Nice photos!I would choose the current Tamron 16-300mm lens. It is for crop bodies only, but it is wide enough for some landscape work, and long enough for some wildlife and small and light and fairly inexpensive. It is sharp as well. Most of my images were captured with a Canon 70D or a 7D MK II
Since the zoom range is so large, you never really need to swap lenses in the field, hence your sensor will stay cleaner to boot. Used with LightRoom it will have no color aberrations and the images sharpen very nicely.
I have had mine for about 2 years now and have over 8500 frames captured with it, on land, sea, and glacier surfaces.
I have a few images shot with the Tamron 16-300mm lens here so you can see the lenses potential and image quality - https://pathfinder.smugmug.com/Other/16-300-Tamron-Zoom/
I wish I knew about this lens - it would be great for MFT camera with an adapter.
