Got this for my new Nikon Z 400mm f4.5. I was worried about the diameter, but there is just enough room (hood a wee bit tight pulling the lens out, but easy enough and may loosen with time). Tight fit in both width and depth when both the hood and tripod mount are on in their normal shooting position. With the hood flipped in shortage position it is a very snug for both lens and my Zii body. So more than enough room for the lens by itself, including extra filters and the like in the top mesh pocket, and in fact it is perfect length for the lens with hood flipped and a 2x teleconverter attached...which I think will be my default use). In general do not like zippers on lens cases (always the first thing to go bad), but I am very happy with the case overall: Materials seem sturdy, padding seems adequate for storage inside other luggage or bumping around the car in the field, and there is a carry strap with multiple hooks and belt fold to attach this case to other backpacks or luggage. The price point for this case is excellent for what is delivered, and I am very happy with this purchase.
