I'm looking at a used Canon EOS rebel T6S software w/a shutter count of 7K. Although that kind of sounds like a lot, I wanted the input of the group. Thanks all.

Wow, I hadn't expected so many thoughtful/useful replies in such a brief interval. Thank you all!

Thank you all. Interesting/ironic, the problem came up on a trip to Alaska, Wingpilot's backyard, when I was trying to get a picture of a buck like the one in MT Shooter's post. At the time I was using a Canon 70-300mm zoom w/a Canon doubler so, 600mm. Although I hadn't thought about it, it does look like atmospheric interference reduced contrast etc., probably played a part. Unfortunately, because getting closer is still the best solution, my days of eagerly hoofing it through bad bush for a better picture are sadly behind me. Valuable input, Thanks all

As this is my first post, I'm hoping veterans will bear with me. I've been using a 10.1MP Canon Rebel XTi DSLR for some time w/ok results. I'm running into problems when, having reached the maximum focal length of my longest lens, I still need to get closer/want to zoom in on or blow up a still too distant object. Of course, back home, at the computer, the more I attempt to enlarge that small part of the frame, the more image quality suffers. I'm hoping to obtain better/clearer images by upgrading to a 24.2MP Canon EOS Rebel T6s. My question is will an upgrade from 10.1MP to 24.2MP significantly improve image quality when I'm attempting to enlarge a small part of the picture? Thanks all.
