In Topic: G10 w/ Fisheye Lens focus issues

21 October 2009 - 05:32 AM

I've been diving for 5 years and recently upgraded my beginner Sealife DC800 w/ext strobe for a Canon G10 in a FIX housing w/ Sea & Sea YS-110alpha strobe on UL arms. Also have the flip macro lens and a FIX fisheye lens. I was recently in Cozumel diving for the first time with this set-up (less the strobe b/c the airlines lost my bag containing the tray and arms!) and REALLY enjoyed experimenting with the new system and got some great macros. I'm very disappointed in my WA shots though.

I LOVE the perspective I obtained in many shots with the fisheye lens. However, many of my fisheye photos are out of focus and I have no idea why. I was shooting natural light but the ISO/shutter speeds should have been high enough (e.g. f5.6, 1/250 s, ISO 400) that I would not have expected focus to be an issue. I used the center fosus AF mode on the camera. Is there a specific AF mode I should be using to obtain focused images using the fisheye lens????? I expected huge DOF with this lens. My lens was a "loaner" since mine was backordered beyond the date of my trip, but the lens appeared to be in good shape but for one modest scratch on the dome,but perhaps there was something wrong with the lens. Any input/advice would be very appreciated!

Are you shooting in macro mode? I just got a Fantasea fisheye lens for my P5000 and haven't had a chance to get it wet yet, but the manual specifically says to set the camera to macro mode when usung the lens. That's also what I've read in many other parts when it comes to fisheye lens use. If I understand it correctly, it has to do with the dome creating a virtual image right near the dome's surface, so you need to set the camera to focus closely in order to get that "image" in focus.

In Topic: Canon SD90IS, same sensor as G11

The SD90 is a new camera from Canon. I can find it on Canon UK, but not on the US site. Apparently it has the same sensor as the G11. Has any WPer had their hands on one? Do you think Canon will make housing for it?

I'm confident Canon will make a housing for it since, at least according to the specs, the S90 does come with an UW scene mode and an UW white balance setting. Pretty much every camera Canon has made that I know of and has these options also had a Canon housing avialable.

Actually no, they don't. They have an adapter that will allow the AD lenses on some 46mm port housings but NOT on the 67mm port housings and it is the 67mm port housings that both the OP and I are addressing. The adapter I that I made and pictured is for 67mm ports.


Thanks for clearing that up. I wish they'd make these details more readily availabe on their website.

Ikelite makes an adapter for using Inon's AD mount lenses on their housings. It's the #9306.80 Bayonet Mount LINK

Gee, you might want to check my site after I answer your questions...


I checked your site before I asked and couldn't find any mention of it.

Now I see it there and, wow, $99! That's too awesome.
