Lowepro 45AW II Bag
The Lowepro 45AW II Bag can hold a Sony a7rII with a 55mm prime lens quite easily. I suspect it can hold a smallish zoom lens too. I find the Sony a7rII tends to wobble about a tiny bit with a Sony Zeiss 35mm f/2.8 lens as there’s extra room; it’s nothing to worry about, but it’s certainly more snug with a 55mm or a 21mm prime lens.
As you can see in the photograph above, there’s still a bit of room with the Sony a7rII and 55mm lens mounted, even with the hood.
The bag itself is a fairly simple design. At the front there’s a compartment that can easily fit spare batteries or a filter. There’s room for a remote control too. At the back, there’s a belt loop, and an additional compartment towards the bottom that holds the rain cover (included and sewn onto the bag–you will not lose it.)
The Lowepro 45AW II bag has many uses
I bought the Lowepro 45AW II Bag because I wanted a side bag that can be strapped onto my main backpack via paracord, when I hike the Pacific Crest Trail in 2017. Using paracord, I can loop it through the belt loop and strap it onto the metal side frames of my larger backpack I intend on buying. I have also found myself using the Lowepro 45AW II Bag on its own quite frequently. It is extremely small and it’s ideal if you just want to quickly go to the shops, a restaurant or whatnot without having to bring along a big backpack. For situations where I want to take more equipment, I take the Lowepro Photo Hatchback 22L backpack.
