just order a tamaron af 28-300mm
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/
Do you find your clip is sort of floppy on your pack? I bought one of these to use with my Canon 40D and a pancake lens and I could never get it dialed in.I see that you already ordered a lens and it is a good choice. I had it on an older camera and loved it for what it was. I currently carry around a Nikon D750 with the Nikon 28-300 and a Rokinon 14mm f/2.8 for ultra wide shots. There are newer ultra wide lenses out now with auto focus that would make a great companion to your superzoom.
I use a lot of the peak design stuff. I absolutely love the clips! I have a clip on either strap of my backpack, one holds the camera and another holds the lens kit. The lens kit can hold two lenses so what I do is remove the one on my camera, click it into the lens holder, rotate it and grab the other lens and go. Very quick to swap between lenses and very low risk of dropping or contaminating the lens or body. Also, having the weight on the backpack removes the weight off of your neck and also acts as a counter balance for the things in your pack. The camera doesn't bounce around, is always in reach, and is very sell protected since the only way you are likely to hit it on anything is if you trip and face plant. I do keep the camera attached to a strap just in case I drop it, but it is really there for quick set downs or an oops, rather then holding the weight of the camera.
