These have been made with the Tamron lens and then cropped and processed.  For a 16+ zoom lens, it is OK; but, I still prefer a better prime lens that is smaller and lighter.  The question for me is, will I carry this Tamron lens with me most of the time just in case I see something or only use it when I know I’ll need it?  I think I know that answer, but I’m still trying to use it most of the time to see if/when I can leave it on my camera.  But, why would I wish to bother carrying it just in case, or to make images like these?
