[Fot] Video question

[Greg & Alison Blake]

Alison has a question for those of you using video cameras.

 

She wants to get me a video camera that we can swap between my 3 and dad's
4.  We have been looking at the GoPro cameras.

 

Questions:

What are the advantages of going with the latest $300 hi-def version over
the $149 standard definition?

Do you have to buy GoPro's SD cards or can you buy them at your favorite
tech store?

 

Would also like opinions regarding wide (170 degree) vs standard lens.

 

Thanks in advance.

 

Greg
