Summary: I looked at all my choices for the Nikon D300 with the kit lens 18-200mm and decided after spending all the bucks, I better protect my investment. I've walked the streets of NY city and rode subways and never worried about bumps and scratches. For me this gave me piece of mind.
Pros: Fits like a glove, Good Protection, Use it with zoom attached, Weatherproof
Summary: I expected this case to screw in to the bottom of my D300 via the tripod opening as my N90s case did. But this case merely stores your camera and is cumbersome as it lacks the zipper opening of other cases. I got the Optech which fits like a glove, offers sufficient protection and is half the price.
Summary: Travelling through europe recently with the Nikon Semi-Soft Case was very convenient and a life saver. I was able to carry it in a small backpack as I walked around. with this small case i kept my Nikon camera inside and well protected and it gave me the freedom to pull it out and use it whenever i needed to capture a moment. I do wish it had a small compartment (maybe inside) to hold an extra battery or flash card.
