i have a 7d, a 24mm and a 100mm.
what i like in the nikon side is that spot metering is tied to which ever af point you are using, i think canon also offers this featured but only on the 1d line.
i like it that the d300s has 51 af points. even though all 19 points on the 7d are cross type, i've read that the ones on the d300s is just as quick and just as accurate, i cant say for sure though.
i like how nikon's battery grip has its own joystick or controller so choosing af points while holding the camera in portrait orientation isn't very difficult, i'm having a hard time reaching the main dial at the back of the 7d when griped.
also, some nikon lenses can be used on m4/3 without losing aperture control. my dslr and m4/3 camera can share lenses.
canon is great, but i guess i'm a little curious, and would like to try nikon. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='

my reasons might be petty, but if i can find a good deal for my canon then why not?
i have thought about going full frame before, but i hear that af on the 5ds aren't very reliable...i guess if i'm going nikon i can get a d700 and start with a 35mm and slowly build my set up from their.
still, i'm curious about the focus shift on nikon primes and would like to hear from those who have experienced this. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />

The G lenses (all 3) will lose you the aperture control on micro 4/3rds... The lenses I mentioned concerning the full frame option (with much cheaper lenses doing the same) all have an aperture control ring (35mm f2, 85mm f1.8, 135mm f2 DC).
Concerning cross type sensors or not, cross type is not per definition more quick or accurate. It is just that with line sensors, it can happen that a texture which shows detail/edges in a certain diraction may not be detected (does not happen often, but it can happen). A cross type sensor avoids that in those cases.
The AF speed has nothing to do with the type of AF point, has more to do with the camera's AF module (the computing power of it) and the lens mounted. The 85mm f1.4 and 50mm f1.4 AF-S lenses you list are no speed demons. The 24mm f1.4 is speedy enough to be called "fast". The lenses I listed as alternatives on FF are all screw driven, fast enough for what they are designed for but no speed demons either.
So.. AF speed wise, you won't go a step forward. Generally the 7D is a tad faster in acquiring focus, but a lot depends on the lens mounted. Anyway, the lens types you list are not really designed for tasks where AF speed is a real issue, either. Only the Canon 85mm f1.8 USM is often used for indoor sports shooting, because it has such lightning fast AF.
And it is fine if your reasons are petty. They are your reasons.
