Strange pixel effect on all photos

[DistantMelody]

Hello everyone

I have a Sony SLT-A77V camera. I nearly always use a tripod and a remote control for added steadiness. I have a polarizer for the nice deep blue sky effect. I can always see a pixel effect on my photos. Here is one as an example:

It is rather upsetting when I do my best and get these results. What could be the reason?

I wanted to go into Stock photography but it turns out they are quite particular about this sort of thing and my images wouldn't be acceptable due to the pixel effect.

Please help me to fix this problem.

Hello James

Automatic would be best for me because I couldn't work the ones I have at all. Which ones are the best in your opinion (without considering price)?
