[1] History
10 years ago when digital compact cameras started to enter the consumer market, I knew right off the bat they were going to be revolutionary. For the first time photographers didn’t have to worry about wasting film or time scanning them.






I liked the A60 so much, I replaced it with its successor, the Canon A610. Looks the same, but with overall improved features + swivel screen in the back! This was probably my all time favorite camera — it did everything I wonderfully.
Canon A2100IS (bought in 2009)
Three years later, I decided to upgrade again with Canon, and blindly picked the best model in the Canon Powershot A family: the A2100IS.
[2] Problem
Unfortunately I didn’t realize the A2100IS was actually a step back from the A610 in terms of usability, despite having a newer processor, more megapixels and image stabilization. Two main things it failed at (which I did not realize until afterwards):
- Sensor size reduced: difficulty burring backgrounds and hard to shoot in low light situations
- Slower max. shutter speed: won’t be able to capture fast moving objects
Had I done more research and known these mattered, I wouldn’t have made such a bad decision! Unsatisfied and disappointed, I went back in search for a more capable camera. Naturally I considered DSLRs, as they perform in every way better than P&S. For one thing, with a larger sensor size, DSLRs capture shallow depth of field/the blurry background extremely well:

Right: regular compact P&S camera

[3] Solution


Compact camera: 1/2.5″, 1/1.8″, 1/1.7″, 1/1.6″
Micro four thirds: 5-9x compact camera size
DSLR: APS-C sensors
