This is for you 60Der's. This one of the main reasons I sold my 7D. It is a lot cheaper than the new Electronic Z-Finder or Redrock.
What other HDSLR can do this.
The L-Finder. It consists of a Hoodman Hoodloupe 3.0
Here it is on Amazon:
Hoodman H-LPP3 HoodLoupe 3.0 Professional 3-Inch Screen Loupe
and the Hoodman HCAMM Neoprene Camorder Mount Strap
Here it is:
Hoodman HCAMM Neoprene Camorder Mount Strap
This works well. Other loupes would be too heavy for the 60D LCD in that it would swivel on its own.
It is also being offered one unit.
