[18-135 mm or 55-200 mm lens?]

I made some of my best travel pics at 200mm, that keeps me from switching to the 18-135.

 

Over the years, I found the 14 + 18-55 + 55-200 to be my favourite travel kit, if I have time to change lenses. Not too heavy, not too expensive, covers a wide focal range with very good to excellent IQ. As a bonus, the 14 and 18-55 share the same lens hood.

[Which 3 primes combo is your ideal setup?]

14, 27, 56

 

... and if you say that 14 is too wide, I'll literally pull an ace from my sleeve: the Ricoh GR with its super sharp 18mm/F2.8
