450d vs 40d 敗邊部好...@@
大家都係DIGIC III ....
各師兄俾點意見吧~~!

[Tester 1]

"敗"為目標！必以最貴為依歸！
記住唔貴唔好買啦！

u ask this question too early. nobody tried 450D. how to give u idea? ^^

[twheddie]

40D的凁度和機身強度,對焦設計,手感,尊業感,勝過450d,且可換對焦片.

[scwong]

But, the 450D resoultion is higher then 40D, the number of focus points are equal, live view may better then 40D, 450D body will become more professional, etc

邊個話對焦系統一樣架,450D得中間一點係十字,40D有9點的.

[scwong]

I mean number of focus point!!!!!!!!!!!!!!1

[cy001]

but the live view of 450d is better than 40d.

[scwong]

Yes, I said before.

The different between 450d & 40d is very small, and also part of the function is better then 40d such as live view, resoultion, cost, etc.

各c兄~!
想問 40d 個"9點十字型對焦點" 同 450d 個 "9 點自動對焦，中央點為 f/2.8 十字型"
有咩分別??@@

[scwong]

The main different:
- Look like more "professional"

May be someone will say the noise is less then 450d, but I think sometime you can't easy to see the different. On the other hand, fps for 40d is faster than 450d, but, I want to know how many people need a faster fps? How many time you need a faster fps?

[scwong]

十字型 focus point will more accuracy. (If take photo within a lower light envirnment)

[scwong]

十字型 focus point will more accuracy. (If take photo within a lower light environment, you can easy to see the different)

For 40D ALL 9 points focusing points are cross type it can be sensitive to both vertical and horizontal contrast on F5.6 or large apeture lenses.

For 450D only the centre one of the 9 points is cross type, the other 8 points are not they are just horizontal type.

The 40D AF on low light situation is much much better than 400D, I think the 450D is just similar to 400D on AF. I consider the 40D AF in low light are even better than 5D.

(PS. I have all mentioned bodies except 450D, not yet available)

[scwong]

Yes, I think so.
I had already tested the cross point and non cross point focus on low light environment. The cross point will more easy to focus and accurary. It is very easy to see the different.
