Canon G11 or S90

[i-link]

I'm thinking of getting either a G11 or S90, anyone can advise me?
as for S90, as I not getting the stroke light, does the casing let the popup flash to be use?

 

[ponders]

for me i prefer the S90 as it is a compact camera with a f/2.0 lens.

i read somewhere the S90 casing comes with a Flash diffusing card like any other casing. so i guess the flash could be popped up underwater

If canon made a casing till the control-ring is functional underwater.. i guess the flash is not a problme...

so with a f2.0, is it faster to capture image? then what does G11 has? f2.8?
any more suggestion?
what do you mean by the control ring? the one behind or front?
I should be getting the ikelite casing, so I dont know if the casing has it?
still thinking either G11 or S90?

for the same light conditions.. f2 is able to use a higher shutter speed than a f2.8.

i dunno how much light difference is there, but when i read reviews.. f1.8 is 4 times more light as f3.5 of the same focal length. Since f-number is a ratio of the diameter to focal length (correct me if i am wrong).

the control ring is the one in front on the lens.

I have yet to hold a S90 myself, but i see it as a very promising camera.

you may want to read what www.kenrockewell.com has to say about it.

its one stop, which lets twice the amount of light in. thus s90 can take a picture at twice the speed from that of g11 at the wide end. g11 does have a larger zoom range mind you :bsmilie:

Yup, but for me i don't really zoom underwater. But that's just me.

But i don't think the at the longest zoom, the shutter speed at underwater available light would support a clear shot.

so s90 is a better camera than a g11 in water? lol

 

[ponders]

technically.. G11 and S90 share the same sensor

as to which is a better camera, it really depends on you.

S90 for small size, f2.0, "simple"

G11 for if you want at a later date go Strobe, etc. but the UW casing is BIG

got this website from kenrockwell website... g11 is really super

wow, the photos were really good, how about underwater shots?

You will need to work around certain limitations of the housings (canon/ikelite) which do not support the use of the jog dial. Switching of settings is a bit more troublesome. The canon housing's shutter release button does not have much tactile feedback so half-shutter may be hard to feel when using the canon housing. As for u/w shots, i believe the G11 has the same or better potential as the G10.

I noticed the lack of tactile feedback on the G10 casing.

Just want to see if people agree with me, the lack of tactile feedback is due to the amount of air inside the G10 is is compressed underwater hence there is a "vacuum" slowing down the return of the button.

I don't own a G10, i have suggested my friend to fill all empty air space with silica gel or any solid matter. Haven't got back to me yet...

nope, the air in the housing is still at 1 atm pressure, simply because it is a rigid case. the lack of tactile feedback is due to the springs and the use of a button instead of a shutter release lever

you might want to read up a little on the physics of diving..it will give you a much better understanding of the activity and how it affects you underwater.

of course, you can always fill up the inside with water to make sure there is no empty air space in the housing?

That's where i am not sure, air inside an enclosed space (say a sealed bottle) would compress as we go deeper. although I am not sure this happens because of the pressure acting on it, or the air actually compressing.

So i "theorise" (whether i am right/wrong i dunno) that the air in the casing would compress just as the bottle would.

I notice this in the G10 casing i borrowed. And also a 860 casing around 30-35m.

yep.. the physics of diving i learnt so far is what PADI taught me... looks like i should go for a refresher. haha.

I m also thinking whether to get S90 or G11 but I am doing land photography and want a compact camera but with SLR like features

 

[i-link]

Let's get the G11 together!!! haha
i think i will stick to G11, since I already tried G10 u/w.

 

[ponders]

I am for S90 camp

Getting mine next month...

I think i don't like about G10 is the humongous size on top of my dive gear.

however, i have no complains about G10s capability for use underwater.

Another important factor one why i chose S90 is I don't see what G11 can do that S90 cannot do. (the upper end of focal length is indifferent to me).

ponders, i read some of the post, thought u are a lumix user? since u already did some underwater shot, mayb u can advise me on photography underwater! lol
maybe can get our camera together also haha, although u getting S90, i getting G11! lol, or maybe i will change my mind!

 

[i-link]

another question for the public to help me solve,
which u/w case should i get, canon original or ikelite? what is the difference?
I tried a G10 before, original canon casing.. so i suppose the G11 is abt the same. how abt ikelite?
i know 60m, what else?
I read that a lot of u/w shots need lights, so if i really get stroke light, both casing can mount isit?
price of ikelite = 2 x canon original + a bit $ = damn ex.. lol

Hi, I am currently using G9 for u/w macro photography (http://www.whoiskarenchen.com/underwater.php), and I'm very happy with its performance. My u/w gear: original Canon u/w casing with 1 x Inon strobe D-2000 with flexiarm.
Prefer original casing cos it is affordable and I personally find Ikelite too square in design.
One can get wide angle or macro lens for canon original u/w casing too (http://www.divephotoguide.com/news/fantasea_announces_wide_angle_macro_lenses_for_the_canon_g11).
You will need to get a tray to secure the u/w housing and strobe arms (http://www.oceanicfocus.com/catalog/images/INON+ULCS.gif).

I am purchasing my G11 soon cos it's got a good review (http://www.divephotoguide.com/artic..._of_the_line_compact_camera_the_powershot_g11).

Feel free to email me if you got any more queries... cheers!
