On the left side of the lens barrel, there's a small switch with two positions, marked AF and MF. 1. Before you jump to buying a new camera, go through this quick checklist with us to see if your blurry backup camera has a quick fix. The camera’s lens could be dirty. One of the simplest and most common reasons for a blurry image is a dirty lens or water droplets on the lens. This is the first time I've used the video feature on my 5D II so maybe I've missed something. For instance, if you are zoomed to 100mm, your shutter speed should be 1/100th of a second or faster to avoid camera shake. First thing I do with a blurry image is to clean the lens and check the video. If you’ve got a blurry backup camera, it might just have some rain, mud, or other type of grime on the lens. Every single picture I take with this lens is blurry. I can't figure out why my video's are blurry. Condensation is because of 2 factors, humidity and temperature difference between the air and the camera. How fast your shutter speed needs to be depends on how steady you can hold your camera. For details on the setting screen that appears on your camera or the [Shooting Modes] in which the [ISO Speed] can be set, see the table at the end of the page. For example in summer there may be condensation in the morning on the outside of the camera lens. Attach the camera to a tripod. Make sure the switch is set to AF. I have been adjusting the viewfinder without the lens so the focus points are clear and sharp,and I see them clear without the lens, but when the lens is on and wide angle the blurry is there again.. I have a canon xsi that takes lovely, crisp pics with the EFS 18-55 IS lens and a EF 50 1:1.4. It happens all of the time and at all apertures. I tested two other lenses and they do not show this problem. Additionally, you should set the [IS Mode] to [Off] when shooting with a tripod. I'm trying to shoot jewerly but it looks terrible. Make sure your shutter speed is faster than the equivalent of your focal length. Check the Exterior of the Lens. My 50MM 1.8 seemed equally sharp on both sides with a little fall off on the edges which I would expect. Note that when the switch is set to AF, normally speaking the camera refuses to take a photo if it can't... - Canon … I purchased Canon zoom EFS 55-250 1:4-5.6 IS. I did use a flat surface and the camera was square to it on a tripod. If your camera moves, even a little, as you press the shutter button your picture might turn out blurry. A fixed lens camera that is out of focus must be replaced. When condensation forms on a security camera, it can blur lenses and compromise image quality. The weight of your camera and lens can influence this. I also tested the 18-55 MM IS. I recently purchased a used Canon 55-250mm IS lens and it works nicely at 55mm(even with lower shutter speed, and f/4 aperture), but turns out quite blurry at longer focal lengths, even with a shutter speed of 1/800, f/11 and while mounted on a tripod. If the shutter speed is too slow, the camera picks up that movement, and it looks like a blurry photo. Condensation occurs on the warm side of the glass. I wanted a zoom to take pictures of sporting events like soccer, baseball, and horseback riding. This first one is pretty easy. This is commonly called ‘camera shake’. Check the following: (1) Autofocus might be switched off. Exactly this happen with my 60D... And only happen when wide focals are used, but If I'm using long focal everything is very sharp and clear. 2. Cameras that are installed outside will get dirty and wet.
