I am shooting on a 7d, and currently using my tamron 18-270 which I bought with the camera, and am looking at upgrading to a few good quality lenses.
The first one I want is either the 24-105L f4, or the 24-70L f4, however I am undecided on which to get. Why is there such a price difference between them? What are the pros and cons of each?
I want it for a bit of a variety of shooting, and plan on using it for my main lens whilst I travel south america at the end of the year- Chile, Argentina, Peru (Machu Picchu!). Whilst I will still have my tamron for the extra reach as I will not have the funds to buy 2 new lenses before leaving.
I like to do a variety of photography- landscape, portraits, do a lot of whitewater kayaking photography, plus just every day random photos. I do know neither are that wide so are not fantastic for landscape.
Any thoughts would be greatly appreciated!
