Could someone help me understand the technical bits about focussing :bang:

Thought Id settled on teh 60d after the 550d, but now I notice the D7000 might be within budget so thats now an option :thinking:

Just wanted a little advice on the autofocus systems, what real world differences does it make, other than just numbers in the specs. So what does this mean in english :P

Nikon D7000

• 39 AF points
• 9 cross-type sensors

Canon 60D

• 9 cross-type AF points (f/2.8 at center)
• Center point additionally sensitive with lenses of F2.8 or faster
• AF working range: -0.5 - 18 EV (at 23°C, ISO 100)

Im go to a few local rallies so would like to be able to get some decent shots, and some of the off road events I attend. And also just a general all round holiday, family etc. etc.

Thanks for any advice :)

Cross-type AF / sensor means it detects contrast in both horizontal and vertical direction.

f/2.8 sensitivity means that the centre AF point is more sensitive / accurate on f/2.8 or faster.
 
they kinda act as assist points the main autofocus areas, so things like birds in flight or motorbikes the camera can predict focus in continuous focusing mode better, technically the camera will be quicker at focus locking with 1 point.

I would look at both the D7000 & 60D as alrounder cameras and will do pretty much anything you throw at em.

What lenses do you own? It depends, if your investment in Canon gear is minimal, D7000 will deliver more goodies.

60D has slightly tweaked AF system that goes back as far as 20D in 2004. It is not the best AF system for action.

D7000 on the other hand has far more advanced AF, similar to D300 and perfectly suitable for sports. ISO performance also seems to be better. Oh and it has robust build quality, while Canon decided to go for cheap plastic option with 60d
 
I have nothing at the moment :D

My first step up from point and shoot. This is why it's such a hard decision as I know once I've decided, it'll be the brand I stick with.

I haven't had a play with the d7000 yet, but I have had a play with a 60D, and tbh it doesnt feel plasticy, it does have a nice solid feel to it, and just from looks seems nicer than the d7000 which seems to have a huuuge amount of buttons everywhere.
 
Nikon tends to get a good press for their AF systems, it's only really with the 7D have canon addressed this and come up with a real competitor. Shame that Canon chose to pinch the AF system for the 60D from the 50D rather than from the 7D. Personnally I went for the 7D, but then I already had a collection of Canon lenses from my 40D.

If you've no brand loyalties or collection of lenses, then other than at the top end of the range than the Nikon's AF systems then to be the winners. Not that there's not lots of other reasons to be considering Canon....

Those buttons tend to make it easier to make changes to certain settings, rather than having to go through sub menus on the display.

Having said that you should try them both and buy the one that feels best in your hands, with the most intuitive layout.
