Lenses for my D Rebel

Thanks for the info. 300mm is where I maxed out on my 35mm SLR, and the 70-200mm gets to 320mm with the Digital factor. I bought a doubler for my 35mm and used it once because of poor pics. My question is will Canons 2x converter give me great results? Also, does the lower f stop give me that much better photogragh, in comparison with the price?

I personally don't like the converter. In many cases, it deviates and gives too much picture deviation & distortion. In my opinion, the fixed lenses give the best picture result, regardless of inconvenience.

Although the lower F-stop lense is for the brighter picture, the lower F-stop does not guarantee you always a good picture result.As the matter of fact, it's the detailed lenses inside the zoom lense that do the works, for instance, sharpen image, correct light color and rays, and gather the light volume and direction. The Canon 70-200 mm F2.8L, I previously mentioned, will keep the same 2.8F-Stop throughout 70-200 mm, unlike many zoom lenses where F-Stop changes over the different focal length; therefore, it gives camera's owner less concern over the in consistent aperture factor. In addition to that, the larger L-lense diameter of 77mm significantly edges out the lighting and contrast over Canon's regular 58mm zoom lense. The burden will be the money to be spent on the lense. Personally, I'm quite happy with the 3 Canon L-lenses I have. Choose wisely. Good luck.
