Incredible Quality and Value of Tamron 28-75mm Lens

May 11, 2010

I really like my photography equipment. One of my lenses is a Tamron 28-75mm f/2.8 XR Di LD and it is my workhorse lens, easily getting the greatest amount of use of my three lenses. The lens is also an incredible value when you consider the image quality, which is Canon L quality for a fraction of the price of an L lens. The build quality is up to par with an L but the image quality is and, since I am fairly careful when working with my lenses in harsh environments, I’m not too worried about ruining it – especially when you consider, at $459 (according to B&H Photo), I could buy two of them for the equivalent focal length Canon L. Don’t get me wrong, the build quality is not cheap, but admittedly the Canon L lenses are in a different league in that regard. As for image quality – it is simply amazing. Below is a shot of my two-year-old son taken using the Tamron lens on my Canon 40D with my flash bounced off the ceiling. Click on the image to view a 100% crop. As you can see from viewing the 100% crop, there is tremendous sharpness and detail in [...]

Canon AF-On Button

January 5, 2010

Up until recently I had been a recomposing monkey when taking portraits or family photos. See, when using auto focus (AF), I like to use the center focus point, focus on what I’d like to be sharp, and then recompose the shot. The problem that crops up though, is that once I recompose and press the shutter button halfway down, the AF locks on something else (the new spot where the center focus point is), ruining my previous focus setting. To compensate for the problem I had been pressing the shutter button down halfway and holding it while I recomposed the shot, but that leads to a problem where I have to redo all those steps every time I press the shutter. What a pain in the neck, especially if my camera’s on a tripod. So, as a result, I had been searching for a solution to this problem and ran across the AF-On button, which allows me to separate the AF functionality from exposure and thus allows me to lock the AF so I am free to recompose the shot. I’ve been experimenting with using the button and am very pleased with the freedom it’s offering me. Here’s what I now do: Zoom to [...]
