Pretty good bag! Nice and good on the shoulder. However, I wish I had bought 10L. It felt a little too small for the following content:
Sony A6000 + Peak Design Slide Lite Strap v3
Canon FD 50mm 1.4 + K&F Concept Sony E-FD Adapter
Sigma 30mm 1.4
Sigma 16mm 1.4
1 extra battery
1 Polarization filter + protection case
1 lens brush (Zeiss)
1 camera cover
1 Sony E rear lens cap
In this case, Sigma 16mm 1.4 was the big top, so it got the best spot if you put it on the camera. However, my fault is not to realize the size limitation with this little shoulder bag. One solution to that is to buy a Capture Camera Clip (https://www.peakdesign.com/collections/clips/products/capture), and put it on the side of the bag, and have the entire case for lenses only. Or to buy the 10L version of this bag.
Even so, very satisfied with what you get for the price! Smart design and stylish!
