What are the things that make 40D better than cheaper XTi? Aside from having faster Frame per second and Higher
Aside from having faster Frame per second and Higher ISO.
Answers:
Build part
40D has a partialy weather hermetically sealed magnezium body
Xti has a plastic body
40D's shutter apparatus is designed to last almost 100,000 actuations. Rebel's are typically 60-70,000.
40D's top shutter speed is 1/8000 sec where on earth sti is 1/4000 sec Yes, the 40D is weather hermetically sealed, but this is not water proof. Moisture can still draw from into the camera, but it is a but harder to do that than with the 30D. The 40D allows you to shoot Raw photos surrounded by both the automatic and creative zone on the camera mode selector. The camera is capable of shooting at a burst rate of 6.5 fps plus the shutter workings has two motors to cycle the mirror vs. the Rebel XTi (EOS 400D) using one motor and a spring. The standard of the images produced on the brand new 40D are more comparable to the images produced on the 5D than the 400D due to the anti-noise technology to be precise a part of the Digic 3 processor surrounded by the 40D compared to the Digic 2 processor in the 400D. The 40D is able shooting at 3200 ISO on extended mode and the pictures taken at 800 ISO are very usable compared to the smaller number than stellar output 400D at this setting.
All around, the 40D is a superior camera to the 400D, but you should expect that considering that the 40D runs around twice the price of the 400D on the street. And I am going to say that the 400D is a great camera as economically. You will not be going wrong purchasing it over the 40D. It is just that the 40D is indeed worth the extra money.
