Ok guys I am fairly new to photography but I jumped right in. I bought a Canon 6d Mark 2. The Sigma 150-600mm lens, Sigma macro 105mm lens and a Canon 17-40mm f4 L series lens. I love the sigma telephoto but it's a little big for a hiking or walk around. I'm gonna purchase a canon 90d as a backup camera and to have the option of a crop sensor. Maybe I'm stupid I don't know but for long trips that I invest a lot of money in I'd like to have a backup.
I'm looking for a walk around lens for wildlife and hiking. I looked at the cannon 24-105mm f4 L series but I feel that it won't have the reach that I want for wildlife. Now if I want to take a scenic picture I feel I would use my 17-40 mm cannon and the 24-105 mm would not be used much. I keep looking at the cannon 70-200 mm or the Canon 70- 300 mm l-series lenses. I can get them both used in good shape for around $1,000 which is my limit for my other lens. My wife is getting upset with my new hobby. So my question is which lend would you choose or is there another lens you would look at for my purpose. I thought if I bought the 70 - 300 it would work good on the crop sensor and still be usable on the 6D. I figured it would give me plenty of reach for most wildlife shots in the woods. I also like how the 70-300 mm is a shorter lens but the 7-200mm can be bought with a f2.8. And I thought if I bought the 70- 200 mm I could always buy the extender for magnification or it would still be a middle ground lens for just all-around use.
