I'm using a Nikon D5300 with the Nikon DX AF-S Nikkor 35mm f/1.8G. My photos often look blurry or out of focus, and they also seem grainy even when the lighting looks good. I'm not sure whether the problem is the lens, focus, camera settings, or possibly the sensor. How can I test what’s causing it and troubleshoot the issue?

Let us try to discard some variables.
The usual technical stuff. Is your lens intended for your camera? Some 50mm 1.8 lenses are not for all cameras.
Do you hear the lens trying to focus?
Does using a different lens solve the problem? Let's say you never have a problem with the kit lens.
Are you focusing, for example the face and then reframing? Does the problem remain if you do not reframe? (Forget a horrible framing for the moment)
I have probably a bad news. I have a 50mm f1.8 Nikon lens that backfocus. This is the lens that simply focuses on the wrong position.
Make a testing setup.
- Put the camera on a table (or tripod)
- Put a really sharp and contrasty object, like some Lego bricks at a given distance. Let's say 1m at the center of the scene.
- Put some other bricks at 5-10cm closer and some at 5-10cm further away.
If your center brick is not sharp, but one of the others is, the lens is faulty. Some lenses can be adjusted or recalibrated.

Generated from our catalog & community — verify before relying on it.
A dirty sensor usually causes spots, not overall blur or missed focus. Your 35mm f/1.8G is compatible with the D5300, so start by isolating the cause.
Try this:
- Put the camera on a tripod or stable table.
- Photograph a sharp, high-contrast subject at a known distance.
- Place other objects slightly in front of and behind it.
- Let autofocus lock on the center target and take test shots.
If the sharpest area is consistently in front of or behind the target, the lens may be front- or back-focusing.
Also check:
- Does the lens autofocus normally and do you hear it focus?
- Does the problem happen with another lens, such as the kit lens?
- Are you focusing and then recomposing? That can shift focus, especially at f/1.8.
“Grainy” usually points to high ISO or low light, while blur points to focus error or camera shake. For testing, use good light, keep ISO low, and don’t reframe after focusing. If another lens works fine, your 35mm may need service or replacement.
