The recent "Service Life" thread got me thinking...
"Service Life" http://www.fredmiranda.com/forum/topic/1181905
I did a bit of detective work at CPS Canada, and produced a pre-release beta version of a Canon Lens Service Database that I'll work on over the next few months.
Here's two graphs of service status for a variety of Canon prime lenses, mostly L-series and TS-E, based on CPS Canada service information. The first graph shows the lenses that are currently serviced by CPS Canada, plotted as unfilled-circle symbols with the year the lens was introduced on the horizontal axis and lens focal length, f (mm), on the vertical axis. The second graph uses a similar format with filled triangle symbols to show lenses not serviced by CPS Canada, as defined by their absence from the CPS Canada list of lenses serviced. The 'year introduced' data are from the online Canon EF Museum 'year marketed' data. I also have preliminary data for zoom lenses, but I don't plan to tidy it up for show, at this time.
Obviously, there is no simple relationship between the year of introduction and the year that service is no longer available. In some cases, a pro lens is dropped from the service list some years after it's been replaced , but in other cases, the older versions of pro lenses are still serviced long after their replacements were introduced. I'll identify specific lenses in future releases, once more data has been obtained, including 'year discontinued' data, as mentioned by FM member big country in the "Service Life" thread link shown above.
The most recently introduced lenses that are no longer serviced are the EF 400/2.8L II (1996) and EF 500/4.5L (1992). The oldest lenses that are still serviced are EF 15/2.8 FE (1987), and (all from 1991) EF 14/2.8L, TS-E 24/3.5L, TS-E 45/2.8, and TS-E 90/2.8.
Of course, the data shown here does not include many excellent EF non-L lenses that are widely used, such as the 50/1.4 and 85/1.8. I've asked Canon Canada if they can share the list of all currently serviced lenses with me, but I'd say that getting it is 50/50, at best. Also, I haven't included the EF 1200/5.6L (1993, not serviced) lens in the database, for reasons related to graph scale.
I plan to publish regular updates for Canon prime and zoom lenses on my web site, along with the Lens Price Database, Lens$db. Maybe it'll include cameras, too... I'll post a dedicated FM thread when version v.01 is ready. It'll take a while, and so don't hold your breath.
In the meantime, I'd be happy to log "year discontinued" and "no longer serviced" status for any Canon lenses and DSLR cameras, as long as it's from a reliable source, not "I think I heard...". Please send such info, including a brief description of the source, to me by PM or email to the Lens$db site.
P.S. I've already included data from an FM thread in this data. The current CPS Canada service list (dated 2012-01-25) includes the 85/1.2L (1989) in its list of serviced lenses, but John Meloy (johnnydanger) recently noted that it's no longer serviced, http://www.fredmiranda.com/forum/topic/1171870/0#11171023.
