As a consumer, I would probably be the best designer of Canon's next gen G series compact. Definitely a lot better than a geeky, excitable engineer in a lab. If I were asked to design the G12, I would most definitely include the following:
- A larger sensor, maybe a 2x crop of even a 2.7x crop sensor (1"). Most probably CMOS. At this size, Canon can afford to incorporate some clever tricks in the CMOS sensor.
- To cater to the larger sensor size, I have designed the lens to be about 30% larger
- With the larger lens, I would not include the optical viewfinder which is useful but not really accurate. I would invest in a more efficient battery instead. With a better batt capacity, the need for an OVF would not be as pressing.
- I would remove the dedicated dial for Exposure Compensation. Even in dSLR, this is often controlled via the common dial and perhaps activated by a single button on the back of the camera.
- Popup flash, to cater to the bigger lens, there would not be any real estate left for a flash. The space vacated by the Exposure Compensation can be used for this purpose. Something around 6GN(ISO 100) would be more than useful.
- Faster Image Processor and AF performance. I would target something like 3fps with shot to shot time of about 1 sec or faster. Af performance need to be about 0.3s-0.4s
- AF assist lamp. For CDAF focusing system, the Af assist lamp is extremely essential.
- Maintaining 5X magnification Lens from 28mm-140mm and f2.8-4.5 would be beyond usefulness and is almost critical in making this product a success.
- Adapter thread for Wide Angle and Tele converters. I believe a good Wide/Tele converter means that there is no need to change lens. Why would anyone change lens if this camera can cover 24mm-200mm (35mm equiv) and supports Macro. If anyone needs anything more, she should get a dSLR and not complain about weight.
