New camera lens and part, looking for advise

[Sir-diealot]

I got in the final piece I need to use my new 70-300mm lens on my camera as well as an extra battery and charger for the truck to charge camera batteries and most seems to fit into the backpack I bought for my camera gear as well. Now I just have to get out there and do some shooting.

Can any of you offer any suggestions that may help me in shooting or just taking better pictures? My current camera is a Canon eos M50

This is the backpack I bought to carry it all. https://smile.amazon.com/gp/product/B00009R6TA/ref=ox_sc_saved_title_6?smid=A17MC6HOH9AVE6&psc=1



The adapter I had to wait for.


Pics of my dog and minimum and maximum on the lens, I had forgotten to turn on image stabilization on both, so not the greatest pictures.

So I am still hoping for some advise, I picked up a rain jacket for my camera, not the one I really wanted but it will do for now. Here is a link to the one I got and the one I wanted if anybody is interested.

I also picked up some filters for both lenses, though I have since been told I should not have really bothered as they are not used much in wildlife photography, the one for my smaller lens which I use for landscapes will benefit from them though.
