Telling someone to buy a camera by feel...is a nice way of saying that the gear doesn't' really matter.
I would say this except stating about the different "classes" of cameras.
You can compare specs all day long, but in comparing specs from what I see, the equivelant camera classes through all brands of cameras are similar enough not to matter. You certainly wouldn't say "gear doesn't matter" comparing a D40 and a whatever Canon topdog is (5DMarksomethingorother..) It's obvious a Canon Marksomething is going to be a much better camera similar to an XS vs. D700. Specs do matter in that respect when you want better ISO performance or something, of which you would be jumping to another class of camera rather than another brand.
i think ANDS! said it best when he bluntly stated:
"This nonsense about "camera feel" is silly - your muscle memory will adapt to the fell of WHATEVER camera you get. Unless a manufacturer is building camera bodies with spikes in them, or that are so ergonomically **** that a person suffers from using it - then yea, camera feel would rate somewhere around "What media does the camera use. . ." as far as importance to my decision. "
Muscle memory doesn't matter, IMO. If I like the layout of Nikon, I am not going to like the layout of Canon from what I am seeing with looking at them. Ergonomically, with a Nikon (D40) in my hand, my finger was on the shutter and my thumb was on the wheel. My finger didn't move off the shutter to play around with any button. With Canon (XS) where is the wheel? It is right in front of the shutter (behind? can't quite remember now.) Finger has to leave the shutter to adjust settings. That does not make ergonomical sense to me, I want my finger on the shutter and ready at all times.
I started the thread asking about the similarities of cameras as you move up the line, which is what I would believe sparked this thread. I've sinced looked at images of the Nikon and Canon lineups. What I see is through the entire Nikon line, the wheel is on the back to be used with the thumb while the index finger stays on the shutter. With those that have 2 wheels, I see the back wheel and also the 2nd wheel on the front of the camera to be used with the middle finger while the index stays on the shutter. With the higher Canons, I still see the wheel up near the shutter so that you still have to remove your finger from the shutter or else it looks awkward to use.
That is the difference in ergonomics that I see and that I was wondering of when I started my thread. That to me is important. It has nothing to do with muscle memory. If you don't like one layout, you are still not going to like the layout even with muscle memory. If it doesn't make sense to you, muscle memory isn't going to change that. It still isn't going to make sense ergonomically.
That's my thoughts.
And.... good discussions here lately. I'm enjoying them.
