- Touch screen interface allows for easier controls and more options than just using the buttons from the G1x.
- Shoots MUCH faster than the G1x. Can shoot 5.2 fps compared to 1.9 fps.
- Two control rings around the lens, and one of them is customizable to ISO, aperture, etc. Makes manual mode just as easy to use as most DSLRs.
- VERY comfortable in the hand. Not too big, not too small.
- VERY well made. The build quality is amazing. I feel like I could drop this thing 50 feet and it would be just fine. Its kinda heavy, but I think that is from the metal build.
- Autofocus system is much better, instantly focuses on pretty much anything.
- OLED screen is better than the old one. It has a noticeably better resolution for sure.
- A wider f/2 aperture allows for better low-light pictures
- Better wide angle, better zoom, better lens in general, Wifi is nice feature as well.
- Definitely smaller than the G1x
CONS:
- No optical viewfinder. Optical viewfinders are on the way out in general, but the OLED screen is very glare prone and is extremely hard to see what you're taking a picture of in high sunlight. Its just not bright enough for heavy sun. If you DO want a viewfinder, you have to pay $300 for the electronic one that attaches to the hotshoe.
- Battery life is CRAP. This is probably due to the screen being on full brightness all the time.
- less true resolution than the G1x. 13.1 megapixels vs 14.2 megapixels.
- picture quality seems to be exactly the same as G1x. I couldnt tell a difference.
- Price
- Picture on screen can be very different than the picture that comes out when uploaded to a computer. This was definitely very frustrating.
Нет видоискателя, юзер не смог отключить вифи. Шире апертура, см. цитату из вики выше. Отличий в картинке не заметил. Кенон хочет продать больше комплектующих.
