Q: 1. Hi, any idea where I can buy a top cap for the umbrella? It unscrews and falls off. It's the very end, metal piece at the tip of the umbrella. Certified service centers don't sell them. I would hate to have to buy a new umbrella for this particular piece that I'm sure they have extras for. =) Thanks!

A: Hi Albert, You could probably substitute a flat washer and an M6 metric nut. It wouldn't be as pretty, but it would do the job. You could find these at your local hardware store or the hardware department at Home Depot. Good Luck!

Q: 5. But is there really a different aperture for the cloudy and sunny setting? for years they have had this switch, but there was no stop-down when you flipped the switch, no matter what the instruction manual said or what the specs claimed. If this version changed that, it would be great to know for sure! I'd order one right now if that was confirmed. Thanks!

A: Yes the lens stops down from f8 (cloudy) to f11 sunny.

Q: 6. Hi, Profoto certainly makes outstanding lighting gear but do you think their umbrellas are worth the extra cost? Is there a visual difference? How much of a difference is there between the deep and shallow Profoto umbrellas? Thanks. Paul

A: I thought that there would be no difference before I bought one, but now after using the Deep Umbrella a couple of times, I feel that it is worth the price. The light output is nice and even, with some drop off as opposed to a normal umbrella that spreads light everywhere. Plus, I have found that the deep umbrella tends to be easier to control the direction of the light since it reflects from the inside of the umbrella instead of through it, like a normal umbrella. Finally, the construction is top-notch and the fiberglass rods inside seem much more durable that the other umbrellas I already have. The outer layer is much thicker and the steel rod is rigid. Because of the heavier duty construction the unit weights a little more than a normal umbrella, but it's not that noticeable. Paired with my B1, this is a great modifier for me on the go, rather than using a Softbox that requires me assemble it. This deep umbrella pops open and attaches in seconds.
