The main differences are the procedure for setting up the beauty dish, the sizes available and honeycomb grid included.

The Collapsible Beauty Dishes is foldable and compact which makes it easy to carry around. Here is a YouTube video which may give you a better ideal on how the collapsible beauty dish works.

How To Set Up Your Pixapro Collapsible Beauty Dish

To set up the Beauty Dish, you simply have to push down each rod until they lock into place. To fold the Collapsible Beauty down you would again just need to push down on each rod and release the locking mechanism. The grid with this will also have a much larger spread compared to that of the standard version, the small the spread of the honeycomb the more direct the light becomes.

The standard version of the beauty dish will be made of solid metal, which means that minimal setting up is required. This type of beauty dish is great if you are using it in a fixed location or studio, simply attach is to your light and you’re away. The honeycomb grid of this beauty dish gives you more of a directional light as the honeycomb is much smaller than the fabric version.
