I have an XSiwith a Tamron 17-50mm f/2.8 ($420ish) and a50mm f1.8 II ($80ish). I alsohave a pair of430EXs and a Canon Speedlite Transmitter ST-E2. I highly recommend the Tamron and for the money it's crazy not to have a Nifty Fifty.


I'm stuckusing anancient (circa 1997) 75-300mm f/4-5.6 USM II it's slow in every way and seem to sap the color from any picture it's used on. (I know this is partly due to using high ISO to counter it's slow aperture.) So, I can't personally recommend a long lens. Although I am seriously thinking about selling my Smith &Wesson 500 toget a200mm f/2.8 L II USM ($750ish)because I tend to use only the longest focal lengths (200-300mm) on my 75-300mm andthe 200mm f/2.8 L II USMis fast and fairlycheap not to mention relatively light and inconspicuous, being a black lens.
