1st flight results with the full frame mirror-less camera have been a joy, the image quality surpasses anything I have achieved this far. Cropping down to detail works a treat and the sharpness, even at wide apertures is gratifying.
Problem is, it’s filling the SD card at 30Gb an hour as an autoKAP mule making processing a tiresome chore: an hour in the sky equates to about a day sifting; so many beautiful shots of featureless mud or unlit treetops fill my hard-discs now!
With such a hefty image file size (25mb a shot) a selective, directed camera approach is required, if only to speed the sort and save. For me a directed camera means video relay. The RX1 is supplied with an HDMI output so how hard can it be? An HDMI/AV converter is available (variously sold under the brand ‘Silverlight’) and I got mine from HobbyKing. It’s known to be compatible with the Sony Nex series video format so I was hopeful it would work with the Cybershot too.
…good news is: it works and no additional power is required. It weighs less than a mini cam…bad news is: it sticks out the side of the camera like a low tree branch on a bus route, it has ‘break me’ written all over it…still provided I’m careful getting the camera on and off the rig it should be OK, at least until I can investigate a less temporary fit (a cut down adaptor and heat-shrink protection spring to mind) later…
Fitting all I need for directed camera work into a box is important for kit survival and field procedure- a place for everything :
All up the RX1 rig is a compact 980g payload, it includes a GPS OSD module for CAA compliance which is not strictly required and removing it would bring the weight down by about 50g. As the rig is wired up with a UBEC loom powering an Immersion RC 5.8GHz video transmitter and Spektrum 2.4GHz receiver I’m reluctant to pull it all apart to get the weight down before I have got my eye in with the new weight and viewfinder set up. I recall from the early outings with the Leica X1 it takes a while to learn what 60m AGL looks and feels like.
The battery runtime on the rig should benefit from the reduced power draw compared to the previous minicam set-up with the RX1 battery powering the video out.
Tweaking the power supply to reduce weight and ruggedising the HDMI hardware are the next priorities…after getting some air time in!
