Some slashCAM readers are still waiting for the availability of the Kinefinity Terra 5K, but there is still no fixed delivery date. But even without a Global Shutter camera, there is movement in the product range of the Chinese CineCamera producer. Without much announcement, a Terra 4K appeared on the website of the European distributor HD-Videoshop, which we could then also find on the international pages of the manufacturer.
The new model is a conventional Terra housing with a new 4K sensor, which means that Terra accessories for the 5K and 6K models can also be used without restriction with the Terra 4K.
The new Kinefinity Terra 4K
Kinefinity itself speaks of a 4K sub-S35mm format CMOS sensor with a crop factor of 1.85 (compared to FullFrame). Upon request, HD-Videoshop confirmed that they are actually installing a new sensor and not an S35-sensor which is only limited by firmware. If it is a horizontal Crop-Factor, the sensor would be about 19,46mm wide. If it is a diagonal indication (which we would rather assume at this point), we would have to deal with a sensor in the order of MicroFourThirds. Exact size specifications of Kinefinity are not yet available.
Kinefinity says that the noise level is halved compared to the Terra 6K and the base ISO is 1600. Depending on the resolution, 13 or 15 f-stops should be possible. (The Terra 6K is specified with 16/14 f-stops). The 15 f-stops are only reached in a Golden 2K sampling mode and, as with the 6K, the resolution is limited by that.
The Rolling Shutter should work much faster than with Terra 6K (which was one of our main criticisms in our test.
The Terra 4K will be available from 3,599 Euro starting in November. However, this is only the body without VAT. In a minimum ready to shoot bundle (including battery, monitor and SSD) the Terra 4K costs then incl. VAT still more than 5,200 Euro.
Compared to a similarly priced Blackmagic URSA 4.6K Mini, the Terra 4K has the advantage of compact dimensions and low weight (>1 kg), which should make it interesting for gimbal applications. In addition, there are unique slow-motion possibilities with up to 100fps in 4K wide (4096x1716) and a remarkable color science.
