Interesting comparisons. It takes a brave person to admit that, at
least in your case, one can spend more money and end up with less.
Your honesty is greatly appreciated.
Hi David:
Thanks for the compliment regarding my honesty. While I appreciate
your comment, I don't want to leave you with the wrong impression
about what is more and what is less. I really did not end up with
less (I paid more to get exactly what I wanted). You have to bring
the whole picture into play (and it is a very complex picture).
I love going to the zoo. The 7i just did not have the necessary
range. With the Canon 100-400 mm zoom and taking into account the
1.6X crop factor of the 10D, I have one heck of a telephoto lens.
Another thing - my resolution comparison has to be considered very
carefully. While the 7i was slightly better than the 28-135, we
have to take into account that a tripod and flash was used.
Outdoors, during real world hand-held testing of resolution (about
20 feet away from the target), even at about 1/1500 sec shutter
speed (if I remember correctly), the IS designed into the 28-135
proved it to be the better lens overall from the standpoint of
effective resolution. IS is a pretty fantastic tool; it improves
the effective resolution of the lens during real world hand-held
shooting. If the A1's AS works well, and if Minolta can get around
the problem of losing focus if the subject moves during
acquisation, then that will be one heck of a camera.
But wait, there is more. When I go to the zoo (and sometimes
during scenic photography) I prefer to shoot with a polarizer
(animals with shiny coats look MUCH better when a polarizer is
properly used). I still like to have a shutter speed around 1/500
sec to make sure motion blur caused by the subjects movement will
not screw up my picture. Well, believe it or not, I can shoot the
10D at ISO 400 and 800 without much concern about in-camera noise
and the harsh contrast normally encountered at high ISOs.
Fact - the 10D AF acquisation speed is head and shoulders above
that of the 7i. I also love to take pictures of my grand-children.
Focus lock and tracking is a very important factor when you shoot
children at play. The 7i was incapable of tracking anything in
motion without losing focus. With the 10D, I can acquire and track
focus without a problem (oh what fun).
So - no surprise to anyone - photography is full of tradeoffs.
Don't get me wrong - I love the 7i. It is a small high performance
camera more than suitable for 90 percent of the applications out
there. For sure it will be with me on all flying vacations. The
7i is just a perfect camera - very powerful features and capable of
great pictures without breaking your back carrying a camera around
with fifty million lenses in tow.
