Originally posted by ChrisJ All lenses have compromises in their design, none more so than wide range zoomes. For me they are a compromise too far.
I feel the same way.
Like the OP, I upgraded to my Pentax DSLR from a "superzoom" bridge (a Fuji S5100 in my case). I initially feared I would miss the versatility of the 10x zoom, but I still chose the Sigma 17-70mm as my first (and only) lens at the time (the "105mm equivalent" focal length covered 75% of my shots with the Fuji).
Not long afterwards, I purchased a DA50-200mm to cover most of the gap I felt I was "missing". Well, after nearly two years it turns out I don't use the 50-200mm all that much... I'm happy to have it when I do need the longer reach, but considering how seldom that happens, I am very glad I chose to not compromise the IQ by going with a superzoom.
One of the main advantages of a DSLR is the possibility to change the lens, and therefore use one that is most suited to the pictures to be taken. One should not shy away from that, IMHO.
BTW, my current "travel" kit consists of the aforementioned Sigma 17-70mm, the DA50-200, and the DA12-24. And the 12-24 sees
a lot more light than the 50-200...
