Cover Size Selection for my needs.... What Outex Cover size is ideal?


What Outex cover sizes are available?  Which one is best for my gear?

There are 3 current Outex underwater housing cover sizes available; 100, 110, 130.  
Larger covers can be used for smaller cameras, but not the other way around.  

Small (Entry); designed for compact and mirrorless cameras, but works with DSLR 
Medium (Pro Kit Regular); most common – fits most cameras other than full-body.  
Large (Pro Kit Large); full body cameras or cameras using a battery grip

The Entry Kit ships with Cover 100X (Small).  "X" denotes no opening for the glass
The Pro Kit ships in regular or large sizes (110, and/or 130), depending on your camera or specific choice. 
All Pro covers work with all/any rear and or front glass options.

Ad-Ons, Accessories, and Compatibility

Each size comes in various formats that accommodate accessories and ad-ons, such as Tripods (T), Lighting/Flash (F), Tethering (T), Cable Adaptors (T), Pistol-Grip (G), Entry Kit (X), etc.  

All Covers are backwards compatible, so existing Outex gear (lenses, viewfinders, adaptors, etc.) work interchangeably with any/all of our covers.  

The Outex system works like LEGOS.  You can build, mix, and match as needed.
