This camera was better than its previous version because of the change in the high-resolution sensor, i.e., from 8.2 megapixels to 10.1. It also had better noise control than canon 30d.

Its memory power was also storing so that it could take a lot of pictures in a frame per second.

Canon 50D is a part of the EOS series. It succeeded Canon 40D and was preceded by canon 60D.this camera was launched in the year 2008. Its characteristics and features are very similar to canon 40d.

But Canon 50D has a higher resolution i.e. 15.1 megapixels. Thus its is better than canon 40d for shooting purposes.

It had a large memory so that pictures could be taken continuously without any buffering. Frames per second were also increased from 5 to 6.5.

Canon Wireless File Transmitter can be used, and a new sensor cleaning system was introduced.

What is Canon 50D?

Canon 50D was released in the year 2008. It succeeded Canon 40D. The LCD screen size of canon 50d was similar to 40D, but it had a higher resolution than any of the previous versions released.

50D is the last version to be having a compact disk or memory drive for memory storage. Because after that, all the versions after 50D doesn’t have it.

It had a higher pixel count, i.e., 15.1 and higher resolutions for shooting.

Shutter noise is reduced in 50D. It has a LiveView just like 40d. Improvements in 50d include ISO standard mode from 1600 to 3200 that can also be increased to 12800.

The burst rate of 50D is almost similar but a little less than 40d, i.e., 6.3. Its processor is very good and uses DIGIC 4 image processor.

Its processor is fast, improved colour rendition delivers responsive operation, and has near-instant start-up time.

The detailing of images in 50d is very clear than previous LCDs. It also had two auto-focus modes, one in HDMI port and the other in LiveView mode.

Its APS-C size sensor has 5 more megapixels than 40D. In 50D, canon eliminated the gap between photosensors and microsensors. In 2013, magic Lantern video support was developed in 50D.

Its weight is 790 grams. It has an interface of USB 2.0. File Formats supported in 50D are raw, sRAW1, JPEG, and sRAW2.
