Note: This review pertains SPECIFICALLY and ONLY to the NIKKOR Z 70-200mm f/2.8 VR S lens and the XXXXL Size (that's 4 'X's) JJC Deluxe Lens Case. It does not pertain to any other close relative lens in the Nikon or other manufacturer's line, nor does it apply to other sizes of the JJC Deluxe Lens Case line.
For some reason, Nikon chooses to ship their $2,700.00 Z 70-200 lens with a flimsy lint-free-cloth pouch, and not any kind of reasonable container or bag that will protect the lens when not attached to the camera. Probably a cost-cutting measure. Unfortunately, Nikon ALSO DOES NOT provide a separate container or bag option at additional cost either. This means the camera enthusiast is left to their own devices to browse through multiple websites and multiple products to HOPEFULLY find something that fits this lens.
I took my own measurements of the lens (height and width, with the hood attached inverted/facing in towards the camera mount end of the lens) as a precaution when ordering a bag for this lens, and I re-measured with two different measuring tapes and a ruler just to be as certain as I could be. This lens is definitely a monster at < 4.25" across the large end of the lens, and < 9.5" tall when standing vertically on the large end of the lens with the lens cap attached. I am sure there are much larger lenses out there, but this is certainly a big boy.
While looking over several different offerings from different third-party brands, the XXXXL Size (again, that's 4XL) of the JJC Deluxe Lens Case seemed to be the size that would accommodate this lens. Now that I have it in hand, I can report that while my lens does in fact fit in the 4XL, the case is too big (mostly too tall, specifically). That said, according to the measurements provided for the 3XL version of the same case, that smaller case would definitely have been too small. Unfortunately, JJC does not have a size in between the 3XL and the 4XL.
While the size of the 4XL case is larger than the lens, the fit is still not bad. The lens fits comfortably inside the case even with the tripod collar, lens hood, and lens cap all attached. Inside the case, the lens can rotate freely, so you may want to wrap the lens in a microfiber towel to limit circular spin inside the case. Also, the lens is about two and a half inches short of the top of the case (see photos), so you may also want another towel folded in quarters (or two) to sit on top and prevent too much vertical sliding.
Other than those relatively minor issues, the case itself appears to be fairly well constructed and solid. No bad stitching joints or anchors, no wonky zipper ends or misaligned teeth. Generally good, solid construction. While I would prefer a better-fitting case MADE SPECIFICALLY for this lens, making do with this case is not the worst option. I gave this 4 stars instead of 5 solely because while this case works and is very affordable considering, it is NOT a perfect fit for my lens. Will keep my eyes open for a better-fitting solution for this lens.
