點解天文攝影多數用CANON機?仲要好多人用450D?
Other than weight (which can be a problem in balancing the scope), 450D has the same CMOS as 40D and 500D has the same CMOS and basic image software as 50D. So one gets the same quality as of intermediate level ones using the entry level cameras.sodium 寫: also 450D cheaper in 2nd hand market, and much lighter than X0D to reduce the loading of mount?
Of course, for general photography, 50D has some advantages over 500D such as faster multiple shots, faster and more accurate focusing ... But none of these are useful in astrophotography (we use bulb as speed and never use autofocus).
