A Really Nice Improvement

I photographed my first Elk in Yellowstone using the original rain cover for a 600mm lens. When i took the shot, it was misting at first, then began to rain lightly. My equipment was never in danger of getting wet. A great product made even better. Thank you Think Tank. George Ligon

Another quality item from the ThinkTank crew

I already had the necessary eye pieces to fit my Nikon D750 so when I purchased a D850 and D4s I needed the different connection type. No hesitation to get this. The rain covers for the 70-200 and 300mm lenses are top quality and beat anything else I have tried to keep out the rain.

Great system

Different camera, different eyepiece needed...affordable, interchangeable eyepieces are a hallmark of this great system. Every time I'm at an event I have to chuckle at the collection of garbage bags, shopping bags, even towels I have seen other photographers using to try to keep their equipment dry.
