The look of the bag is certainly a matter of taste, but it fits perfectly for the Oly retro design and the workmanship and quality of materials used is perfectly fine. The padding is sufficient in my opinion completely. The absence of countless extra bag, straps, zippers, hooks and loops increases the practicality enormously - that's something that in other bags often annoys me. Straightforward and equipped with the essentials, so should be!
The following parts can fit: Olympus Pen | Pana Lumix 20mm pancake | Oly 45mm / 1.8 | Oly Zoom 40-150mm | Raynox achromatic including step-up adapter and snap version | two extra batteries. To illustrate this, I have uploaded a photo. The listed items of equipment the bag is well filled, more is not the best of intentions.
Conclusion: who can cope with the capacity and the design like that makes the Street Bag nothing wrong!
