Review on Canon EF-S 17-85mm f/4-5.6 Image Stabilized USM SLR Lens for EOS Digital SLR Cameras - White Box (Bulk Packaging) by Akemi Akio ᠌

A wonderful, insightful, and precise optic that produces a magnificent image. Yet, there are a few benefits and drawbacks associated with it. You need to have the ability to use those, just like any other complicated piece of technology. Personally, I made it a point to avoid using it at really long focal lengths and with the aperture wide open unless it was absolutely necessary to do so. Even though there will be some blurriness due to the fully open hole, it might not be a problem for a portrait because the camera has the ability to switch the hole on automatically in the automated (P or A) mode as it gets dark. When you need a wide angle, it's even worse. There is not always a location available to enter a room (apartment). A crop ratio of 1.6 means that the effective focal length of the lens is 27 mm. This is already far broader than 24 millimeters for conventional zooms on cameras that have not been cropped (24-70). And if we take into account the fact that it soaps a little at the extremely short focal lengths, then there are even fewer workers remaining in the industry. To put it another way, you need to have the understanding that any zoom that has an increase that is greater than three times will have some problems in common. Have not yet acquired the skills to accomplish more.
