said in advance - the HF G30 is the hammer!
Many are disturbed by the dimensions and the weight of the camcorder - so I think that's good, more weight is also more inertia and thus less camera shake. The HF G30 is very good in the hand - much better than the small camcorder.
Very good solution is the manual lens cover - automatic locks tend eventually to time catching and then it will be expensive.
The zoom is really great - from 50 meters can I read the menu from Italian razor sharp.
I learned a long time movies with a Canon HF 200 and have love the accessory shoe - no more fumbling with foreign mics and plugs - flap open Canon micro postpone finished - and the best my old micro DM 100 fits well with my new HF G 30 !!
