Just one year after the release of the Sony DSC-RX100 III the next version was announced this month: Sony DCS-RX100 IV. As the body and the lenses are the same, I asked myself if it is worth to buy the new IV or get a decently prices III in August 2015.
Sony’s press release, some first reviews at the new camera and dpreview, a side-by-side feature comparison and picture quality comparison are already out. The difference in image quality is probably not there. I would like to add a complete list of differences in the following tables based on the specification RX100 III and RX100 IV at Sony. The first part of the table depicts major advantages of the IV vs III:

The heavy price tag of additional € 470 is worth if you are
- using video: the 4k video and slow motion of 40x is something special in the market and especially for a camera of this small size and weight;
- high speed shutters: the 32’000 is an incredible shutter speed allowing 1.8 aperture at bright light if you want to control depth of field or to get high speed sharp
images.
The better viewfinder, hopefully faster and more accurate autofocus, and the hopefully better performance at higher ISO, longer automatic expose times probably do not justify the price difference. Anyway, I will spend the extra money as I have finally found my
“point-and-shoot” camera.
Still, there are a few things that I will miss with the RX100 IV:
- GPS function build in the camera, optionally available to turn & off for each shoot
- USB 3.0 support
- Better protection of the Zeiss lens, while it is closed
Even Sony figured out that additional items can be sold with such a small camera. Picking the right accessors is the next part of the hobby. Sony has a nice web page for this:
- Additional battery NP-BX1 or the ACC-TRDCX charging Kit
- Memory card, fast, and big 😉 64GByte 280 MB/s e.g. SanDisk
- Maybe, the extra grip AG-R2
- Camera bag like LCS-RXG
Update: There is a comparison also done now by dpreview here.
Do you have some more insights on this? Any experience yet? Just share it…
Incredible this is a helpful web page.
