You buy a camera lens to over 1000 euros, the Nikon 70-200 f / 4 example provided to you with a cloth bag which offers virtually no protection ... You put yourself in search of finding a cylindrical case to transport it safely in an ordinary bag on the day that you have enough space in your camera equipment bag ... you see that for these cases, no one is damned to give you the information about useful dimensions (internal) diameter and length. This would allow you to know, among other things, if the visor will be able to enter the case. So we fall back on this kind of product ... Cons: a little bulky, not very aesthetic and less ergonomic than would have been perfectly adapted case. Plus: good protection material, which is most important after all. I had the opportunity to compare the protective square made in France equivalent (same brand ID) manufactured in China that costs 5 euros less. I'm not sure that, objectively, the French product deserves to be paid almost 40% more expensive but these days ... too bad for objectivity! The most economical solution, the best quality / price ratio would clearly be "made in seamstress your knowledge" because this is hardly a square of fleece fabric with Velcro sewn around ...
