Note also that the old rule of thumb that a shutter speed of 1/30 second is fast enough for a sharp picture is not good enough in the digital age. In the analogue era you would not typically zoom a picture to see very small details, so a picture would look sharp and that was it. Today, we take one picture and zoom in expecting to see small details clearly ...

Use a tripod. Shutter shake is a very frustrating aspect of modern cameras. When I had my old Fujica 801 I could shoot at 1/60th of a second and take a sharp photo. I would not trust myself below 1/250th on my Fujifilm Finepic. Try shooting on a clear day - you will have more light and less problems to solve

I firmly believe you have more use of thorough knowledge about sharpening techniques than staring too blindly on the technical side of the camera. The idea behind the statement: I'd expect the down sampling to generate more blur than the anti aliasing filter ever did. The tool you have to recover the blur is just sharpening.

I'd be surprised if you saw a difference. Remember, the image has to go through a re-sizing algorithm that would cause the slight difference between an AA image and non-AA image to disappear.

The effect of omitting the low pass filter decreases as resolution increases. That's why we're suddenly seeing AA filterless cameras, we've reached a point where aliasing is no longer a significant problem. The difference you see will depend on what glass you're using, really sharp lenses will still produce aliasing, at least in the centre. In most cases ...

I see no problem in either of these images. They both appear correct. Lenses are not 100% sharp to begin with and on cheaper lenses it is not atypical for the resolution of the camera to outpace the resolution of the lens, particularly on entry level and kit lenses like the two you are using. This is even further compounded by using high aperture on a ...
