Beware of Cotton Carriers!
I bought a Cotton Carrier to lighten the load on my back while transporting heavy lenses during avian photography.
I soon found the item's fatal flaw: There is a thick velcro strap that keeps the barrel in place. Once you move to detach it (no matter how gentle you are) the ripping sound scares away any bird within 50 yards. I contacted the company about the issue, but they were utterly unresponsive. I eventually had to pay a shoe repair place a good bit of money to fashion a quiet clip release in its' place.
How stupid of Cotton Co. to release a product, used 50% by nature photographers, with a screaming loud safety strap.
Buyer beware!
Let Me, Respectfully, Help You Understand
1) The company is absolutely aware that a great deal of its' product users employ their units with a wildlife focus.
2) No one can always predict (and thus "unclip" early) when a bird shot may come before them. Have you been out birding before?
3) "Fatal Flaw" refers to the demonstrable inability of a given product to be successfully used for its' intended purpose. The velcro, which is essential to stabilize a large lens, defeats the key reason the avian photographer is out there in the first place.
4) If "fatal" is too dramatic a word for you...I will substitute "essential" in its' place.
Sorry if I sound a bit harsh (it's not personal, I assure you), but my aim is to make other wildlife photographers aware of the real situation with this item before they purchase. I only wish someone had done that for me. I really do.
