If Sony is looking for a heavyweight contender in the battle for semi-pro camcorder supremacy then the EX1 might well be it.

Well, it would be if the battle could be won at the weigh-in. You see the first thing we noticed when removing this new cam from the box was its weight. At 2.8kg it is a bit of a back-breaker but further investigation revealed some nifty innovations that go some way to compensate.

Sony's heavyweight camcorder

The EX1 is slightly larger and 400 grams heavier than its forbearer, the Sony Z1 HDV cam. One giant difference between the Z1 and EX1 is that the latter has no tape mechanism. The video is recorded on to Sony’s brand-new solid-state format, the SxS memory card.  

The EX1 captures video images via three 1/2-inch CMOS sensors and processes this information into a variety of video formats but they are all HD. If you require standard- definition video then all you have to do is down convert when you play out from the camera to your capture device.

Well designed cam

Our first impressions of the cam were positive. It looks and feels well built and the hefty Fujinon HD lens is a massive improvement on the Z1’s inferior lens.

Sony has retained the excellent lens hood with built-in barn door shutters but the new lens has a manual focus ring with end-stops so you know when you have reached infinity or minimum focus.

Without end-stops focusing has always been a very vague procedure as the focus ring will keep turning indefinitely. The addition of stops helps distinguish pro-kit from consumer camcorders.

The lens also has a proper iris ring which is a fantastic improvement on the Z1. We found setting both exposure and focus was precise, fast and comfortable unlike most other cameras in the semi-pro range.

New lens design

With practise we were able to adjust the focus and iris and maintain constant support under the camera with only one hand. The ability to keep the camera steady while adjusting the lens is crucial for recording wobble free and level footage.

The camera has a 14x optical zoom and the lens is initially quite a bit wider than the Z1 but zooms to the same focal length at the telephoto end. This wider lens is an advantage in many situations such as filming handheld or in confined spaces like car interiors.

The weight of the PMW-EX1 is frequently an issue. Bear in mind that the main support point is the zoom demand grip so your right wrist will need to carry most of the weight.

The new lens design means that your left hand can help and still make adjustments but its near-3kg will soon put a considerable strain on your right wrist and make handheld coverage very uncomfortable.

Easy to control

This would be a disaster if not for Sony’s new innovation of an adjustable zoom demand grip. The angle of the grip can be adjusted by 90 degrees and this feature allowed us to operate the camera at chest height.  

We were still using the eyepiece but with the zoom grip set at 45 degrees most of the weight was transferred to the palm of the left hand without sacrificing any zoom control.

This is good as you don’t want to be shooting from hip level and up your subject’s nose which is often what happens during the filming of observational documentaries.  It will also stop you from filming via the flip-out LCD screen which is never a good idea as you lose a point of contact with the camera making it less stable.

Therefore it is essential to be able to hold the camera easily at about your subject’s eye level and the adjustable grip allows you to do this.

Fun filming effects

When it comes to actual filming, we found many of the usual features you would expect such as two levels of neutral density (ND) for shooting in bright  conditions, three levels of gain, white balance presets and two memory settings, A and B.

Position B can also be assigned as auto-white which is a boon. The shutter speeds range from 1/16th to 1/2000th of a second and the EX1 also has a panic button which gives you full auto.

Some other features available include selectable gamma curves, a Slow and Quick Motion feature, and a histogram function for assessing video levels.

During filming we were able to control the most commonly required functions with a switch rather than via a menu, which really sped up camera operation.

An impressive viewfinder

The EX1 has an excellent eyepiece viewfinder with accurate colours and a noise free, high- resolution picture. Assessing exposure is easy but we found that the camera has such a massive depth of field that, when wide, the image never seems to go out of focus.
