Hi Newblood,
if you are looking at comparing the spec of various camera, you can try the following link:
http://www.dpreview.com/reviews/sidebyside.asp
However, technical spec does not usually equate the image quality that the camera can produce. Just like having a long list of expensive lens under your arsenal doesn't make you a great photographer.
In the same website dpreview.com, you can find a lot of more useful in-depth reviews and recommendations by the "forumers".
I basically started this process myself few weeks ago while I am looking for a Point and shoot camera.
And eventually I ended up with a Canon DSLR.
Just a suggestion for you with your 5k budget
1. Canon 550D body and 18-200mm~$2000
2. Nissin 866I ~$380 (if you are a purist, canon 580something... ~$680 )
3. Digital Dry cabinet 100L ~$400
4. A tripod ~$380
5. Third party Camera bag ~$30
6. Third party battery grip ~$140
7. Extra 16g SD card ~$40(this is the price someone on this forum offer. )
=====================
$3370
Still got $1630 balance of which you can buy a 80cents coffee for me and the rest you can buy lens to add a long list of mm to your signature. :bsmilie:
ok,thanks
