<p>Hi, yes it was 'Loctite Super Glue', which is a fast acting cyanoacrylate based glue (other brands are available). I used the standard - fairly runny - glue, not the 'gel' variety, just four very small spots. Regards Roland</p>

<p>It's still working...</p>

<p>I had a cross threaded B+W filter on my Canon 28-70mm lens, which I was really quite reluctant to break. So after trying industrial levels of sheer brute force, a rubber grib and selective refrigeration and failing - I used an approach that I didn't see when trawling the internet for a possible solution. In my case, the lens was cross threaded leaving a small gap between the filter and the lens. I decided to try the following approach - I ran a hard tipped felt tip pen ('Berol Handwriting') round and round between the filter and lens with a reasonable amount of pressure until I managed to pop the filter back across the lens threads and back into line. I was then able to twist it off as usual. Hope this helps someone else.</p>

<p>Well my most expensive lens is still a non L series 70-300mm DO. However, it was also one of my first. Some time after this, I picked up the 'plastic fantastic' 50mm f1.8 prime lens and got hooked on prime lenses. As a direct result of this I went on to buy two of the cheaper and some would say best value L lenses, the new 100mm L macro and the 200mm f2.8. Immediate and obvious differences are: speed - brightness of the viewfinder, speed of focus (the 200mm is very quick). Sharpness - My copy of the 100mm on my camera (a 5d Mk1) is stupidly sharp. Colour and contrast - little correction in light room. Distortion - very little. Hit rate - much higher. Finally, and highly subjectively, I think there is something a little magic about some of the shots you can get with an L lens. I think it's because they go beyond what the human eye see in detail and in depth of field (apparently that's about f3 although of course you can get this in a non-L lens) and because the images are none the less remarkably undistorted. But that's not saying you can't do that with a 35mm Zeiss lens or anything (on my wish list). Anyway, if I could start again, I'd never have bought that first lens, never have bought that 500D (don't ask) and would have done my best to get the following lenses - 16-35L, 70-200 2.8L (or maybe stick with my 200mm prime) and the 100L. I'd be hoping to get the 85mm and 135mm too, but that would be starting to get a bit mad. That said, I wouldn't have bothered with the 50mm 1.2L because my 1.4 is very good. Did I mention weather-proofing, ruggedness and build quality?</p>

<p>This happened to me, and so, inspired by this post, I super-glued the mirror back in place myself. Nerve-wracking, but it worked. Still holding several thousand shots on. Thanks!</p>

<p>Hi,</p>

<p>I just bought a used 5d off a well know internet auction site. It arrived, was fantastic for about 100 shots then I received err 1. Changed lens, same error. Changed to another lens same error. Unfortunately, this happened at my father in law's 70th birthday party. Did you resolve your problem, if so what was it? I was planning to change my button battery first...in the end I had to use the old trick of part un-screwing the lens on the mount and shooting everything at a fully open aperture in full day light - often at 1/8000 shutter speed. </p>

<p>Cheers</p>
