A 5x7 or 8x10 may always look noisy when it fills a 32 inch screen? I don't know. On the other hand I get some really great shots if conditions are right and i can get closer. Sorry about the blah blah....what I'd like is some advice on a great quality lens in the 500 to 600 mm range with auto focus that will work with my nikon (only because i've read that the manual focus on those is very tough to deal with) and some opinions as to whether i'm causing myself trouble by using my tv as a monitor. thanks to all. There is such a curve to this stuff i can use all the help i can get.

Unfortunately, you do not give enough information for anyone to make a definitive recommendation. So I will make an assumption that your working distance will be 200 yards (600 feet). In that case, a Nikon 500 mm lens will give you a field of view of about 19 x 28 feet. If you add a Nikon 2.0 teleconverter, your field of view will be about 9 x 14 feet.
As for landscape lenses, there is a "newbie notion" that only a wide angle lens should be used. It is typical of newcomers that they usually want to include the whole world in their landscape shots. A wide angle lens will make a mountain range look like a row of low hills. There is no one "best" lens for landscape work. It all depends upon the scene and the image the photographer wants.

Do teleconverters degrade the sharpness of the picture? And for a non-related question, what is exif?

When you use a convertor you're adding glass. Anytime you add glass, and even if it's a quality glass you are changing the light entering your camera. You will have to compensate with your exposure settings for an acceptable exposure. Quality glass should not degrade the sharpness.
Exif = Short for Exchangeable Image File, a format that is a standard for storing interchange information in digital photography image files using JPEG compression
as far as I know it will not degrade the image but you will lose stops of light.

I strongly disagree. Whenever you add glass that magnifies you're changing the original formula.
Common sense tells me that something gonna suffer.
Here's what The Digital Photography School has to say about this topic and we're going with Canon glass, not aftermarket.
Image Degradation Extenders multiply not only the focal length but also any aberrations of the lens you pair it with. As a result youll notice on many lenses that image quality suffers Im told this is particularly the case with longer extenders (x2) where sharpness and contrast suffer particularly when shooting into light (where flare and ghosting can be a problem). Using the best quality lens possible will help keep such degradation to a minimum.
