  • fits 600mm lens with camera attached, more designed to fit long lens than lowepro and thinktank long pouch bag.

• Advantage of shoulder bag
  • Gear right at hand level compared to backpack or sling bag
  • let carrying a bed for your long lens sleeping horizontally inside to avoid lens tip landing on ground.
  • your back can get a breeze of air compared to backpack
  • can give you a lot of loading slots when put on ground.
• Disadvantage
  • Shoulder can swing around your shoulder, and can slide in to front if you bend your body forward, causing a big motion of gear bag hitting forward or hitting ground if strap is long and you are bending low

• Example:
  • Lowepro Nova series (retangular base shape) and stealth report series (D base shape)
  • camera + 150-600mm = around 40cm long
  • camera + 500mm f4 = around 50cm long
  • camera + 600mm,800mm prime = around 60cm long

Stealth report

nova

• nova sits in the middle of Stealth Reporter and Format in term of weight
• and seems it the nova line replace Stealth Reporter and Format together as middle weight serious bag
• nova XXX version is more round like stealth reporter than nova X line.

Format

• Ref:
  • YN560III,IV flash full height with foot is about 19cm tall

Urban

• sigma 100-300 f4: 23cm
