At least for the last 10 years or so, I have typically bought camera lens covers for protection often from LENS coat and ROLAN pro. For the last year or so I have completely quit using them because I feel they make using the zoom ring and focusing difficult. They also stretch out over time making them annoying when you’re trying to shoot. The only thing I use now is the front hood of the 600 mm prime lens. This is only because that hood cost so much. I just think it’s a more enjoyable and much easier experience using the lens without these things on there and honestly don’t plan on ever buying one again at this point. I keep all my gear insured and God forbid something happens, I’ll just turn in a claim I suppose. It is also very nice having the switches exposed at all times on the lens in case you need to make a quick change without having to remove the Velcro cover. I honestly can’t believe you how much better of an experience it is especially with the big prime lens not having one on there anymore. Just curious if others find these things as annoying as I do lol.
