I spent last week in Berlin doing the tourist stuff. Random observations:
* In the tourist crowd, ~60% had a camera, of those ~75% were DSLRs, the rest being mostly very small cameras (like Q and whatyouhave). Very few bridge cameras.
* There was a significant number of regular people carrying FF cameras. Regular as in family on vacation, non-geek, taking snapshots people.
* As already stated by others, most DSLRs had kit lens on it (and often lens hood the other way around...), or some variant of a superzoom.
* I have seen very few (but more than Pentaxes) top quality (or price) lenses, all of them zooms and obviously most of them with people looking like pros (as in going in pairs to sites and lugging a couple of backpacks of photo equipment).
* I don't recall noticing any primes, apart from fancy crowd with Leicas and vintage film cameras. All of these were young and, well, fancy.
* Of hundreds of DSLRs, I have noticed a grand total of 4 (four) Pentaxes. One K-r, one K5II, the rest I didn't see the model. FWIW, could be I have seen only two twice as we (as in tourists) were visiting the same sites all over the town.
* I visited two Saturn shops (electronics and like department store). One in Kurfürstendamm street had some cameras (K50/K5II) and very few lenses (DA50, 35LE, 100WR and maybe another one or two). The other on Alexanderplatz had a bigger selection of both; K50/K500/K5II/K3 and DA 15/35/50/70/100 and DA* 16-50 & 50-135 & 200 and maybe another one or two. Haven't seen Q anywhere (and I was looking for it).
* I have seen maybe 10 people carrying a tripod. Of these, one was massive with FF, one was a sort of portable with another DSLR and the rest were portable with cameras the size of a pack of cigarettes. I didn't get it. What for?
* I found user mode with all auto settings very useful for handing the camera to random people on the street. Even though I was trying to ask people who have a DSLR and look competent using it, I was rather disappointed with the results. 80% of time the composition was really bad. Actually I got more keepers from people NOT carrying a mean looking DSLR.
* I took with me Tamron combo 17-50 & 70-200. Even though the latter is heavy, it's not too heavy provided I really needed it. I just didn't need it all too often. Most use it got was in the zoo (~90% of the photos there). I don't think I will take it to the next trip.
* To make me feel less bad, there were a lot of other regular joes lugging similarly sized (& heavy) lenses
