Is the canon ef s 18 135mm f 3 5 5 6 is stm good for wildlife?

It's a walk-around lens more than a wildlife lens. On an APS-C Canon it frames like 29-216mm on full frame, which is handy for birds in a park or a deer across a field. But at the long end it drops to f/5.6, which is slow for fast-moving animals in dim light. The stabilisation helps when you're shooting handheld.

If wildlife is what you care about most, you'll want a longer telephoto. The animal is far away and won't wait for you, so reach matters a lot. Read Wildlife and sport before you buy. For a cheaper way to try longer focal lengths, Buying used explains why good lenses hold their value and make experimenting less of a gamble.
