Amazon’s customer comments

I bought three of these umbrellas over a year ago after reading about them in a Strobist article. They have been fantastic. They hold up as well as the much higher priced brands after over a year of commercial field abuse. Their most endearing attribute is that they double fold when collapsed, so they are ultra compact when folded. Best of all, I have not had a single failure of any kind since I bought the trio. I am not overly gentle with my photo tools, and this product has never let me down. Buy a lightweight, ultra collapsible stand, bungee the two together, an you have a portable light studio for your Speedlight and Pocket Wizard combo that is as as compact as a small folded newspaper, and pleasingly light to boot.

One review mentioned that the umbrellas included the Adorama logo on the outside perimeter. It’s very true. I was surprised to see dual brands printed there, but after considering that my first purchase from Adorama was in the early 1980’s, and that I have bought everything from film to large format lenses from Adorama since that time without a single complaint, I welcome the Adorama logo as an old friend, and I’m more than happy to display the name wherever I shoot.

This is a great umbrella. It’s pretty large, yet it folds up very compactly (a little longer than a foot) when you collapse it.

I’ve never tried any other shoot through umbrella before because it’s my first strobist gear, but I feel like the construction is a bit flimsy. It’s completely my fault for not weighing down the lightstand while shooting outdoors, but it blew over and it bent the metal connectors really bad. The metals used to construct this umbrella are very flimsy and even when I’m clamping it into my lightstand, it leaves an indentation on the rod.

Other than that, the shoot through umbrella is great. It spreads the light onto your subjects and evenly lights them.

Just be careful with how you handle this umbrella… It’s very fragile.

Canon Digital Camera Wide Angle Lens

Photography has come a long way. One of the more popular camera brands is Canon. It has diversified its product offerings but continues to focus in their series of digital cameras, both point and shoot and SLRs. There are various factors that need to be considered when buying a camera, particularly the Single Lens Reflex cameras. While most consumers would prefer a camera with high megapixels, enthusiasts would be busy arguing which lenses to use. A case in point would be the Canon Wide Angle Lens.

Aside from the price and form factor, the type of lens is an important criterion to consider. There are quality lenses and there are those that appear to be imitations. The Canon Wide Angle Lens is perhaps one of the more popular choices among aficionados. This is because of the quality and the additional features that help deliver stunning photographs.

The Canon Wide Angle Lens has patented technology that allows rapid focusing. This is ideal when taking a photo of subjects in motion or even in events that need to be captured in succession. It covers a wider spectrum which makes it an ideal choice for landscape and portrait shots.

It is important to be aware of the features of the lenses that you intend to purchase. Though they may look the same, they can differ in so many ways that will ultimately affect your photos. While the Canon Wide Angle Lens is a popular choice, it is also important to first determine what you are really looking for in a camera lens. You also have to consider the price because lenses don’t come cheap. But if you are well-informed, you can find lenses at reasonable prices, whether online or in shops.

Here I review one of canon digital wide angle lens,
