<p>To a degree the same pattern applies with Nikon and Canon ranges. There is very little collectors interest in the Canon FT or Nikkormat FT/FTn as they are big and heavy and there are better later options for users but the late rangefinder models are popular with collectors and users. Some of the rare Nikon F sub-species are very collectable especially in good clean condition, but worn, useable Nikon F's are not especially valued.<br>
There are exceptions, for example more Canon P cameras were produced than the entire range of Canon R series SLRs so a clean working Canon R2000 will fetch a higher price than a P simply because there are very few out there. </p>
