The Olympus E5 with Olympus ZD 14-54mm f/2.8-3.5 II zoom lens and Olympus ZD 50-200mm f/2.8-3.5 lens could be supplemented with a Olympus OM-D E-M5 camera and the following lenses:
The Canon 7D with EF-S 10-22mm and EF-S 17-55mm f/2.8 IS could be supplemented with a Canon 5D Mark III dSLR or Canon 1D X sports dSLR and the following lenses:
The Canon supplimentary kit will be much bigger, heavier and far more expensive and you will need much larger tripods, tripod heads, filters, backpacks, etc and these will create issues for travel, in particular, flights with their 7.5kg limit for cabin baggage.
If you are a Canon full frame user, you may find the Micro Four Thirds system compact kits are a better fit than a cropped sensor dSLR such as a bulkier Canon 7D with its poorly matched, or in the case of EF-S, sub-standard lenses.
The situation for Nikon users is similar to the issues confronting the Canon user above.
