Hi,

I'm looking for a 5"-7' field montitor to mostly pull focus and to make adjustments (aperature, iso, shutter)..I don't want cheap but don't want to spend a fortune either. It will be used for weddings off a dslr 7d camera with hdmi.Budget is around $300
Is there any recommendations?

Thank you!

Have you looked at http://www.aputure.com/vs-2-FineHD ?

Aputure VS-2 FineHD Kit 7″ Monitor First Look. This Kit Is Loaded! | (http://eriknaso.com/2015/12/23/aputure-vs-2-finehd-kit-7-monitor-first-look-this-kit-is-loaded/)

SmallHD is amazing - pin sharp and good focus peaking

I noticed most of these monitors require sony batteries...I was hoping for a 12v battery pack so that it can last a whole day (or close to it).

How long do the sony batteries last on these monitors?

Thanks

I use 2 NP-F550 batteries on my SmallHD and that's enough for ceremony and speeches with some to spare but of course you could use 2 NP-F970 batteries and it would be good for all day!

+1 for the Black Magic Video assist. Canon batteries. Takes two and are hot swappable. Plus it's a recorder as well if you want it to be.

I got a 7" Lilliput field monitor. The resolution is good it's around $300. SmallHD is probably lighter but at 2-4x the price.
