I am getting a Rebel shortly and I currently have an S1 IS with the teleconverter. It multipies the stock lens 1.6x. Since I am a newbie I want to know what zoom lens for the Rebel will give me the same amount of zoom. I have been looking at the Sigma Zoom Telephoto 70-300mm f/4-5.6 APO Zoom Macro Super II Autofocus Lens and the Cano Zoom Telephoto EF 75-300mm f/4.0-5.6. I plan on using it take pictures of birds in my yard. I have had good luck with my S1 but like the SLR lens options. Any input on either of these lenses would be appreciated.

Your S1 is 38 - 380mm and with a 1.6x converter it becomes a 60 - 608mm :idea:

The closest 10x ratio zooms with this kind of reach are:

... 300mm will be shorter from what you were used to even with the crop factor!

Thank you for the reply. That is exactly what I needed to know. Now I can begin lens shopping.

I suspect his current camera is a 38-380mm 35mm equivalent. My experience with my old Pro90IS and a 1.7TC was severe vignetting unless zoomed all the way.

If he wants a good lens with a lot of reach, he could go with the the Sigma 70-200 f/2.8 (112-320mm equivalent). Add a 1.4TC and it becomes a 448mm f/4.0 equivalent. This combination would cost about $850 and provide afairly brightlens and without the TC makes a very nice portrait lens. It's not a feather weight, however.

The IS isn't available with this combination. That feature is available in some lenses, but either adds to the cost or reduces the quality of the lens. An example of this combination is the Canon EF 70-200 f/2.8 IS that costs about $1500 and about $200 more for the 1.4TC. Without IS, he'll have to use a monopod or tripod at the long end.

There are some lower quality lenses with IS that cost less than the above combination. It's going to be, like everything else in life, a trade-off.
