar upgraded shooting abilities. It has an XGA OLED viewfinder, water and dust resistance, still has the 24-200 f/2.8 lens (a beauty), does 14fps, and now has the same 4K and slow motion video as the RX100.

Both models have built-in WiFi and NFC connectivity and should be available for preorder on June 17th. The RX100 is expected to come in around $1000, and the RX10 around $1300. These are not cheap cameras and really are not for everyone at those price points, but it’s hard to argue with what they offer.

    The Hi speed video on the RX10-II its not Full HD or full pixel readout, its pixel shifted so you will see a lot of liaising on the videos :(

    Guess this pretty much is the year of 4K. Panasonic’s been putting 4K in everything lately, and looks like Sony’s risen to match that as well. And getting a 4K capable sensor pretty much means you get great high frame rates at lower resolutions, though I think Sony’s got the lead here now. While I’m sure these are still great photo shooters, the video improvements are off the hook. I have used little cameras as extra video shooters in the past, and while it’s not the point of owning the camera for me, it’s a feature I want when I need it.

    The new cameras sounds great! When is the A6100-A7100 who knows model name. E-mount camera coming.

    Have had my RX100 for a couple years now – and it continues to take great shots despite being thoroughly abused, frequently not in it’s case and exposed to the elements on my dirtbike.

    I had just about managed to convince myself I didn’t need the MKIII… but this MKIV is going to make me poor!

      I convinced myself that the mk2 was the one I wanted since it has a hotshoe :)

      I agree. I still have the RX100 mk1 and it is perfect.
      I don’t own a cover of any kind and have “abused” it over the years. It has fallen down too many times to count that the metal casing has bent in many of the corners, but it is still going strong.
      I am (secretly) waiting for it to fail so I can buy a new one :)

    I am looking for a small capable camera that is easy to carry around. This just made my decision a little harder… or easier depending on what I decide. :)

    That 100 looks like a sweet little camera.

    I look forward to purchasing an RX100 iv in 2 years. I bought a refurbished mk2 for $380 (with sd card and leather case) a few months ago and it’s been my goto travel and everyday use camera. I’ve even used it on assignments and my clients will never know.

    Sony is truly innovating in ways that Canon and Nikon never will and it’s a little discouraging as a heavily invested canon user.

    They could go to hell.

    Wait a few months for the price to come down and the rx100 mkIV will be almost the perfect compact.

    The RX100 is still a I-want-thing…
