I use this for my mirrorless Fujifilm X-T4 and it works fine with the Fujinon 16-80 zoom kit lens and, zipped open to fullest length, with the Fujinon 80mm macro lens, (6.25" long and 3.5" diameter, sun hood in stored position). You do have to put the little raincoat elsewhere to carry the Fuji + macro, especially if you use the chunky Fuji neck strap, but hey, it's so hard to find ANYTHING that fits the Fuji stuff, I don't mind. I really like the neck strap and sturdy handle. Neckstrap over the opposite shoulder helps balance the weight while hiking. Works great for me.

I mostly carry a backpack with me and prefer to use my hiking ones with an insert or two. I put this holster inside it to protect the camera during transportation and have my lenses in a Tenba BYOB. Then, when it's time to get walking I put the camera on a Peak Designs capture clip and either leave the BYOB in the backpack or hang it around my neck for really easy lens changes. By having two separate cases it means that don't have a huge insert to faff with each time a lease change is required. The beauty of this holster is the expandable section, which means that if I don't want to carry all my lenses, I can have my G9 with the 100-300mm mounted or a prime mounted and a second prime in the bottom, depending on what I want to shoot. It works very well for me and, as is usual for ThinkTank, the quality is second to none.

I have a sony 6300 and I'm SO tired of switching bags. This holster allows me to switch lenses on my camera but I don't have to switch bags. Just unzip and push the bottom out. The holster is made really well. It's padded where you want it. There are a couple pockets but the larger pocket is taken up by the rain hood. I've fit a few things in the holster but it is mainly a minimalistic bag. It does have a bit of padding on the shoulder strap. If I had a full frame camera I would def want the larger size. For me I can fit my mirrorless and up to my 70-200mm lens. It's a bit pricey but I can tell you from previous Think Tank purchases these bags wear very well. I have a Think Tank backpack that's several years old and it is still in very good condition.

Exactly what I was looking for. The extension with a zip allows me to carry my camera together with lens hood

Works fine, but you have to remove the rain-coat from it’s pocket and put it somewhere else in order for a Fuji X-T4 to fit easily into this. The extension is nice for Fuji’s 80mm macro lens.
