Hi guys,

I know its brand and model comparison thread again, but I really want to get some experts' advice.

I have used A550, D90 and 550D before and I know each of them has their own pros and cons.

Now I am DSLR-less and wanting to get back into action with some semi-pro stuff.

Had targetted these 4 contenders:

1) Nikon D7000
2) Pentax K5
3) Canon 7D
4) Sony A580

I will be primarily using 3-4 lenses for my needs.

- 35mm F1.8 or Sigma 30/1.4
- Tamron/Sigma/Canon/Pentax 17-50 F2.8
- 18-200/250mm
- 55-200 or 70-300mm

Other than body selection, I know I will probably spent the least amount of money by going the Sony route, however, I would prefer the 3 other metal bodies actually as A700's replacement seems nowhere in sight at least for the next 6 months.

appreciate your inputs. My budget around $3500-4000. Primarily using to take pictures/videos of my kids outdoors and indoors, so AF speed and accuracy is quite important to me.

Thank you folks!!!
:)

Get the K5... read that its a very good DSLR.. the a580 still remains as the mid-level and not semi-pro yet though.

The K5 is a very good camera for the money, but it does not AF in video mode.

Very close image quality between D7K and A580 based off the imaging resource site.
http://www.imaging-resource.com/IMCOMP/COMPS01.HTM
K5 is not directly comparable atm since the site does not have sample images from it. It current claim to fame is its reported 14 stop dynamic range and high overall score on DXOMark

Since you are choosing 3rd party lenses, there isn't too much any of them will offer too differently in this respect.

Really no wrong whichever camera you choose. Just needs to meet your budget and needs.

Just curious, are these lenses you intending to get or already own one?

For AF speed and accuracy while taking videos, you should probably look at the Sony A33/A55.

The D7000, using the A55 sensor, should also have some improvements in video AF. But it will not be as fast as the Sony SLT series.

I think 7D has the edge in terms of AF speed and accuracy. Cross type for all the 19 points. Canon video is very awesome too.
Coupled with Canon 17-55 USM, AF should be very quick. Not sure bout the other lenses though.

Yes, D7000 has AF in video but it's hit or miss kind of AF system especially for fast object. As for the 39 AF systems, there are only 9 cross types, but the numerous AF points should be useful for tracking moving kids. Coupled with Nikon 17-55 will be awesome, the focusing speed of 17-55 is very quick.

Not in video. And for normal pics, the other cameras are very quick and accurate too.

D7000. It is top of your list.
Yup. Same sensor as A55/A580/K5 and decent build and specs. If build quality is less important and you want lightweight and fast Autofocus in video and live view with an articulate LCD, A55.

lol TS only listed four options.

i would go for 7D for its AF accuracy. as for video, i think the Sony would come out well.
Is there confirmation of this supposed AF accuracy and speed over the other options?

how about the G12 or S95 which are small enough to carry everywhere and have AF in video. If you dont mind non-HD video then the EX-1 with f/1.8 lens could be a good choice for indoors.

Not exactly the recommendations you wanted but another set of choices for what you want to do.

I think video slr is still in its teething stage but give it time if you really need such a feature.

Did you check the DXOMARK sensor rating??

Canon 7D performed badly relative to its peers. 5 years back Canon sensor was the best and because of it, they gained market share because of their proprietary sensor.

now Sony has developed a sensor with a whopping 2 more stops of dynamic range, better high ISO performance, more color depth, I am wondering if canon will still stick with their inferior proprietary sensor when EVERYBODY else is using sony's.
