I have a dilemma and was curious to hear what others think. I found myself with 2 cameras, different systems and different lenses. I need to choose one and get rid of the other as I have decided to invest into one system only. Camera 1. D7000 with 18-105 kit, plus 35mm f/1.8G dx lens. Needless to say that this camera is a phenomenal system. Fast and accurate autofocus, excellent video quality, etc. You're all familiar with the specs by now. The only negative really is the buffer speed for burst shooting, (60D is actually more capable even with the slower burst rate) and occasional over exposure with bright light. No big deal, that's what Exposure Compensation is for. I am not thrilled with the 18-105 kit lens. If I stay with the D7000, the kit lens will be sold and I will purchase the 17-55 f/2.8G. The D7000 has very clean images at high ISO's. Camera 2. Canon 40D with EFS 17-55 f/2.8 IS USM The 40D isn't as advanced as the D7000 but it is a tried and true camera. It takes great photos, not the best autofocus system, but very adequate, and it doesn't take video. The EFS 17-55 f/2.8 is arguably the best piece of glass you can put on a cropped sensor DSLR. The fact that I own one really makes my decision a difficult one. Canon has a better and more affordable line-up of quality lenses that Nikon. Other factors include the fact that I have Photoshop CS4 and it doesn't work with the D7000 unless I first convert to .dng format. Thats a pain in the butt, but not a deal breaker. 40D is old enough that everything works with it. So, I am not sure. I have Aperture, and it works with both systems, but image quality is important for me, so working with Photoshop and some of the proprietary software is also a factor. The bottom line is I have to get rid of one. I would definitely appreciate other opinions. Pros and cons of both. I love both cameras. The D7000 is amazing, but the EFS 17-55 lens is awesome to shoot with. Thanks for your input.
