On the left, the Pentax SMCP 50mm f/1.7. On the right, the Pentax SMCP 50mm f/1.2 you will notice that one lens is much bigger than the other. The question is, which one would you most likely want to drag around with you every day for a month?

The same rules apply for zoom lenses especially fast ones as the speed goes up so does the size....the the DO technology from canon was surprising...but those lenses have bokeh that reminds me too much of the bokeh produced by mirror lenses.
not bad example, but in this exact scenario (with K55/1.8 instead of 50/1.7) I prefer to lug the 50/1.2 with me, simply because of 8 blades vs 6 and hence huge difference in OOF with highlights...

to OP though, indeed f2.8 60-250 would have been too big... and way too expensive. The f4 version is around 1000GBP, the f2.8 would cost around 2x as much.

That battery and charger looks an awful lot like the ones in the K10D/20D.
