yyyymmdd to date in SQL Server 2008 R2 - null in field issue

I'm pulling raw files from DB2 into SQL Server 2008 R2. I'm staging a report with a simple table, but want to convert the text yyyymmdd fields to actual dates in SQL Server.

This works just fine - except when I hit a NULL or blank - I'm looking for easiest way to either use an IF or ISNULL or CASE - I've read a ton of options that all dance around what I'm trying to do.

This file will run every 2 hours...
