Originally posted by hjoseph7 Is the 24-70mm f2.8 a little too big and heavy for your taste ? Although this lens looks compact in the pictures, this is a huge lens that weighs almost 2 pounds and has an 82mm filter. That is about twice as heavy as the 18-135mm. If you attach this lens to the K-1 you might as well call it a Studio camera. I don't know are there any other lenses as heavy and big as this in Pentax's current lineup ?
It's a BIg Boy lens with Big Boy quality on a Big Boy camera, Hjoseph.
In wanting similar products to Nikon and Canon, be careful what you wish for!
Luckily, we have choices. I have the Tamron 28-75 f2.8: much smaller and has really good IQ, but can't be expected to go head-to-head imagewise with its 82mm filtersize brother - a lot less glass is inside it.
