eh you know rough quote of V1? hows the A1 ar? never use before... i've been using pd, dvx and z1... pd still the nicest... in terms of everything-light, build...
OK, lets' start with A1 first. To me, it is a very good camera to cover event, it is light and the video quality is remarkable, anyone who uses A1 will simply love it. One of my customer ever comment on the size, being small and look like a toy, but he is truely surprise when I show them my final work, it is not even in HDV, only in 720 X 576, standard PAL DVD Widescreen. Anyway I do not use this for HDV. You can get one for $3600 (Grey Set).
Why use A1 for wedding event??? In most of the wedding I cover, around 60~70% are HDB flats, they are tight in corners and still I have to give way to the photographer sometimes. With A1, you can record even with the limited space around you, especially during gate crashing. To me Sony A1 is just a fantastic system to use. I have experience the following camera: Canon XM2 & Sony VX1000, I dare to say, the image quality of A1 does not lose out in SD, I feel its even better.
V1 will be released with the official price of USD$4800, I hope to upgrade this by end of 2007. The reviews for this system is good, however I am still looking for options, because V1 uses a completely different series of batteries.
