OOPS that was supposed to be 300 2.8. Anyway, the TC's really suck up lots of light. If the 1.4 fits the lens you want to use it on Nikon / Nikon than try it. But I have rarely been happy with the results (Canon) of a 2x on a zoom. However the 1.4 works great on my 70-200 2.8L and of course on the 400 2.8 L. If you are trying to just get to 300mm then the best answer is a fixed 300. I am not well versed in Nikon stuff but the do have a good 300 mm f4 D, just a thought... -----Original Message----- Foto/SFX, San Jose, CA 408-835-1184 http://www.aviationphotographers.org/, http://www.fencecheck.com http://www.myspace.com/fotosfx, http://www.portfolios.com/profile.ht...=14627.baldwin |
