While I ... (a former users opinion)
Usually am one to snap up the better equipment, I have to say that a lot of people have opted to go with the 18-250, which does cover a lot of ground, but WITHOUT a HVL-F42AM or HVL-58AM flash, it can kind of a "dog" indoors. It simply cannot get enough light to take good images. You need to know the limitations of your gear.
I sold mine with the SONY α100 a couple of years ago ... and while I really did not like parting with that convenience lens, it did offer an unequivocal one-lens wide solution, outdoors, to the buyer.
On the α100, it is probably the best match-up for the lowest cost, but you do need a 50mm f/1.8 lens to augment going inside, if you do not have an external flash. With the 50mm, you can successful use the pop-up, and while the images will not be "great", they should get you along until you are ready to upgrade to better optics.
Pant, pant, pant ... anyway, if you are strapped for funds ... the TAMRON 18-250 delivers the best looking images of the three -> the true bargain.
Again, all of them suffer from light starvation, indoors. Keep that in mind. :cool:
TAMRON SP AF 28-75mm f/2.8 XR Di LD Ashperical - again
The TAMRON SP AF 28-75mm f/2.8 XR Di LD Ashperical
- for the price, is one of the best lenses in its class.
- SONY adopted it as the kit/base lens for their a900/a850 offerings
- Although designed for a full frame mount, on an APS-C sensor camera, it becomes effectively a 42mm-112.5mm (not a bad walk-around lens, to be sure)
- The photo award given by EISA (European Image and Sound Association) is one of the most prestigious and internationally recognized awards in the industry. The jury, representing the leading photo magazines in 15 European countries, annually votes to give the award to newly released products in recognition of their contribution to the development of imaging technology. The Tamron SP AF28-75mm F/2.8 XR Di zoom received the award for 2003-2004.
Look, if you are going to choose a clear winner, for the money, this lens is the clear choice. The Minolta-version is the same lens, just rebranded by contract.
Do I own one ... yeah ... I had two of them. Canon and SONY mount. Still have the SONY mount.
