The camera is easy to reach, it wears well on long trips very enjoyable and he should still press times, you can just change the page. By raincover one is also well prepared for bad weather.
While it is a bit tight, but I can currently store the following equipment in 3N1-20:
- Nikon D90 with battery grip and lens
- 5 lenses from small to large (Nikkor 50mm to large 70-300)
- Big flash
- Various small items and filters and
- For a raincoat and 2 apples in the upper compartment there is space.
The only downside, but which is not particularly bother me that one usually reaches the lenses on the opposite side of the opening only by discontinuation of the backpack.
