Hello all and thanks for taking the time to help me out, Im still new to photography and just do it as a hobby. I really would like to take on Landscaping and see where that take me. I would really like your input as I sometimes feel like my lens being a Full Frame lens isnt compensating my camera, also read that its not suited for APC-S sensor if landscaping is what your going. If anyone has used this lens on a APC-S and gotten beautiful resort to calm my overthinking mind ill highly appreciate it.
Currently using:
Canon EOS 60D
Canon 16-35mm f4 L
Hi and welcome to the forum!
That canon lens you own is an awsome lens.
There are a few discussions in this forum whether a longer lens (telephoto lens) is better for landscape, or a shorter one (wideangle lens - like yours). Both camps have their fans, so you can´t say that this or that lens is bad for landscapes. It´s your preference whether you want to shoot really wide, or rather not. If you do, then you can easily sell your lens and get an APS-C ultra wideangle for the price. But be aware that if you ever buy a full frame camera, you´d wish you hadn´t sold it

.
If you didn´t know: on your camera this lens covers 25,6mm to 56mm. Wideangle lenses on APS-C are available from around 10mm. I once bought the Tokina AT-X 11-20/2.8 Pro DX and was really happy with it, because I´m in the ultrawideangle landscape camp.
Something to consider for your particular images:
#1 - there is some motion blur in the shot (probably due to camera shake)
#2 - horizon is pretty off - it sure is difficult to shoot out of a driving car, but you could always bring the camera in again, check the results and reshoot if you see the horizon is off.
#3 - if you had a wider lens the rooftop (which you should have avoided

) on the left would have been much more porminent in your frame and much more difficult to avoid
#4 - if you had a wider lens, the houses would have been much smaller, and the foreground (which is a little dark) would have been much more prominent - usually you would like to have the foreground brighter the more prominent it is. Maybe if you had waited a few more minutes/seconds the cloud (if it was one) would have been gone and result in an easier, better lighting situation.
If many of those images are really taken out of a car, as astronikon suggests you should give yourself a little more time and thought to shoot these kind of images - otherwise they are mere snapshots, no matter what camera/lens combination you use. Except for #2 which I like best - this has to be shot out of a car and doesn´t look incidentally as the other three.
#Derrel lately said in a post: "make the image, don´t take it". That is a wise quote that sums it up pretty much.
