Hello Patricio, I am a owner of a F601, and I have been using it for about 10 years, with *any* problem until now. Ok, I am not that kind of person that takes 10 rolls/day, but I can assure you it is a very good camera, that deserves the brand Nikon. The camera is very reliable and easy to use. But it suffers from some drawbacks, let me comment the ones you have pointed: - - I don't have any old MF lenses As far as I remember the F601 is not better than the F70 when working with old AIS lenses. The only AF Nikon that really works amazingly with MF lenses is the F4. - - I can live with no continuous shooting Actually 2 fps is *very* slow also. Don't expect the F601 to be useful for sports shots. - - Have read some comments about the N6006 being very power hungry I would say that all AF cameras are very power hungry, not only the 601. BUT the 601 uses only the very expensive lithium battery (CR P2 I think), and if you are using very bulky glasses like the AF-80-200 2.8D, autofocus and use the pop up flash all the time, you will eat one lithium battery each 3 rolls of 36 exposures. It really depends on how you use your camera. Remember that the pop up flash uses the camera's battery as its power source. - - Also read some contradictory comments about spot metering: some say it's great, some that they never use it The spot metering is one of the most important features if you want to improve your photography. And the F601's spot metering is very good. The F70 is a very good camera, and I think its main benefits over the F601 is the ability to use 3D Matrix Fill Flash and drive AF-S lenses. I personally invested in lenses, following the advices I got in this list, and I'm really happy with my decision. If I were to upgrade for another camera it would be the F90x or the F100. If you have any other doubt, just write me. nelson kao
