After reading a few threads, I think I should start with two things:
1) you guys are fantastic and it looks like everyone is really helpful, so thank you in advance for your guidance. 2) I have a decent understanding of shooting techniques, exposure, etc, but I am by no means a pro, so heavy technical jargon may go over my head at this point.
Years ago I had an N60. Loved it. I jumped into digital eventually with a D50. Loved that too. Three years ago, my daughter was born and I wanted a "better" camera. I thought the 3100 would be good because it was relatively inexpensive and had video. I have yet to get it to take as nice of photos as my D50. I can set the cameras exactly the same and the 50 blows away the 3100 every time. No clue why.
My main issue is that they are always at least slightly blurry. Any ideas why this happens? Thanks again!
If you are using one of the 18-55mm f/3.5-5.6G AF-S DX (VR) kit lenses disregard the next question.
What lens or lenses are you using? Please provide full discription.
The reason that I ask is that the D50 has an AF motor built into the camera body that supports AF with older AF and AF-D (screwdriver) lenses as well as AF-S type lenses. The D3100 does not. It only supports AF with AF-S lenses that have an AF motor built into the lens. In other words the D50 supports AF with lenses that won't AF on a D3100.
Please post images so we can see the problem, without images we are just guessing. To give you an accurate,informative and correct answer, we do need to have an example so we can read the exit data of the images.
I am assuming you are pixel peeping (max resolution) viewing of the photos on your computer. So bear in mind the D5100 has a lot more pixels that the D50. So your lense might still be the problem. The D50 does not test the quality of a lens at all. But the D5100 would need a reasonably good lens to be sharp at the pixel level. So what lens are you using?
