Google has an alert service. If you put in a search term it will send you a daily summary of alerts to the subject. A few days ago, I put in "HDR-GW77". Today there was a single alert with a link to "Sony HDR GW77 Garden Video in HD using Tele Macro Mode on ...Use of telemacro mode, which enables close-up distances of as little as 80cm at 300mm focal ...vimeo.com/45606199
". I followed it and saw your video. It was the same one you started the thread with. Sometimes google can make the world seem small.
So it appears the HX9V ( that got such goodreviews as a video camera) is better for video than the RX100. I think I was expecting at least an equal for video. The RX100 suddenly showed up as available to buy at the Sony Store online, so maybe a few will soon get them and post some real results. If what the manual says is as bad as it sounds, I am a lot less interested in the camera. Not being good at video would hurt my feelings.
I am familiar with the aggravation of button noise. The HX9V that I have is actually the third one. The first one had a flash that didn't pop up so Best Buy gave me a new one. I took that on a trip. I was used to the video button on my Panasonic that is easy to push. The video button on HX9V is recessed a little and slower to respond. My thumb is one of the bigger ones issued. Because of the slower response and thumb, I was squeezing hard to get it started. After a week, part of the plastic developed a squeak. It was not noticeable at the beginning of a clip, but every clip from the second half of the trip ended in a squeak. Best Buy was harder to convince, but they replaced that one too. To solve the problem, I cut a piece of plastic with a hole punch that matched the size of the button and carefully glued it on so it is no longer recessed. And, I am more gentle now.
If the picture quality of the video is good, I might be able to live with the restrictions. Usually my zooming and panning shots are less interesting that if I hold still and usually I'll pick the best part out of the middle of the clip in editing. Button noise would be eliminated in the process.
I agree it seems stupid to allow those flaws. Maybe if the reviews hit it hard it will improve in the next versions. The HX9V was improved from a few earlier models. The HX10V, stepped back in video quality. The HX20/30V seems to be OK so far. CNET was pushing it for awhile as this years good choice.
