#393792 What's wrong with my settings ? (Canon g7x mark II and Inon s2000)

Posted by dhaas on 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 :)

Very saddened to hear of this :( A great guy, super talented and certainly pioneered so many ocean imaging techniques. I'll not forget his generosity diving with Blue sharks with him way back when.

#350772 Canon EF-S 10-18mm f/4.5-5.6 STM IS

Posted by dhaas on 24 July 2014 - 12:51 PM

Phil and other interested Canon Rebel SL1 / 100D shooters,


Yes, this is the standard Ikelite port included with the Ikelite housing. There is a dedicated zoom sleeve available now and you put the camera body in and lock the back, then slide the lens and zoom sleeve in  the front.


Slide the port on and you're good to go.  I had full zoom from 10-18mm and with the 1.6X APS-C cropped sensor  it's equivalent to 16mm which is wide enough for me.


More test shots in brighter conditions coming soon.

#350763 Canon EF-S 10-18mm f/4.5-5.6 STM IS

Posted by dhaas on 24 July 2014 - 09:37 AM



Quick shots Tuesday night from a Boy Scouts "Try Scuba" event.......

Shot practically in the dark 8:00 - 9:30 PM pushed to ISO to 800 and of course young boys trying scuba was like herding cats for photos :)
Please ignore any water droplets on the dome, backscatter, hoses and one scuba rig being used in a "politically incorrect" backpack........Was mine I gave up since so many Scouts signed up.......
I confess to not being a 100-200% corner sharpness junkie. As long as the main part(s) of my image is sharp and exposed I simply don't care. the file sizes here may or may not look super defined but on my iMac 21.5" monitor are great.
To each his own!
I think the Canon 10-18mm IS STM lens is great for not only surface shooting but especially wide angle UW images...............Maybe not as sharp in the very extreme corners as a Fisheye but for 95% of my shooting it's fine. 
Being inexpensive and a newer design lens WITH IS (image stabilization) it focuses fast. The photos looks sharper to my eye than the older and more expensive Canon 10-22mm EF-S lens. 
I'll be using it a lot in the Philippines !

#350185 Ikelite Canon 100D / Rebel SL1 : review ?

Posted by dhaas on 12 July 2014 - 06:19 AM



My opinion on WA lens choices is this:


* If you absolutely NEED or WANT the full 10mm of the popular Tokina 10-17mm lens then Bill's dome is tops...........Preset the lens at 10mm and go for it......But zooming the Tokina in to about 11-12mm in the standard Ikelite dome isn't bad either....


* The popular Sigma 15mm Fisheye on a cropped sensor SLR like the Canon Rebel SL1 / 100D is still very nice too........A friend will be shooting his Sigma 15mm in the Philippines on his Canon SL1 early September.


* The Canon 8-15mm F4L lens is super spectacular and can be used in the Ikelite dome preset at one focal length......I shot it at 12mm in the Ikelite dome and was very happy with the results. Bill may make a "tuned" version of his dome for this lens too.


* Finally, the inexpensive Canon 10-18mm IS STM rectilinear lens will be a great choice for Canon Rebel SL1 / 100D shooters..........It's a great surface lens and while not as wide as the fisheye choices will work well for land and UW shooters wanting to own one WA lens.....


Sample pics below from some of the fisheye choices.........First 4 pics Tokina 10mm in Bill's dome, then Sigma 15mm Fisheye (1 shot) and then a Canon 8-15mm Fisheye at 12mm (1 shot).


Also some more photos at this link. Same group of WA lenses and even some Canon 18-55mm IS STM "kit" lens shots.......A darn capable little camera....

#347348 Ikelite Canon 100D / Rebel SL1 : review ?

Posted by dhaas on 06 May 2014 - 05:12 PM

Phil (and Bill),


Actually the Canon SL1 has a Hybrid CMOS AFII newer version autofocus than the T5i......Yes, the T5i has all cross type 9 AF points versus the SL1 having the center point of 9 total being a cross type. But in real world shooting the SL1 is more than fast enough (I owned the T4i for a year, same AF specs as the T5i.)


The included dome port will fit the following lenses physically: Canon 18-55mm IS STM kit lens, Tokina 10-17mm Fisheye, Sigma 15mm Fisheye and even the Canon 8-15mm F4L Fisheye. I'll have all with me on Bonaire next week so we'll see how this tiny SLR does in real world shooting........Along with the Canon 60mm Macro lens many if not most Canon SL1 shooters won't nee much more......


I think Bill may be alluding to many of us in the "F" days (film) used a lowly Nikonos III or V with great glass and that's what really makes the photo........Plus time in the water of course :)


This housing is designed to keep it simple and deliver great pics.......


Stay tuned..............

#329334 Ikelite 8" or 6" Dome Port for GW Sharks

Posted by dhaas on 07 April 2013 - 03:57 PM

6" port especially with Tokina 10-17mm and you'll get no vignetting by 12mm on a Canon 1.6X crop APS-C sensor with shade is fine.


Smaller port is much easier to maneuver in cage windows too.


Good shooting!

#328771 Planned ban of underwater cameras in Sipadan

Posted by dhaas on 28 March 2013 - 10:59 AM

Better plan would be to disconnect any divers inflator and see if they can dive and stay off the reef with or without any type of camera :(


No diver is perfect and anyone who claims to never have touched bottom, coral, etc. isn't honest or never dives. The difference is being aware and working to keep the environment healthy by not inflicting damage you can control.


Sport diving training today is in a sad state with gear and money replacing practice and watermanship....


Not thrilled as I wanted to go there someday but I understand some of the reaction and trying to let the area rebound.
