I chose Nikon maybe four years ago because dollar for dollar , I thought the features offered by Nikon were much better, more megapixels more auto-focus points etc.
Now I realize some of those reasons were not so well founded, that often ones quality is ' noise limited' as opposed to sheer pixel count limited.
I wasn't exactly right about what was important quality wise back then, but I still think it was fine to have chosen Nikon.
Nikon had a big long list of short lenses , but not appropriate longer ones , Canon had a greater selection of longer lenses.
and so I was limited by my choice of Nikon .
But I was never going to spend what Canon wanted for telephoto lenses , and then lug them around in the dirt and rain.
(Tamron came to the rescue, with the 150-600mm which is much more appropriate for the birds than the Nikon 70-300 IMO.)
and going forward , I am going to pay close attention to the offerings by other manufacturers because with the generation of brand loyalty
the big two don't seem to be competing in terms of real quality , but rather in terms of gimmicky sales points and product strategy.
I dont need wi fi , I dont take movies , I would want a third manual wheel for ISO , I want sufficient buffer to clear the cache to actually GET
7 frames in one second rather than only two in two sevenths seconds ,, I dont need ISO 3200 if the noise escalates to unusable after ISO800
I dont need 1-8000th of a second shutter speed if I need to have a monster size aperture wide open to use with it..
and I can keep my own files organized.
Hope my rant is helpful , sorry if it isnt.
Its not that I dont like my 7100, I just think Nikon and canon could've provided me with more appropriate choices for my price range
rather than skimping on what functional features they were going to provide for me rather than gimmicks.
Try handholding a 600mm on target while changing the ISO with a finger from the left hand and a finger on the right turnng an adjustment wheel.
