Have used this for almost 9 months. Easy to use, very portable. Works well in almost any vehicle. Stays in place in most vehicles. Only problem was using it in an older car with a very steep dashboard. Hold GPS unit in place and can be moved from one vehicle to another or easy removed and put in glove compartment or hidden on floor unlike suction cups that leave a ring in the windshield even when removed letting potential thieves know you have a GPS.

I bought this SDHC card for my Canon point and shoot and have not had any problems with it. The card is reliable and the transfer speeds are fast.

I went from a small ipod nano to this new 32GB ipod and now I know what I have been missing out on. I can’t believe the storage and how fast it works. I am very happy with my purchase.

This book written more than half a century ago is an excellent example of what goes on in a young man’s life as he searches for his psychological self in the mirror of society. He is caught in the sexual travesty of the time as he seeks something good in the midst of a misadventurous society and college life. Salinger’s insight into the psychology of a boy-man is unique, and the cause of this book being required reading in schools. It remains high on the list of books even to this date.

This is just about the best vacuum cleaner I’ve ever used. My home is undergoing remodeling so we are constantly struggling with dust and other things tracked onto the floors and rugs. This little lightweight vacuum cleans it all up in short order. It’s not too loud (my cat is not afraid of it) and it is easy to switch from upright to the hose and tools. Just one issue – I would prefer the tools to be a little wider. It’s hard to vacuum a chair or couch with a five inch wide upholstery tool.

I now have bought two lenses that were not designed for the smaller digital camera sensor, and both consistently fail to autofocus, the Sigma 28mm and the Canon 50mm f1.8 II, both relatively inexpensive lenses, and both designed for film cameras I believe. I was able to get both to focus most of the time by using my “live view” focusing, but it is slow and you can’t use the viewfinder. I just couldn’t justify keeping this large, heavy, no doubt very high quality lens if it was going to be that difficult to use.
The kit lens that came with my Canon XSi focuses much more reliably, maybe because that lens is designed for small sensor cameras.

I refused delivery of this product and it was returned. I have not received a refund. Its been a month.

Let’s get the bad out of the way first. There are two things I don’t like about this lens. First, the auto-focus is a little slow, it should definitely have been a bit beefier. Second, it went on sale right after I ordered it for over $100 less than what I paid.
Be warned. the 1.4x teleconverter that appears on this page as an accessory does NOT work with this lens. The optics in the teleconverter stand up too much to allow it to attach the the lens. This teleconverter works great on my Sigma 400 APO, though.
The lens is heavy. I think that’s a good thing. I do not feel that a person could reasonably be expected to use this lens without a tripod or monopod for very long. While 4 or 5 pounds may not seem like much, it gets heavy after 20 minutes or so.
I’ve used this lens on both a tripod and a monopod successfully although, I prefer the tripod because I feel it gives me smoother movement with the lens (maybe I’m just too shakey for a monopod in general).
The pictures are amazing. Due to the specs of this lens, I’m able to photograph a wide variety of things that would have otherwise been unattainable for me. Birds, animals, even the moon. I’ve been overjoyed with the quality of the photo’s I’ve taken with this lens!

Overall this is a good lens. Affordable, compact and very light weight. IQ is also good and it has great macro capabilities. So, you may ask, why I’m rating it *** only? The reason is because AF when using it as a macro lens is very difficult to achieve and very inaccurate. You need to take many shots of the object moving the camera slightly each time and with luck one shot will be focused right where you wanted. You also need to get very very close to the subject, which is OK when photographing flowers but not as good with insects and other live creatures. The lens becomes attractive more because of its low cost (compared to other Zuiko lenses) and the fact that it can be used for portrait and general purpose photography (keep in mind that a 35mm lens on a 4/3 system is in reality 70mm). Again, recommended only if you are on a budget and want to have a small, compact macro lens without spending a lot of $$$.
