Generally a speil about how good and compact they are reinforcing lens / port compatability.

No specifactions for the simple model were stated other that it being available at end of june. :?: THis was the big point.

My guess is defeatured in controls from the main housing and less control from the back plate.

Excuse my poor translation

Optional controls on the D70s, which are all available standard on the d70 housing, include:

Focus mode selection
Lens release lever
Mode dial control
AE/AF lock lever
Second strobe socket
Focus area control lock switch
Whitebalance control (I think!)

I'm not entirely sure what "modulated light mode" or "photographing operation" refer too.

I would recommend getting one w/ an AF-lock control.

James, what's your reasoning on this one? I use the old tried and true method. AF with half depress, recompose and depress all the way. Should I be using the AF lock?:wink: Am I stuck in a obsolete habit?

Actually, I've done some reading on Canon E-TTL. The Canon biases the fill flash amount toward the focus point. Some users have complained about poor flash exposure because they used the point-focus-recompose technique.

Hi George,

Yes, Canon's eTTL is not the same as Nikon's multi-sensor balanced fill-flash (yes, I own and have read Thom's Nikon flash guide :-) It's not as good.

On the AF lock - I recently tried the D100 is the Titan housing, which has an AF-lock button on the handgrip. Other housings have access to the AF button on the camera also. If you set up this button to lock focus, you can press it, take your finger off, and focus will still remain locked. Since you have the Aquatica housing (I'm assuming) you haven't gotten a chance to try it yet. But you will - and then you'll love it.

It's the bee's knees for shooting macro w/ the 105 or the 70-180 'cause you can leave the lens in auto. Focus on something close, press the button and cruise over to your subject. For Nikon's macro lenses which have the A-M shift collar (in other words, all of them) this is a really nice feature that's a "half-way" between auto and manual focus.

James, I'm still trying to get my hands around using the AF Lock button on my D70 housings.....I'm very used to the half depress method and am very comfortable with it...

I'm not sure I understand the advantage of pushing the AF lock button and then depressing the shutter....it seems to me that my focus distance could move as I wait to compose, etc.....are you saying that once I've locked the focus on a macro subject and move the focus point, the focus tracking follows the new path and keeps the subject in focus?

That seems to good to be true :lol:

We're going to the FG's this weekend for our first dives with the new equipment. Should be interesting. :wink:

Hi Karl,

No, that's not really what I meant.

You'll find that when you focus on a macro subject, say it's a blenny, you'll probably get focus somewhere on the body of the fish. So you'll have to lock focus, (using AF lock, or shutter half-press) then pull back a bit to get the eyes in focus. Try it this weekend, you'll see what I mean.

When people say "critical focus" this is what they're talking about. It's very important for macro.

Make sure you are using single servo focus if you are locking with half press...

I would use Continuous Servo, and lock with AF Lock, if I used AF.

I would also turn the dynamic AF off- it will frustrate you.

One focus strategy for people who are comfortable with half pressing their camera through the housing is to us half press to start af, and lock when focus either locs on part of the subject (as James said), or gets in the ball park. From there, you have to achieve critical focus by moving the camera back and forth (while holding AE-L/AF-L).

Another strategy is to configure the AE-L/AF-L button in the menu to be AF-ON. The eliminates the prefocus function of the shutter release. The camera will only AF when you press it down. The advantage of this is that when you release the button, focus is locked (so you don't have to hold down AF-L while recomposing/fine focusing). This is also good for people who don't have the most nimble fingers.

sorry folk to make a little discussion about focus lock. Actually I have use
nexus master for my f90x for 10 years and I always work with focus lock
on my finger But for new model like d100 and f100 I don't understand why they change to focus lock position and it's impossible for my hand(Asia people) to grab a camera press the shutter and lock the focus together for my old master it's perfect control I can shoot the hold roll with focus lock within a minute
