The 70-200mm focal length has been the standard tele-zoom choice for many years, offering near normal to a good tele range that suits many practical purposes. Yet, quite a few stock-in-trade 70-200mm lenses had been slow or lost significant aperture as soon as you left the shortest zoom setting, making them a real challenge for handheld, low-light, or even max focal length shooting. Certainly, improvements in sensors and processors in terms of the high ISO/image quality ratio have helped. If you’re too slow on shutter speed with a variable aperture zoom you can always jack up the sensitivity. But that’s not always a great choice and it seems to force you to compromise image quality just to make up for the lens losing “speed” just when you need it most.
There was time when those seeking super-wide lenses for APS-C size sensor cameras didn’t have much choice, but new light gathering systems that distribute light evenly from lens to sensor, as well as new optical formulas from camera makers and independent lens manufacturers, have changed that point of view. The latest in this welcome new class of glass is from Tamron, with their 10-24mm f/3.5-4.5 offering. Priced at around $500 (street) and weighing in at about 14 oz., the Tamron 10-24mm is useable for cameras that require “motor in the lens” operation, such as the Nikon D40X, on which this lens was tested. The DiII designation tells you that this lens is for digital SLRs with APS-C sensors.
One look at the specs of this new Tamron zoom and you'll understand why
it's immediately attractive to anyone carrying around a digital SLR in
their day bag. Weighing in at around 15 oz and measuring just under 3x3.2",
the lens is quite the marvel of size for what it delivers in focal length and
aperture options. Indeed, if someone told me that a constant aperture, 17mm
wide lens would be this size a few years back I'd have thought they had
lost their optical marbles. To be fair, however, that 17mm is not really a 17mm
in 35mm equivalent, thus practical terms, and I wonder why lenses like this
are still labeled that way. This lens is only for APS-C sensors, which means
it has the "35mm equivalent" of a 27mm wide angle view and 80mm
Tamron's new 17-50mm zoom, available in Canon, Nikon, Konica
Minolta (read Sony), and Pentax (read Samsung) mounts is highly
portable and compact.
Photography by definition is "drawing with light." It is creating a frame around a play of light that translates to a continuous tonal image. That definition helps identify one of the most important aspects of the craft, which is first seeing and then understanding how the play of light influences the image; how it expresses the photographer's vision and creates...
There comes a point in your photographic life when you might consider making money with your camera. It might be a life’s goal from the start, and you put the time into assisting, attending workshops, and even taking formal lessons or enrolling in a school dedicated to the craft. But more often than not it’s something that occurs to you along the way, something that sticks in the back of your mind as you lay awake at night. You consider it because of your love and dedication to making photographs, and your feeling that making a living with something you love to do would be a good way to go through life. But the question remains—just how do you get started, how do you make the transition or the first step?
I must admit to mixed feelings about the ongoing “connectedness” craze. On the one hand you have to admire technology that allows you to link the images in your camera with various mobile devices, convenient I am sure for some, and that now even lets you shoot and share at one touch of a button. On the other hand I am uncertain how this has anything to do with seeing and making quality images that speak to your instincts and feelings about the world around you. I note that some companies make this connected ability the headline of their new products, while others take it more in stride and list it as just another feature.
When they first arrived on the scene digital SLRs were well beyond the means of all but the well heeled. News organizations, sports photojournalists, government photographers, and the corporate world were the first to take advantage of the new tech...
While today's multi-pattern metering system found in most DSLRs are marvels
of technology, you'll notice that almost every DSLR also has other metering
pattern options. The two main options, with variants available on some cameras,
