I’ve spend a couple of days putting a PMW-320 through it’s paces. The 320 is the latest addition to the XDCAM EX line up. It’s very much like the PMW-350 which I reviewed in depth last year, the principle difference is the sensor size. The PMW-350 is 2/3? while the PMW-320 is 1/2?. The camera can be purchased with or without a lens, the supplied lens is a Fujinon 16×5.8mm HD lens that has both autofocus and manual focus. The lens mount is Sony’s standard 1/2? hot shoe bayonet, so owners of DSR300? or PDW-350?s etc can use  their lenses directly on the PMW-320. As with the 350 the lens that comes with the 320 is pretty good. Nice and sharp and with a good feel to it considering the cost. It does however suffer from flare under harsh lighting and this can soften the picture a little. A good lens shade or matte box with flags would really help this lens.

Externally the 320 and 350 are almost identical. The give aways are the rubber strip under the handle, EXMOR badge on the side and lens mount ring are dark blue on the 320, black on the 350. Off the shelf the stock PMW-320 actually has more features than the 350. SD is included as standard and it can output to both HDSDi and HDMI at the same time. Buttons and switches are the same on both camera as is the excellent high resolution colour viewfinder. On switching on and looking through the menus they appear to be the same as the 350, no there surprise really, so just like the 350 instead of the picture profiles and Cinegammas found on the EX1R and EX3 we have Scene Files and Hypergammas more like a PDW-700 or other high end Sony cameras. Talking of the EX1R and EX3, there has been a little confusion over the sensors used in the 320. At first I got the impression that the 320 used new sensors, but I was told at NAB that was not the case and the 320 has the same sensors as the EX1R/EX3. So I was somewhat surprised when I started looking at the images from the 320 to see less noise and a different looking picture.

On the PMW-320 there is a wider range of camera adjustments compared to an EX1R. For example as well as detail settings there is also a section for adjusting the Aperture correction which can also sharpen and soften the look of the camera by boosting high frequencies. Out of the box I didn’t think the 320 was quite as sharp as my EX3. But after a few minutes on the bench and with a few tweaks to the detail and aperture settings the camera was looking very good indeed (detail -8, aperture +20). While not a quiet as the PMW-350 the 320 does appear to have less noise than an EX1 or EX3. It’s not a big difference, but every little helps. My guess there is additional signal processing going on to reduce the noise.

The use of scene files for the PMW-320 and Picture Profiles on the EX1 does make it harder to match the cameras if your using non-standard settings. It can be done, but it takes a little more work.

The power consumption of the 320 is, once again remarkably low. I was powering it with a 95Wh battery and it lasted most of the day. There are no fans to make noise and it’s very light yet well balanced. The big question on my mind when I heard about it was, why buy a 320 when you can get an EX3 for a lot less or a PMW-350 which has amazing image quality for another £2k to £3k. Well obviously the form factor is very different from an EX3. The 320 is a full shoulder mount camera, complete with slot for a radio mic that runs on V-Lock batteries. The EX3 is a semi-shoulder handy-cam running on small batteries. Both will take 1/2? interchangeable lenses, so no great difference there. But as well as the form factor, which can be very important, the PMW-320 also adds SD recording and HDMI output. There is also the small improvement in image quality to consider. I like the 320, not as much as I like the PMW-350, but it is a fair bit cheaper so could prove to be very attractive for those on a tight budget that want the shoulder mount form factor as well as those that may already have nice 1/2? lenses on their PDW-350?s or 355?s.
