Best walk-around lens
Canon 18-200 EF-S Zoom Lens
"The camera body I use is a 70D. I've been using a Tamron 18-270mm f/3.6-6.3 lens as my go-to lens. To my amateur eye, it has given me 18 months of enjoyable photography (mostly nature shots), but I did not pay very much for it and it's starting to fail; time for a replacement.
In the Canon line of lenses, would you recommend the 70-200mm f/4 IS USM as a walk-around replacement for the Tamron that I've been using?
Thanks for your question about a good walk-around lens to go with your Canon 70D. I would not recommend the Canon 70-200mm f/4.0 as a replacement lens for your Tamron.
Your EOS 70D has an APS-C sensor. That has a "crop factor" of 1.6x, meaning the 70-200 lens would give you the equivalent angle of view as a 112-320mm lens.
I believe you would find that focal length range too long for general walk-around photography.
In your question you mentioned that you were happy with your Tamron. I'd suggest you go with a lens that has a similar zoom range.
If you'd like to go with a genuine Canon lens, I think the Canon EF-S 18-200 would work for you. I included a link at the end of my answer to some buyer opinions.
It's mid-range in terms of price, smaller and quite a bit less money than a 70-200 f/4.0 with a more useful zoom range.
If you shoot nature and landscapes, you really must have a wide angle focal length as part of your new lens. The 18mm setting on a lens mounted on the 70D gives you an equivalent angle of a 28mm on a full-frame camera.
If the price range is a bit too steep for the 18-200, you could compromise with an 18-135mm, which is about half the price of the 18-200.
If you are on a super tight budget, you could get a 18-55 kit lens, but I think you'd be disappointed in the limits of the zoom range on the telephoto end of this lens.
