Sony has just announced three new 4K HDR (3840×2160) palm-sized camcorders during IBC 2017 in Amsterdam: the XDCAM PXW-Z90, the NXCAM HXR-NX80 and the Handycam FDR-AX700 with an improved AF system.

The new camcorders have a Sony 1-inch stacked Exmor RS CMOS image sensor, and all three support an instant HDR (High Dynamic Range) workflow with HLG (Hybrid Log-Gamma). According to Sony, the most exciting thing about these new camcorders will be the fast Hybrid Autofocus system.

Sony FDR-AX700

The fast Hybrid AF system relies on 273 phase-detection AF points that cover approximately 84% of the shooting area, a high-density placement of autofocus points and a newly developed AF algorithm. Phase-detection AF frames make it easy to detect the focused area in order to monitor the subject that is in focus.

The new camcorders feature a high-resolution OLED viewfinder (0.39″ OLED, 2.359k dots) as well as a 3.5″ 1.555k dots LCD touch-screen display. It will be possible to quickly switch focus from one sbuject to another with adjustable AF drive speed, tracking depth range and subject switching sensitivity.

Sony HXR-NX80

According to Sony, the HLG HDR workflow speeds up post-production work and produces high-quality HDR content faster without grading.

Key features of the new Sony camcorders:

  • 4K (3840×2160) full-pixel readout without pixel binning (through an enhanced BIONZ X image processing engine)
  • Super slow motion recording – 1000fps in PAL and 960fps in NTSC. Sound will not be recorded in the super slow motion mode. Sony has not published the exact resolution for the super slow motion at such high rates, but if previous models are anything to go by, it will be below Full HD .
  • Slow and Quick motion recording – Full HD, maximum 100fps in PAL and 120fps in NTSC. Sound will not be recorded in Slow motion mode.
  • S-Log3/S-Gamut3 capabilities for further → continue…

GH5 Firmware Update 2.0

By cameraman

This week Panasonic announced an update to the increasingly popular GH5. While some of the other camera manufacturers appear to be holding back on providing innovative video functions in the DSLR form factor, Panasonic are clearly going for it… and it shows.

Big news for video shooters is the addition of an ALL-Intra recording mode. This gives us 4:2:2 10-bit ALL-Intra recording at 200Mbps in HD resolutions and 400 Mbps at UHD or 4K. You’ll need to use the new speed Class 90 SD cards to push it to the limits, but this seems a small price to pay for such potential quality.

There’s now a 4K HDR gamma curve compatible with BT.2100 which Panasonic are calling HLG (Hybrid Log Gamma). You can choose HLG in the Photo Style menu when you want to enter the world of high dynamic range. There’s also a low bit-rate 4K HEVC recording mode for playback on HEVC compatible monitors.

Also recorded in HEVC is the high resolution anamorphic mode which enables video recording using an effective pixel equivalent to 6K (18 megapixels) with a suitable 4:3 anamorphic lens. So for PAL areas we’ll have the option of 4992 x 3744 at 4:2:2 10-bit and 200 Mbps Long GOP.

When the GH5 was first launched, many people complained about the auto focus performance when shooting video. The good news is that it looks like Panasonic have listened and report improvements to auto focus tracking and performance in low contrast situations. We’re looking forward to testing this soon.

With a new handshake correction mode in the body I.S. (image stabiliser), many improvements to still photo modes and the usual bug fixes, this looks like being an important upgrade for GH5 owners. Panasonic say it’ll be available late September:

Until recently, I’ve been more than happy → continue…
