This sounds like one of those cases where you think you can put a camera in Manual mode and put any numbers you want into it and expect a properly exposed photo. NO. Shutter speed, aperture, and ISO all have to “balance” for a proper exposure. Use a semi auto mode such as Av or Tv. One thing though, I have never heard of a “Kalimar” lens. If it is not a lens, (and by the way, the word is LENS, not “lense”), that is dedicated to function with all Canon exposure functions, then yes, you may HAVE to use the camera in Manual mode. Again though, you have to learn how to set the parameters correctly for a proper exposure.
What to do about it? Read your owner’s manual on how to adjust the camera properly. Your camera has an exposure index scale which usually looks something like this: -3,,-2,,-1,,0,,1,,2,,3. They’ll be a small dot that moves from -3 to +3 depending upon the reflectance value of the metered area along with the manual settings that you have chosen. If you had looked at the scale while taking the photo, you would’ve seen the dot on the +3 side of the scale which would’ve told you that the image was going to be overexposed.
When in manual mode with this specific lens, you can only control the shutter speed since the lens does not appear to have an adjustable aperture. Because of this, your only method of controlling the exposure is via the shutter speed and ISO settings. If you want to use a fast shutter speed, you will need to increase your ISO since the aperture is fixed. If you want to use a slower shutter speed, you’ll need to decrease the ISO. However, if your ISO is set too high while taking photos on a bright sunny day, you could run into a situation where the camera cannot choose a shutter speed that is fast enough to prevent overexposing the scene. But again, even if this were to be the case, your camera clearly shows you in the viewfinder and on the back of the camera that the image is going to be overexposed by placing that free-flowing dot on the +3 side. In fact, it was probably blinking which indicates that the actual amount of overexposure exceeds +3 stops.
