Meter response + Lens response. >> True...
Total Focusing time F = (x + y)
where x depends upon how powerful the CPU of that particular camera body is and how many AF sensors are giving input to the CPU.
and y depends upon the lens specs.

Thanks a lot for enlightening me on all these issues!!
Now I am going to the library to check the books you have told.
thanks once again!!

Boli: Yesterday evening I made 8"x10" prints of 3 pictures. All pics were shot with camera held steady on a Tripod (so no human hand-shake affeting pictures)
1. Taken with my 50mm lens
2. Taken with my 28-105mm lens set @ 50mm
3. Taken with a 28-200mm lens set @ 50mm
All pictures were shot at f8 aperture.
I found that the one's taken with 50mm lens and 28-105mm looked almost the same. Only a slight deterioration in sharpness. But the 28-200mm lens was fairly less sharper than the other two.
I then made 16" x 24" prints from the same negatives and then the picture taken with the 50mm lens was still sharp and the one take with the 28-105mm lens showed deterioration in sharpness....I did not ever bother enlarging the picture taken with the 28-200mm.
Hence, I am tempted to think that, unless one is a sharpness freak, for all practical purposes the medium range zooms such as the 28-80mm or the more recent 28-105mm, 28-120mm are good buy if you are not going to enlarge your pictures to more than 8"x10" size.
Hope this information helps.

Maverik,
That is indeed great!! So it is a trade-off between carrying more number of lenses and compromise in image sharpness.
But 50mm lens seems to be really essential, to have the best results.
As you have explained about enlarging the picture. Is the sharpness or the granularity/resolution dependant on Film Speed. This issue really confuses me.
I guess this weekend I will be (should be) a proud owner of N65 + 28-80mm f/3.3-5.6D. Later on planning to add a 50mm and a zoom lens :-)
I will report the details.

Just curiosity..

But 50mm lens seems to be really essential, to have the best results. >> Any fixed focal length lens, be it 50mm, 100mm or any other focal length will give you good results. These lenses are excellent when you have the time to think and move around to compose your pictures.
If I am travelling with ppl, I prefer to use the zooms as they provide flexibility in framing with minimal time wastage. The loss of sharpness is something i can live with in such situations. Atleast I have a picture in my hands 
Boli: "Is the sharpness or the granularity/resolution dependant on Film Speed." -> I have written an Article on Flim Choice/Selection on the BB "Tips and Tricks of Photography". Check the "Article #1" in the archives of Aug 15 under that BB. There is a section on Film Speed/Granularity in there.
In general, higher the film speed, more granular will be your pictures.
Also, the granularity becomes very pronounced when you enlarge a photograph. Example: 4"x6" photos made with ISO100 and ISO200 speed films will look the same to naked eye. Make 8"x10" print and you will see that picture made with ISO200 film will start looking granular or less sharp.
If you make a picture with a ISO800 film, even a 4"x6" print will look grainy.
Also:
The apparent sharpness of a photograph depends upon the contrast at which you print the picture. If you print a picture at a higher contrast, it will look more sharper than the same picture printed at a lower contrast. If you don't print your own pictures...never mind...
Boli: Yes, you are right, me and a friend of mine have set up and small studio (Hot lights and reflectors, nothing fancy) and a development lab in the basement of my and his houses.

Here is a picturee I had taken a while ago on a ISO 1600 film...you can see how grainy the picture is (it appears unsharp)... a result of using high Film speed...

I am planning to buy a tripod for my SLR. I am ready to spend upto $70 for it. What are the things I should look for specifically? Like Height, Mount etc. Also, if someone can suggest some model commonly available, that will be great.
Any help will be appreciated.

I evaluate tripods on the basis of
1. Ability to go as close to the ground as possible. Some tripods have a center pillar and that does not allow you to position the camera close to the ground.
1a. Ability of the tripod to let you shoot vertically down, the objects fallen on ground.
2. Maximum tripod height without extending the center pillar. Center pillar is a monopod types cantilever structure and hence not so stiff and sturdy, hence I say w/o the center pillar.
3. Stiffness of the Tripod. Mount a 300mm lens on the Tripod and tap the lens lightly while looking through the view finder. If the picture moves wildly, do not buy the tripod. In such cases the mirror vibrations will kill your picture.
4. Degrees of Freedom of the Tripod head. Should have at least three degrees of freedom, viz Roll/pitch/yaw or tilt-pan-xx (i forget the tech word for the last rotary degree of freedom) as they call motions of the camera. The Tripod head: there are numerous, Arca type, Swivel, Ball-head.......you should get a head that you find the most confortable to work with. I have the Arca type.
In a $70 budget, I have found Sanford-Davis to be a good Tripod. Fairly light weight and sturdy enuf for lenses upto 400mm.
Beware: Some Tripods are marked Video/Camera. Do not buy those as they are invariably less sturdy. My 1st Tripod was this type and it sucked. Buy only those made specifically for camera's. They are designed to be sturdy enuf to take-up the weight and vibrations.
The Best are Bogen/Gitzo but they are expensive and heavy.

Maverik, Do you use Nikon Coolscan Film scanner? Ever tried Minolta Dimage? How's your experience with either of these two?
I don't have a good quality film scanner and have to use my old and cheap flat bed scanner. In the whole bargain, loose all the quality and sharpness. That's why thinking about buying a film scanner.

Sonalin - Don't know what kind of priceline you are interested in. Couple of years ago we had bought Nikon D100. It was okay. Recently we have got Nikon D2X and so far we are loving it. We are not professional (or even good) photographers, but I think probably because of that a good equipment makes noticeable difference to us. When we got D100, it was selling for around USD 1600. We got D2X for USD 5000. With performance plan (extended comprehensive warantee) and sales tax - it easily tops USD 6000.
We stuck to Nikon because our film cameras were Nikon and so we already had a few lenses. We decided to remain within the family. As such, we never really researched other makes.

Hi Priya,
Thanks for the post.
D2X must be real good ....... Do you find huge difference compare to your D 100?
I am looking at something around USD1000 including 5 years warrantee and lens.
Right now, I carry two cameras with me, one still digital where I can upload my photos then and then and other film SLR when I wanted to take good photo. Now, I want to combine both so that I can carry only one.
I am not very good photographer but certainly find difference when I take photo using still and SLR.
So I am after a smaller digital SLR that I can carry everywhere and with medium price range.
I was short listing Canon 350 D (, 8 mega pixel, 18-55 mm lens) and Nikon D 70 (6 mega pixel , 18-70 mm) they both are of similar price.
This is where I found some reviews.
