Im sure the family wedding will cost more than £450.

! " Best HD camcorder for £450 family wedding"

!il just edit the title....

I agree with all the above
There is no Best
Full HD 1920x 1080 does seem to be the standard now however the mere provisin of these pixels say not much about perceived definition
A lot of that is down to hardware and firmware/ software processing.. Canon, Sony Panasonic all make decent models
In short
Your budget, preference for SD card or HDD drive and perhaps current or recent model determine what you get
As for "wedding use" the only caveat is that indoor situations where lighting is never quite optimal challenge all camcorders and most consumer models will need to be used with these limitations in mind
I have used the HG10 and quite like like but think the HF100 is better
You might want to suggest other models for comment
