Not long ago Rode announced a new VideoMic Pro and now it's available. Didn't I just grab a new Microphone Windscreen over my VideoMic? This does not appear to be a replacement for the already popular VideoMic, but a new microphone altogether. Smaller form factor, better shock mounting, external switches, and a new +20db setting. Price obviously is more than the non-Pro VideoMic, but the new shock mount and smaller form factor already has me sold. Unlike the large VideoMic, this new VideoMic 'Pro' won't look as awkward when mounting on the smaller GH2 camera.

If you've been hiding under a rock, you might have missed all the ads for Varizoom's Crossfire stabilizer. Seems like they are really pushing this product towards DSLR shooters. It's a hand held video stabilizer that combines a tripod as the lower weight. When you're not running around, you've got a tripod ready to go. This is another product similar to their stabilizer/monopod a.k.a 'FlowPod'. How well does it work? I don't know, but it's set at a price where i'm not willing to find out. So unless you really need a set of sticks under your stabilizer, you can find it here: http://www.bhphotovideo.com/c/product/750674-REG/VariZoom_VZ_CROSSFIRE_CrossFire_FP_Stabilizer.html
