:confused: what is the best size lens I could use for landscapes and wildlife and what make :confused:

Best is such a relative term you haven't really given enough information to go on.
What body is it to fit and what is your budget are some information we need for starters.

For wildlife, you need a telephoto lens, the bigger the number the better (and the more expensive). This is so you can get a close up shot of a wild animal from far away - so you don't scare the animal. You will also need a tripod to hold the camera and lens steady to avoid blur caused by hand-holding a long telephoto lens.

Most landscape photos are taken with a wide angle lens, the smaller the number the better (but not a fish-eye lens). You also need a tripod as most landscape photos are taken with a small f-stop (big f-stop number) which requires a slow shutter speed, and again you will get blur if you try to hand-hold the camera for this type of shot.

You may be tempted to get a zoom lens that goes from wide angle to telephoto. However, the longer the zoom the lower quality the images so for best quality you need 2 different lenses for these different types of photography.

Sigma makes a supertele that goes from 50-500 mm. The images from this lens are not as crisp and sharp as one from a dedicated lens at a given focal length. The 50mm end isn't wide enough for most landscape photography. On the other hand, this lens is around $1000, which is much less than the better quality lenses, giving you a chance to learn about this type of photography without a huge investment in top-quality glass. This lens is available in Canon EOS, Nikon (D), Sigma, Pentax, Sony and Four Thirds mounts.

For landscape photography, use "normal" or wide angle lens. It doesn't have to be fast lens since you will use tripod and long exposures anyway.

24mm works for me, just wide enough but no soft edges.

24 mm is great for landscapes, but not for wildlife photos. You need a long telephoto to get photos of wildlife, not a wide angle.
