Shimoda Core Unit Large Mirrorless Modular Camera Sort EVA Divider System for Mirrorless and Gripless DSLR Body, Side Access up to 12cm Tall Outdoor Pack Storage

I live Shimoda designs... This is my second bag, and now I have a 40L and a 30 L. This large mirrorless is what's recommended for the Action X 30L series, but I'd recommend sticking to the medium instead. While I do love the carry capacity, it eliminates about 80% of the upper compartment if I don't unfurl the top. Basically I have to tuck the upper section to a side because the large cube takes up most of its space. That said I can carry 2 Canon R6, 24-105, Sigma 150-600 C and some adapters and teleconverters.with room for dust bulb and batteries. You just have to get creative on its layout. Bottom line, if I had to do it all over again, I would have gotten the large cube for the 40L bag, and the medium for the 30L. In the 40L I have the DSLR medium and small cubes.

It fits the Explorer 30L exactly. You have to push it in completely. It fits perfectly without any extra room to spare. After that I removed the top pocket so my bag only has the core insert and nothing else. I found out that it can be removed from Youtube. If you do not remove the top pocket, it will rest on the core insert and flop around. I am so glad that I bought the L version. I can put in my Canon R6, Sigma 105 f1.4 (it is a monster), batteries and the 3 more RF prime lens. It is amazing! I also put in the waterproof cover for the insert. That required some effort. I left one side uncovered so that I can open the insert to get my equipment. I want the cover to cover the base of my insert. It is well padded and I rearranged the padding according to my lens. The weight was very well distributed and it was comfortable to carry. I made it a point to put all my heavy lens right at the top of the insert as I do not want the weight to hit my back when I walk. The weight was bearing on my shoulders but with the broad carry straps it was so much more manageable. Indeed it was one of the best camera bag that I have carried but it is far too expensive. Even for the core insert, it cost so much. Nevertheless it was very well made and I believe it will last many years thereby helping me to recoup my investment.

Item was a bit slow to arrive I guess due to import from another country. However, it is exactly as described and well built. I recommend this product and the seller.

Fits easily in the shimoda 35L size backpack. The 200-600 lens fits inside however the 400-800 is just slightly too long.

This is a big upgrade for my explore 35 (v2). 200-600G attached to my a6700. 70-350G, 16-55G, 11mm, dji mics and peak strap. You lose space at top of bag but it is absolutely worth it. See in the photos, I can still put my jacket on top of lenses as well as laptop and it is very comfortable on my back.
