You have the AE1 squeak? Normal in these cameras, in fact most of the A-series of camera. You will find your shutter speeds slowly becoming less accurate and the risk of jamming becomes more evident. Most repairers recommend replacing the shutter at $150; I have had 3 do this over the years and use the camera till it becomes too annoying. Given the low price of these models, it is not worth repairing in my opinion. I just altered my ISO setting to offset the delay. Best way to avoid this, wind and shoot several times a month to ensure lubrication of the shutter.
