Depending on your current arsenal, you might add in the Forgotten 400: http://luminous-landscape.com/review...tten-400.shtml The comparison to 100-400 frames are telling. It tells me that this particular sample is defective, unfocused, or poor tripod technique was used. My 100-400 @400 is way sharper than that, at f/5.6. -- John P Sheehy |

The 100-400 also focuses faster; but again, given the cost, size and weight, many could be better off with the 75-300. The 100-400 is a lot sharper than it appears to be; first of all, IS doesn't preserve tack-sharpness 2 to 3 stops; maybe only one stop. it is the low-frequency jitter that the IS works best on; not the high-frequency jitter, so lots of people are using the 100-400 at un-hand-holdable shutter speeds for tack-sharpness. I would put the 100-400 (my copy, anyway) at having about 2.5x the angular resolution at 400mm than the 75-300 has at 300mm. If you can get enough light for fast shutter speeds, or use flash, the 100-400 is still good with a 2x TC. -- John P Sheehy |

Wayne, These were all taken with a DRebel (300D) and the 100-400 L IS lens. http://www.pbase.com/rkircher/100400 I personally love the lens. It is heavy and the push pull zoom takes some getting used to but the results are treat IMHO. As to why I bought the zoom over a prime? Well look at the focal length numbers on the pics in that gallery and I think that will be clear. I wanted the flexibility of range that you can't get with a prime lens and I didn't have enough $ to buy multiple lenses or the desire to constantly switch lenses. HTH -- Rob |

Rob--
Thanks for referring me to the site. That shows very well the versatility and results from the lens. So far I'm leaning toward the 100-400 because it encompasses the 300 and looks favorably sharp. --Wayne "Robert R Kircher, Jr." wrote in message ...
