You can read camera lens comparisons until your head spins, but chances are that the Tamron 17-50 Nikon is always going to remain a good option. You might find lenses that perform better, but you are going to struggle to find anything that can couple that performance with a price tag that is not overboard. Tamron has been making a name for themselves with quality lenses that come at a reasonable price tag, and this Nikon compatible version ranks amongst their best. Its focal range makes it a very versatile choice for any photographers who want an upgrade from their standard lens. It does not matter if you do landscape or portrait photography, as this lens can do it all. You might not get the same results as you would have from a lens dedicated to either, but for the price you can’t really argue. I have even seen professional photographers with very expensive lenses use this one as a backup because it is so inexpensive.
