At which aperture is it stuck? Have you tried adjusting directly from the aperture ring on the lens?

Lens problem


hello,your particular problem sounds,back to front,are you sure your camera is working perfectly? are you able to meter manually?is it an all auto exposure/auto everything?because by design an aperture of say F4.5 is pretty much wide open to allow maximum light in,so depending on what shutter speed you select(if your able to,manual settings on camera?) so as you progress through the F stops,the higher the number,the smaller the aperture,so henceforth you are letting in smaller amount of light in,because from 1 setting to the next,you either halve or double the amount of light that enters the lens.do have a close look through the front element of the lens to see if the aperture is actually corresponding to what your settings are on the camera.hope that helps,cheers.

My canon fd 50mm 1.8 lens will only focus close up...I can't bring anything further than 6 or 8 inches away into focus


Check to see what focus mode you have selected. If it is on manual focus MF then use the narrow ring at the very end of the lens to make adjustments.

Focus out problem in canon 50d while using 24-70mm lens?


If by a "normal" lens, you mean a 35mm or 50mm fixed focal length - often called "prime" lens, that is to be expected. The additional and internal rotating optical elements all contribute to loss of clarity, color loss, and increased chromatic aberration that starts to become noticeable when compared to use of a prime lens. It's a trade off; less number of lenses to carry and lower cost when using wide angle zoom lenses as opposed to a prime lens for even just a few of the focal lengths offered by the wide angle zoom types.

You can minimize the unwanted effects by staying away from both the extreme wide angle and zoom focal lengths as well as the widest aperture settings. If you can stay 2 or 3 stops smaller from wide open, you can limit these destractions from your pictures. This is recommended advice for nearly every lens: Keep away from the extremes.

Good luck!

Aperature ring


Hi, Is the aperture in max or min ?
Remove the lens. Try pushing the stop down lever and look through the lens if the aperture changes.
Look at this pic if you wonder what stop down lever means. http://www.mir.com.my/rb/photography/hardwares/nikonfmount/20AI-S2_8rearconv.JPG

AF 70-300 causes error 99 in my Canon 300D


This is usually a torn flexible circuit or binding aperture in the lens. It'll have to go to a repair shop for replacement. About a $80 job.
