Originally posted by jersey I have 20-40 Ltd but despite being small it is still pretty large so I am thinking about getting either 21 or 40mm Limiteds for slim package. 15 and 70 (I have both) are bit too extreme. I would love to get both lenses, but this year it is last buy and I can get only one. Money needed for something else then photography.
If you want to save up for a GR, dont spend money on another lens.
You can do "street" with any camera, it comes mostly down to your behaviour on the streets, not if your lens is maybe 2cm shorter
And even a 15 or 20 wont make your K3 as compact as a GR
If K3 + 20-40 is too big, then probably K3 + 21 or 40 is also too big. This being said, a friend of mine does street with a Hasselblad.
