    could I use two 2x teleconverters to multiply the focal length of my lens 4x?

    And is the Nikon Tc-20E 2x Teleconverter compatible with all of the following lenses?:

    Nikon 50mm f/1.8D AF

    105mm Micro-Nikkor f/2.8 ED-IF AF-S VR

    Sigma Zoom Super Wide Angle 12-24mm f/4.5-5.6 EX Aspherical DG HSM

    Nikon Zoom Telephoto AF VR Zoom Nikkor 70-200mm f/2.8G-AFS ED-IF (VR)

    (I plan on purchasing these lenses in the next couple of years, along with a used F100 or a New D700)

    you can use two if you want, but a single 2*teleconverter gives almost any lens (barring a pro range telephoto prime like a 300mm f2.8) a big image quality kick! There are some (very very few) lenses that can take two 2*teleconverters, but its not the norm and such a combo is tricky to use well *you lose 4 stops of light*

    Teleconverters generally don't work with any lens under 100mm focal length due to the construction. Your 70-200mm should be able to take one 2*Telconverter, but image qulaity will be subpar - it could take a 1.4 very well though (and a 1.7 as well since your nikon). As for the macro I belive it can take TCs and I would expect it to be able to take a signle 2*TC without too much trouble (makes for great macro since a TC also increases magnification factors so thats 2:1 macro!)

    edit - to give you an idea here are some shots taken with my canon 70-200mm f2.8 IS lens and a single 2*teleconverter with flash support:

    thank you thank you!

    I currently have 1 for my manual focus lenses (body is the Nikon FM10) And didnt notice a quality difference, but then again I only used it twice, both times in a gym, and the pictures were all grainy (due to poor lighting and 800 speed film)....so the quality difference couldnt be noticed easily....

    Since I plan on getting an autofocus body and lenses, and autofocus teleconverter was just something I thought would be handy dandy. I am aware of the loss in light...for film, I just used higher asa film.

    I didnt even think of the 2:1 on the macro, EVEN BETTER!

    Thanks for the pictures using the 70-200 and teleconverter.

    I though of the teleconverter for shooting high school football with the 70-200 f/2.8 and just raising the ISO.
    Would A different lens be a better choice for shooting football games? (I can get front row with no problem)

    A 70-200mm should take a 1.4 teleconverter well with little image degradation and you only lose one stop of light - taking you to an f4 lens.
    Idealy a 300mm f2.8 is what you would need (but that lens costs serious money!) A 300mm f4 might be worth looking at - a respectable lens from nikon or canon and can make a decent 420mm f5.6 with a 1.4 teleconverter (though that is fore for birds outside)

    2:1 macro is fun - tricky since the plane of focus and depth of field are even smaller - but its fun :)

    is there any good zoom lenses? Something with a rather wide so i can get a couple of people in the shot to something where I can get just one person or part of one person?

    Money isnt a huge problem. I have a job and plan on saving my money for a year or two. (i get a couple thousand a year.....it minimum wage) I have it planned out--everything I want will cost around 8000 dollars (thank god im a kid and dont have other things to pay)
    the 70-200mm f/2.8 is around 1800 dollars--and id be willing to spend another thousand dolalrs---id rather not...but i wouldnt mind if i had to.

    try getting the sigma 10-20mm. Its a great lens. As for the 70-200 look on craiglist. I founf one for $1500 and the only bad thing was that the hood was scratched up which doesn't bother me.

    From a 70-200mm f2.8 IS canon with a canon and sigma 2*teleconverters added :) 800mm!

    As for good zoom lenses I think nikon have a good 70-200mm f2.8 VR (or is it 80-200mm?) and after that on the telephoto side I would stick to primes if you can. Though the Nikon 200-400mm VR is a very good zoom from what I have heard!

    I've been planning for some time to stack two 2X converters onto my 400mm. I had been looking for a forward mounting one but the only one I was finding was not the right diameter and I don't want to munkey around with adapters to make it fit, so a couple days ago I settled with another rear mount and ordered it the other day and it should be ariving in the next few days. Considering my lens I don't have high hopes for this as it's going to endup being 1600 f/22 wide open or something like that but, it'll be fun to try.

    I have a 400 f/3.5 and both a TC-14b (1.4X) and a TC-301 (2X) converter. Both are matched to the lens and very sharp. Either one individually is so sharp with that lens it's very difficult for even the experienced eye to tell it's in use. Together, well let's just say my blind granny can tell the difference, in braille. Add to the inherent quality loss the fact you now shoot with a 1120mm f/10 in full frame and 1680mm in DX crop and the best tripod is not rigid enough. A mild breeze moves the framing in the viewfinder. Unless you are a private detective and want to document a gnats behind from 1000 meters at high noon, at the equator, on the first day of spring, it's simply not a good idea.

    I'm working with a 400 5.6 on full frame and that right there is the reason I spent so long trying to find a forward mount TC that would not cut away f/stops from the lens. Never the less the fun things in life are seldom a good idea.
