Agreed with what Chris suggested. The lens hood must sit in properly at fully locked position. Need to use Canon orginal hood; other brand might pose a problem. Please bear in mind that a dark shadow will still appear at the bottom center if using build-in flash when shooting at 17mm; which is normal. When using 17mm, always use external flash or remove the lens hood when using build-in flash.

This is called "vignetting". To me it sounds like your lens hood isn't mounted correctly. If you don't turn it on all the way, exactly this will happen, because the longer "leaves" on the hood shadows the edges of the frame.
So, try to turnt the hood all the way on. You might have to use a little bit of force, as the hoods can be hard to turn sometimes.
Hope this helps!

Front and back focus tests are good to run. You need to do it for each prime lens (fixed focal length) you have, and at your favorite focal lengths for wide angle zoom lenses too. That means on this 17-50, you would pick wide 17mm and zoomed in 50mm, and several others between. If you pick 25mm and 35mm to test, you would end up with 4 potentially different adjustments. These would apply only at 17, 25, 35 & 50mm. If you shoot at say 20mm focal length, and assume it's the same as 17 or even 25mm, you may be wrong. Too much back or forward focusing is a problem with the camera body usually - not the lens.

I'd pay attention to the lens. Look for cloudiness on the edges of the glass, scratches and fungus on glass, wetness or oil on the aperture blades, specs of dust inside the lens, etc. All of these things take away value from the lens, as they can adversely affect the image or shorten the useful life of the lens. You check these things by looking directly through the lens (not on the camera) and look at a dark background - then a light colored background to help show dirt and dust inside.

The only other thing is to look at actual images taken with the lens. Enlarge the pictures to 100% or more. Look for fuzzy edges, purple fringe edges, colors. You will see all of these issues the more you zoom in. You have to decide what it acceptable to you and what is not. Expensive lenses capture great color, are very sharp and have minimal purple fringing on hard edges (high contrast areas) in pictures.

Good luck!

Sounds like your image stabilizer got damaged by the fall. You'll have to get your camera serviced by an authorized Nikon service center.

Lens will not change aperture setting.. it's stuck on F4. Should be able to change to F2.8 Michael


You'll notice that the maximum aperture is specified as f/2.8-4.0. The lens has a maximum aperture of f/2.8 only at the 17mm focal length. At the 35mm focal length, the maximum aperture is f/4.

Does the lens open up to f/2.8 when you zoom out to 17mm?

Shadow on image yet nothing in front of camera. It is in the middle at the bottom edge of the image. It only appears when I set the lens so that it is all the way in at 17. I have a canon ef-s 17-55 f2.8...


Most likely it is dirt/dust on inside the lens. If it is in the bottom of the picture, the dirt will be on the top edge of the lens. If it is inside the lens, you will probably not be able to clean it your selves.

Focus hutning with Canon EF-S 17-85mm f/4-5.6 Image Stabilized


I had this problem too, then my camera started getting Error 99 (there is some problem) and not working.
If you look at this website and follow the steps under Update 2

I think you will fix your problem. The connections between lens and camera probably have a little dust in them, use a soft rubber eraser to clean them. Make sure no dust or pieces fall into the camera or lens when cleaning!

Uneven flash


Look carefully at your images taken with flash... on the horizontal image is the lower part of the image slighty darker and have a rounded fall off at the edges? Is the vertical image dark side a straight hard line or is there a rounding to the top and bottom?

What we are looking at is if you have a very wide angle lens with the lens shade attached to the lens, then the built-in flash catches part of the lens shade and make a shadow on your subject... take the lens shade off and try the same shot and see if that makes a difference...

Have a great day...

Image reduced by dark edges


An adapter tube has to flare out at the end or it will cut the corners off at the wide angle setting. Telephoto should be ok though.
