My gear issues

[Katown]

Hello, I'm new to this forum.   I use a Nikon D5100 and a Sigma 150-500 lens. I just returned from a photo trip to Sudbury only to find my pictures, grainy and not the normal quality I am use to. I live out in the country and do not have internet, my mobile I do, but not a computer connection so my camera has had no firm where update,ever, could that be a factor? I used a variety of settings to compare my usual quality, which is normally crisp and clear, still grainy,  it never changed. It does not matter if I zoomed in or not. Few days before I left i was photographing my back yard birds and they were not grainy.
Any ideas ?
Thank you
Katherine.

What mode were you shooting in? Aperature priority (A)? Or one of the Scene modes? Auto?

Usually graininess is too high an ISO. If you were shooting in A did you accidentally thumb dial up to a higher ISO?

hopefully it's not something major!

I was trying (A) for the first time. I was happy about the lighting, just grainy. I also played with the ISO settings too, no difference on the lower settings compared to a higher settings. I've used this combo camera and lens for a few years, I have never had this issue before. I was going to send it off to get cleaned, see if that helps?

Not sure cleaning with make a difference, try shooting in P mode and let the camera pick the settings. Look at your images and see what they look like. Mind you I only shoot in P mode with my D7200 & 80-400 VR lense, but its worth a try to find out if it is your equipment or a setting or 2 that are off.

Thank you I'll try that and see.
