Repairing stuck focus on a Canon 50mm f1.4 USM Lens

Here is a sped up video of me fixing my beautiful Canon lens. It actually took me about 1.5hrs to complete. I used this webpage as a guide. http://www.fotomozaic.ro/artikel.php?s=1&categ=0&idstory=225

Ya I kinda thought so, Maybe sometime I'll look into getting a 35mm film slr if they're still made new or a nice used one in good shape. 35mm film slr's last a life time if taken real good care of. Thanks again. It's a shame that dslr's only last for so long and they seem to overheat and not work so good,so you gotta shut them off some times to let em cool down a bit then it an be used again. Don't get me wrong dslr's are are awesome as well and I like my Canon 7D.

@krazy4baja I have about 80 film cameras. One of my favorites is a 1957 Leica M3. I use it the most. I do also have a few older 60's-70's SLR cameras that I use sometimes. A 1973 Canon F1 and a few Pentax Spotmatics too. But I prefer rangefinder cameras for lower light photography. Not many companies are still making film cameras anymore.

Ok thanks, Ya I miss the days of 35mm film SLR'S. I had a Pentax super program with 50mm lens which I really liked. I made the mistake of lending it to a friend for a wedding and it ended up damaged beyond repair. Really don't care for DSLR'S but what ya gonna do unless 35mm slr film cameras are still made and you can still get the film developed. I know film still can be developed but everyones using dslr's now.

@krazy4baja You can get film developed at alot of places around here in 1hr. I develop my own black & white. I don't use and digital cameras. Film just has a more beautiful look. Digital looks so steril and I can't stand it. FIlm for life for me =)

Is this a common problem on newer lenses in the L series or the cheaper canon 50mm. I won't buy one if this is the case.

[AlexisG73]

I don't think its a issue with the L series. These lenses are all plastic where I believe the L series are metal. I miss the days of manual film cameras where most lenses were built tough as nails.

Hey what size screwdrivers did you need to use to do this? Mine got messed up at a concert and I'm thinking of just going ahead and trying it myself.

You work fast.

not sure about the grease as dirt will stick to it. the nylon will slide with out it

[redandbluebeater]

@AlexisG73 Only parts of the L series are metal. Canon has almost phased out all metal designed lenses.

@UltimaGaina I'm also getting this error about cleaning the contacts after repairing the stuck lens. Autofocus works, 1.4f works, but like you any other aperture i get the error. What exactly did you do to pop the lens back in cradle?
