Which is better, Canon IXUS 220 HS or Panasonic FH25? My junior high school students like photography.

Hello! Of course, you should choose Canon IXUS 220 HS equipped with "high-sensitivity CMOS (back-illuminated) photosensitive element" with excellent image quality. The current price of Canon IXUS 220 HS is 1369 yuan (JD.COM Online Mall). Panasonic FH25 current price 1300 yuan (computers and digital cities are everywhere). Canon IXUS 220 HS has the following advantages over Panasonic FH25: 1, shooting full HD movies of 1920 X 1080 (Panasonic FH25 can only shoot SD movies of 1280 X720). 2. With the addition of Canon's "HS high-sensitivity system", the picture quality is further improved, especially (Panasonic FH25 does not have this configuration) 3. The photosensitive element is upgraded to "high sensitivity CMOS (back-illuminated)", which has higher sensitivity and better image quality. (Panasonic FH25 is equipped with ordinary CCD). By the way, about "back-illuminated CMOS sensor":

Compared with the common CCD sensor, the back-illuminated CMOS sensor can avoid the shielding of metal lines and transistors by illuminating the side without wiring layer.

Back-illuminated CMOS sensor has great advantages in sensitivity (S/N), and its photosensitivity is claimed to be twice that of the same size sensor in the past.

It is precisely because of these advantages of back-illuminated CMOS sensor that digital cameras equipped with this product usually have the following advantages:

1: It has a high tolerance (it can be understood that high-light parts are not easy to overflow, while low-light parts are not easy to be underexposed).

2. Have faster data throughput (usually supporting high-speed continuous shooting and even full HD video shooting).

3. Better imaging ability in low light (at high sensitivity, for example, the quality of shooting night scenes is much better than that of traditional products).

Therefore, back-illuminated CMOS can be regarded as synonymous with "high image quality" at present.

Canon IXUS 220 HS is a digital camera equipped with "back-illuminated CMOS".
