G1x manual focus, manual exposure still has shutter lag?

[msowsun]

With my G1x set to manual focus and manual exposure, I am still getting shutter lag. Why?

In the past I used this technigue with older P&S cameras and had almost no lag. On the G1x it seems to make no difference to the shutter lag at all.

Any thoughts?

See the I-R Performance tests on the G1 X and G12. The G12 is faster, generally speaking.

"Full autofocus shutter response in the default AF mode tested a bit slower than the G12 at wide-angle, at 0.697 versus 0.656s. At full telephoto, the G1 X was a bit faster than the G12 at 0.681s versus 0.754s, but that's still pretty sluggish by today's standards. Enabling the flash increased shutter lag quite a bit to 1.164s due to the preflash metering involved, also slower than the G12's 0.984s. Shutter lag in manual focus mode was 0.412s. We didn't test that on the G12, but that's quite sluggish compared to most CSCs. "Prefocusing" the camera by half-pressing and holding down the shutter button before the final exposure resulted in a lag time of 0.094s which is reasonably quick, but slower than the G12's 0.076s, and slower than most CSCs.

Overall, the Canon G1 X's autofocus speed and shutter lag are much slower than most recent digicams and CSCs."

I found the problem..... This camera has "Safety MF" in Manual focus which still gives you AF even though you are in MF.

This feature can be turned off and will give much faster shutter response. It is still not instantaneous, but is just as fast as my old P&S cameras were in MF, and is workable when you need a faster response time.
