The 18-135 will fill virtually all of the focal lengths you will need that the 150-600 does not and is a pretty good lens. You have one other choice that will seem odd at first glance, but is an inexpensive stop gap measure. If you are intending to shoot closeups of flowers rather than landscape type photos the 150-600 is actually a decent macro lens when coupled with extension tubes. It is a little heavy for macro, but gives you an excellent working distance and after market extension tubes are inexpensive.

Need some feedback for purchasing my next lens.

I currently have a Canon 90 D. The only lens that will work with it is a Sigma 150 -600. It's great for my wildlife photography which is my focus, but I still need something else to continue to do other types of photography.

The budget is limited since the camera and lens are relatively new purchases. I want to do some landscape, flowers, and general all-around stuff. With my flowers, I typical lean more to close-ups, and I currently use my iPhone for that.

I am currently looking at trying one from Amazon (free return policy). The Canon EF-S 18-135mm f/3.5-5.6 is a Standard Zoom Lens for Canon Digital SLR Cameras (New, White Box). I know it's not a USM, but I wonder if it might be a stop-gap lens. I'm open to looking at other ones, but recently, this one has popped up.

I typically purchase from B& H. Also, open to refurbishment.

Any insight would be greatly appreciated!


Thanks!
