Hi Gang, One of the most common shutter problems with older (and sometimes not so old) EOS bodies is shutter bump rubber rot - where the rubber turns to goo and coats the shutter blades. It's a very expensive repair due to the labour cost involved.
I've noticed that some models seem more affected by this than others though. The early 650 and 630 (600) are commonly affected but the 620 apparently not so. The EOS 10/10s and 100/Elan are commonly affected, but I've never seen even an old 5/A2e/A2 affected by it. Likewise the EOS 1/1n seem unaffected. Even the later model EOS 50/50e/ElanII/IIe is affected. The 1000 and early Rebel series also suffer the problem. One common thread here is that the high speed shutter models (1/8000) seem to be more resistant to this problem. The 620 although with only 1/4000 (only!) still has 1/250 x-sync and has a dual shutter mechanism (I'm told) similar to that of the 1 series. The 5/A2e models certainly seem to have a different shutter design to the earlier 10 and 100 models and it's possible they also have a dual shutter design similar to the 1 series (they look somewhat similar) and maybe the bump rubber is more durable??? Does anyone have any empirical or technical data that they can add to this? My observations are purely just that - with no wider or scientific survey or data to base this on. So - have any owners of 620, 5/A2e/A2 or 1/1n cameras had shutter goo problems? It's a major cost to repair and may help when deciding on a used camera....
