The just released Sony FDR-AX100 Handycam is not just a 4k recording multipurpose camera but it also hides a 720p 120f mode which so far seems to be lower quality than regular 720p video cameras. The quality while usable is not ideal. The resolution seems to be well below the stated 720p in slow motion mode.
There is a sister model with the same sensor called the HDR-CX900 which shares all features “Including 720p 120F recording” except the 4k recording and of course a discounted price. However the $500 shave might be unwarranted considering the 1.5k investment for the CX900 which for $500 more you get 4k on the AX100.
- 4k recording at 30p and 24p.
- 720p mode at 120 frames / sec.
- 1080p 60 frame mode.
- 12x Optical Zoom with Steady Shot
- WiFi and Remote Operation
- 20.9 Megapixel 1″ (13.2mm x 8.8mm) back-illuminated Exmor R® CMOS Sensor
- F2.8-F11.6 Lens Range from Wide to Tele.
According to recent early reviews the camera performs well in good light but has a rolling shutter that seems two generations behind. Even slow pans exhibit the skew. Slow motion seems to be a spec added for show and not quality.
