[Help] D700 Ikelite Housing + What port?

[Lumiere]

Hi everyone.

I'm intending to get an Ikelite UW Housing for my D700
and I intend to use the AFD 35mm f2 and the new AF-S 50mm f1.4G

may i know if I need to use a different dome port for these 2 lenses
and If the housing comes with the dome for 60mm micro...can I use it for my 2 preferred lenses?

Please advice and thanks in advance.

First of all, I'll ask what it is you intend to be photographing with these two particular lenses?
As is, You could use a 6" dome port, but would almost certainly need to add a +4 diopter to enable close focusing.
The Ikelite port guide lists numerous lenses-port applications.

As what Dr Bob says. What do you intend to shoot u/w with those 2 lens? Or are these the lens you already have from shooting on land? From what i know, most nikon shooters will use 60mm micro, 105mm micro, 12-24mm, 10.5mm FE and the popular tokina 10-17 FE (not sure it fits the D700 full frame mount though)

p.s. I think most u/w shooters will use their micro/macro lens behind a flat port instead of a dome.

Hi thanks for replying...

i think i made a mistake betweent the dome and flat port

I understand that most would go for either the fisheye wide uw shots or the micro for the smaller creatures

i intend to use my 35f2 and 50f1.4 for general photography...swimming pool, house reef, in the river etc...not entirely for scuba diving

so please advice again on the flat port...i've tried reading up...but it always gives me the part number for the flat port...

if i intend to use the 35mm and the 50mm can i use the 60mm micro flat port bundled tgt with the housing?

From my understanding, flat ports reduces the incidences of u/w refraction for your shots.

As for the use of your 2 lens behind the flat port for the 60mm micro flat port, you'll need to measure the length of both lens, fully extended. Then check with the ikelite list of ports for the appropriate one.

in short, if the port length fits your lens, it can be used. Hence the advice to measure the length of your lens and compare it to the port chart.

Thanks alot...i'll probably get it at the Adex

I think there will be a lot of vignetting going on if you try and put a 35mm behind a 60mm port. Don't forget that this is an FX chip and can utilise the full 35mm field of view.
6" Dome, all the way

Hmmm why not an 8" dome then?? :dunno:

It's twice the price or more, and not necessary on medium WA (20mm and above).

Also, more practical for snorkelling.

Ahhh icic... But more practical in the long run for u/w photography no? Plus it gives a snorkeller an option to try half/half shots... :think:

Glass-bottom boats are also useful :bsmilie:

 

[Lumiere]

but if i get a 6" Dome...do i need the +4 diopter right? I do not shooting small critters hence i'm a lil confused now

the primary role is to do water surface shots...and nothing more than 15ft deep...subject is human and like those half/half shots...very likely shooting with only available light
lenses used will be 35mm and/or 50mm...

however I will not expel the thought of doing uw photography involving marine life in the future as i am a diver too....but I have to satisfy my pri objective first

 

[Dr Bob]

One of the big problems with underwater photography is visibility...
The use of WA lenses allows us to get closer to subjects whilst keeping the majority of the intended scene in the shot - It's not just macro.
The narrower the field of view, the more one would have to back off to capture the required scene, which allows more water between the sensor and the subject, which affects the overall clarity of the image...
Most lenses in the medium range are subject to effects created by air/glass/water which alter the lens minimum focus (virtual effect) adding a dioptre will reduce the minimum focus by a factor of 2x,3x or 4x, allowing the advantage of getting closer to the subject.
These are not cheap but indispensable.

yes i think you might get quite bad vignetting if you're using the 35/2 in the 60mm port. but generally, if it fits, it'll work. it's just a matter of how well it works.

let me know if you want to get the 6" dome port. i've got one sitting in my cupboard ever since i got my 8" dome.

it'll probably work with both the 35/2 and the 50/1.8 too. you can try it out first before you decide if you want to get it.

True, my 6" dome is also sitting in my dry box haha... :bsmilie:

 

[Dr Bob]

Drop some Viagra in the box too, you may get an extra 2"

 

[Lumiere]

thanks guy...i'll revert back...

I already have one 8", will look kinda wierd with 2 of them... :bsmilie:

Travelling with the 8" Dome is a PITA!!!
But i love it when it produces 50/50s ...
another plus point is that, most curious critters and the occasional fishy comes real close to catch a glimpse of their own reflection in the dome..hopefully its not a nesting Trigger. (underwater creature portraits come impromptu sumtimes)... =)

In my opinion, if you're worried for the cost, then go for the flat ports.
If you want a long-term investment go for the domes, (but mind u, transporting them is err kinda :sweat
