In Topic: What's wrong with my settings ? (Canon g7x mark II and Inon s2000)

26 March 2018 - 03:52 AM

I'm 100% sure the Inon S2000 magnets are out and have never been in my two Inon S2000 strobes since I bought them.

 

I'm also sure shooting the Canon G7X II in M mode my flash MENU setting has been on AUTO since I bought the camera. I shot with the original Canon G7X for a year before buying a G7X II and have always shot TTL flash on these compacts.

 

In fact, the one reason I bought the original G7X was it was the first canon Powershot that OFFERED TTL flash when shooting in M mode just like SLRs with hot shoe attached flash.

 

I have looked for preflash details in my print and online Canon manual. In P, Tv, Av and M Flash Control menu choices. All info simply labels TTL flash as AUTO.  

 

If there's any preflash difference in AUTO between Av, Tv, P and M modes the Inon S2000 flash automatic (S-TTL) circuitry likely makes the camera's flash to Inon S2000 S-TTL automatically synch.

 

Thousands of shots of my personal experience confirms it works exactly as I describe.

 

One big reason I see people with minimal flash color is usually from shooting too far away. Also closing the aperture down too far as even in S-TTL the flash can only dump a full power max output even automatically plus ISO choice.

 

I lock my ISO at either 125 to a max of 200 unless shooting ambient light only.

 

Just one old guy's information from actual use :)

I looked too and maybe it's the Inon S2000 circuitry that ignores any TTL preflash in any of those modes. 

 

All I know is the way I've used it this way for 2 years. It fires fine and synchs with the camera in TTL and strobe on S-TTL with middle triangular control set to B.

 

Any flash compensation (+/-) I do in camera menu versus on the strobe.

 

Your mileage may vary :)

If your camera flash is set to TTL  my understanding is the Canon camera's flash fires a preflash in M, P, Tv and Av modes.

 

It also does TTL flash in M mode unlike some earlier Canon compact models which had no TTL dash in M mode.

 

Canon G7X II

Camera flash set to TTL 

M Shooting Mode, various shutter speed / f-stop, ISO combinations

 

Inon S2000 strobes on S-TTL middle control in B

No magnets installed

 

At wide and medium focal lengths as some commented you don't need to close down the 1" sensor Canon G7X II aperture too much more than f 5.6.

Macro maybe f8 (and boost ISO to 160) as anything past that introduces more diffraction than any gain in depth of field.

 

I probably stopped these down too much but they came out in focus and well exposed. The camera's TTL flash and Inon S2000 S-TTL flash worked fine.

 

Just one old guy's experience :)
