As usual, your support is great TCav!

reading my question again, I didn't express correctly what my doubt was.

D7100 is capable of using both CDAF and PDAF???

I stiil have in mind how cheap I felt a D5100 with the 18-55 kit lens (I posted it was a D3200 but that was wrong!)...
And I suppose the D7100 should feel better...

DSLRs are not good for making home movies and have way too many drawbacks. If you want a camera for that get a mid range to high end compact like a panasonic or sony.

Krichton, thanks for you reply!

As mentioned above, video will not be the main purpose for the camera I'm searching for.
But it is a big issue, since my wife usually shots lots of videos...but I mainly shot stills.

The D7100 uses PDAF for stills and CDAF for movies.

CDAF can only be used when the image is projected onto the main image sensor. When shooting stills, a mirror that projects an image up to the optical viewfinder, blocks the view of the image sensor, so CDAF can't be used.

PDAF can only be used when a mirror projects an image down to the PDAF sensors in the base of the camera body. When shooting movies, the mirrors are out of the way so the image is projected onto the image sensor, so PDAF can't be used.

Now I get it!

Thanks again!

Now that Nikon has replaced the D5100 with the new D5200, they have really dropped the price of the D5100. You may want to consider the Nikon D5100, it's still a fantastic DSLR. The money you would save could go for better lenses. I agree that the Nikon's still image quality is better than that of the Canon, however I think the Canon has a slight edge in video.

The compacts are great for quick video clips. The DSLR video are better but require allot more work and skill to take advantage of the system. Movie making is allot of work and requires skill in editing.

During last 4 days I have play around with a Nikon D5100 + 18-55 kit lens...
I got some very good shots...but I found something I'm not 100% sure about...
Always shooting with AF, I got at least 10% of shots out of focus...

Because of the larger image sensor and the correspondingly more shallow Depth of Field, focus is much more critical when using a dSLR than a P&S, and some people making the switch take longer to get used to it than others. I'm certain that the 10% out-of-focus shots you got are a result of that. The D5100 has a fast, accurate AF system that might be responding to circumstances you didn't intend and might not have even been aware of.

I suggest you familiarize yourself with the AF section of the manual, choose the settings that you think would best suit your style, and give it another try.
