There has been a lot of talk on the internet from folks considering the switch from Canon to Nikon. Some of them are ex-Nikon shooters looking to come home, and some are Canon shooters intrigued by everything the new Nikon D3 has to offer.
Considering I used to shoot Nikon (switched to Canon in the Spring of 2006), obviously these new Nikons hold an appeal for me. I like my Canon's, and although I've never had any problems with them (touch wood), I don't have the same confidence in
Case in point: the 30D vs the D200. Image quality aside, when you pick them both up, the 30D feels like a toy in comparison. The D200 is much better built and is much better stacked feature and ergonomic-wise.
That said, there is something missing in Nikon's lens line-up that may stop me from buying a D3 or a D300 (I wouldn’t switch back, but would shoot “bi” if I bought a new Nikon). They have no standard zoom with VR. Big problem! I was really surprised when they announced the 24-70 with no VR. What were they thinking? This would've been a huge thing for Canon and Nikon shooters alike.
Image stabilization (or VR or OS or whatever you want to call it) is something that should be pretty standard now. I like the idea of a body based system like the Pentax K10D or the new Sony A700, but so far these haven't panned out. The K10D doesn't even have pro lenses available yet, and the AF speed is an issue (maybe not once we can get a hold of the new Pentax lenses). The Sony A700 looks good on paper, but it's IS better be better than it's A100 little brother because the A100 wasn't all that. Also, A700 images I’ve seen so far look pretty bad at high ISO.
Then there’s the price. While this isn’t a consideration for some, it is for me. I like to get maximum value and a great bargain. As much as the D3 appeals to me on many levels, it's price tag does not. The D300 is more my speed. I'm not saying the D3's price isn't justified, just that it doesn't fit into my business model. So, the big question is how the D300 will do on image quality.
And of course, Nikon has yet to introduce a standard zoom with VR. Will they? This is something many will want to think about before considering a switch. With Canon you’ve got the Canon 17-55 f2.8 IS and the Canon 24-105 f4L IS to choose from. With Nikon, you’ve got nothing in a PRO caliber.
And what if Pentax brings out a successor to the K10D that uses the new 12MP CMOS sensor that the D300 and A700 use? The K10D is one FULLY FEATURED camera! If the new lenses deliver good AF speed, I think I'll be adding a Pentax... not a Nikon.
Ahhh... so much to consider!
